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 Samsung and HEVC?
It covers an essentiality analysis of Samsung’s patent portfolio against the HEVC/H.265 standard. The study identified 139 active granted patents held by Samsung that relate to HEVC technology. The technical areas examined are block based coding, predictive coding, transformation and quantization, multi-layer coding, and filtering. Each patent was evaluated by mapping the elements of its independent claims to the relevant sections of the standard, which shows where the filings align with the specification.
What is a patent essentiality analysis?
It is a claim level comparison between a patent and a published technical standard. The question asked is whether a product that follows the standard would necessarily practise the claim. In this report the comparison is made against the H.265 specification, and a patent counts as essential only when every element of the claim aligns with that specification. Where an element is missing, or the claim contradicts the standard, the patent is treated as non-essential.
How were Samsung’s HEVC patents found?
Searches ran across multiple patent databases and combined search strings, IPC and CPC classifications, and keywords specific to HEVC. The results were screened down to active granted patents related to HEVC technology, which produced the set of 139 patents examined in the report. Each of those patents was then read, and its independent claim elements were compared with the text of the standard, area by area.
How can the report be obtained?
Request it through the contact page on the website. Reports are supplied on request, so there is no cart and no instant download, and a request starts with a short discussion of what you need. Scope can be adjusted, for example by narrowing the study to one technical area, by extending the review to further filings, or by presenting the claim to standard mapping in a format your licensing or litigation team already uses.
