Indiana Patent Litigation: Lilly Sues Alleging Infringement of ALIMTA

LillyIndianapolisPicture.png

Indianapolis, Indiana - An Indiana patent attorney for Eli Lilly and Company of Indianapolis, Indiana ("Lilly") and The Trustees of Princeton University of Princeton, New Jersey ("Princeton") filed a patent infringement complaint in the Southern District of Indiana alleging that Nang Kuang Pharmaceutical Co., Ltd. of Tainan City, Taiwan and CANDA NK-2, LLC of Waco, Texas infringed and/or will infringe ALIMTA®, U.S. Patent Nos. 5,344,932 ("the '932 patent") and 7,772,209 ("the '209 patent"; collectively, "the patents-in-suit"), which have been issued by the U.S. Patent Office.

ALIMTA, which is licensed to Lilly, is a chemotherapy agent used for the treatment of various types of cancer. ALIMTA is composed of the pharmaceutical chemical pemetrexed disodium. It is indicated, in combination with cisplatin, (a) for the treatment of patients with malignant pleural mesothelioma, or (b) for the initial treatment of locally advanced or metastatic nonsquamous non-small cell lung cancer. ALIMTA also is indicated as a single agent for the treatment of patients with locally advanced or metastatic nonsquamous non-small cell lung cancer after prior chemotherapy. Additionally, ALIMTA is indicated for maintenance treatment of patients with locally advanced or metastatic nonsquamous non-small cell lung cancer whose disease has not progressed after four cycles of platinum-based first-line chemotherapy. One or more claims of the '209 patent cover a method of administering pemetrexed disodium to a patient in need thereof that also involves administration of folic acid and vitamin B12. The '932 patent, titled "N-(pyrrolo(2,3-d)pyrimidin-3-ylacyl)-Glutamic Acid Derivatives," along with the '209 patent, have been listed in connection with ALIMTA in the FDA's publication Approved Drug Products with Therapeutic Equivalence Evaluations.

This Indiana patent infringement lawsuit arises out of the filing by Defendant Nang Kuang of an Abbreviated New Drug Application ("ANDA") with the U.S. Food and Drug Administration ("FDA") seeking approval to manufacture and sell generic versions of ALIMTA prior to the expiration of the '932 and '209 patents. Nang Kuang filed as a part of that ANDA a certification of the type described in Section 505(j)(2)(A)(vii)(IV) of the Food, Drug and Cosmetic Act, 21 U.S.C. § 55(j)(2)(A)(vii)(IV), with respect to the patents-in-suit, asserting that the claims of the patents-in-suit are invalid, unenforceable, and/or not infringed by the manufacture, use, offer for sale, or sale of Defendants' ANDA products.

In their complaint, filed by an Indiana patent lawyer, Lilly and Princeton state that Defendants intend to engage in the manufacture, use, offer for sale, sale, marketing, distribution, and/or importation of Defendants' ANDA products and the proposed labeling therefor immediately and imminently upon approval of the ANDA i.e., prior to the expiration of the patents-in-suit. Plaintiffs asserts that Defendants' actions constitute and/or will constitute infringement of the patents-in-suit, active inducement of infringement of the patents-in-suit, and contribution to the infringement by others of the patents-in-suit.

The complaint, filed by an Indiana patent lawyer, lists the following claims:

  • Count I: Infringement of U.S. Patent No. 5,344,932
  • Count II: Infringement of U.S. Patent No. 7,772,209

Lilly and Princeton ask the court for:

(a) A judgment that Defendants have infringed the '932 patent and/or will infringe and/or actively induce infringement of the '932 patent;

(b) A judgment ordering that the effective date of any FDA approval for Defendants to make, use, offer for sale, sell, market, distribute, or import Defendants' ANDA Products, or any product the use of which infringes the '932 patent, be not earlier than the expiration date of the '932 patent, inclusive of any extension(s) and additional period(s) of exclusivity;

(c) A preliminary and permanent injunction enjoining Defendants, and all persons acting in concert with Defendants, from making, using, selling, offering for sale, marketing, distributing, or importing Defendants' ANDA Products, or any product the use of which infringes the '932 patent, or the inducement of any of the foregoing, prior to the expiration date of the '932 patent, inclusive of any extension(s) and additional period(s) of exclusivity;

(d) A judgment declaring that making, using, selling, offering for sale, marketing, distributing, or importing of Defendants' ANDA Products, or any product the use of which infringes the '932 patent, prior to the expiration date of the '932 patent, infringes, will infringe and/or will actively induce infringement of the '932 patent;

(e) A judgment that Defendants have infringed the '209 patent and/or will infringe, actively induce infringement of, and/or contribute to infringement by others of the '209 patent;

(f) A judgment ordering that the effective date of any FDA approval for Defendants to make, use, offer for sale, sell, market, distribute, or import Defendants' ANDA Products, or any product the use of which infringes the '209 patent, be not earlier than the expiration date of the '209 patent, inclusive of any extension(s) and additional period(s) of exclusivity;

(g) A preliminary and permanent injunction enjoining Defendants, and all persons acting in concert with Defendants, from making, using, selling, offering for sale, marketing, distributing, or importing Defendants' ANDA Products, or any product the use of which infringes the '209 patent, or the inducement of or contribution to any of the foregoing, prior to the expiration date of the '209 patent, inclusive of any extension(s) and additional period(s) of exclusivity;

(h) A judgment declaring that making, using, selling, offering for sale, marketing, distributing, or importing of Defendants' ANDA Products, or any product the use of which infringes the '209 patent, prior to the expiration date of the '209 patent, infringes, will infringe, will actively induce infringement of, and/or will contribute to the infringement by others of the '209 patent;

(i) A declaration that this is an exceptional case and an award of attorneys' fees pursuant to 35 U.S.C. § 285; and

(j) An award of Plaintiffs' costs and expenses in the action.

Practice Tip #1: This summer, Lilly succeeded in defending the '209 method-of-use patent in before District Judge Tanya Walton Pratt in the Southern District of Indiana. The court found, inter alia, that the patent did not fail for "obviousness."

Practice Tip #2: Obviousness is a legal conclusion based on underlying factual findings. Such findings include: 1) the scope and content of the prior art; 2) the differences between the claims and the prior art; 3) the level of ordinary skill in the art; and 4) objective considerations of non-obviousness such as commercial success and satisfaction of a long-felt need. Moreover, it is insufficient that prior art merely includes separate references to the subject matter of a subsequent patent claim. Instead, obviousness requires the additional showing that a person of ordinary skill in the art of the subject matter would have combined those elements of the prior art.

Indiana Trade Secret Law: Removing Allegation of Theft of Trade Secrets Results in Defendants' Release from "Lockdown"

secret-300x237.jpgIndianapolis, Indiana - In 2013, a federal indictment including counts of theft of trade secrets belonging to Eli Lilly and Company ("Lilly") was presented to the Southern District of Indiana. On the basis of this indictment, the court ordered Defendants Guoqing Cao and Shuyu Li, formerly employed by Eli Lilly and Company, to be detained at housing provided by Volunteers of America - Indiana ("VOA"), pending their criminal trial. When the 2013 indictment was superseded by a second indictment that did not include counts for the theft of trade secrets, the court granted Defendants' request to be released to home detention.

On August 14, 2013, Defendants Cao and Li, two doctoral-level scientists formerly employed by Lilly, were charged with multiple counts of theft. At issue was intellectual property belonging to Lilly valued at $55 million. Counts one through three of the indictment, as well as counts five through ten, were listed as theft of trade secrets and aiding and abetting. Count four alleged conspiracy to commit theft of trade secrets.

In the initial proceedings, the United States maintained that the Defendants were traitors who had conveyed "American trade secrets" - specifically, "crown jewels" in the form of many millions worth of intellectual property belonging to Lilly - to Jiangsu Hengrui Medicine Co., Ltd., a company located in Shanghai, China. These arguments strongly impacted the court's decision to order "lockdown" detention at the VOA.

A second indictment was later filed by the United States. Under the new indictment, the Defendants faced no charges of trade-secret theft. Instead, they were charged with one count each of wire fraud, aiding and abetting, and conspiracy to commit wire fraud. Based on the absence of allegations relating to trade-secret theft in the subsequent indictment, the Defendants asked the court to modify the terms of their detention.

The court was persuaded that such a change was warranted. It noted that there was "a difference between allegations of 'theft of trade secrets' and disclosure of 'Lilly Property.'" It further stated that the earlier allegation - that Lilly's "crown jewel" secrets had been stolen and provided to China - had been a critical factor in justifying the Defendants' incarceration.

When the allegations of trade secret misappropriation were removed, the court found that those justifications were no longer applicable: "No longer are the Defendants accused of stealing 'trade secrets'--those words are found nowhere in the superseding indictment" and released the Defendants from lockdown to the less-restrictive conditions of home detention.

Practice Tip #1: Nine Lilly trade secrets pertaining to pharmaceuticals under development for cardiovascular disease, diabetes and cancer were at issue in this Indiana criminal prosecution for theft of intellectual property.

Practice Tip #2: Defendants' home detention restricts individuals to their residence at all times except for employment; education; religious services; medical, substance abuse, or mental health treatment; attorney visits; court appearances; court-ordered obligations; or other activities approved in advance by the pretrial services office or supervising officer. Defendants were also ordered not to access or use any internet-enabled device with the exception of utilizing email to communicate with counsel.

