MANUAL ASSESSMENT OF INTERDIGITAL's PATENT PORTFOLIO IN RELATION TO WI-FI 6 STANDARD
This report presents a comprehensive essentiality analysis of Interdigital’s patent portfolio with respect to the IEEE 802.11ax standard.
Using a combination of relevant keywords and CPCs, 41 distinct and active Interdigital patent families related to Wi-Fi 6 technologies were identified.
The analysis covered major Wi-Fi 6 technology areas, including OFDMA, MU-MIMO, beamforming, TWT, BSS color, spatial streams, and 160 MHz.
What you’ll get:
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.
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.
Below is an example of the analysis of one of Interdigital's patents:
