A 25-year-old MPEG-4 Part 2 patent in Brazil expired, easing distribution of DivX/Xvid but leaving modern codec issues unresolved

# What expired and why it matters

The patent's expiry removes a Brazil-specific legal obstacle. MPEG-4 Part 2 patents previously expired in other jurisdictions: the EU patent ended in April 2021 and the US patent in December 2022. With Brazil's patent gone, the particular patent coverage for MPEG-4 Part 2 no longer blocks distribution in that country.

# Why Linux users care

Removing Brazil's MPEG-4 Part 2 patent reduces that risk for DivX/Xvid implementations. Distributors and developers can more confidently include or make available these legacy codecs without that specific patent exposure, which simplifies access to older video archives and compatibility workflows.

# What this does not change DivX and Xvid are largely legacy codecs. They remain useful for older archives and some hardware compatibility scenarios, but they are not the codecs that dominate modern video delivery. H.264 (MPEG-4 Part 10 / AVC) is still the dominant codec in many contexts, and patents covering H.264 remain in force in multiple jurisdictions.

A specific Dolby patent (BRPI0304568B1) tied to H.264 remains active in Brazil and is scheduled to expire in late 2030 according to publicly compiled patent timelines. Until patents for H.264 and its most common profiles expire more broadly, the Linux and open-source ecosystems will still face legal complexity for the codecs that power most current streaming and playback.

# Short-term practical effects

• Easier distribution of DivX/Xvid in Brazil for package maintainers and distro vendors.
• Simplified legal posture for developers who need to support legacy MPEG-4 Part 2 content.
• Little immediate change for mainstream video playback workflows, since H.264 and other modern codecs remain patent-encumbered.

# Medium- to long-term view for Linux multimedia This patent expiry is a step toward reducing codec-related friction for open-source distributions, but it is incremental. The more significant change for everyday Linux video playback will arrive only when patents covering widely used modern codecs lapse across major jurisdictions. Until then, distributions will continue to navigate a mixed environment where some older codecs are clear to distribute and newer, more widely used codecs still carry licensing considerations.
