LAST MPEG-4 VISUAL PATENT EXPIRES

MPEG-4 Visual patents, which have protected the codec since the mid-1990s, are now fully expired across all territories. The format has been essential infrastructure for digital video, powering everything from video streaming to mobile devices. The expiration eliminates licensing fees and legal barriers that previously required companies to obtain patents from the MPEG Licensing Administration. Developers can now implement MPEG-4 Visual without restrictions. This development may accelerate adoption in open-source projects and lower-cost implementations. However, MPEG-4 Visual has already been largely superseded by newer codecs like H.264 and H.265, which offer better compression efficiency. The codec remains in widespread use through existing deployed systems and legacy content. Its patent expiration primarily benefits new implementations and academic research rather than representing a major industry shift, as focus has already moved to next-generation video compression standards.
