The Federal Circuit’s decision in Focus Products Group International, LLC v. Kartri Sales Co., Inc. delivers a wide-ranging opinion that touches nearly every corner of intellectual property litigation: venue after TC Heartland, prosecution history disclaimer, multi-defendant appellate waiver, trademark standing, trade dress functionality, willfulness, and fee shifting. But at its core, the case stands as…

The Federal Circuit’s September 25, 2025 decision in Apex Bank v. CC Serve Corp. offers an important reminder that the DuPont likelihood-of-confusion factors are not a cafeteria menu.

The Federal Circuit’s decision in Magēmā Technology LLC v. Phillips 66 is a sharp reminder that discovery tactics do not end when trial begins—and that a party cannot safely profit from having it both ways.

The Federal Circuit’s recent en banc decision in V.O.S. Selections, Inc. v. United States addressing challenges to former President Trump’s sweeping tariff regime represents one of the most consequential trade-law rulings in decades.

The Federal Circuit’s August 29, 2025 decision in Hyatt v. Stewart brings a long-running saga back to a firm stopping point.
