From the music streaming on our phones to the crisp dialogue in a video conference, digital audio is central to how we connect and communicate. Audio codecs—such as AAC, Opus, MPEG-H, and EVS—compress and decompress digital sound, delivering seamless, high-quality listening experiences across apps, devices, and industries. Whether optimizing for real-time calls, immersive spatial sound, or low-bitrate streaming, these codecs make modern digital life possible. get the report Why read this report? As audio technology gains traction, navigating its Standard Essential Patent (SEP) landscape is becoming increasingly critical for organizations across streaming, telecom, consumer electronics, and automotive sectors. This report provides strategic clarity for IP, licensing, and legal professionals—uncovering both declared and undeclared patents across AAC, Opus, MPEG-H, and EVS to support smarter decisions around licensing, risk management, and portfolio strategy. Inside you will discover Insight into undeclared patents not listed in public declarations or patent pools A ranking of top patent owners across AAC, Opus, MPEG-H, and EVS A comparative overview of patent pool programs, licensing rates, and coverage gaps for each codec Regional analysis of SEP owners and implementers by geography and industry Strategic insights to assess portfolio strength, anticipate licensing exposure, and prepare for FRAND negotiations Download The Report Unlock the Full Audio Codec Patent Landscape Submit the form to get immediate access to the full report and explore key patent owners in the audio codec space. 2025 Audio Codec Report Cellular Verified How We Identified Undeclared Audio Codec Patents We used AI-powered Classification (powered by Cipher) to identify patents potentially essential to the AAC, Opus, MPEG-H, and EVS standards—yet not officially declared. Experts validated the results to ensure accuracy, and classification models were trained iteratively for precision. Learn how to navigate the undeclared audio codec patent landscape How did we uncover undeclared patents and rank portfolio owners? ‘Who is Leading the Audio Codec Patent Race’ report is grounded in a rigorous methodology that combines AI-powered patent Classification (powered by Cipher), expert validation, and proprietary ownership mapping to identify patents potentially relevant to AAC, Opus, MPEG-H, and EVS that are not publicly declared. The analysis integrates data from LexisNexis® IPlytics™ and PatentSight+™, applying consistent cut-off dates, quality metrics, and legal status checks to deliver a transparent view of both declared and undeclared patent landscapes. For full details, visit our methodology page. The Complex Audio Codec Patent Landscape The audio codec patent landscape is highly fragmented—shaped by multiple licensing pools, evolving ownership, and widespread use of blanket declarations. Many critical patents remain undeclared, making it difficult for companies to fully understand their licensing exposure. IPlytics brings clarity to this complexity by combining AI-powered patent classification, ownership tracking, and public royalty data to help stakeholders see who owns what, what’s declared, and what remains hidden.
