AOMedia Video 1 (AV1) was invented by a group of technology companies to be an open, royalty-free alternative to other video codecs, like HEVC/H.265. But a lawsuit that Dolby Laboratories Inc. filed this week against Snap Inc. calls all that into question with claims of patent infringement.
Numerous lawsuits are currently open in the US regarding the use of HEVC. Relevant patent holders, such as Nokia and InterDigital, have sued numerous hardware vendors and streaming service providers in pursuit of licensing fees for the use of patented technologies deemed essential to HEVC.
It’s a touch rarer to see a lawsuit filed over the implementation of AV1. The Alliance for Open Media (AOMedia), whose members include Amazon, Apple, Google, Microsoft, Mozilla, and Netflix, says it developed AV1 “under a royalty-free patent policy (Alliance for Open Media Patent License 1.0)” and that the standard is “supported by high-quality reference implementations under a simple, permissive license (BSD 3-Clause Clear License).”
Yet, Dolby’s lawsuit filed in the US District Court for the District of Delaware [PDF] alleges that AV1 leverages technologies that Dolby has patented and has not agreed to license for free and without receiving royalties. The filing reads:
[AOMedia] does not own all patents practiced by implementations of the AV1 codec. Rather, the AV1 specification was developed after many foundational video coding patents had already been filed, and AV1 incorporates technologies that are also present in HEVC. Those technologies are subject to existing third-party patent rights and associated licensing obligations.
Dolby is seeking a jury trial, a declaration that Dolby isn’t obligated to license the patents in questions under FRAND (fair, reasonable, and non-discriminatory) licensing obligations, and for the court to enjoin Snap from further “infringement.”
Dolby claims infringed patents are “critical” to Snapchat’s business
Dolby is accusing Snap of infringing upon four of its patents: U.S. Patent No. 10,855,99 “Inter-plane prediction”; U.S. Patent No. 9,924,193 “Picture coding supporting block merging and skip mode”; U.S. Patent No. 9,596,469 “Sample array coding for low-delay”; and U.S. Patent No. 10,404,272 “Entropy encoding and decoding scheme.”

Executive Summary
Full Take
In analyzing this article, it is important to consider the implications of this lawsuit on the open and royalty-free nature of AV1 as a video codec, as well as the potential impact on companies that have adopted AV1 in their products or services. The lawsuit also raises questions about the patent landscape for video coding technologies and the potential for litigation over their use.
It is worth noting that this is not the first time lawsuits have been filed regarding the use of HEVC, with relevant patent holders such as Nokia and InterDigital suing numerous hardware vendors and streaming service providers in pursuit of licensing fees for the use of patented technologies deemed essential to HEVC.
The lawsuit also highlights the potential challenges of developing open standards in a competitive market where companies hold patents for various technologies. It is worth exploring whether there are mechanisms that could be put in place to mitigate these challenges and ensure the continued development and adoption of open standards such as AV1.
Additionally, it is important to consider the motivations behind Dolby's decision to file this lawsuit against Snap. Is it a strategic move to protect its intellectual property and market position, or does it reflect a broader concern about the erosion of patent rights in the video coding industry? These questions merit further exploration.
Patterns detected: none.