Lilly Successful in Defending Alimta Method-of-Use Patent

AltimaPicture.bmpIndianapolis, Indiana - In conjunction with co-counsel, an Indiana patent attorney for Eli Lilly of Indianapolis, Indiana prevailed in the Southern District of Indiana on claims of patent infringement. At issue was Lilly's patent on the use of Alimta® in conjunction with specific vitamins. District Judge Tanya Walton Pratt concluded that Defendants Teva Parenteral Medicines, Inc. of Irvine, California; APP Pharmaceuticals, LLC of Schaumburg, Illinois; Pliva Hrvatska D.O.O. of Zagreb, Croatia; Teva Pharmaceuticals USA Inc. of North Wales, Pennsylvania; and Barr Laboratories, Inc. of Montvale, New Jersey failed to prove invalidity of U.S. Patent No. 7,772,209 (the "'209 Patent") and entered judgment in favor of Lilly.

Lilly sells the drug Alimta ("pemetrexed"), a chemotherapy drug, to treat various types of lung cancer, including mesothelioma. However, certain side effects were troublesome, including treatment-related hematologic and gastrointestinal toxicity. Deaths among some patients were attributed to treatment with pemetrexed. In response to this concern, Lilly took the unusual step of mandating supplementation of the pemetrexed protocol with two vitamins - folic acid and vitamin B12. The patentability of that idea was the focus of a patent challenge - this litigation - by five manufacturers of generic drugs.

Lilly's '209 Patent describes a method of using an antifolate, pemetrexed, with vitamins. Antifolates are a type of chemotherapy drug used to treat certain types of cancer. They work by competing with folates, a class of essential nutrients that includes folic acid. By interfering with the action of folates, antifolates thereby deprive cancer cells of the DNA precursors they need to proliferate.

The generic challengers contended in part that the patent on the combined therapy is invalid, arguing that someone knowledgeable about both nutrition and medicine could have easily concluded that supplementation with B12 and folate might alleviate certain side effects of pemetrexed.

Lilly, in contrast, argued that the vitamin regimen was not only counterintuitive when it was proposed, it was called "crazy" by a leading cancer doctor before testing showed its benefits.

Lilly prevailed. The court found that Defendants failed to show by clear and convincing evidence that the asserted claims of the '209 Patent were invalid for obviousness, obviousness-type double patenting, inadequate description or lack of enablement. Thus, the '209 Patent is valid and enforceable.

The '209 Patent is presumed to be valid under 35 U.S.C. § 282. Defendants, as the parties challenging the validity of the '209 Patent, bore the burden of proving invalidity by clear and convincing evidence.

Defendants' first contention was that the '209 Patent was obvious. To prove obviousness, they would have to show by clear and convincing evidence that the differences between the claims and the prior art at the time the invention were such that, considered as a whole, the claims would have been obvious to a person of ordinary skill in the art ("POSA") in that subject matter.

Obviousness is a legal conclusion based on underlying factual findings. Such findings include: 1) the scope and content of the prior art; (2) the differences between the claims and the prior art; (2) the level of ordinary skill in the art; and (4) objective considerations of non-obviousness such as commercial success and satisfaction of a long-felt need. Moreover, it is insufficient that prior art merely includes separate references to the subject matter of a subsequent patent claim. Instead, obviousness requires the additional showing that a POSA would have combined those elements of the prior art. Thus, Defendants in this case bore the burden of proving that a POSA would have had reason to (1) administer folic acid pretreatment with pemetrexed, (2) administer vitamin B12 pretreatment with pemetrexed, and (3) administer each of them according to the doses and schedules indicated in the '209 Patent.

The court first found that folic pretreatment with pemetrexed was not obvious. Among its findings were that the prior studies on mice would not have led a POSA to consider such supplementation. There would have been considerable difficulty in comparing studies on the combined treatment in mice with effects likely to be observed in humans, given the differences between humans and mice. One substantial difference was that mice have much higher requirements for folic acid. As an additional confounding factor, the studies on mice given low-folate diets were only possible because the mice were also given an antibiotic to prevent bacteria in the intestines of the mice from making folic acid that would otherwise raise a mouse's level of folic acid.

These and other differences would have represented substantial obstacles in making the leap from the prior state of understanding of vitamin supplementation with antifolates to the claims of the '209 Patent. The court thus held that a POSA reviewing the prior art, instead of concluding that the supplementation was useful, would have likely concluded that supplementation decreased the efficacy of the drug. Consequently, those prior studies would have resulted in a "teaching away" from the claimed invention by discouraging a POSA from pursuing vitamin supplementation in conjunction with pemetrexed.

The court concluded that, likewise, vitamin B12 pretreatment with pemetrexed was not obvious and that, as of June 1999, a POSA would have expected that vitamin B12 would counteract the efficacy of antifolates. Instead, the court held that the benefit of using B12 in conjunction with pemetrexed was not discovered until late 1999, when a mathematician for Lilly ran an extensive statistical analysis of data from patients in the worldwide, phase-III pemetrexed trial.

The court next held that the doses and schedules within the claims asserted by Lilly were not obvious. The vitamin dosing regimens attempted in the prior art, which contained folic acid only, reduced the efficacy of pemetrexed as compared to unsupplemented trials. However, the regimen in the '209 Patent actually improved the efficacy of the drug over unsupplemented clinical trials. While normally a change in temperature, concentration or both would be an unpatentable modification, patentability may be found if the results of such a change are "unexpectedly good." The court held that the changes resulting from the methods described in the '209 Patent fell within this exception to the general rule.

The scheduling of the pretreatment with the vitamin supplementation was also deemed non-obvious by Judge Walton Pratt, as prior studies had shown that administration of folic acid one week prior to the administration of lometrexol (another chemotherapy agent) reduced the efficacy of the drug and was a cause of concern for oncologists. Based upon the results of that study, a POSA would have not have anticipated a likelihood of success with pretreatment with vitamins.

In its evaluation of non-obviousness, the court last considered secondary indicia of non-obviousness of the asserted claims of the '209 Patent. These indicia include the commercial success of the invention at issue and its satisfaction of a long-felt need; skepticism or disbelief before the invention; failure of others and evidence of unexpected properties. It found these indicia supported a conclusion of non-obviousness.

Finally, the court held that the claims at issue were not invalid for obviousness-type double patenting, concluding that the claims asserted in the '209 Patent were patentably distinct from Lilly's U.S. Patent No. 5,217,974 (the "'974 Patent"). The court included in its reasoning that the '974 Patent discloses, inter alia, the use of a much greater amount of folic acid, does not reference pemetrexed and includes nothing about pretreating with vitamin B12.

Consequently, the court found that the asserted claims of the '209 Patent were valid and enforceable, and entered judgment in favor of Lilly and against Defendants.

Practice Tip #1:

Patent-infringement litigation between brand-name manufacturers and generic-drug makers is common. In a typical lawsuit, a company that wishes to sell a generic version of a brand-name drug, usually a widely used drug, will try to invalidate the patent on the drug, in the hopes that it could then offer the same drug in generic form.

This litigation was different from traditional patent litigation. The original patent on Alimta, administered as a stand-alone treatment, protects only Alimta's active ingredient. That patent will expire in 2017. However, the focus of the current litigation was on the combination treatment - a "method-of-use patent" - that involves both Alimta and the vitamin regimen.

Practice Tip #2:

Because the '209 Patent was upheld, the period of exclusivity for Alimta, in conjunction with the vitamin supplementation, now expires in 2022. In 2013, Lilly earned revenues of $2.7 billion from global sales of Alimta. Thus, the extra five years of patent protection may result in additional revenues in excess of $10 billion for Lilly.

Indiana Patent Litigation: Lilly Brings Another Defendant into Effient Patent Infringement Litigation

Indianapolis, Indiana - In conjunction with co-counsel from Washington, D.C., an Indiana patent attorney for Eli Lilly and Company of Indianapolis, Indiana; Daiichi Sankyo Co., Ltd of Tokyo, Japan; Daiichi Sankyo, Inc. of Parsippany, New Jersey; and Ube Industries, Ltd. of atrial-fibrillation-s3-photo-of-heart-rhythm.jpgYamaguchi, Japan sued in the Southern District of Indiana alleging that First Time US Generics LLC of Broomall, Pennsylvania infringed Effient® products, Patent Nos. 8,404,703 and 8,569,325 which have been issued by the U.S. Patent Office.

This is a civil action for patent infringement. It arises out of the filing by Defendant First Time US Generics LLC ("FTUG") of an Abbreviated New Drug Application ("ANDA") with the United States Food and Drug Administration ("FDA") seeking approval to manufacture and sell generic versions of two of Lilly's pharmaceutical products, Effient® 5mg and Effient® 10mg tablets, prior to the expiration of Daiichi Sankyo's and Ube's U.S. patents, which purportedly cover methods of using Effient® products. Plaintiffs assert that Lilly holds an exclusive license to these products. DSI currently co-promotes Effient® products in the United States with Lilly.

Effient® products were approved by the FDA for the reduction of thrombotic cardiovascular events in certain patients with acute coronary syndrome (ACS) who are to be managed with percutaneous coronary intervention (PCI, or angioplasty). The instructions accompanying Effient® products state that patients taking Effient® products should also take aspirin. The use of Effient® products in combination with aspirin for the reduction of thrombotic cardiovascular events in patients with ACS who are to be managed with PCI is covered by the claims of the '703 and '325 patents.

