A 25-Year-Old Brazilian Video Patent Just Expired, Ending a Lingering Legal Headache for Linux
A 25-year-old video patent just expired, ending a legal headache for Linux

A Brazilian patent filed by Siemens AG in 2001, part of the MPEG-4 Visual Patent Portfolio, expired on July 19, 2026. This removes the last patent obstacle preventing MPEG-4 Part 2 (DivX/Xvid) from being patent-free worldwide. While the patent didn't significantly hinder Linux distributions—Fedora even shipped xvidcore in 2023—it did impose legal restrictions on royalty payments for MPEG-4 decoders and encoders in certain countries. The expiration marks the end of a minor but persistent legal issue for the open-source community, though modern video formats like H.264/AVC (MPEG-4 Part 10) remain under patent.
So, yeah, the Linux community isn't free to take the MP4 format and run with it wherever it pleases.

What other tech patents did we somewhat resent being patented that are now expired?
I'm also thinking about the click wheel; I got one of my kids a knockoff iPod for Christmas last year.
Can other e-commerce sites legally "one-click" to purchase like Amazon now?!?

> The videos we watch on modern systems using H.264/AVC tech are running off MPEG-4 Part 10, and that is still very much covered by patents.
I dispute "very much". It came out in 2004 and almost all the patents are gone.

I remember DivX fondly. Even on dialup, picture quality was just phenomenal. Web tv watching was actually doable after this
edit: I am talking about divx web player

Siemens holding one of the key patents in video codecs surprises me. I am not technically savvy, but I thought telecom infrastructure or direct media companies would hold the most important patents on this.

> MPEG-4 Part 2
Yes, if you care about the DVD-era still. If not, this expiry doesn't have a big impact on anything.

Brazil? Why a Brazilian patent is of such a significant interest elsewhere?
