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 w.r.t 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 Orange HEVC report contain?
It contains an essentiality analysis of Orange’s patent portfolio against the HEVC/H.265 standard. Out of 51 identified patent families, 21 are classified as essential, 28 as non-essential and 2 as medium. The technical areas covered are block based coding, predictive coding, advanced intra and inter prediction enhancements, transformation and quantization, and filtering. Each patent was assessed by mapping the elements of its independent claims to the matching sections of the standard.
What does the medium classification mean?
Medium sits between the essential and non-essential outcomes. Essential means every element of the compared claim aligns with the H.265 specification. Non-essential means at least one element is missing from the standard, or the claim contradicts it through conflicting requirements or descriptions. Two of the 51 Orange families fall into the medium group, where the match is partial or depends on how a passage of the standard is read. Those cases are set out so your own counsel can judge them.
How was the initial dataset narrowed down?
An extensive search of patent databases produced an initial dataset of around 13k patents in the categories of interest. Relevance was then assessed from abstracts, summaries and claims with respect to H.265 technology, which included reading the claims, abstracts and detailed descriptions in each document. Searches combined search strings, IPC and CPC classifications, and HEVC specific keywords. What remained was the set of Orange families taken forward into the claim level essentiality review.
How is the report obtained?
It is supplied on request through the contact page. Reports are not sold through an online cart and there is no instant download, so a request opens a short discussion of what you need. Scope can be adjusted, for example by limiting the study to the prediction or filtering areas, by re-examining the families classified as medium in more depth, or by presenting the mapping in a claim chart layout that fits your review workflow.