FTUG has submitted an Abbreviated New Drug Application (the "FTUG ANDA") to the FDA pursuant to 21 U.S.C. § 355(j), seeking approval to market a generic version of Lilly's product for oral administration (the "FTUG Products") in the United States.

Plaintiffs assert that FTUG will knowingly include with the FTUG Products instructions for use that substantially copy the instructions for Effient® products, including instructions for administering the FTUG Products with aspirin as claimed in the '703 and '325 patents. Moreover, Plaintiffs contend that FTUG knows that the instructions that will accompany the FTUG Products will induce and/or contribute to others using the FTUG Products in the manner set forth in the instructions. Plaintiffs also contend that FTUG specifically intends that health care providers, and/or patients will use the FTUG Products in accordance with the instructions provided by FTUG to directly infringe one or more claims of the '703 and '325 patents. FTUG therefore will actively induce and/or contribute to infringement of the '703 and '325 patents, state Plaintiffs.

In the complaint, the Indiana patent lawyer for Plaintiffs listed the following counts:

• Count I: Infringement of U.S. Patent No. 8,404,703
• Count II: Declaratory Judgment of Infringement of U.S. Patent No. 8,404,703
• Count III: Infringement of U.S. Patent No. 8,569,325
• Count IV: Declaratory Judgment of Infringement of U.S. Patent No. 8,569,325

Plaintiffs ask the court for judgment:

A. That FTUG has infringed or will infringe, after the FTUG ANDA is approved, one or more claims of the '703 patent;
B. That FTUG has infringed or will infringe, after the FTUG ANDA is approved, one or more claims of the '325 patent;
C. That, pursuant to 35 U.S.C. § 271(e)(4)(B), FTUG and its agents be permanently enjoined from making, using, selling or offering to sell either or both of the FTUG Products within the United States, or importing either or both of the FTUG Products into the United States prior to the expiration of the '703 and '325 patents;
D. That, pursuant to 35 U.S.C. § 271(e)(4)(A), the effective date of any approval of the FTUG ANDA under § 505(j) of the Federal Food, Drug and Cosmetic Act (21 U.S.C. § 355(j)) shall not be earlier than the latest of the expiration dates of the '703 and '325 patents, including any extensions;
E. If FTUG commercially makes, uses, sells or offers to sell either or both of the FTUG Products within the United States, or imports either or both of the FTUG Products into the United States, prior to the expiration of either of the '703 and '325 patents, including any extensions, that Plaintiffs will be awarded monetary damages for those infringing acts to the fullest extent allowed by law and be awarded prejudgment interest based on those monetary damages;
F. That this case be deemed exceptional under 35 U.S.C. § 285
G. Declaring that the '703 patent remains valid and enforceable;
H. Declaring that the '325 patent remains valid and enforceable; and
I. That Plaintiffs be awarded reasonable attorney's fees, costs and expenses.

Practice Tip:

In March 2014, Lilly et al. filed a 101-page complaint making similar accusations against more than thirty defendants: Accord Healthcare, Inc. USA; Accord Healthcare, Inc.; Intas Pharmaceuticals Ltd.; Amneal Pharmaceuticals LLC; Amneal Pharmaceuticals of New York, LLC; Amneal Pharmaceuticals Co. India Pvt. Ltd.; Aurobindo Pharma Limited; Aurobindo Pharma USA Inc.; Dr. Reddy's Laboratories, Ltd; Dr. Reddy's Laboratories, Inc.; Glenmark Generics Inc., USA; Glenmark Generics Ltd.; Glenmark Pharmaceuticals Ltd.; Hetero USA Inc.; Hetero Labs Limited; Hetero Labs Limited Unit V; Hetero Drugs Ltd.; Mylan Pharmaceuticals Inc.; Mylan Inc.; Mylan Laboratories Limited; Par Pharmaceutical Companies, Inc.; Par Pharmaceutical, Inc.; Sun Pharma Global FZE; Caraco Pharmaceutical Laboratories, Ltd.; Sun Pharma Global Inc.; Sun Pharmaceutical Industries, Ltd.; Teva Pharmaceuticals USA, Inc.; Teva Pharmaceutical Industries, Ltd.; Watson Laboratories, Inc.; Actavis plc; Actavis, Inc.; Actavis Pharma, Inc.; Zydus Pharmaceuticals USA, Inc.; and Cadila Healthcare Ltd. d/b/a Zydus Cadila.

FTUG is the latest of addition to Lilly's list of defendants in the Effient litigation. In contrast to the March complaint against 30-plus mostly unrelated defendants, FTUG, as well as the other subsequent unrelated defendants, have been added via separate complaints alleging patent infringement.

Indiana Patent Litigation: HEC Pharm Added to Effient Patent Infringement Litigation

Indianapolis, Indiana - An Indiana patent attorney for Eli Lilly and Company of Indianapolis, Indiana; Daiichi Sankyo Co., Ltd of Tokyo, Japan; Daiichi Sankyo, Inc. of Parsippany, New Jersey; and Ube Industries, Ltd. of Yamaguchi, Japan sued in the Southern District of Indiana alleging that HEC Pharm Co., Ltd. of China and HEC Pharm USA Inc. of Princeton, New Jersey (collectively, "HEC Pharm") infringed Lilly's patented Effient® product, Patent No. 8,404,703, which has been issued by the United States Patent Office.

patentpicture.bmpThis lawsuit adds another defendant, HEC Pharm, to Lilly's Indiana patent litigation regarding Effient. In these Effient patent-defense lawsuits, Lilly et al. allege infringement of certain patents related to the pharmaceutical Effient. At issue in the litigation against HEC Pharm is only one of the Effient-related patents, 8,404,703 "Medicinal Compositions Containing Aspirin," (the "'703 patent").

This complaint asserts patent infringement arising out of the filing by HEC Pharm of an Abbreviated New Drug Applications ("ANDA") with the United States Food and Drug Administration ("FDA") seeking approval to manufacture and sell generic versions of two pharmaceutical products - Effient 5mg and Effient 10mg tablets - prior to the expiration of the '703 patent. These patents cover a method of using Effient products for which Lilly claims an exclusively license.

Effient products were approved by the FDA for the reduction of thrombotic cardiovascular events in certain patients with acute coronary syndrome (ACS) who are to be managed with percutaneous coronary intervention (PCI, or angioplasty). Effient products contain prasugrel hydrochloride, which is also known as 5-[(1RS)-2-cyclopropyl-1-(2-fluorophenyl)-2-oxoethyl]-4,5,6,7-tetrahydrothieno[3,2-c]pyridin-2-yl acetate hydrochloride.

The instructions accompanying Effient products state that patients taking Effient products should also take aspirin. The use of Effient products in combination with aspirin for the reduction of thrombotic cardiovascular events in patients with ACS who are to be managed with PCI is allegedly covered by the claims of the '703 patent.

HEC Pharm is accused of planning to infringe the patents-in-suit by including with its products instructions for use that substantially copy the instructions for Effient products, including instructions for administering HEC Pharm's products with aspirin as claimed in the '703 patent.

Plaintiffs contend that HEC Pharm knows that the instructions that HEC Pharm intends to include with its products will induce and/or contribute to others using those products in the allegedly infringing manner set forth in the instructions. Moreover, Lilly et al. also contend that HEC Pharm specifically intends for health care providers, and/or patients to use HEC Pharm's products in accordance with the instructions provided by HEC Pharm and that such use will directly infringe one or more claims of the '703 patent. Thus, state Plaintiffs, HEC Pharm's actions will actively induce and/or contribute to infringement of the '703 patent.

The complaint, filed by an Indiana patent lawyer, lists two counts:

• Count I: Infringement of U.S. Patent No. 8,404,703
• Count II: Declaratory Judgment of Infringement of U.S. Patent No. 8,404,703

Plaintiffs ask the court for judgment:

• That HEC Pharm has infringed the '703 patent and/or will infringe, actively induce infringement of, and/or contribute to infringement by others of one or more claims of the '703 patent;
• That, pursuant to 35 U.S.C. § 271(e)(4)(B), HEC Pharm be permanently enjoined from making, using, selling or offering to sell any of its accused products within the United States, or, where applicable, importing accused products into the United States prior to the expiration of the '703 patent;
• That, pursuant to 35 U.S.C. § 271(e)(4)(A), the effective date of any approval of the HEC Pharm ANDA under § 505(j) of the Federal Food, Drug and Cosmetic Act (21 U.S.C. § 355(j)) shall not be earlier than the later of the expiration dates of the '703 patent, including any extensions;
• If HEC Pharm commercially makes, uses, sells or offers to sell any accused product within the United States, or, where applicable, imports any accused product into the United States, prior to the expiration of either of the '703 patent, including any extensions, that Plaintiffs be awarded monetary damages for those infringing acts to the fullest extent allowed by law and be awarded prejudgment interest based on those monetary damages;
• That the case be deemed exceptional under 35 U.S.C. § 285;
• That the '703 patent remains valid and enforceable;
• That Plaintiffs be awarded reasonable attorney's fees, costs and expenses.

Practice Tip #1: The Effient litigation also involves Patent No. 5,288,726, "Tetrahydrothienopyridine Derivatives, Furo and Pyrrolo Analogs Thereof and Their Preparation and Uses for Inhibiting Blood Platelet Aggregation," and Patent No. 8,569,325, "Method of Treatment with Coadministration of Aspirin and Prasugrel."

