CytomX Therapeutics Inc

On March 4, 2020, Vytacera Bio, LLC filed a patent infringement lawsuit against us in the U.S. District Court for the District of Delaware. The lawsuit alleges that our use, offers to sell, and/or sales of the PROBODY® technology platform for basic research applications constitutes infringement. The complaint seeks unspecified monetary damages. In September 2022, we filed a motion to dismiss the case and the Court granted the parties’ stipulation to stay all pending case deadlines until that motion is finally resolved. On October 30, 2023, Magistrate Judge Burke issued a Report & Recommendation that recommended granting CytomX’s motion to dismiss all counts of the complaint. In January 2024, the case was transferred to a new Judge and the case will remain stayed pending a ruling by the trial judge on the Magistrate’s Report & Recommendation. We believe that the lawsuit is without merit and intend to vigorously defend ourselves. Accordingly, we cannot reasonably estimate any range of potential future charges, and we have not recorded any accrual for a contingent liability associated with these legal proceedings.
