Description
To identify Wilus’ 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 many Wilus patent families are covered by this Wi-Fi 6 report?
The report covers 58 unique and active patent families identified for Wilus. Each was reviewed for scope, relevance, and potential essentiality against the Wi-Fi 6 standard. The technologies in focus include OFDMA, MU-MIMO, beamforming, BSS color, spatial streams, and target wake time. Because the review is manual, the result for each family rests on a reading of its claim elements against the text of the standard, not on classification codes or keyword hits, which served only to assemble the candidate set.
Which Wi-Fi 6 technologies does the analysis address?
The study is built around the features that separate Wi-Fi 6 from earlier versions of 802.11. Those include orthogonal frequency division multiple access, multi user MIMO, beamforming, basic service set color, spatial streams and spatial reuse, target wake time, high efficiency operation under 802.11ax, 160 MHz channels, 78.125 kHz subcarrier spacing, 1024-QAM, and resource unit allocation. The same terms served as search keywords when candidate patents were gathered from the patent databases.
How does the classification scheme work?
Each claim is analysed manually by the technical team with respect to the Wi-Fi 6 standard to verify whether all claim elements are present. A patent is classified as potentially essential when its claim elements align with the Wi-Fi 6 specifications. It is classified as potentially non-essential when an element is missing or conflicts with the standard, for instance through a contradictory requirement. A medium classification is used where the position is less clear, which keeps borderline cases visible instead of forcing them one way.
How can the report be requested?
Requests are made through the contact page on the website, and the report is supplied in response rather than downloaded from the page. Scope can be adjusted before delivery. A request might narrow the review to a few Wi-Fi 6 features, ask for the claim analysis behind particular families, or extend the same approach to another portfolio. Questions about the search strategy, the CPC filters, or the classification criteria can be raised in the same enquiry.
