Description
To identify Mediatek’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 many Mediatek patent families relate to Wi-Fi 6 in this report?
A total of 71 unique and active patent families were identified for Mediatek in relation to Wi-Fi 6. The report examines the scope, relevance and potential essentiality of those families against key Wi-Fi 6 technologies, including OFDMA, MU-MIMO, beamforming, BSS color, spatial streams and Target Wake Time. Only patents with a priority date on or before February 2021, when the standard was published, were considered, so the set reflects work filed by that point.
Is the essentiality check done by hand or by software?
By hand. Each claim is analysed manually by a technical expert team with respect to the Wi-Fi 6 standard, to verify whether all claim elements are present. Search and filtering steps use databases, classifications and keywords, but the essentiality judgement itself rests on a reading of claim language against standard text. That reading produces the classification of potentially essential, potentially non-essential, or medium for each patent.
Which Wi-Fi 6 features were used to build the search?
Keywords 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 classifications used for filtering 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. Those terms and codes shaped the family set that was then reviewed claim by claim.
How do I get a copy?
Copies are provided on request through the contact page rather than as a download. Say which portfolio and which parts of Wi-Fi 6 matter to you, and the team will respond with what the report contains. Scope can be adjusted, so the same method can be applied to a narrower feature set or to another company’s portfolio. Requests are handled directly, so questions about method can be answered first.
