Fortress Investment entity DivX video playback patent challenged

On July 20, 2026, Unified Patents filed an ex parte reexamination proceeding against U.S. Patent 10,576,716, owned and asserted by DivX LLC, an NPE and entity of Fortress Investment Group LLC. The ‘716 patent is generally directed to progressive video playback systems where a client application on a device retrieves portions of a media file from a remote server and plays the media as it is being downloaded. The ‘716 patent has not been asserted in litigation, however, it is related to U.S. Patent 10,412,141 which was asserted against Realtek, TCL, Samsung, Hulu, and Amazon.
