What happened
Doximity and OpenEvidence filed a joint notice of settlement in the U.S. District Court for the District of Massachusetts on Thursday, October 15, 2026, Bloomberg Law reported. The notice covers OpenEvidence's lawsuit against Doximity over alleged prompt hacking of its medical AI. Bloomberg Law reported that the joint notice did not provide details on the agreement and that counsel for the parties did not respond to requests for comment. If finalized, the settlement would conclude the case with prejudice.
In the suit, OpenEvidence accused Doximity executives of using stolen doctor credentials to gain access to OpenEvidence's AI and then questioning it with prompts meant to make it reveal secrets about how it is built. Bloomberg Law described the legal dispute between the two companies as brief but acrimonious. The coverage did not report whether any payment was involved, what each side agreed to, or when the court would close the case.
Key points
- Doximity and OpenEvidence filed a joint notice of settlement on October 15, 2026, in the District of Massachusetts.1
- The notice gave no settlement details, and counsel did not respond to requests for comment.1
- If finalized, the settlement would conclude the case with prejudice.1
- OpenEvidence had alleged Doximity executives used stolen doctor credentials to probe its AI with prompts.1
Why it matters
If the settlement is finalized, the case would conclude with prejudice, which would remove an open lawsuit between OpenEvidence and Doximity.
No amount or conditions were reported, so any payment by either side, or any limit on how either company operates, cannot be assessed from the coverage.
The suit centered on claims that a rival probed how OpenEvidence's AI is built. A notice of settlement does not itself resolve those allegations in public.
