AV1 Video Codec Patent Pools and Licensing: Alliance for Open Media Strategies

TL;DR
AV1 is a royalty-free video codec developed by the Alliance for Open Media (AOMedia). While the codec specification itself carries no royalties, certain implementations and essential patents held by members have led to the formation of patent pools and licensing programs. Streaming services and chipset makers must still conduct freedom-to-operate and evaluate pool licenses. See our 5G SEP FRAND licensing guide by the PatentPaper research team for comparable essentiality and rate-setting analysis and our MPEG patent pools FRAND guide by the PatentPaper research team for historical codec pool structures.

AV1 Specification, AOMedia Membership and Royalty-Free Commitments

AOMedia members contributed technology under reciprocal royalty-free licenses for the AV1 bitstream specification. However, members retain rights to patents that read on specific encoder or decoder implementations, hardware acceleration, or optional features. This creates a distinction between the specification and commercial implementations.

Example: A major streaming platform adopted the open-source libaom encoder but later received licensing demands from a pool covering hardware-optimized AV1 decode blocks in set-top chips; the platform ultimately took a pool license for its device certification program.

Patent Pool Formation: Sisvel, Access Advance and Independent Licensors

Multiple administrators have announced AV1 patent pools. Sisvel launched an AV1 patent pool in 2023 covering patents from several contributors. Other licensors operate independently or through Access Advance. Essentiality rates and portfolio strength vary significantly between pools, requiring careful claim-by-claim review before taking licenses.

Royalty Rates, Tiered Structures and Device Categories

Published AV1 pool rates are generally lower than HEVC pools, with per-unit caps and volume discounts. Some programs distinguish between software decoders, hardware decoders in consumer electronics, and professional encoding services. Content owners often receive pass-through rights or broader covenants not to sue.

Essentiality Assessment, Portfolio Review and Risk Allocation in Contracts

Because AV1 is newer, essentiality studies are less mature than for H.264 or HEVC. Licensees should commission independent essentiality opinions or rely on pool-provided claim charts. In supply chain contracts, responsibility for AV1 pool licenses is frequently allocated to the chipset supplier or the device brand owner depending on negotiation leverage.

Comparison with HEVC, VP9 and Future Codec Developments

VP9 remains royalty-free with no active pools. HEVC pools have faced antitrust scrutiny and rate disputes. AV1 adoption is strongest in web streaming and Android devices; Apple has been slower to adopt. Next-generation codecs (AV2, LCEVC, EVC) are already generating new pool formation discussions.

FAQ

Is AV1 truly royalty-free for all uses?

The AV1 specification is subject to royalty-free commitments from AOMedia contributors, but patents covering particular implementations, hardware, or optional tools may still require separate licenses from pools or individual owners.

Which companies are the largest contributors to AV1 patent pools?

Contributors include several major technology firms that participated in AOMedia development plus later patent sellers. Pool administrators publish lists of licensors on their websites.

How do AV1 pool rates compare to HEVC?

Current AV1 pool rates are typically 30-60% lower than equivalent HEVC rates, with lower caps and more generous volume tiers, though coverage and essentiality strength differ.

Do content providers need AV1 licenses?

Content owners usually receive broad covenants or pass-through rights under pool programs. The primary licensees are device manufacturers and software platform providers that implement encoders or decoders.

What due diligence should a device maker perform before shipping AV1 hardware?

Request pool claim charts, commission independent essentiality review for high-risk patents, review supply agreements for indemnification, and model royalty exposure under different volume scenarios.

Are there ongoing disputes or litigation involving AV1 patents?

Yes. Several pool licensors have asserted AV1 patents against implementers in multiple jurisdictions. Most disputes settle before trial, similar to other codec patent enforcement.

Which PatentPaper resources cover related video codec and SEP licensing topics?

Our 5G SEP FRAND licensing guide and MPEG patent pools FRAND guide by the PatentPaper research team provide frameworks for evaluating essentiality, rates, and pool structures applicable to AV1.

Review layer 1: Practical review notes for AV1 Video Codec Patent Pools and Licensing: Alliance for Open Media Strategies

Review layer 1: For av1 video coding patent pools, separate the legal basis, patent-office step, and commercial evidence needed in a dispute. Sources such as aomedia.org, sisvel.com, accessadvance.com help confirm fees, deadlines, term, and forum from primary material rather than secondary summaries.

Review layer 1: Before filing, licensing, assigning, challenging, or enforcing the right, keep a matrix with the application number, owner, prosecution status, payments, agreements, and related PatentPaper links. That record makes later decisions easier to defend.

Review layer 1: Check legal status before sending a notice.
Review layer 1: Save official receipts and office correspondence.
Review layer 1: Compare the main claim with the product actually sold.
