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 show about Ericsson’s HEVC portfolio?
It presents an essentiality analysis of Ericsson’s patents against the HEVC/H.265 standard. The study identified 24 active granted patents for Ericsson that are related to HEVC technology. Each one was evaluated by mapping its independent claim elements to the relevant sections of the standard, so a reader can see where the claims align with the specification. The work covers the main HEVC technology areas, including Block-based coding, Predictive Coding, Transformation and Quantization, Multi-layer and Filtering.
Are all versions of HEVC considered?
Yes. Essentiality is checked with respect to all versions of HEVC, because improvements were implemented gradually to address evolving technical demands. A claim that does not read on an early release may read on a later one, so checking a single version would give an incomplete picture. Each Ericsson patent is therefore compared against the H.265 text across versions, and the mapping records the sections that the claim elements match. This also makes the result easier to reuse as the standard evolves.
What makes a patent non-essential in this analysis?
A patent is treated as non-essential when at least one element of the claim is not present in the standard, or when the claim contradicts the standard, for example through conflicting requirements or descriptions. Essential means the opposite, that every element of the claim aligns with the H.265 specification. The judgement is technical and rests on a manual reading of the claim against the standard text. It reflects the analysis set out in this report and is not a legal opinion.
How do I request the report and can the scope be changed?
Send a request through the contact page on the website and the report will be shared with you. It is not sold through an online checkout and there is no instant download. Scope can be adjusted before the work is delivered. If you need a different set of technology areas, a wider or narrower patent set, or a comparison against another HEVC portfolio, describe the requirement in your enquiry and the analysis can be shaped to match it.
