Description
We follow a 4-step process to extract a patent dataset specifically related to HEVC. Starting from thorough research of HEVC documents to the preparation of a detailed taxonomy, filtration of patents through CPCs, discussion dates, and other relevant search strings. Thereby, categorizing each patent based on its relevance and then extracting patent claims for further study.
By following this methodical approach, our team successfully prepared a portfolio comprising approximately 2000+ patents related to HEVC features.
To assess a patent’s essentiality, each claim is manually analyzed by our technical expert team with respect to the HEVC standard to verify whether all claim elements are present. We have classified a patent as potentially essential, potentially non-essential, or medium based on the following criteria:
- A patent is classified as potentially essential if claim elements align with the HEVC specifications.
- Conversely, the patent is classified as potentially non-essential if any element is missing or conflicts with the standard, such as contradictory requirements or descriptions.
- A patent is marked as medium if the main technical aspects are present in the HEVC standard, but some elements are not explicitly defined and can only be reasonably inferred from the identified sections.
Frequently asked questions
Which patents does this HEVC report analyse?
It analyses patents held with respect to the H.265 standard, better known as HEVC. Using a combination of relevant keywords and CPCs, more than 2000 distinct patent families related to HEVC were identified, and after in-depth analysis 2388 patents were shortlisted as exclusively related to HEVC. The analysis covers major HEVC technology areas including video coding, encoding, decoding, prediction, filtration, bitstream, 3D video coding, transformation and quantization, multi-layer video coding, block-based coding, CABAC and screen content coding.
How is the HEVC patent dataset built?
A four-step process is used. It starts with thorough research of HEVC documents, then the preparation of a detailed taxonomy, then filtration of patents through CPCs, discussion dates and other relevant search strings. Patents are then categorised by relevance and their claims extracted for further study. This produced a portfolio of approximately 2000 or more patents related to HEVC features. Each patent is then mapped, independent claim element by element, to the corresponding sections of the H.265 standard.
What do the essentiality classifications mean?
Each claim is analysed manually by the technical expert team against the HEVC standard to verify whether all claim elements are present. On that basis a patent is classified as potentially essential, potentially non-essential, or medium. Potentially essential means the claim elements map onto the standard, so practising HEVC would likely involve the patent. Potentially non-essential means that mapping fails. Medium sits between the two, where the evidence points both ways. These are technical opinions rather than legal rulings.
Who benefits from knowing who owns HEVC patents?
Licensing teams, companies shipping HEVC encoders or decoders, and IP counsel preparing negotiations all need an ownership picture grounded in claim level analysis. Portfolio owners also use this kind of study to benchmark their own position. The report is supplied on request through the contact page rather than sold online. Scope can be adjusted, so if you want particular technology areas, particular assignees, or a different level of claim detail, mention it when you request it.
