HEVC ESSENTIALITY REPORT
HEVC (high-efficiency video coding), also known as H.265, is a video compression standard that exemplifies the power of global collaboration. It signifies a substantial advancement in video compression technology, enabling the efficient delivery of high-quality video.
The filing of video coding patents peaked between 2011 and 2013, coinciding with a surge in technological advancements that culminated in the finalization of the H.265 standard.
The impact of these patents on the HEVC standard is significant, as they provide the foundation for essential video coding processes that facilitate higher compression rates, reduce storage requirements, and enhance streaming capabilities.
This analysis underscores the importance of the HEVC standard and provides a roadmap for future exploration of patent trends and their impact on the video coding industry.
This report aims to offer a comprehensive overview of the HEVC patent landscape, examining essentiality to determine if a patent is crucial for implementing the standard. Although the HEVC standard was finalized in 2013, improvements have been gradually introduced to meet evolving technological demands.
Subsequent editions have added features such as 3D video support, screen content coding, and neural network post-processing, ensuring HEVC’s adaptability and relevance. This iterative approach has enabled the standard to address the diverse needs of applications over time. The next section delves into these editions and their contributions to expanding HEVC’s functionality and impact.
The report's scope is to identify and analyze all patents with a priority date before April 13, 2013, that are essential to the HEVC standard. It is likely that patents with a priority date after April 13, 2013, are essential to some versions of HEVC; however, the scope of this report is limited and does not consider patents with a priority date after April 13, 2013. Patents having a priority date earlier than April 13, 2013 and filing date later than April 13, 2013 were considered for essentiality analysis.
This report presents a comprehensive analysis of the HEVC patent landscape as it relates to the H.265 standard, highlighting both the technical innovation and the competitive positioning of key stakeholders. An extensive search of patent databases yielded an initial dataset of over 9,000 patents in our areas of interest. This extracted dataset has a priority date before the publication date of the first version of HEVC, April 13, 2013.
To determine the essentiality of a patent, each claim is analyzed with H.265 versions of the standard to identify whether the elements of the patented claim are present in the standard. Essentiality is assessed concerning all versions of HEVC, as improvements have been gradually implemented to address evolving technological demands. Subsequent editions introduced enhancements such as 3D video support, screen content coding, and neural network post-processing, ensuring HEVC’s adaptability and relevance.
The 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. Conversely, if any element is absent or there is a contradiction between the claim and the standard (for instance, conflicting requirements or descriptions), the patent is deemed non-essential. This manual evaluation ensures that only patents fully aligned with the H.265 standard's requirements are classified as essential.
The filing trend for HEVC patents reveals significant variations over the years. There was minimal activity in 2010, followed by a rise in 2011. Patent filings surged notably in 2012 and 2013.
A detailed analysis was performed on 178 patents assigned to NPEs to identify the assignees who transferred their assets to NPEs. The top 10 NPEs were determined based on the number of patents reassigned to them. Access Advance HEVC patent pool provides streamlined access to essential intellectual property (IP) for standardized technologies.
