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 is covered in the Texas Instruments HEVC report?
It is an essentiality analysis of the Texas Instruments portfolio with respect to the HEVC/H.265 standard, built on 73 active granted patents identified as related to HEVC technology. Coverage spans block based coding, predictive coding, transformation and quantization, multi layer coding, and filtering. Each patent was evaluated by manually mapping its independent claim elements to the relevant sections of the standard, so every finding can be traced to a specific part of H.265 rather than resting on classification data alone.
How does a manual claim mapping differ from an automated search?
Manual mapping puts a technical reviewer between the claim and the standard. Each independent claim is read element by element and compared with the sections of H.265 that describe the same function. Wording rarely matches exactly, so judgement is needed to decide whether a claim element is genuinely present in the specification. A keyword or classification search can surface candidate patents quickly, but it cannot make that call, which is why the assessment in this report is carried out by hand.
Who is this report intended for?
It suits licensing and IP teams that need to understand a third party HEVC portfolio before entering a negotiation, implementers checking their exposure to H.265 patents, and analysts reviewing portfolio strength. The claim level mapping gives each group a documented basis for its own conclusions. Copies are supplied on request through the contact page, and scope can be adjusted, for example to focus on a single technology area or on a shorter list of patents.
