Indiana Patent Litigation: Ligchine Asks Federal Court to Declare That It Has Not Infringed

New Albany, Indiana – Patent attorneys for Ligchine International Corporation of Floyds Knob, Indiana initiated a patent lawsuit in the Southern District of Indiana seeking declaratory judgment of non-infringement. Defendant is Somero Enterprises, Inc. of Houghton, Michigan.

This federal lawsuit is in response to a June 2016 letter sent to Ligchine by patent lawyers for Somero. In this letter, Somero asserted that Ligchine was engaged in the manufacture, use, offer for sale, sale and/or distribution of concrete screeding machines containing a “Paver/Superflat Combo Screed Head that includes a powered roller option.” Somero contended that such conduct infringed Somero’s patent rights in U.S. Patent Nos. 9,234,318 and 9,353,490, which have been registered with the U.S. Patent and Trademark Office. Somero threatened litigation if the alleged infringement did not cease.

Ligchine asserts that it has not infringed either patent and asks the court for a declaration of non-infringement for each of the two patents-in-suit. It also asks the court to order reimbursement of its costs of the lawsuit, including attorneys’ fees.

This lawsuit was assigned to Chief Judge Richard L. Young and Magistrate Judge Tim A. Baker in the Southern District of Indiana and assigned Case No. 4:16-cv-00125-RLY-TAB.
