On June 16, 2025, the U.S. Court of Appeals for the Federal Circuit (“CAFC”) vacated a $300 million damages award because the district court used a flawed verdict form, which included only a single, blanket question as to infringement when the case involved five asserted patents. Optis Cellular Tech., LLC v. Apple Inc., No. 2022-1904, 2025 WL 1680253 (Fed. Cir. June 16, 2025).  

Mirror Worlds Technologies, LLC ("Mirror Worlds") owns U.S. Patent Nos. 6,006,227; 7,865,538; and 8,255,439, which claim methods for storing, organizing, and presenting data in time-ordered streams on a computer system.  In 2017, Mirror Worlds filed suit against Meta Platforms, Inc. (formerly Facebook, Inc.) in the U.S. District Court for the Southern District of New York (“District Court”), alleging that several Facebook features infringed the patents.
