Johnson & Johnson (J &J) subsidiary, Ethicon Endo-Surgery, has filed a lawsuit against Hologic, a medical imaging equipment company, accusing it of violating four patents on a tumor-detection system.

On Oct. 5, J &J filed a complaint in the U.S. District Court of Ohio, alleging that Hologic’s ATEC biopsy systems, including the Pearl, Sapphire and Emerald, infringe four of Ethicon’s patents. The ATEC systems are manufactured and sold by Suros Surgical Systems, a wholly-owned Hologic subsidiary.

The complaint seeks to stop Bedford, Mass.-based Hologic and Indianapolis-headquartered Suros from infringing the patents as well as the recovery of damages and costs from the alleged infringement, according to the SEC filing.

Ethicon said the infringement will continue to “irreparably” harm the company unless it is blocked.

In a regulatory filing, Hologic responded that it believes “the lawsuit is without merit and intends to vigorously defend its position.”
