Cardiff Oncology sues Nerviano Medical Sciences over onvansertib license inventorship dispute
--------------------------------------------------------------------------------

- Filed suit in SD California for injunctive relief and declaratory judgment it did not breach license agreement for onvansertib.
- Dispute stems from NMS allegation that Cardiff failed to name an NMS employee as joint inventor on U.S. Patent Nos. 12,144,813 and 12,263,173.
- Cardiff maintains no breach occurred; agreement does not require naming NMS employees on inventions made solely by Cardiff.
- NMS sent written notice of alleged material breach on February 24, 2026, as previously disclosed.
- Judicial intervention sought after prior discussions failed to resolve the disagreement.
