While our database tracks DivX LLC as a defendant in one case before the Patent Trial and Appeal Board (PTAB), external information indicates the company is an active patent licensor and plaintiff, often characterized as a Patent Assertion Entity (NPE) by organizations like Unified Patents. DivX has been involved in multiple patent infringement lawsuits as a plaintiff against major technology companies.
A notable case involving DivX LLC is Unified Patents v. Divx LLC at the PTAB, which was affirmed by the U.S. Court of Appeals for the Federal Circuit. This case centered on U.S. Patent No. 10,326,987 B2, related to adaptive bitrate (ABR) streaming video encoding systems, where the claims were ultimately found unpatentable. DivX's patent litigation activities, including suits against Amazon and Netflix concerning streaming and encryption technologies, are often connected to its ownership by entities affiliated with Fortress Investment Group.
