Description
To identify NXP’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.
We identified 93 unique and active NXP patent families potentially related to Wi-Fi 6 by manually reviewing bibliographic details of each patent family. It incorporates various advanced technologies like OFDMA, beamforming, MU-MIMO, BSS color, TWT, 160 MHz channel bandwidth, and multiple spatial streams to enhance speed, capacity, and efficiency.
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.
