Kroy IP's dispute with Groupon continued to generate Federal Circuit activity over IPR estoppel and unadjudicated patent claims.

The 2025 order followed earlier treatment of whether a Board final written decision can preclude litigation over claims not actually adjudicated in the IPR.

The case is valuable for litigation planning because patent families often include similar claims that were not all before the Board. Estoppel analysis must respect that procedural boundary.

IPDispatch should track this matter as part of the 2025 IPR-to-district-court interface, not just as a loyalty-program patent fight.
