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
How many Google patents are analysed, and how were they found?
The report covers 65 active granted patents identified for Google that relate to HEVC technology. They were found through searches across multiple patent databases, using a combination of search strings, IPC and CPC classifications, and HEVC specific keywords. Results were then reviewed rather than accepted from the search alone. The patents that remained were evaluated by mapping the elements of their independent claims to the relevant sections of the H.265 standard, area by area.
What does essentiality mean in this report?
Essentiality means a claim cannot be avoided when implementing the standard, judged by comparing the claim with the specification text. Here the patented claim is compared to H.265, and if every element of the claim aligns with the specification, the patent is considered essential. If any element is not present, or the claim contradicts the standard, the patent is considered non-essential. Essentiality is checked with respect to all versions of HEVC, because features were introduced gradually over the life of the standard.
Which HEVC technology areas does the analysis cover?
The analysis covers Block-based coding, Predictive Coding, Transformation and Quantization, Multi-layer and Filtering. Those areas follow the main functional blocks of an HEVC encoder and decoder, so a reader can see which stage of the coding chain each Google patent touches. Grouping the portfolio this way also makes concentration visible, for example when a holder is strong in prediction but thin in filtering. Within each area, every patent keeps its own mapping to the relevant standard sections.
How can I get a copy of this report?
Request it through the contact page on the website and it will be shared with you. The report is delivered on request rather than through an online store, so there is no cart and no instant download. Scope can be adjusted before the work is sent. If you need a narrower set of technology areas, additional patents, or the same analysis applied to another HEVC portfolio, describe that requirement in your enquiry.
