Last MPEG-4 Visual patent expires globally
The final patent for the MPEG-4 Visual standard expired in Brazil on July 19, 2026, officially clearing the patent landscape worldwide for legacy codecs like Xvid and DivX. While this enables risk-free open-source bundling of MPEG-4 Part 2, it has no impact on newer, still-patented standards like H.264/AVC.
While the clearance of MPEG-4 Visual is a milestone, it represents a symbolic victory for legacy media preservation rather than a shift in modern web media distribution.
* Safe legacy support: Developers and open-source distributions can now bundle MPEG-4 Visual encoders and decoders globally without any remaining patent risk.
* Regional IP complexity: The dependency of the entire patent pool on a single Brazilian patent illustrates how regional differences in patent registration and prosecution terms affect global compliance.
* Irrelevance to modern video: Because modern video infrastructure has shifted to H.264, HEVC, VP9, and AV1, this expiration has minimal practical impact on contemporary streaming workloads.
