Description
To identify Qualcomm’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. Using this approach, we identified 300 unique Qualcomm patent families potentially related to Wi-Fi 6 by manually reviewing the bibliographic details of each patent family.
The manual evaluation ensures that only patents aligned with the Wi-Fi 6 standard are labelled essential, with each claim thoroughly reviewed without reliance on an AI algorithm. We have analysed one patent per family. If that patent is found to be essential, we did not evaluate the remaining family members. However, if it is found to be non-essential, we analysed other patents within the same family to assess their essentiality.
Frequently asked questions
What does the Qualcomm Wi-Fi 6 report cover?
It covers an essentiality analysis of Qualcomm’s patent portfolio against the IEEE 802.11ax standard. The report works with the Qualcomm patent families identified as related to Wi-Fi 6 technologies through a search-string, keyword and CPC screen. The focus is the scope, relevance and potential essentiality of the portfolio in relation to key Wi-Fi 6 technologies, including OFDMA, MU-MIMO, beamforming, BSS color, Target Wake Time and spatial streams.
How were the families screened before the claim review?
Screening combined search strings, Wi-Fi 6 keywords and CPC codes. The keyword set covered Orthogonal Frequency Division Multiple Access, Target Wake Time, Basic Service Set Color, High Efficiency, 802.11ax, 160 MHz, beamforming, spatial streams, 78.125 kHz, 1024-QAM, spatial reuse and Resource Unit allocation. CPC filtering used codes including H04W, H04W 84/12, H04W 72/04, H04W 72/12, H04W 52/02, H04W 52/36, H04W 88/08, H04B and H04B 7/06. Bibliographic details of each family were reviewed by hand before any claim mapping began.
How is a patent labelled essential here?
A claim is compared with the Wi-Fi 6 standard, and the patent is labelled essential only when the claim aligns with the standard. Every claim is reviewed by a person, without reliance on an AI algorithm, so a label reflects a reasoned reading rather than a similarity score. One patent per family is analysed first. If it is essential the other members are not evaluated, and if it is non-essential other patents in the family are examined.
Who is this report for?
Licensing and patent teams that deal with Wi-Fi 6 are the main readers. The family level view supports licence negotiation, portfolio benchmarking, pool discussions and diligence on wireless assets. Product and standards engineers use it to see which parts of 802.11ax carry the heaviest patent activity for one filer. Since every conclusion points to a claim and a part of the standard, an internal team can verify the mapping before a commercial position is taken.
