Description
To identify relevant patents, comprehensive searches were conducted across multiple patent databases using a combination of search strings, IPC/CPC classifications, and HEVC–specific keywords.
To determine the essentiality of a patent, each claim is compared to the H.265 standard to identify whether the patented claim’s elements are present in the standard. Essentiality is checked with respect to all versions of HEVC, respectively, as improvements have been gradually implemented to address evolving technological demands in HEVC.
Patented claim is compared to the standard, and if every element of the claim aligns with the H.265 specifications, the patent is considered essential. On the other hand, if any element is not present or there is a contradiction between the claim and the standard (e.g., conflicting requirements or descriptions), the patent is considered non-essential. This manual evaluation process ensures that only patents fully aligned with the H.265 standard’s requirements are classified as essential.
Frequently asked questions
What does this report cover about ETRI’s HEVC patents?
It sets out an essentiality analysis of ETRI’s patent portfolio against the HEVC/H.265 standard. The set covers 73 active granted patents identified for ETRI that relate to HEVC technology. The analysis spans Block-based coding, Predictive Coding, Transformation and Quantization, Multi-layer and Filtering. Each patent was evaluated by manually mapping the elements of its independent claims to the relevant sections of the standard, which shows where the claimed subject matter matches the specification and where it does not.
How is each patent mapped to the standard?
Independent claims are broken into elements, and each element is compared with the relevant sections of the H.265 specification. Where every element of a claim aligns with the standard, the patent is considered essential. Where an element is not present, or the claim conflicts with the standard through contradictory requirements or descriptions, the patent is considered non-essential. Essentiality is checked across all versions of HEVC, since features were added gradually. The mapping is done by hand, so each conclusion can be traced to a section of the standard.
Who is this report for?
It suits licensing teams, IP counsel, patent pool administrators and technical decision makers who need an independent view of ETRI’s HEVC position. The claim to standard mapping supports licence discussions, portfolio valuation, benchmarking against other holders and preparation for pool submissions. Research and standards groups also use this type of mapping to see which coding tools a portfolio covers. The level of detail lets a reviewer check each conclusion against the standard rather than accept a summary count.
How is the report obtained?
It is supplied on request through the contact page on the website. There is no online purchase and no instant download, so the report is shared after you send an enquiry describing what you need. Scope can be adjusted before delivery. If you want a single technology area, a different patent set, a family level view, or a comparison with another HEVC portfolio, mention that in the enquiry and the analysis can be prepared to match.
