Description
To identify LG’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
How many LG patent families does this Wi-Fi 6 report cover?
A total of 254 unique patent families were identified for LG in relation to Wi-Fi 6. Each was found through searches across multiple patent databases and then reviewed for scope, relevance and potential essentiality. The review looks at key Wi-Fi 6 technologies such as OFDMA, MU-MIMO, beamforming, BSS color, spatial streams and Target Wake Time. Only patents with a priority date on or before February 2021, when the standard was published, were included.
What search terms and classifications were used?
Searches combined search strings, IPC and CPC classifications, and Wi-Fi 6 specific keywords. Keywords included 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. CPC filters included H04W, H04W 84/12, H04W 72/04, H04W 72/12, H04W 52/02, H04W 52/36, H04W 88/08, H04B and H04B 7/06. Several databases were used so that families filed in different jurisdictions were captured.
How is essentiality decided for each patent?
Each claim is analysed manually by a technical team against the Wi-Fi 6 standard to verify whether all claim elements are present. On that basis a patent is classified as potentially essential, potentially non-essential, or medium. The word potentially is used because essentiality is a judgement about the mapping between claim language and standard text, and courts or patent pools may reach their own view. The reading is done claim by claim rather than by keyword matching.
Can the scope of this report be adjusted?
Yes. The report is available on request through the contact page, and the scope can be shaped around what you need. Options include narrowing the review to particular Wi-Fi 6 features, focusing on a subset of the 254 families, or applying the same method to another portfolio or another standard. Describe the question you want answered when you get in touch, and the team will confirm what the work would involve.
