Introduction
This article explains what the Audio technology package covers in IPlytics, the data sources behind it, and how customers can use it for SEP and standards analysis.
A technology package (also called a feature package) is a curated collection of patents covering a specific technology standard – for example, Wi-Fi 6, 5G, or HEVC video compression. Rather than constructing a patent search from scratch, users of the IPlytics platform can access these packages directly to immediately explore which companies hold relevant patents, how many patents exist in the landscape, and which may be essential to a given standard.
The Audio technology package covers patent landscapes in audio coding technologies for four major codec standards: AAC, Opus, EVS, and MPEG-H 3D Audio. It's built for tracking patent ownership, portfolio strength, competitive position, and licensing exposure across these technologies, developed within the ISO/IEC, IETF, and 3GPP standards ecosystems.
Please note: The Audio technology package covers IPlytics audio coding landscapes for AAC, Opus, EVS and MPEG-H 3D Audio. These landscapes were added to support analysis of audio coding patent overlaps, potential licensing opportunities and technology-specific patent risk. Availability of individual landscapes, contribution data, pool reference data and royalty calculator views may depend on your subscription and platform configuration.
What The Package Covers
The Audio technology package focuses on audio coding standards developed across ISO/IEC, IETF, and 3GPP, and organizes the data into four codec-specific landscapes.
Users can filter by codec landscape and review available declaration, pool, and IPlytics' classifier-based undeclared patent data for each technology.
| Codec | What It Covers | Typical Relevance |
| AAC (Advanced Audio Coding) | A lossy digital audio compression standard standardized by ISO/IEC as part of MPEG-2 and MPEG-4. AAC is widely used for streaming, mobile audio, digital media, and consumer audio devices. | Streaming, mobile audio, digital media, and consumer audio devices. |
| Opus | An IETF-standardized audio codec, defined in RFC 6716 and related RFCs, designed for interactive speech and music transmission over the internet. Opus combines technology from Skype's SILK codec and Xiph.Org's CELT codec. | Real-time communication, VoIP, and WebRTC-related use cases. |
| EVS (Enhanced Voice Services) | A 3GPP audio codec technology associated with TS 26.441 through TS 26.450 classifications in IPlytics, supporting enhanced mobile voice and audio service analysis. | Enhanced mobile voice and telecom network audio services. |
| MPEG-H 3D Audio | An ISO/IEC audio coding and rendering standard for high-quality spatial and immersive audio. | Broadcast, wireless streaming, immersive media, and object-based or spatial audio experiences. |
Note on Coverage: IVAS may be relevant as an adjacent 3GPP immersive audio technology, particularly in relation to MPEG-H 3D Audio and EVS analysis, but it is not currently included as a separate Audio technology package landscape. Contact the IPlytics team if IVAS-specific access is required.
What Users Can Analyze
- Search and filter patent families by audio coding technology, including AAC, Opus, EVS, and MPEG-H 3D Audio.
- Review declared, pooled, and classifier-based undeclared patent data, including Via LA pool sources for AAC and MPEG-H 3D Audio, Vectis IP pool and IETF IPR disclosure sources for Opus, and 3GPP TS classifications for EVS.
- Review ownership rankings and benchmark portfolios across companies and codec-specific landscapes.
- Review available standards-body and contribution context, including ISO/IEC, IETF, and 3GPP-related information depending on the technology.
- Royalty Calculator Support: Use available pool reference rates and patent-stack share information to support royalty exposure scenarios. Note that these outputs should be treated as analytical estimates, not as invoices, legal opinions or final FRAND determinations.
- Export row-level search results and use analytics views for visual breakdowns and comparison.
Why It Matters
Audio codecs are embedded in a wide range of connected products, including smartphones, laptops, tablets, smart TVs, wireless earbuds, smart speakers, gaming headsets, conferencing tools, and automotive infotainment systems. Different codecs sit within different standards bodies, patent pools, and declarant groups, so licensing risk and pool coverage can vary significantly by technology.
Standards bodies such as ISO/IEC, IETF, and 3GPP rely on self-declared essentiality, where companies voluntarily disclose which patents they believe are essential to a given standard. In practice, these declarations are frequently over-broad, outdated, or incomplete, so they don't reliably show who actually holds relevant patents. The Audio technology package addresses this by classifying and organizing patents into structured, codec-specific landscapes that combine declared, pooled, and undeclared data, giving users visibility into the landscape independent of what's been formally declared.
Common Use Cases
- Licensing preparation: identify companies associated with declared, pooled, and undeclared audio coding patent data for selected codec technologies.
- Patent pool assessment: review available pool coverage and compare pool participants with other patent holders in a codec-specific landscape.
- Portfolio benchmarking: compare a portfolio against competitors across AAC, Opus, EVS, and MPEG-H 3D Audio landscapes.
- Risk prioritization: identify patent families, rights holders, and technology areas that may require further technical or legal review.
- Royalty scenario analysis: use the royalty calculator and available pool reference data to estimate possible exposure scenarios and compare them with external royalty demands.
Important Scope Note
| The package provides research and analytics for audio coding patent landscapes, including pool references, contribution metrics, and royalty calculator outputs. These outputs are intended to support research and prioritization. They do not determine essentiality, validity, infringement, enforceability, licensing obligations, or FRAND compliance, and do not replace technical claim-charting or legal review. |
How To Request Access
The Audio technology package is a licensed add-on to the IPlytics Platform. Access is not included automatically in every standard platform subscription. Some related capabilities, including individual audio coding landscapes, pool reference data, or royalty calculator views, may require separate entitlement or configuration.
