Description
To identify Apple’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
What does this assessment of Apple’s Wi-Fi 6 patents cover?
The report analyses Apple’s patent portfolio with respect to Wi-Fi 6. A total of 59 unique and active patent families were identified. The analysis addresses the scope, relevance and potential essentiality of those families in relation to key Wi-Fi 6 technologies, including OFDMA, MU-MIMO, beamforming, BSS color, spatial stream handling and Target Wake Time. Each claim is assessed against the text of the standard rather than judged by classification or keyword hits alone.
How were the relevant patents identified?
Searches were run across multiple patent databases using a combination of search strings, IPC and CPC classifications, and Wi-Fi 6 specific keywords. The keywords included OFDMA, Target Wake Time, BSS Color, High Efficiency, 802.11ax, 160 MHz, beamforming, spatial streams, 78.125 kHz, 1024-QAM, spatial reuse and Resource Unit allocation. CPC filters included H04W, H04W 84/12, H04W 72/04, H04W 72/12, H04W 52/02, H04W 52/36, H04W 88/08, H04B and H04B 7/06.
What do the essentiality classifications mean?
Each claim is manually analysed by the technical expert team against the Wi-Fi 6 standard to check 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 appear to be reflected in the standard. Potentially non essential means at least one element was not found there. The medium class covers cases that fall between those two outcomes.
Why is the search limited to a February 2021 priority date?
The Wi-Fi 6 standard was officially published in February 2021, so the search focused exclusively on patents with a priority date on or before that month. Filtering this way keeps the study to inventions that existed before the standard was published, which is the population that matters when testing whether claims track the standard. Only unique and active patent families were carried into the assessment.