Practice Tip #2: The FDA's ANDA process for generic drugs has been abbreviated such that, in general, the generic drug seeking approval does not require pre-clinical (animal and in vitro) testing. Instead, the process focuses on establishing that the product is bioequivalent to the "innovator" drug that has already undergone the full approval process.

The statute that created the abbreviated process, however, had also created some interesting jurisdictional issues with respect to declaratory judgments. For an interesting look at some of the issues, see here

Indiana Patent Litigation - Lilly Adds Panacea Biotec to List of Patent Infringement Defendants

Indianapolis, Indiana - An Indiana patent attorney for Eli Lilly and Company of Indianapolis, Indiana; Daiichi Sankyo Co., Ltd of Tokyo, Japan; Daiichi Sankyo, Inc. of Parsippany, NewEffient-pill.jpg Jersey; and Ube Industries, Ltd. of Yamaguchi, Japan sued in the Southern District of Indiana alleging that Panacea Biotec, Ltd. of New Delhi, India ("Panacea") infringed Effient® products, Patent Nos. 8,404,703 and 8,569,325, which have been issued by the United States Patent Office.

This lawsuit adds another defendant, Panacea, to Lilly's Indiana patent litigation. In these "Effient" patent-defense lawsuits, Lilly et al. assert allegations of infringement of Effient. At issue in the Panacea litigation are Effient-related patents 8,404,703 "Medicinal Compositions Containing Aspirin," (the "'703 patent") and 8,569,325 "Method of Treatment with Coadministration of Aspirin and Prasugrel" (the "'325 patent").

This complaint asserts patent infringement arising out of the filing by Panacea of an Abbreviated New Drug Applications ("ANDA") with the United States Food and Drug Administration ("FDA") seeking approval to manufacture and sell generic versions of two pharmaceutical products - Effient 5mg and Effient 10mg tablets - prior to the expiration of the '703 patent and the '325 patent. These patents cover two Effient products and/or methods of using Effient products and for which Lilly claims an exclusively license.

Effient products were approved by the FDA for the reduction of thrombotic cardiovascular events in certain patients with acute coronary syndrome (ACS) who are to be managed with percutaneous coronary intervention (PCI, or angioplasty). Effient products contain prasugrel hydrochloride, which is also known as 5-[(1RS)-2-cyclopropyl-1-(2-fluorophenyl)-2-oxoethyl]-4,5,6,7-tetrahydrothieno[3,2-c]pyridin-2-yl acetate hydrochloride or 2-acetoxy-5-(alpha-cyclopropylcarbonyl-2-fluorobenzy1)-4,5,6,7-tetrahydrothieno[3,2-c]pyridine hydrochloride, and is covered by the '726 patent.

The instructions accompanying Effient products state that patients taking Effient products should also take aspirin. The use of Effient products in combination with aspirin for the reduction of thrombotic cardiovascular events in patients with ACS who are to be managed with PCI is allegedly covered by the claims of the '703 and '325 patents.

Panacea is accused of planning to infringe the patents-in-suit by including with its products instructions for use that substantially copy the instructions for Effient products, including instructions for administering Panacea's products with aspirin as claimed in the '703 and '325 patents.

Plaintiffs contend that Panacea knows that the instructions that Panacea intends to include with its products will induce and/or contribute to others using those products in the allegedly infringing manner set forth in the instructions. Moreover, Lilly et al. also contend that Panacea specifically intends for health care providers, and/or patients to use Panacea's products in accordance with the instructions provided by Panacea and that such use will directly infringe one or more claims of the '703 and '325 patents. Thus, state Plaintiffs, Panacea's actions will actively induce and/or contribute to infringement of the '703 and '325 patents.

The complaint, filed by an Indiana patent lawyer, lists four counts:

• Count I: Infringement of U.S. Patent No. 8,404,703
• Count II: Declaratory Judgment of Infringement of U.S. Patent No. 8,404,703
• Count III: Infringement of U.S. Patent No. 8,569,325
• Count IV: Declaratory Judgment of Infringement of U.S. Patent No. 8,569,325

Plaintiffs ask the court for judgment:

• That Panacea has infringed the '703 patent and/or will infringe, actively induce infringement of, and/or contribute to infringement by others of one or more claims of the '703 patent;
• That Panacea has infringed the '325 patent and/or will infringe, actively induce infringement of, and/or contribute to infringement by others of one or more claims of the '325 patent;
• That, pursuant to 35 U.S.C. § 271(e)(4)(B), Panacea be permanently enjoined from making, using, selling or offering to sell any of its accused products within the United States, or, where applicable, importing accused products into the United States prior to the expiration of the '703 and '325 patents;
• That, pursuant to 35 U.S.C. § 271(e)(4)(A), the effective date of any approval of the Panacea ANDA under § 505(j) of the Federal Food, Drug and Cosmetic Act (21 U.S.C. § 355(j)) shall not be earlier than the later of the expiration dates of the '703 and '325 patents, including any extensions;
• If Panacea commercially makes, uses, sells or offers to sell any accused product within the United States, or, where applicable, imports any accused product into the United States, prior to the expiration of either of the '703 and '325 patents, including any extensions, that Plaintiffs be awarded monetary damages for those infringing acts to the fullest extent allowed by law and be awarded prejudgment interest based on those monetary damages;
• That the case be deemed exceptional under 35 U.S.C. § 285;
• That the '703 patent remains valid and enforceable;
• That the '325 patent remains valid and enforceable; and
• That Plaintiffs be awarded reasonable attorney's fees, costs and expenses.

Practice Tip: In March 2014, Lilly et al. filed a 101-page complaint making similar accusations against more than thirty defendants: Accord Healthcare, Inc. USA; Accord Healthcare, Inc.; Intas Pharmaceuticals Ltd.; Amneal Pharmaceuticals LLC; Amneal Pharmaceuticals of New York, LLC; Amneal Pharmaceuticals Co. India Pvt.

Indiana Patent Infringement Litigation: Eli Lilly Sues Numerous Defendants

Indianapolis, Indiana - An Indiana patent attorney for Eli Lilly and Company of Indianapolis, Indiana ("Lilly") filed a lawsuit in the Southern District of Indiana against multiple defendants asserting infringement of Patent Nos. 5,288,726, "Tetrahydrothienopyridine Derivatives, Furo and Pyrrolo Analogs Thereof and Their Preparation and Uses for Inhibiting Blood Platelet Effient-picture.jpgAggregation," 8,569,325, "Method of Treatment with Coadministration of Aspirin and Prasugrel" and 8,404,703, "Medicinal Compositions Containing Aspirin," which have been issued by the U.S. Patent Office.

In a 101-page complaint, Indiana patent counsel for Plaintiffs Lilly; Daiichi Sankyo Co., Ltd.; Daiichi Sankyo, Inc.; and Ube Industries, Ltd. sued alleging patent infringement by more than thirty Defendants. The Defendants are:  Accord Healthcare, Inc. USA; Accord Healthcare, Inc.; Intas Pharmaceuticals Ltd.; Amneal Pharmaceuticals LLC; Amneal Pharmaceuticals of New York, LLC; Amneal Pharmaceuticals Co. India Pvt. Ltd.; Aurobindo Pharma Limited; Aurobindo Pharma USA Inc.; Dr. Reddy's Laboratories, Ltd; Dr. Reddy's Laboratories, Inc.; Glenmark Generics Inc., USA; Glenmark Generics Ltd.; Glenmark Pharmaceuticals Ltd.; Hetero USA Inc.; Hetero Labs Limited; Hetero Labs Limited Unit V; Hetero Drugs Ltd.; Mylan Pharmaceuticals Inc.; Mylan Inc.; Mylan Laboratories Limited (these three companies are, collectively, "Mylan"); Par Pharmaceutical Companies, Inc.; Par Pharmaceutical, Inc.; Sun Pharma Global FZE; Caraco Pharmaceutical Laboratories, Ltd.; Sun Pharma Global Inc.; Sun Pharmaceutical Industries, Ltd.; Teva Pharmaceuticals USA, Inc.; Teva Pharmaceutical Industries, Ltd.; Watson Laboratories, Inc.; Actavis plc; Actavis, Inc.; Actavis Pharma, Inc.; Zydus Pharmaceuticals USA, Inc.; and Cadila Healthcare Ltd. (d/b/a Zydus Cadila). Defendants hail from various areas of the world, including India, the United Arab Emirates, the British Virgin Islands, Israel, Ireland and the United States.

This complaint asserts patent infringement arising out of the filing by Defendants of Abbreviated New Drug Applications ("ANDA"s) with the United States Food and Drug Administration ("FDA") seeking approval to manufacture and sell generic versions of two pharmaceutical products - Effient® 5mg and Effient® 10mg tablets (pictured above) - prior to the expiration of United States Patent Nos. 5,288,726 (the "'726 patent"), 8,404,703 (the "'703 patent") and 8,569,325 (the "'325 patent"), which cover the two Effient® products and/or methods of using Effient® products and for which Lilly claims an exclusively license.

