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.
Frequently asked questions
What does the NXP Wi-Fi 6 report analyse?
It analyses NXP’s patent portfolio against the Wi-Fi 6 standard. The study identified 93 unique and active NXP patent families related to Wi-Fi 6 technologies. Mapping covers areas such as OFDMA and MU-MIMO, along with beamforming, BSS color, Target Wake Time, 160 MHz channel bandwidth and multiple spatial streams. These are the features that raise speed, capacity and efficiency in Wi-Fi 6 networks. The report shows where the identified filings sit against those parts of the standard.
Why does the search stop at a February 2021 priority date?
Because the Wi-Fi 6 standard was officially published in February 2021. The search was therefore limited to patents with a priority date on or before that month, which keeps the set to filings that could read on the published standard. Later filings fall outside the window and were not included. The cutoff is applied consistently across the search, so the family count follows one clear rule rather than a mix of dates.
Which keywords and classification codes were used in the search?
Search terms covered Wi-Fi 6 features by name, including 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. Filtering used CPC codes including H04W, H04W 84/12, H04W 72/04, H04W 72/12, H04W 52/02, H04W 52/36, H04W 88/08, H04B and H04B 7/06. Bibliographic details of each family were then reviewed by hand.
Who uses a report like this?
Licensing teams, patent counsel and technology strategists use it. The family level view supports licensing discussions, portfolio benchmarking, clearance analysis and acquisition screening in the Wi-Fi 6 space. Product and standards teams also read it to see which parts of 802.11ax are most heavily patented by a single filer. Because each conclusion traces back to a claim and a section of the standard, the findings can be checked by your own experts before you act on them.
