Computer-aided detection (CAD) developer iCAD has charged CAD firm R2 Technology with infringing on its patents. The Nashua, NH-based firm filed the latest chapter in ongoing litigation between the companies in the U.S. District Court for the District of New Hampshire. In its filing, iCAD charges its Sunnyvale, CA-based competitor with infringing on a 1993 patent issued to Stereometrix (now Scanis), to which iCAD is the exclusive licensee.
The company is charging that R2’s Image Checker system for investigating mammograms for masses and calcifications infringes its patent. iCAD seeks a permanent injunction against sale by R2 of infringing products, together with treble damages, costs and legal fees.
The two companies are already involved in litigation: R2 filed a patent infringement suit against iCAD last year, charging the company with infringing on three R2 patents.
