THE CAFC DECIDES ON CERTAIN RULES RELATING TO IPR PROCEEDINGS

By: Mel R. Quintos

 

The U.S. Court of Appeals for the Federal Circuit (CAFC) recently decided two precedential cases relating to inter partes review (IPR) proceedings.

 

  1. In Fairchild (Taiwan) Corporation v. Power Integrations, Inc., Fairchild (owner of U.S. Patent No. 7,259,972, “the ‘972’ patent’’) sued Power Integrations for infringement of certain patents, including the ‘972 patent. Pertinent claims of the ‘972 patent include:
    1. a first set of claims (claims 6, 7, 18, and 19) raised at trial, and
    2. a second set of claims (claims 1, 2, 5-7, 11, 12, 15, 17-19, 22, 32, 34, and 52-66) subjected to a later IPR proceeding.
