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
Which Toshiba patents does this HEVC analysis include?
The analysis covers 68 active granted patents identified for Toshiba as related to HEVC technology. They were reached through searches across multiple patent databases using search strings, IPC and CPC classifications, and keywords specific to HEVC. The set spans block based coding, predictive coding, transformation and quantization, multi layer coding, and filtering. Each patent then went through a manual mapping of its independent claim elements against the relevant sections of the H.265 standard, and the outcome of that mapping is reported.
What does the claim to standard mapping show?
The mapping shows, for each patent, which sections of H.265 its independent claim elements correspond to. Read across the portfolio, it indicates where the filings concentrate within the standard and how closely each one tracks the specification text. That is more informative than a count of patents, because two portfolios of similar size can sit at very different distances from the parts of the standard an implementer actually has to build.
How is an essential patent distinguished from a non-essential one?
A claim is compared with the H.265 standard element by element. If every element of the claim aligns with the specification, the patent is considered essential, since the standard cannot be implemented without it. If any element is absent, or the claim contradicts the standard through conflicting requirements or descriptions, the patent is considered non-essential. Essentiality is checked against all versions of HEVC, because the standard was extended over time and a claim may align with one version only.
How do I request this report?
Send an enquiry through the contact page on the website and the report will be supplied in response. Nothing is downloaded from the product page itself. Scope can be adjusted before delivery, so a request may narrow the study to one HEVC technology area, ask for more of the claim analysis behind particular patents, or apply the same method to a different portfolio. Questions about the search strategy or the assessment criteria can be answered at that point.
