Indiana patent attorneys for CeraMedic LLC of Plano, Texas sued in the Northern District of Indiana alleging that DePuy Orthopaedics, Inc. of Warsaw, Indiana (“DePuy”) infringed “Sintered AL₂O₃ Material, Process for Its Production and Use of the Material,” Patent No. 6,066,584 (the “‘584 patent”), which has been issued by the U.S. Patent Office.

The ‘584 patent relates to the field of ceramics and concerns sintered Al₂O₃ compositions and methods for the use of such material as medical implants or tool material. It was issued in May 2000 to Fraunhofer-Gesellschaft zur Förderung der Angewandten Forschung e.V., Germany (“Fraunhofer”), Europe’s largest application-oriented research organization. CeraMedic states that Fraunhofer, the assignee of over 1,500 U.S. patents, assigned ownership of the ‘584 patent to CeraMedic in early 2014.

CeraMedic indicates that non-party CeramTec GmbH (“CeramTec”) developed and manufactures BIOLOX Delta, an aluminum oxide matrix composite ceramic consisting of approximately 82% alumina (Al₂O₃), 17% zirconia (ZrO₂), and other trace elements.

CeraMedic then states that Defendant DePuy “designs, develops, manufactures, offers for sale, sells, uses, distributes, and markets hip implants, many of which include” CeramTec’s BIOLOX Delta and that such actions constitute infringement of the ‘584 patent. DePuy is accused of infringing the ‘584 patent directly, literally, and/or by equivalents.

The complaint, filed by New York patent attorneys in conjunction with Indiana patent lawyers, lists a single count: infringement of the ‘584 patent. CeraMedic asks the court for a judgment against DePuy determining that DePuy has infringed and continues to infringe one or more claims of the ‘584 patent; enjoining DePuy and its agents from further infringing the ‘584 patent; ordering DePuy to account for and pay to CeraMedic all damages suffered by CeraMedic as a consequence of DePuy’s alleged infringement of the ‘584 patent, together with interest and costs; trebling or otherwise increasing CeraMedic’s damages under 35 U.S.C. § 284 upon a finding that the asserted infringement by DePuy of the ‘584 patent was deliberate and willful; and declaring that this case is exceptional and awarding to CeraMedic its costs and attorneys’ fees in accordance with 35 U.S.C. § 285.
