Description
To identify Huawei’s patents related to Wi-Fi 6, we employed Wi-Fi 6 relevant keywords such as Orthogonal Frequency Division Multiple Access (OFDMA), Target Wake Time (TWT), Basic Service Set (BSS) Color, High-Efficiency (HE), 802.11ax, 160 MHz, beamforming, spatial streams, 78.125 kHz, 1024-QAM, spatial reuse, Resource Unit (RU) allocation, etc. The CPCs used for filtering included H04W, H04W 84/12, H04W 72/04, H04W 72/12, H04W 52/02, H04W 52/36, H04W 88/08, H04B, H04B 7/06, etc.
To assess a patent’s essentiality, each claim is manually analysed by our technical expert team with respect to the Wi-Fi 6 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 Wi-Fi 6 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 Wi-Fi 6 standard, but some elements are not explicitly defined and can only be reasonably inferred from the identified sections.
Frequently asked questions
How large is the Huawei portfolio covered by this Wi-Fi 6 report?
A total of 259 unique patent families were identified for Huawei in relation to Wi-Fi 6. The set was built through searches across multiple patent databases, using search strings, IPC and CPC classifications, and Wi-Fi 6 specific keywords, limited to patents with a priority date on or before February 2021. That is the month in which the Wi-Fi 6 standard was officially published. The report assesses the scope, relevance and potential essentiality of the identified families.
Which Wi-Fi 6 features are the focus of the analysis?
The analysis focuses on key Wi-Fi 6 technologies, including OFDMA, MU-MIMO, beamforming, BSS color, Target Wake Time and spatial streams. These are the features that separate Wi-Fi 6 from earlier releases, so they are where essential patents are most likely to sit. Search keywords also covered High-Efficiency, 802.11ax, 160 MHz, 78.125 kHz, 1024-QAM, spatial reuse and Resource Unit allocation, which helped bring in patents that describe the same features in different words.
What does the medium classification mean?
Patents are classified as potentially essential, potentially non-essential, or medium. Potentially essential means the claim elements align with the Wi-Fi 6 specifications. Potentially non-essential means an element is missing or conflicts with the standard. Medium sits between the two and marks a patent where the reading is not clear, for example where a claim element is arguable against the specification text. Keeping that middle group separate avoids forcing an uncertain case into either result and shows where closer review is worthwhile.
How do I request this report?
Ask for it through the contact page on the website. The report is provided on request, so there is no cart and no instant download, and an enquiry is answered with the details of what will be supplied. Scope can be adjusted. With a set of this size, many readers ask for a narrower cut, such as a single Wi-Fi 6 feature, one jurisdiction, or only the families classified as potentially essential. Describe what you need in the enquiry.
