Litigation Status of Patent EP2449782B1 and its U.S. Family Members
As of May 1, 2026, there is no known record of U.S. litigation involving European patent EP2449782B1. As a European patent, it cannot be the direct subject of a patent infringement lawsuit in United States federal courts. Litigation in the U.S. would have to involve a corresponding U.S. patent from the same family.
The patent family of EP2449782B1 includes U.S. patent publication US20120106629A1. A search for litigation involving this specific U.S. family member or other granted U.S. patents in the family did not yield any specific case records in U.S. District Courts or the Court of Appeals for the Federal Circuit (CAFC).
However, the authoritative patent document for EP2449782B1 indicates that the patent family is involved in litigation, citing data from the Darts-ip database (Family ID=42710491). This suggests that lawsuits involving patents from this family have occurred in jurisdictions outside the United States.
Furthermore, the original assignee, Thomson Licensing SAS (now part of InterDigital), has been involved in extensive patent litigation globally concerning video compression standards such as AVC (H.264) and HEVC (H.265), which is the subject matter of this patent. Recent and ongoing litigation campaigns by InterDigital have targeted major technology and media companies, although these cases often involve broader portfolios of patents essential to these standards.
For instance, InterDigital has recently been in high-profile legal disputes with The Walt Disney Company in Germany and Brazil over patents related to AVC and HEVC video coding technology. In August 2025, Disney filed a complaint in the U.S. against InterDigital and Thomson Licensing SAS, alleging abusive patent-licensing practices related to these standards. While these cases concern the same technological field as EP2449782B1, and involve the same original assignee, it is not confirmed that EP2449782B1 or its direct U.S. counterparts were asserted in these specific actions.
In summary, no U.S. litigation has been identified for the direct U.S. family members of EP2449782B1. However, the patent family is noted as having been litigated in other jurisdictions, and the original assignee is a frequent litigant in the relevant technology sector.
