Computer-aided detection firm Intelligent Systems Software and suitor Howtek said today that they believe R2 Technology's patent-infringement lawsuit is without merit, and that they will vigorously defend against it. R2 announced yesterday that it had filed a complaint against Boca Raton, FL-based ISSI, alleging infringement of three R2 patents.
The complaint, filed in the U.S. District Court for the District of Delaware, asks for a permanent injunction against further infringement and unspecified damages. ISSI and Howtek of Hudson, NH, said they expect the lawsuit will not have an impact on their proposed merger, announced in January.

![A normal mammogram confirmed by three-year radiologic follow-up illustrates reader-marked regions of interest (ROIs) during (A) unaided (round 1) and (B) artificial intelligence (AI)–assisted (round 2) reading. Each colored dot represents an ROI for recall by a human reader. Readers could mark more than one ROI per case, represented by multiple dots of the same color. During AI-assisted reading, the AI system displayed three visible prompts: two with suspicion of malignancy scores of 35% (left mediolateral oblique [L MLO] and craniocaudal [L CC]) and one with a suspicion of malignancy score of 10% (right craniocaudal [R CC]), shown as polygonal overlays. Without AI, six of 10 readers (60%) marked a false-positive ROI. With AI assistance, this fell to two of 10 (20%). R MLO = right mediolateral oblique.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/07/2026-07-14-radiology-mammogram-ai-auto-bias.H0bYO8QlWs.jpg?auto=format%2Ccompress&fit=crop&h=112&q=70&w=112)
