TL;DR
The last patent covering MPEG-4 Visual technology has expired, marking the end of patent protections for this standard. This development could influence licensing costs and innovation in video compression.
The expiration of the last remaining patent related to the MPEG-4 Visual standard was confirmed in April 2024, effectively removing licensing restrictions that had been in place for years. This milestone allows for broader use of MPEG-4 Visual without licensing fees, potentially reducing costs and fostering innovation in digital video technology.
According to the MPEG LA licensing consortium, the final patent covering MPEG-4 Visual, a key video compression standard used in digital broadcasting, streaming, and multimedia applications, has officially expired as of April 2024. The patent, held by a patent holder whose identity has not been publicly disclosed, was part of a broader pool of patents that enabled licensing for MPEG-4 Visual since its inception in 2002.
Prior to this expiration, companies and developers needed to pay licensing fees to use MPEG-4 Visual technology, which could impact costs for hardware manufacturers, software developers, and content providers. The expiration effectively makes MPEG-4 Visual a free and open standard, similar to other legacy codecs that have entered the public domain.
Implications for Video Technology and Licensing Costs
This expiration could significantly reduce licensing costs for companies utilizing MPEG-4 Visual in their products, potentially lowering prices for consumers and enabling broader adoption. It may also encourage innovation, as developers are no longer constrained by patent licensing restrictions when implementing MPEG-4 Visual in new applications or devices. Additionally, the move aligns MPEG-4 Visual with other open standards, which can stimulate competition and technological advancement in digital video.

Background on MPEG-4 Visual and Patent Timeline
MPEG-4 Visual was introduced in 2002 as part of the MPEG-4 multimedia standard, designed for efficient video compression suitable for streaming and multimedia applications. Over the years, numerous patents were filed by various entities to protect innovations related to this standard. Licensing fees for MPEG-4 Visual were managed through MPEG LA, which pooled patents from multiple holders to streamline licensing.
For nearly two decades, patent holders maintained licensing restrictions, which impacted hardware manufacturers and software developers. The expiration of the last patent marks the end of this licensing era, making MPEG-4 Visual essentially free to use. The process of patent expiration is a natural part of patent law, typically occurring 20 years after filing, but in this case, the last patent’s expiration was confirmed after negotiations and legal reviews.
“The expiration of the last MPEG-4 Visual patent marks a significant milestone, opening the door for broader use and innovation without licensing restrictions.”

Key Questions
What does the expiration of the MPEG-4 Visual patent mean for developers?
It means developers can now implement MPEG-4 Visual without paying licensing fees, potentially reducing costs and enabling broader use in new applications.
Will existing products need to be updated or changed because of this?
Generally, no. Existing products that already use MPEG-4 Visual are not affected unless they rely on patents still held by other entities. The expiration mainly impacts future implementations.
Does this affect other MPEG standards like AVC or HEVC?
No. The expiration specifically applies to MPEG-4 Visual patents. Other standards like AVC or HEVC have separate patent pools and licensing arrangements.
While the last patent has expired, disputes could still arise over related technologies or improvements. However, the core MPEG-4 Visual standard is now in the public domain.
