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.

Domestic Industry Alive and Well at ITC; Important New Opinion Continues Trend

February 1, 2022 | Blog | By Jonathan Engler, Marguerite McConihe, Michael Renaud

The U.S. International Trade Commission (the “ITC”), in an important new opinion, recently extended a series of final determinations that complainants had satisfied the “economic prong” of Section 337’s domestic injury requirement.  This decision reinforces the Commission’s critical role in defending U.S. intellectual property rights and bodes well for patent owners.  In Certain Percussive Massage Devices, Inv. No. 337-TA-1206, the Commission found that complainant Hyperice Inc. proved it had “significant” domestic industry investments in labor, notwithstanding that all of the domestic industry devices were manufactured overseas.  Indeed, thus far in 2022, the Commission has found the economic prong of the domestic industry requirement satisfied in all four public final determinations.  In 2021 and 2022 combined, the Commission found the economic prong of the domestic industry requirement satisfied in 80% of all patent-based investigations that resolved on the merits, demonstrating that Complainants with well-organized, substantiated domestic industry cases continue to meet with success at the ITC.
