We’re proud to share that Law360 has named Sunstein LLP’s Federal Circuit win in Ingenico Inc. v. IOENGINE LLC one of the top patent decisions from the first half of 2025! Congratulations to Kerry L. Timbers and Kevin R. Mosier, who represented Ingenico in this widely followed patent dispute.
The ruling marked a full victory for Ingenico and resolves a split among district courts on the scope of IPR estoppel — a key issue for patent litigation strategy: https://www.sunsteinlaw.com/publications/news/law360-federal-circuit-ingenico-triumph
