Description
To identify Marvell’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 cover about Marvell and Wi-Fi 6?
It reviews Marvell’s patent portfolio in relation to Wi-Fi 6. A total of 56 unique and active patent families were identified. The analysis looks at the scope, relevance and potential essentiality of those families against key Wi-Fi 6 technologies such as OFDMA, MU-MIMO, beamforming, BSS color, spatial streams and Target Wake Time. Claims are read against the standard, so the report describes how the portfolio relates to Wi-Fi 6 rather than listing publication numbers.
Does the report include patents that are no longer in force?
No. The 56 patent families counted for Marvell are unique and active families, so families that are not active were not carried into the analysis. The search was also limited by priority date, covering only patents with a priority date on or before February 2021, when Wi-Fi 6 was published. Those two limits keep the set to filings that were live at the time of the study and that predate the published standard.
What does potentially essential mean in this analysis?
It means every element of the reviewed claim was found in the Wi-Fi 6 standard when a technical expert compared the two. Patents are classified as potentially essential, potentially non-essential, or medium. Potentially non-essential means an element is missing or conflicts with the standard, and medium sits between the two, where the mapping is not clear cut. Each classification reflects a manual reading of claim language against the text of the standard.
How can this analysis support licensing work?
It gives a claim level view of how one portfolio maps to Wi-Fi 6, which is the starting point for most licensing conversations. Teams use that view to prepare for negotiations, to test assertions made about a portfolio, or to plan freedom to operate and acquisition reviews. Because the classification criteria are set out in the report, the reasoning behind each result can be followed and challenged. Scope can be adjusted on request through the contact page.
