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 Nokia and HEVC?
It is an essentiality analysis of Nokia’s patents against the HEVC/H.265 standard. A total of 75 active granted patents related to HEVC were identified for Nokia. Each patent was evaluated by manually mapping its independent claim elements to the relevant sections of the standard. The analysis covers block based coding, predictive coding, transformation and quantization, multi-layer and filtering, showing where Nokia’s work sits within high efficiency video coding.
What sources were used to find the patents?
Multiple patent databases were searched, using a combination of search strings, IPC and CPC classifications, and keywords specific to HEVC. The set was then narrowed to active granted patents related to HEVC technology. Each remaining patent moved to the claim mapping stage, where its independent claim was compared with the standard. Drawing on several databases helps capture members of the same family filed in different jurisdictions.
Which versions of HEVC is essentiality checked against?
All versions of the standard. HEVC was improved in stages as demands on video coding changed, so a claim may map to one release and not another. Checking against every version avoids a result that depends on which release was chosen. Within each version the test is the same: if all elements of a claim appear in the specification, the patent is treated as essential, and if an element is missing or conflicts, it is not.
How can I request this report?
Requests are made through the contact page of this website. Describe the portfolio and the questions you want the analysis to answer, and the team will reply with the details. Scope can be adjusted, so the study can be limited to selected HEVC areas or run for another company’s patents. Nothing is downloaded from this page, since each request is handled directly before the report is supplied.
