Tissue Extraction Devices, LLC Sues Hologic, Inc. and Suros Surgical Systems, Inc. for Patent Infringement of Breast Biopsy Device


Indianapolis, IN – Patent lawyers for Tissue Extraction Devices, LLC of Indianapolis, Indiana filed a patent infringement suit alleging Hologic, Inc. of Bedford, Massachusetts and Suros Surgical Systems, Inc. of Indianapolis, Indiana infringed Patent No. 7,749,172, PNEUMATIC CIRCUIT, which has been issued by the US Patent Office.

The patent infringement complaint alleges that Jeff Schwindt, owner of Tissue Extraction Devices, invented the technology at issue, which is apparently a hand-piece used by doctors who are performing breast biopsies. Mr. Schwindt assigned the patent rights to Tissue Extraction Devices. The hand-piece allows the doctors to remove a tissue sample for biopsy. According to the complaint, Schwindt worked together with Suros to further develop the hand-piece. Schwindt, however, is the owner of the patent on the hand-piece. Suros introduced breast biopsy systems that included the hand-piece to the market under the names ATEC and EVIVA. Suros is a wholly owned subsidiary of Hologic. Tissue Extraction claims these two systems infringe upon the patent owned by Schwindt. Tissue Extraction’s patent infringement attorneys have requested a declaratory judgment that the patent has been infringed, damages, and attorney fees.

This case has been assigned to Judge Tanya Walton Pratt and Magistrate Judge Tim A. Baker in the Southern District of Indiana, and assigned case no. 1:11-cv-00628-TWP-TAB.

Practice Tip: Based on the complaint, this lawsuit appears to be the result of a dispute between an inventor and another party who participated in some way in the development or marketing of the invention. This case illustrates the importance of having a clear agreement regarding intellectual property rights before parties begin working together to invent, develop and market a product.
