A Business Deal Could Kill Your Right to Challenge a Patent’s Validity

February 22, 2022 | Blog | By William Meunier, Peter Cuomo, Marguerite McConihe, Sean Casey

Last week, the Federal Circuit issued a decision holding that parties can contractually bargain away their rights to file petitions for Inter Partes Review (“IPR”) at the Patent Trial and Appeals Board (“the Board”). This precedential case is the first to hold that a forum selection clause can forfeit the right to challenge a patent’s validity by IPR. The takeaway from this case is that when entering into any type of patent related agreement, be careful to ensure that your right to file IPR petitions is not stripped away, particularly by way of a forum selection clause which is “prima facie valid and should be enforced” in the words of the Federal Circuit.

When faced with an instituted IPR, the Patent Owner should include all arguments it wishes to preserve for appeal in its Patent Owner Response (“POR”), including arguments that the Patent Owner believes are unlikely to succeed before the Board but may be attractive to the Federal Circuit.  Otherwise, the argument will be deemed waived and unavailable in any subsequent appeal.
