OpenEvidence and Doximity Settle Dueling AI Prompt-Injection Suits After Prompt-Hack Claims

Healthcare AI startups OpenEvidence and Doximity settled in principle on Thursday and dismissed all claims and counterclaims with prejudice on Friday in the U.S. District of Massachusetts. OpenEvidence's June 2025 suit accused Doximity staff of impersonating physicians via real NPI numbers to prompt-inject OpenEvidence's medical chatbot and extract secrets. Each side will bear its own fees; no damages or injunction were awarded, with other financial terms undisclosed.
