MPEG-4 Visual Patents Fully Expire Globally

MPEG-4 Visual Patents Fully Expire Globally

MPEG-4 Visual is Now Patent-Free Worldwide

On July 19, 2026, the final remaining patent for MPEG-4 Visual (Part 2) expired, removing the last legal barrier to the royalty-free implementation of the standard globally. While patents in the United States and European Union had expired in previous years, a single remaining patent in Brazil—BRPI0109962B1, titled "process for storing and processing image information from successive images over time"—remained active until this date.

The VIA Licensing Alliance has confirmed that the expiration of this Brazilian patent marks the end of the MPEG-4 Visual patent portfolio.

Technical Scope: MPEG-4 Part 2 vs. H.264

It is critical to distinguish MPEG-4 Part 2 from the more modern H.264 (AVC) standard. The expiration of these patents applies specifically to the technology backing codecs such as Xvid and DivX, not to H.264.

Key Distinctions

  • MPEG-4 Part 2: The subject of this expiration. This standard powered the early 2000s era of digital video, specifically Xvid and DivX.
  • H.264 (AVC): A separate, newer standard. Patents for H.264 have not yet expired globally, and their expiration dates vary by jurisdiction.

Industry Context and Community Perspective

Despite the formal expiration, the practical impact on the current software landscape is limited due to the long-term prevalence of the codecs in open-source and consumer electronics.

Widespread De Facto Adoption

Many implementations of MPEG-4 Part 2 have existed for decades without formal licensing. Community members have noted that Xvid decoders were integrated into nearly all consumer hardware, such as Chinese DVD players, for the last 20 years.

Open Source Integration

In the Linux and open-source communities, the standard was often utilized via third-party repositories. One contributor noted:

"Too late; software patents in Europe were void so most people grabbed XVID/DIVX encoders from Debian Multimedia... and mencoder for sure."

While the legal status is now clear, the industry has largely moved toward higher resolution and higher bandwidth video standards, which may limit the renewed utility of MPEG-4 Part 2 in modern production environments.
