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 for JVC Kenwood and HEVC?
It is an essentiality analysis of JVC Kenwood’s patents against the HEVC/H.265 standard. A total of 154 active granted patents related to HEVC were identified. Each patent was evaluated by mapping its independent claim elements to the relevant sections of the standard, so the report shows where claims align with the specification and where they do not. The mapping covers the main technical areas of HEVC and points to the parts of high efficiency video coding that JVC Kenwood worked on.
Which technical areas of HEVC does the analysis cover?
Coverage spans block based coding, predictive coding, transformation and quantization, multi-layer and filtering. Those areas group the parts of the H.265 specification against which the claims were mapped. Placing each patent in one of these areas shows how the portfolio is spread across the standard rather than concentrated in a single part of it. The grouping also makes it easier to compare this portfolio with assessments built on the same areas.
How is a patent judged essential to H.265?
Each claim is compared with the H.265 standard to see whether the elements of the claim appear in it. If every element of a claim aligns with the specification, the patent is treated as essential. If any element is missing, or the claim contradicts the standard through conflicting requirements or descriptions, the patent is treated as non-essential. The check is made against all versions of HEVC, since the standard was improved in stages over time.
How do I request this report?
Requests go through the contact page of this website. Describe the portfolio or the questions you want answered and the team will respond with the details. Scope can be adjusted, so the analysis can be limited to selected HEVC areas, extended to more patents, or repeated for another company. The report is not downloaded from this page, since every request is handled directly.