Effient® products were approved by the FDA for the reduction of thrombotic cardiovascular events in certain patients with acute coronary syndrome (ACS) who are to be managed with percutaneous coronary intervention (PCI, or angioplasty). Effient® products contain prasugrel hydrochloride, which is also known as 5-[(1RS)-2-cyclopropyl-1-(2-fluorophenyl)-2-oxoethyl]-4,5,6,7-tetrahydrothieno[3,2-c]pyridin-2-yl acetate hydrochloride or 2-acetoxy-5-(alpha-cyclopropylcarbonyl-2-fluorobenzy1)-4,5,6,7-tetrahydrothieno[3,2-c]pyridine hydrochloride, and is covered by the '726 patent.

The instructions accompanying Effient® products state that patients taking Effient® products should also take aspirin. The use of Effient® products in combination with aspirin for the reduction of thrombotic cardiovascular events in patients with ACS who are to be managed with PCI is allegedly covered by the claims of the '703 and '325 patents.

Defendants are, in general, accused of infringing the patents-in-suit by including with their products instructions for use that substantially copy the instructions for Effient® products, including instructions for administering the Defendants' products with aspirin as claimed in the '703 and '325 patents. Moreover, Plaintiffs contend that Defendants know that the instructions that will accompany the Defendants' Products will induce and/or contribute to others using the Defendants' Products in the manner set forth in the instructions.

Plaintiffs also contend that Defendants specifically intend that health care providers, and/or patients will use the Defendants' Products in accordance with the instructions provided by Defendants to directly infringe one or more claims of the '703 and '325 patents. In doing so, state Plaintiffs, Defendants will actively induce and/or contribute to infringement of the '703 and '325 patents.

The complaint, filed by an Indiana patent attorney, lists a total of fifty counts. All Defendants are accused of infringement of the '703 and '325 patents. Declaratory judgment of infringement of these patents is sought against all Defendants. Additionally, claims of infringement of, and a request for declaratory judgment regarding, the '726 patent are made against Mylan.

Plaintiffs ask the court for judgment:

• That all Defendants, either individually or collectively, have infringed or will infringe one or more claims of the '703 patent;
• That all Defendants, either individually or collectively, have infringed or will infringe one or more claims of the '325 patent;
• That Mylan, either individually or collectively, has infringed or will infringe one or more claims of the '726 patent;
• That, pursuant to 35 U.S.C. § 271(e)(4)(B), Defendants be permanently enjoined from making, using, selling or offering to sell any of the Defendants' accused products within the United States, or, where applicable, importing accused products into the United States prior to the expiration of the '703 and '325 patents;
• That, pursuant to 35 U.S.C. § 271(e)(4)(A), the effective date of any approval of any ANDAs under § 505(j) of the Federal Food, Drug and Cosmetic Act (21 U.S.C. § 355(j)) shall not be earlier than the later of the expiration dates of the '703 and '325 patents, including any extensions;
• That the '703 patent remains valid and enforceable;
• That the '325 patent remains valid and enforceable;
• That the '726 patent remains valid and enforceable;
• If any Defendant commercially makes, uses, sells or offers to sell any accused product within the United States, or, where applicable, imports any accused product into the United States, prior to the expiration of either of the '703 and '325 patents, including any extensions, that Plaintiffs be awarded monetary damages for those infringing acts to the fullest extent allowed by law and be awarded prejudgment interest based on those monetary damages;
• If Mylan commercially makes, uses, sells or offers to sell any accused product within the United States, or, where applicable, imports any accused product into the United States, prior to the expiration of the '726 patent, including any extensions, that Plaintiffs be awarded monetary damages for those infringing acts to the fullest extent allowed by law and be awarded prejudgment interest based on those monetary damages;
• That the case be deemed exceptional under 35 U.S.C. § 285; and
• That Plaintiffs be awarded reasonable attorney's fees, costs and expenses.

Practice Tip: Lilly is not an infrequent litigant. This may be in part due to the fact that the company is facing a significant patent cliff. Its patent for a former top product, the antipsychotic Zyprexa - which once generated $5 billion in annual revenues - expired in 2011. Its top-selling drug of 2013, the antidepressant Cymbalta, lost patent protection last year. The patent on blockbuster Evista, a drug for breast cancer and osteoporosis, expires this month.

Alcon Sues Cipla for Patent Infringement of Pataday™

Indianapolis, Indiana - Indiana patent lawyers for Alcon Research, LTD of Fort Worth,pataday.jpg Texas and Alcon Pharmaceuticals Ltd of Fribourg, Switzerland (collectively, "Alcon") sued in the Southern District of Indiana alleging that Cipla Limited of Mumbai Central, Mumbai and Cipla USA Inc. of Miami, Florida (collectively, "Cipla") infringed Olopatadine Formulations for Topical Administration, Patent Nos. 6,995,186 (the "'186 patent") and 7,402,609 (the "'609 patent"), which have been issued by the U.S. Patent Office.

According to the complaint, the Cipla entities are engaged in the generic-pharmaceutical business. Alcon asserts that one or more of the entities develops, manufactures, imports, markets, offers to sell and/or sells generic drugs throughout the United States.

Cipla filed an Abbreviated New Drug Application ("ANDA") with the U.S. Food and Drug Administration ("FDA") seeking approval to manufacture and sell a generic version of Pataday™ ophthalmic solution, a drug product containing olopatadine hydrochloride. The two patents-in-suit, which Alcon claims to own, are asserted to cover Pataday™. Alcon contends that Cipla's submission of this ANDA to obtain approval to engage in the commercial manufacture, use, offer for sale, sale and/or importation of Cipla's ANDA product before the expiration of the patents-in-suit is an act of infringement under 35 U.S.C. § 271(e)(2)(A).

Alcon states that it believes that the Cipla entities are part of a vertically integrated and unified organization and that they will act in concert to introduce the generic version of Pataday™ to the United States market prior to the expiration of Alcon's patents.

In the complaint, intellectual property attorneys for Alcon list the following claims:

• Count I: Infringement of the '186 Patent
• Count II: Infringement of the '609 Patent
• Count III: Declaratory Judgment of Infringement of the '186 Patent
• Count IV: Declaratory Judgment of Infringement of the '609 Patent

Alcon asks for a judgment that the '186 and '609 patents are valid and enforceable and have been infringed; a judgment providing that the effective date of any FDA approval of commercial manufacture, use or sale of Cipla's ANDA product be not earlier than the latest of the expiration date of the patents-in-suit, inclusive of any extension(s) and additional periods of exclusivity; preliminary and permanent injunctions protecting products covered by the '186 patent prior to its expiration; preliminary and permanent injunctions protecting products covered by the '609 patent prior to its expiration; a judgment declaring that the commercial manufacture, use, sale, offer for sale or importation of Cipla's ANDA product, or any other drug product covered by the '186 patent, will infringe, induce the infringement of, and contribute to the infringement by others of, that patent; a judgment declaring that the commercial manufacture, use, sale, offer for sale or importation of Cipla's ANDA product, or any other drug product covered by the '609 patent, will infringe, induce the infringement of, and contribute to the infringement by others of, that patent; a declaration that this is an exceptional case and an award of attorneys' fees; and costs and expenses.

Practice Tip:

India is the world's leading exporter of generic drugs. Some Indian manufacturers are aggressively seeking to have their generic versions approved by the FDA well before a brand-name drug's patent(s) expire. This has led to a substantial amount of patent litigation against Indian companies, as the difference in market price between brand-name drugs and their generic counterparts can be enormous.

In addition to Indian companies being subject to litigation in the United States, Indian courts are also actively engaged in the ongoing dispute over intellectual property rights. Those courts, as well as the Indian government, have in several notable instances found in favor of Indian generic-drug manufacturers and against intellectual property holders in the United States. For example, in 2012, a decision by India's Controller General of Patents, Designs and Trademarks granted a "compulsory license" of the patented cancer drug Nexavar.

According to this decision, Bayer must license Nexavar to Natco Pharma, an Indian company, in exchange for a 6% royalty on Natco's net sales. The generic drug will be sold in India for $176 per month instead of the $5,600 per month that Bayer had been charging in that market.

While a provision exists within the World Trade Organization's Trade-Related Aspects of Intellectual Property Rights ("TRIPS") Agreement that allows for compulsory licensing of pharmaceuticals, it has been used only infrequently, usually for drugs that treat AIDS. This was the first time such compulsory licensing was granted in India. India is only the second country, after Thailand, to grant a compulsory license to a cancer drug.

Lilly Sues Glenmark Generics for Over Proposed Manufacture and Sale of Generic Version of ALIMTA®

Indianapolis, Indiana - Indiana patent attorneys for Eli Lilly and Company of Indianapolis,Alimta.bmp Indiana ("Lilly") filed a lawsuit in the Southern District of Indiana alleging that Glenmark Generics, Inc., USA of Mahwah, New Jersey ("Glenmark") infringed Antifolate Combination Therapies, Patent No. 7,772,209, which has been issued by the U.S. Patent Office.

Lilly is engaged in the business of research, development, manufacture and sale of pharmaceutical products worldwide. Glenmark is in the business of distributing, selling, and offering to sell drug products throughout the United States.

ALIMTA®, which is allegedly licensed to Lilly, is a chemotherapy agent used for the treatment of various types of cancer. ALIMTA® is composed of the pharmaceutical chemical pemetrexed disodium. It is indicated, in combination with cisplatin, (a) for the treatment of patients with malignant pleural mesothelioma, or (b) for the initial treatment of locally advanced or metastatic nonsquamous non-small cell lung cancer. ALIMTA® also is indicated as a single agent for the treatment of patients with locally advanced or metastatic nonsquamous non-small cell lung cancer after prior chemotherapy. Additionally, ALIMTA® is indicated for maintenance treatment of patients with locally advanced or metastatic nonsquamous non-small cell lung cancer whose disease has not progressed after four cycles of platinum-based first-line chemotherapy. One or more claims of U.S. Patent No. 7,772,209 ("the '209 patent") cover a method of administering pemetrexed disodium to a patient in need thereof that also involves administration of folic acid and vitamin B12.

