Manual Assessment of OFDMA Patent Portfolio in Relation to the Wi-Fi 6 Standard

Request this report

This report provides a detailed analysis of the OFDMA technology patent portfolio with respect to Wi-Fi 6.

To identify relevant patents, comprehensive searches were conducted across multiple patent databases using a combination of search strings, IPC/CPC classifications, and Wi-Fi 6 specific keywords. Since the Wi-Fi 6 standard was officially published in February 2021, the search focused exclusively on patents with a priority date on or before February 2021.

A total of 680 unique patent families were identified for OFDMA technology related to Wi-Fi 6. Out of these, 57 patent families were excluded from our analysis due to their inactive status. We also reviewed the family members of the excluded patents; some of them are still in the application phase, while others are inactive. Our analysis focused exclusively on active granted patents.

What you’ll get:

  • Essentiality analysis of OFDMA patent portfolio

  • Relevant independent claim

  • Target entity of independent claim

  • Patents that are potentially essential to Wi-Fi 6 standard

  • Patents that are potentially non-essential to Wi-Fi 6 standard

Description

To identify OFDMA patents relevant to Wi-Fi 6, we used keywords specifically associated with OFDMA in the context of Wi-Fi 6. The keywords are Orthogonal Frequency Division Multiple Access OFDMA, IEEE 802.11ax, Wi-Fi 6, resource Unit, RU, Subcarrier allocation, Tone plan, uplink/downlink OFDMA, etc.

This manual evaluation ensures that only patents aligned with the Wi-Fi 6 standard are labelled essential, with each claim thoroughly reviewed without reliance on AI algorithm.

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 this OFDMA report cover?
It covers the patent position around OFDMA technology as used in Wi-Fi 6, rather than the portfolio of a single company. A total of 680 unique patent families were identified for OFDMA in relation to Wi-Fi 6. Of those, 57 families were excluded because their status was inactive. Family members of the excluded patents were also reviewed, and some remain in the application phase while others are inactive. The analysis then focused on active granted patents.

How were the OFDMA patents found?
Searches ran across multiple patent databases using search strings, IPC and CPC classifications, and keywords specific to Wi-Fi 6. The OFDMA terms included Orthogonal Frequency Division Multiple Access, IEEE 802.11ax, Wi-Fi 6, Resource Unit, subcarrier allocation, tone plan, and uplink and downlink OFDMA. Because the standard was officially published in February 2021, the search was limited to patents with a priority date on or before that month.

How are patent families handled during the essentiality review?
One patent per family is analysed first. If that patent is found to be essential, the remaining members of the family are not evaluated, since the family is already represented in the essential set. If it is found to be non-essential, other patents within the same family are analysed to assess their essentiality. Every claim is reviewed by hand, without reliance on an AI algorithm, so only patents aligned with the Wi-Fi 6 standard are labelled essential.

How do I request this report?
Requests go through the contact page on the website. Reports are supplied on request rather than sold through an online cart, so you can describe what you need before anything is prepared. Scope can be adjusted, for example by narrowing the review to uplink or downlink OFDMA, by concentrating on resource unit and tone plan subject matter, or by extending the review across more members of each family. State the output format your team works with.
