USPTO Director Vacates PTAB Decision Over ITC Inconsistency

USPTO Director Kathi Vidal’s successor vacated a PTAB final written decision in an inter partes review involving Sun Pharmaceuticals.

The PTAB had found certain claims unpatentable, but an ITC proceeding reached the opposite conclusion on identical claims, prior art, and grounds.

The Director cited inconsistency as grounds for vacatur. The action affects patent validity proceedings.