This Indiana patent infringement lawsuit arises out of the filing by Defendant Glenmark of an Abbreviated New Drug Application ("ANDA") with the U.S. Food and Drug Administration ("FDA") seeking approval to manufacture and sell generic versions of ALIMTA® prior to the expiration of the '209 patent. Glenmark filed as a part of ANDA No. 205526 a certification of the type described in Section 505(j)(2)(A)(vii)(IV) of the Food, Drug and Cosmetic Act, 21 U.S.C. § 55(j)(2)(A)(vii)(IV), with respect to the '209 patent, asserting that the claims of the '209 patent are invalid, unenforceable, and/or not infringed by the manufacture, use, offer for sale, or sale of Glenmark's ANDA products.

In its complaint, filed by an Indiana patent lawyer, Lilly states that Glenmark intends to engage in the manufacture, use, offer for sale, sale, marketing, distribution, and/or importation of Glenmark's ANDA Products and the proposed labeling therefor immediately and imminently upon approval of ANDA No. 205526, i.e., prior to the expiration of the '209 patent. Lilly asserts that Glenmark's actions constitute and/or will constitute infringement of the '209 patent, active inducement of infringement of the '209 patent, and contribution to the infringement by others of the '209 patent.

Lilly asks for:

• A judgment that Glenmark has infringed the '209 patent and/or will infringe, actively induce infringement of, and/or contribute to infringement by others of the '209 patent;
• A judgment ordering that the effective date of any FDA approval for Glenmark to make, use, offer for sale, sell, market, distribute, or import Glenmark's ANDA Products, or any product the use of which infringes the '209 patent, be not earlier than the expiration date of the '209 patent, inclusive of any extension(s) and additional period(s) of exclusivity;
• A preliminary and permanent injunction enjoining Glenmark, and all persons acting in concert with Glenmark, from making, using, selling, offering for sale, marketing, distributing, or importing Glenmark's ANDA Products, or any product the use of which infringes the '209 patent, or the inducement of or contribution to any of the foregoing, prior to the expiration date of the '209 patent, inclusive of any extension(s) and additional period(s) of exclusivity;
• A judgment declaring that making, using, selling, offering for sale, marketing, distributing, or importing of Glenmark's ANDA Products, or any product the use of which infringes the '209 patent, prior to the expiration date of the '209 patent, infringes, will infringe, will actively induce infringement of, and/or will contribute to the infringement by others of the '209 patent;
• A declaration that this is an exceptional case and an award of attorneys' fees pursuant to 35 U.S.C. § 285; and
• An award of Lilly's costs and expenses in this action.

Practice Tip: The FDA's ANDA process for generic drugs has been abbreviated such that, in general, the generic drug seeking approval does not require pre-clinical (animal and in vitro) testing. Instead, the process focuses on establishing that the product is bioequivalent to the "innovator" drug that has already undergone the full approval process. The statute that created the abbreviated process, however, had also created some interesting issues with respect to the period of exclusivity. For a look at some of these issues, see here.

Eli Lilly Sues Par Pharmaceutical Asserting Patent Infringement of Effient®

Indianapolis, Indiana - An Indiana patent attorney sued in the Southern District of Indiana on behalf of Eli Lilly and Company of Indianapolis, Indiana; Daiichi Sankyo Co., Ltd. of Tokyo, Japan ("Daiichi Sankyo"); Daiichi Sankyo, Inc. of Parsippany, New Jersey ("DSI"); and Ube Industries, Ltd. of Yamaguchi, Japan alleging that Par Pharmaceutical Companies, Inc. ("Par Pharmaceutical Companies") and Par Pharmaceutical, Inc. ("Par"), both of Woodcliff Lake, New Jersey, (collectively "Par Pharmaceutical") infringed Medicinal Compositions Containing Aspirin, Patent No. 8,404,703 (the "'703 patent") and Method of Treatment and Coadministration of Aspirin and Prasugrel, Patent No. 8,569,325 (the "'325 patent"), which have been issued by the U.S. Patent Office.

diagram.pngThis is a civil action for patent infringement. It arises out of the filing by Defendant Par of an Abbreviated New Drug Application ("ANDA") with the United States Food and Drug Administration ("FDA") seeking approval to manufacture and sell generic versions of two of Lilly's pharmaceutical products, Effient® 5mg and Effient® 10mg tablets, prior to the expiration of Daiichi Sankyo's and Ube's U.S. patents, which purportedly cover methods of using Effient® products. Lilly asserts that it holds an exclusive license to these products. DSI currently co-promotes Effient® products in the United States with Lilly.

Effient® products were approved by the FDA for the reduction of thrombotic cardiovascular events in certain patients with acute coronary syndrome (ACS) who are to be managed with percutaneous coronary intervention (PCI, or angioplasty). The instructions accompanying Effient® products state that patients taking Effient® products should also take aspirin. The use of Effient® products in combination with aspirin for the reduction of thrombotic cardiovascular events in patients with ACS who are to be managed with PCI is covered by the claims of the '703 and '325 patents.

Par has submitted an Abbreviated New Drug Application (the "Par ANDA") to the FDA pursuant to 21 U.S.C. § 355(j), seeking approval to market a generic version of Lilly's product for oral administration (the "Par Products") in the United States.

Plaintiffs assert that Par will knowingly include with the Par Products instructions for use that substantially copy the instructions for Effient® products, including instructions for administering the Par Products with aspirin as claimed in the '703 and '325 patents. Moreover, Plaintiffs contend that Par knows that the instructions that will accompany the Par Products will induce and/or contribute to others using the Par Products in the manner set forth in the instructions. Plaintiffs also contend that Par specifically intends that health care providers, and/or patients will use the Par Products in accordance with the instructions provided by Par to directly infringe one or more claims of the '703 and '325 patents. Par therefore will actively induce and/or contribute to infringement of the '703 and '325 patents, state Plaintiffs.

In the complaint, the Indiana patent lawyer for Plaintiffs listed the following counts:

• Count I: Infringement of U.S. Patent No. 8,404,703
• Count II: Declaratory Judgment of Infringement of U.S. Patent No. 8,404,703
• Count III: Infringement of U.S. Patent No. 8,569,325
• Count IV: Declaratory Judgment of Infringement of U.S. Patent No. 8,569,325

Plaintiffs ask the court for judgment:

A. That Defendants, either individually or collectively, have infringed or will infringe, after the Par ANDA is approved, one or more claims of the '703 patent;
B. That Defendants, either individually or collectively, have infringed or will infringe, after the Par ANDA is approved, one or more claims of the '325 patent;
C. That, pursuant to 35 U.S.C. § 271(e)(4)(B), Par and Par Pharmaceutical Companies be permanently enjoined from making, using, selling or offering to sell either or both of the Par Products within the United States, or importing either or both of the Par Products into the United States prior to the expiration of the '703 and '325 patents;
D. That, pursuant to 35 U.S.C. § 271(e)(4)(A), the effective date of any approval of the Par ANDA under § 505(j) of the Federal Food, Drug and Cosmetic Act (21 U.S.C. § 355(j)) shall not be earlier than the latest of the expiration dates of the '703 and '325 patents, including any extensions;
E. A judgment declaring that the '703 patent remains valid and enforceable;
F. A judgment declaring that the '325 patent remains valid and enforceable;
G. If either Par or Par Pharmaceutical Companies commercially makes, uses, sells or offers to sell either or both of the Par Products within the United States, or imports either or both of the Par Products into the United States, prior to the expiration of either of the '703 and '325 patents, including any extensions, that Plaintiffs will be awarded monetary damages for those infringing acts to the fullest extent allowed by law and be awarded prejudgment interest based on those monetary damages;
H. That this case be deemed exceptional under 35 U.S.C. § 285; and
I. That Plaintiffs be awarded reasonable attorney's fees, costs and expenses.

Practice Tip: Lilly is not an infrequent litigant. This may be in part due to the fact that the company is facing a significant patent cliff. Its patent for a former top product, the antipsychotic Zyprexa - which once generated $5 billion in annual revenues - expired in 2011.

Eli Lilly Sues Actavis for Infringement of Patents Related to Axiron

Indianapolis, Indiana - Eli Lilly and Company of Indianapolis, Indiana; Eli Lilly Export S.A. of Geneva, Switzerland (collectively, "Lilly"); and Acrux DDS Pty Ltd. of West Melbourne, Australia have filed a patent infringement lawsuit in the Southern District of Indiana alleging that Actavis, Inc. and Actavis Pharma, Inc., both of Parsippany, New Jersey, and Watson Laboratories, Inc. of Corona, California infringed Patent Nos. 6,299,900 - Dermal Penetration Enhancers and Drug Delivery Systems Involving Same; 6,818,226 - Dermal Penetration Enhancers and Drug Delivery Systems Involving Same; 6,923,983 - Transdermal Delivery of Hormones; 8,071,075 - Dermal Penetration Enhancers and Drug Delivery Systems Involving Same; 8,419,307 - Spreading Implement; and 8,435,944 - Method and Composition for Transdermal Drug Delivery (collectively, the "patents-in-suit") which have been issued by the U.S. Patent Office.

