A new lawsuit is challenging the legal bedrock of the AV1 video codec, a standard engineered to be free from licensing fees. Dolby Laboratories has filed a patent infringement case against Snap Inc. in Delaware federal court, alleging that the AV1 implementation used in Snapchat violates four Dolby patents.

AV1 was developed by the Alliance for Open Media—a consortium including Amazon, Apple, Google, and Netflix—specifically as an open, royalty-free alternative to codecs like HEVC. The alliance maintains its patent policy is designed to prevent such legal claims. Dolby’s suit, however, argues that AV1 incorporates foundational video technologies already covered by its intellectual property, for which it has not agreed to provide free licenses.

In the filing, Dolby states that the AV1 specification was built upon existing patented technologies, some of which are also present in HEVC, and are therefore subject to third-party licensing. The company is seeking a jury trial and an injunction to stop Snap’s alleged infringement. The patents in question relate to core video compression techniques like inter-plane prediction and entropy encoding.

For data and machine learning engineers who rely on AV1 for efficient video processing and streaming at scale, this case introduces uncertainty. It probes whether the ‘royalty-free’ promise can hold if foundational patents held by non-members, like Dolby, are deemed essential. The outcome could influence codec selection and infrastructure planning, potentially affecting cost and legal risk for engineering teams deploying AV1 in production systems.
