The final patent tied to MPEG-4 Part 2, also known as MPEG-4 Visual, has expired, according to Phoronix. The development marks the end of the patent life for a video standard that played an important role in digital media over the years.
MPEG-4 Part 2 was widely associated with an earlier generation of video compression and playback technologies. With the last patent no longer in force, the format now moves fully out of its long patent shadow.
For developers, distributors, and open-source projects, patent expirations like this can matter because they remove one of the legal barriers that may have complicated implementation or broader support. It also closes a notable chapter in the history of multimedia formats and codec licensing.
While newer video standards have largely taken over in modern streaming and media workflows, the end of the remaining MPEG-4 Visual patent is still a meaningful milestone for legacy codec history and software freedom discussions.