Lilly is engaged in the business of research, development, manufacture and sale of Thumbnail image for Thumbnail image for Thumbnail image for Lilly-logo.pngpharmaceutical products. Acrux is engaged in the development and commercialization of pharmaceutical products. Both sell their products worldwide.

Actavis, Inc., along with its wholly owned subsidiaries Actavis Pharma and Watson Laboratories, (collectively, "Actavis") are pharmaceutical companies that develop, manufacture, market and distribute generic pharmaceutical products for sale in the United States.

Lilly is the holder of approved New Drug Application No. 022504 for the manufacture and sale of a transdermal testosterone solution made at a concentration of 30 mg/1.5L, which it markets under the trade name "Axiron®." This drug is used to treat males for conditions associated with a deficiency or absence of endogenous testosterone.

This action relates to the Abbreviated New Drug Application ("ANDA") No. 205328 submitted by Watson Laboratories to the U.S. Food and Drug Administration ("FDA") for approval to market a generic version of Lilly's Axiron product. Defendants certified to the FDA that, in their opinion, the patents-in-suit were invalid, unenforceable and/or would not be infringed by the commercial manufacture, use or sale of the generic version of Axiron described in the ANDA.

As part of its ANDA filing, Defendants sent to Lilly and Acrux an "Offer of Confidential Access" which would allow limited access to Actavis' ANDA. Lilly and Acrux were unsatisfied with the offer, stating that the restrictions it contained would prohibit crucial decision makers from having access to the ANDA. Lilly and Acrux also contended that the restrictions were improper as they were not directed to the purpose of protecting trade secrets and other confidential business information. While attempts to reach an agreement regarding access to the ANDA were made, they were not successful.

Plaintiffs contend that the submission of the ANDA to the FDA constitutes infringement by Defendants of the patents-in-suit. In their complaint, patent lawyers for Lilly and Acrux assert twenty-four separate counts related to patent infringement. For each of the patents-in-suit, there is one count of "Direct Infringement," one count of "Inducement to Infringe," one count of "Contributory Infringement" and one count for declaratory judgment.

The complaint asks for an injunction to stop Defendants from producing the generic version of Axiron until the expiration of Lilly's patents-in-suit. In addition, Lilly asks that the court declare the patents to be valid and enforceable; that Defendants infringed upon all of the patents-in-suit by, inter alia, submitting ANDA No. 205328 to obtain approval to commercially manufacture, use, offer for sale, sell or import its generic version of the drug into the United States; that Defendants' threatened acts constitute infringement of the patents-in-suit; that FDA approval of Defendants' generic drug be effective no sooner than the expiration date of the patent that expires last; and that this is an exceptional case. Plaintiffs also ask for costs and attorneys' fees.

Practice Tip #1: The FDA's ANDA process for generic drugs has been abbreviated such that, in general, the generic drug seeking approval does not require pre-clinical (animal and in vitro) testing. Instead, the process focuses on establishing that the product is bioequivalent to the "innovator" drug that has already undergone the full approval process. The statute that created the abbreviated process, however, had also created some interesting issues with respect to the period of exclusivity. For a look at some of these issues, see here.

Practice Tip #2: An offer of confidential access to an ANDA "shall contain such restrictions as to persons entitled to access, and on the use and disposition of any information accessed, as would apply had a protective order been entered for the purpose of protecting trade secrets and other confidential business information." 21 USC § 355(c)(3)(D)(i).

Alcon Sues Wockhardt for Patent Infringement of Pataday™

Indianapolis, Indiana -- Alcon Research, Ltd. of Fort Worth, Texas, and Alcon Pharmaceuticals Ltd. of Fribourg, Switzerland (collectively, "Alcon") have filed a patent infringement lawsuit in the Southern District of Indiana alleging that Wockhardt Limited of Mumbai, Maharashta, India; Wockhardt Bio AG of Zug, Switzerland; Wockhardt Bio Ltd. of Zug, Switzerland; and Wockhardt USA, LLC of Parsippany, New Jersey (collectively, "Wockhardt") infringed Patent Nos. 6,995,186 (the "'186 patent") and 7,402,609 (the "'609 patent"), both for Olopatadine Formulations For Topical Administration, which have been issued by the U.S. Patent Office. 

According to the complaint, the Wockhardt entities are engaged in the generic-pharmaceutical business.  Alcon asserts that one or more of the entities manufacture, import, market, offer to sell and/or sell generic drugs throughout the United States. 

Wockhardt filed an Abbreviated New Drug Application ("ANDA") with the U.S. Food and Drug Administration ("FDA") seeking approval to manufacture and sell a generic version of Pataday™ ophthalmic solution, a drug product containing olopatadine hydrochloride.  The two patents-in-suit, which Alcon claims to own, are asserted to cover Pataday™.  Alcon contends that Wockhardt's submission of this ANDA to obtain approval to engage in the commercial manufacture, use, offer for sale, sale and/or importation of Wockhardt's ANDA product before the expiration of the patents-in-suit is an act of infringement under 35 U.S.C. § 271(e)(2)(A).

Plaintiff Alcon states that it believes that the Wockhardt entities are part of a vertically integrated and unified organization and that they will act in concert to introduce the generic version of Pataday™ to the United States market prior to the expiration of Alcon's patents. 

In the complaint, intellectual property attorneys for Alcon list the following claims:

·         Count I: Infringement of the '186 Patent

·         Count II: Infringement of the '609 Patent

·         Count III: Declaratory Judgment of Infringement of the '186 Patent

·         Count IV: Declaratory Judgment of Infringement of the '609 Patent

Alcon asks for a judgment that the '186 and '609 patents are valid and enforceable and have been infringed; a judgment providing that the effective date of any FDA approval of commercial manufacture, use or sale of Wockhardt's ANDA product be not earlier than the latest of the expiration date of the patents-in-suit, inclusive of any extension(s) and additional periods of exclusivity; preliminary and permanent injunctions protecting products covered by the '186 patent prior to its expiration; preliminary and permanent injunctions protecting products covered by the '609 patent prior to its expiration; a judgment declaring that the commercial manufacture, use, sale, offer for sale or importation of Wockhardt's ANDA product, or any other drug product covered by the '186 patent, will infringe, induce the infringement of, and contribute to the infringement by others of, that patent; a judgment declaring that the commercial manufacture, use, sale, offer for sale or importation of Wockhardt's ANDA product, or any other drug product covered by the '609 patent, will infringe, induce the infringement of, and contribute to the infringement by others of, that patent; a declaration that this is an exceptional case and an award of attorneys' fees; and costs and expenses.

Practice Tip: The FDA's ANDA process for generic drugs has been abbreviated such that, in general, the generic drug seeking approval does not require pre-clinical (animal and in vitro) testing.  Instead, the process focuses on establishing that the product is bioequivalent to the "innovator" drug that has already undergone the full approval process.  The statute that created the abbreviated process, however, had also created some interesting issues with respect to the period of exclusivity.  For an interesting look at some of these issues, see here.

Eli Lilly Defending Method-of-Use Patent for Blockbuster Drug

Indianapolis, Indiana - Patent lawyers for Eli Lilly and Company ("Lilly") of Indianapolis, Indiana are in trial again this week in the Southern District of Indiana pursuing patent-infringement allegations against five generic-drug challengers, including AAP Pharmaceuticals of Schaumberg, Illinois and Pliva Hrvatksa of Croatia.  At issue is Lilly's patent on the use of Alimta in conjunction with specific vitamins; patents for the two Alimta treatments, both with and without the supplemental therapy, have been issued by the U.S. Patent Office. 

Lilly sells the drug Alimta to treat various types of lung cancer, Thumbnail image for logo.pngincluding mesothelioma.  However, certain side effects were troublesome, including treatment-related hematologic and gastrointestinal toxicity.  Deaths among some patients were attributed to treatment with Alimta.  In response to this concern, Lilly took the unusual step of mandating supplementation of the Alimta protocol with two vitamins, folic acid and vitamin B12.  The patentability of that idea is the focus of a patent challenge by five makers of generic drugs.

Patent-infringement litigation between brand-name manufacturers and generic-drug makers is common.  In a typical lawsuit, a company which wishes to sell a generic version of a brand-name drug, usually a widely used drug, will try to invalidate the patent on the drug, in the hopes that it could then offer the same drug in generic form.

This litigation is different from traditional patent litigation.  The original patent on Alimta, administered as a stand-alone treatment, protects only Alimta's active ingredient.  That patent will expire in 2017.  However, the focus of the current litigation is on the combination treatment which involves both Alimta and the vitamin regimen.  The patent on the method of administration, if upheld, would expire in 2022.

The generic challengers contend in part that the patent on the combined therapy is invalid, arguing that someone knowledgeable about both nutrition and medicine could have easily concluded that supplementation with B12 and folate might alleviate certain side effects of Alimta.

Lilly, in contrast, argues that the vitamin regimen was not only counterintuitive when it was proposed, it was called "crazy" a leading cancer doctor before testing showed its benefits.

The case, which is before Judge Tanya Walton Pratt, began last Monday and is expected to continue another week.

Practice Tip:

Lilly is facing a significant patent cliff.  Its patent for a former top product, the antipsychotic Zyprexa - which once generated $5 billion in annual revenues - expired in 2011.  Its current top-selling drug, the antidepressant Cymbalta, will lose patent protection this year.  The patent on blockbuster Evista, a breast cancer drug, will expire in early 2014. 

