Description
To identify International Semiconductor’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 report say about International Semiconductor’s Wi-Fi 6 portfolio?
It examines the scope, relevance and potential essentiality of International Semiconductor’s patents in relation to Wi-Fi 6. A total of 20 unique patent families were identified. The review looks at how those families relate to key Wi-Fi 6 technologies such as OFDMA, MU-MIMO, beamforming, BSS color, spatial streams and Target Wake Time. Each claim is read against the standard, so the output is a claim level assessment of the portfolio rather than a bibliographic listing.
Why does the search stop at a February 2021 priority date?
That date is tied to the standard itself, which was officially published in February 2021. The search therefore covered only patents with a priority date on or before that month. A priority date is the earliest filing date claimed by a patent family, so the cut off keeps the set anchored to work filed by the time the standard was published. The same rule was applied throughout, which makes the resulting family count consistent.
Which Wi-Fi 6 technologies does the analysis focus on?
Focus areas include OFDMA, MU-MIMO, beamforming, BSS color, spatial streams and Target Wake Time. Searches used matching keywords such as Orthogonal Frequency Division Multiple Access, Basic Service Set Color, High Efficiency, 802.11ax, 160 MHz, spatial reuse, 78.125 kHz, 1024-QAM 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. Those terms and classifications set the boundary of the search.
Who is this report written for?
It suits licensing teams, patent counsel and technical managers who need a view of one portfolio against Wi-Fi 6. Product and standards groups also use this kind of assessment when they map who holds patents around features they implement. The claim level classification supports work such as portfolio benchmarking, preparation for licensing talks and diligence on an acquisition. Anyone who needs a different cut of the same subject can ask for the scope to be adjusted.
