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 the Huawei HEVC report contain?
It contains an essentiality analysis of Huawei’s patent portfolio against the HEVC/H.265 standard, covering 96 active granted patents identified as related to HEVC technology. Each patent was evaluated by mapping its independent claim elements to the relevant sections of the standard. The analysis is organised by technology area, covering Block-based coding, Predictive Coding, Transformation and Quantization, Multi-layer and Filtering, so the portfolio can be read one part of the coding chain at a time.
What sources were used to find the patents?
Searches were conducted across multiple patent databases, using a combination of search strings, IPC and CPC classifications, and HEVC specific keywords. The standard itself, H.265, is the reference text against which the claims are then compared. No single database was relied on alone, since jurisdiction coverage and family data differ between them. Results were narrowed to active granted patents related to HEVC technology before the manual claim mapping started, which is how the set of 96 patents was reached.
What decisions does this report support?
It supports licence negotiation, portfolio benchmarking, valuation and preparation for pool discussions, by showing where Huawei’s claims read on the H.265 standard. A licensing team can use the mapping to test a counterparty position. An acquirer can use it to judge how much of a portfolio actually touches the standard. Engineering and standards teams can use it to see which coding tools are covered. The findings are technical and are meant to inform commercial and legal work, not replace it.
Can the scope be adjusted, and how is the report obtained?
Yes, scope can be adjusted, and the report is supplied on request through the contact page on the website. There is no online purchase and no instant download. Say in the enquiry what you need, for example a subset of technology areas, a wider patent set, a family level view, or the same analysis run on another HEVC portfolio, and the work can be shaped around that. Each request is answered with the details of what will be delivered.