Alimta is currently Lilly's second-best-selling drug.  It generated $2.6 billion in sales last year, or about 11 percent of total Lilly's revenue.  Since it was launched in 2004, Alimta has generated $12 billion in total sales for Lilly through 2012.

Under patent law, a court can deem a patent invalid if its claims are "obvious" and anticipated by previous research.  In this case, the court will weigh the merits of the separate "method-of-use" patent on the administration of Alimta with B12 and folic acid.

If successful in defending this patent, intellectual-property law will grant market exclusivity to Lilly until 2022, allowing it to exclude generic manufacturers and, thus, to charge the higher brand-name price for Alimta therapy.  If the patent is not upheld in this litigation, Lilly will lose the five additional years of exclusivity that the second patent would have afforded.

Eli Lilly Sues Perrigo for Patent Infringement of Axiron

Indianapolis, Ind. -- Patent lawyers for Eli Lilly & Co. of Indianapolis, Ind. ("Lilly"), Eli Lilly Lilly2.JPGExport S.A., of Vernier/Geneva, Switzerland (a wholly owned subsidiary of Eli Lilly & Co.) and Acrux DDS Pty Ltd. of West Melbourne, Victoria, Australia ("Acrux") filed a patent infringement suit alleging that Perrigo Company of Allegan, Mich. ("Perrigo Company") and Perrigo Israel Pharmaceuticals Ltd. of Bnei Brak, Israel ("Perrigo Israel," a wholly owned subsidiary of Perrigo Company), infringed Patent Nos. 8,435,944; 8,419,307; and 8,177,449, filed with the U.S. Patent Office.

ACRUX-Logo.JPGLilly is engaged in the business of research, development, manufacture and sale of pharmaceutical products.  Acrux is engaged in the development and commercialization of pharmaceutical products for sale.  Both sell their products worldwide. 

Perrigo Company and Perrigo Israel (collectively, "Perrigo") are pharmaceutical companies that develop, manufacture, market and distribute generic pharmaceutical products for sale throughout the United States.  These products include pharmaceuticals, infant formulas, nutritional products, dietary supplements and active pharmaceutical ingredients.  Perrigo's consumer-healthcare segment includes over 2,100 store-brand products which are marketed to major national chains such as Wal-Mart, CVS, Walgreens, Sam's Club and Costco.  They also sell to major drug wholesalers.

Lilly is the holder of approved New Drug Application No. 022504 for the manufacture and sale of a transdermal testosterone solution made at a concentration of 30 mg/1.5L, which is marketed by Lilly under the trade name "Axiron."  Axiron is a pharmaceutical drug which raises the amount of testosterone in a patient's body.  Recent sales of Axiron are estimated to be $229 million annually, according to Symphony Health Solutions.  Axiron is subject to Patent Nos. 8,435,944, 8,419,307, 8,177,449 (the "'944 patent," the "'307 patent," and the "'449" patent, respectively).  All three patents have been licensed to Lilly.

Perrigo announced on May 29, 2013 that it had filed an Abbreviated New Drug Application ("ANDA") with the U.S. Food and Drug Administration ("FDA") for approval of a generic version of Axiron.  Prior to filing the ANDA, No. 204255, Perrigo sent a letter to Lilly to inform Lilly that "in Perrigo's opinion and to the best of its knowledge, the '449 patent is invalid, unenforceable, and/or will not be infringed by the commercial manufacture, use, sale, or importation of the drug product described in Perrigo's ANDA."  Perrigo sent similar letters regarding the '307 and '944 patents.

After receiving the letter, Lilly filed suit alleging infringement of the three patents.  It states in its complaint that the '944 patent claims, inter alia, methods of increasing the testosterone blood level of an adult male by applying a transdermal drug-delivery composition that contains testosterone.  The '307 patent includes in its claims a method of increasing the level of testosterone in the blood by applying a liquid pharmaceutical that contains testosterone.  The claims for the '449 patent include a method of transdermal administration of a physiologically active agent.  All three patents are used in connection with Axiron. 

Lilly's complaint lists the following claims:

·         Count I for Patent Infringement (Direct Infringement of U.S. Patent No. 8,435,944)

·         Count II for Patent Infringement (Inducement to Infringe U.S. Patent No. 8,435,944)

·         Count III for Patent Infringement (Contributory Infringement of U.S. Patent No. 8,435,944)

·         Count IV for Patent Infringement (Direct Infringement of U.S. Patent No. 8,419,307)

·         Count V for Patent Infringement (Inducement to Infringe U.S. Patent No. 8,419,307)

·         Count VI for Patent Infringement (Contributory Infringement of U.S. Patent No. 8,419,307)

·         Count VII for Patent Infringement (Direct Infringement of U.S. Patent No. 8,177,449)

·         Count VIII for Patent Infringement (Inducement to Infringe U.S. Patent No. 8,177,449)

·         Count IX for Patent Infringement (Contributory Infringement of U.S. Patent No. 8,177,449)

·         Count X for Declaratory Judgment (Infringement of U.S. Patent No. 8,435,944)

·         Count XI for Declaratory Judgment (Infringement of U.S. Patent No. 8,419,307)

·         Count XII for Declaratory Judgment (Infringement of U.S. Patent No. 8,177,449)

Lilly's lawsuit asks for an injunction to stop Perrigo from producing the generic version of Axiron until the expiration of Lilly's three patents-in-suit.  In addition, Lilly asks that the court declare the three patents to be valid and enforceable; that Perrigo infringed upon all three by, inter alia, submitting ANDA No. 204255 to obtain approval to commercially manufacture, use, offer for sale, sell or import its generic version of the drug into the United States; that Perrigo's threatened acts constitute infringement of the three patents; that FDA approval of Perrigo's generic drug be effective no sooner than the expiration date of the patent that expires last; that this is an exceptional case; and for costs and attorneys' fees.

Practice Tip: The FDA's ANDA process for generic drugs has been abbreviated such that, in general, the generic drug seeking approval does not require pre-clinical (animal and in vitro) testing.  Instead, the process focuses on establishing that the product is bioequivalent to the "innovator" drug that has already undergone the full approval process.  The statute that created the abbreviated process, however, had also created some interesting issues with respect to the period of exclusivity.  For an interesting look at some of these issues, see here.

Eli Lilly Sues Accord Healthcare Again for Infringement of Patented ALIMTA

Indianapolis, IN - Eli Lilly and Company of Indianapolis, Indiana filed an additional patent infringement suit in the Southern District of Indiana alleging Thumbnail image for Lilly2.JPGthat Accord Healthcare, Inc., USA of Durham, North Carolina will infringe U.S. Patent No. 7,772,209 (the "'209 patent") which has been issued by the U.S. Patent Office if relief is not afforded by the court. 

In a complaint that was almost identical to a previous complaint filed in January 2012, patent attorneys for Eli Lilly and Company ("Lilly") initiated an additional lawsuit against Accord Healthcare, Inc., USA ("Accord") for attempting to gain FDA approval to manufacture and sell a generic version of Lilly's ALIMTA, a drug that is used in the treatment in certain types of lung cancer.  ALIMTA is protected by the '209 patent. 

This is the second suit by Lilly against Accord involving the '209 patent.  This suit was initiated after Accord filed an Abbreviated New Drug Application ("ANDA") with the FDA for a product that competes with Lilly's ALIMTA, which is an "Antifolate Combination Therapies" product.  The complaint from 2012 alleged intent to infringe by, among other activities, the production and sale of Accord's "Pemetrexed Disodium for Injection," Thumbnail image for Accord.JPGa generic version of ALIMTA, in 100 mg/vial and 500 mg/vial products.  The current complaint alleged intent to infringe with a "Pemetrexed Disodium for Injection" product in a 1000 mg/vial strength.  As part of its ANDA filing, Accord alleged that the claims of the '209 patent are invalid and/or not infringed by Accord's product. 

Eli Lilly has sued alleging infringement of the patented ALIMTA before: 

·         Eli Lilly Sues Apotex Inc. for Patent Infringement of ALIMTA

·         Eli Lilly and Company Sues Accord Healthcare for Patent Infringement of Lung Cancer Drug ALIMTA

·         Lilly Wins Patent Infringement Suit Regarding Chemotherapy Drug

·         Eli Lilly Company Sues APP Pharmaceuticals LLC for Patent Infringement of Chemotherapy Drug

Lilly seeks a judgment that Accord has infringed and/or will infringe, actively induce infringement of, and/or contribute to infringement by others of the '209 patent; a judgment ordering that Accord delay virtually all activities pertaining to its ANDA product until after the '209 patent has expired; a preliminary and permanent injunction against activity that infringes upon the '209 patent; a declaratory judgment of infringement; a declaration that the case is exceptional and an award of attorneys' fees pursuant to such a declaration; and Lilly's costs and expenses. 

Practice Tip #1: The FDA's ANDA process for generic drugs has been abbreviated such that, in general, the generic drug seeking approval does not require pre-clinical (animal and in vitro) testing.  Instead, the process focuses on establishing that the product is bioequivalent to the "innovator" drug that has already undergone the full approval process.  The statute that created the abbreviated process, however, had also created some interesting jurisdictional issues with respect to declaratory judgments.  For an interesting look at some of the issues, see here.
