Wi-Fi 6/6E Patents: Who Leads, Where the Gaps Are 2026
- Filing has already peaked. annual filings rose to 403 in 2023 before easing back toward the low 20s in the still-incomplete 2026 count, with 2022's 340 marking the midpoint of a flattening curve.
- One assignee's pullback dominates recent momentum. LG Electronics filed 14 records in the latest year but that is an 86% YoY drop, while several Korean research and automotive players posted small absolute counts with 100-200% YoY increases.
- Claim density concentrates in two IPC subclasses. H04W (wireless communication networks) and H04L (digital transmission) cover 3,979 and 2,526 records respectively, against under 100 each in H04J, H04Q and H04M.
Filing growth compares 2021 (213 records) with 2024 (390) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 4,291 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This dataset tracks patent families filed against wireless LAN systems where the claims specifically address OFDMA scheduling, channel bonding, spatial stream allocation, interference mitigation or roaming — the technical mechanisms that separate Wi-Fi 6/6E implementations from earlier 802.11 generations. The search sits inside IPC classes H04W84, H04L27 and H04W72, which is why the composition below skews so heavily toward network architecture and digital transmission rather than pure RF hardware.
4,291 published families are captured from 2015 through the 2026-07-31 cut-off. Because publication typically lags filing by around 18 months, the 2025 and 2026 counts in any trend understate real filing activity for those years; treat the most recent two data points as provisional rather than as evidence of an actual slowdown.
Filing trend and technology composition
Two views of the same corpus: how filing volume has moved year over year, and which IPC subclasses carry the claim weight.
Annual filings, 2017-2026
Filings climbed from 223 in 2017 to a peak of 403 in 2023, crossed the 2022 midpoint at 340, and have since fallen back sharply — though the 2025-2026 figures are still filling in as later publications land.
IPC subclass distribution
H04W and H04L together account for the large majority of records, confirming that claim activity centers on network-layer coordination (scheduling, access, roaming) rather than on the physical transmission hardware covered by H04B, H04J or H03M.
Shares are the percentage of the 4,291 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Three read-throughs from the trend, composition and citation data that matter for anyone deciding where to file next.
The wave has crested, publication lag aside
Annual filings rose steadily from 223 in 2017 to 403 in 2023, then fell back through 2022's 340 midpoint toward the low 20s recorded so far in 2026. Even allowing for the 18-month publication lag understating the last two years, the shape is a mature filing wave rather than an emerging one.
Network-layer coordination is the crowded ground
H04W and H04L cover the bulk of filings, meaning OFDMA scheduling, access-point coordination and roaming logic are the most densely claimed mechanisms in this dataset. Physical-layer subclasses like H04B, H04J and H03M carry a fraction of the volume.
The leading filer is pulling back while smaller players tick up
LG Electronics still posted the highest absolute count in the latest year at 14, but that is an 86% drop from the year before. Meanwhile Korean research bodies and Sony recorded small absolute increases of 100-200% YoY, though off a low base.
Foundational patents predate the Wi-Fi 6/6E naming era
The most-cited records in this corpus, including US5796727A and US6600734B1, date from the early wireless-LAN era and address access architecture and AP-selection roaming rather than OFDMA. High citation counts here mark influence on later filings, not current claim relevance.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to wi-fi 6/6e and wireless lan systems, with the prior art for and against each one.
Who is filing, and where the gate sits
Filing activity concentrates among a small set of Korean electronics, automotive and research entities, with co-filing patterns pointing at specific industry-academia partnerships.
LG Electronics
Still the largest single filer by latest-year volume, but the sharp YoY drop suggests this assignee's core Wi-Fi 6/6E claim positions are largely staked out already.
Korean research–university–automotive ties
The Electronics and Telecommunications Research Institute and Korea National University of Transportation's technology transfer arm co-file most heavily, with further pairs linking the university to Hyundai and Kia — pointing to a connected-vehicle Wi-Fi research cluster.
Research institutes gaining share off a low base
Both organisations moved from a single-digit prior-year count to 3 filings in the latest year — a large percentage jump, but still a small absolute footprint compared to the corporate leaders.
Some large filers have gone quiet in this specific claim space
Samsung recorded zero filings in the latest year (-100% YoY) and Huawei just one (-67% YoY) within this specific OFDMA/channel-bonding/roaming claim set, even though both remain active wireless filers more broadly.
| Assignee | Recent year | YoY |
|---|---|---|
| LG Electronics | 14 | -86% |
| Electronics and Telecommunications Research Institute (ETRI) | 3 | +200% |
| Korea National University of Transportation Industry-Academic Cooperation Foundation | 3 | +200% |
| Sony Group Corporation | 2 | +100% |
| Huawei Technologies Co., Ltd. | 1 | -67% |
| Samsung Electronics Co., Ltd. | 0 | -100% |

Where to take this analysis
The trend and assignee data point to specific next questions for teams evaluating freedom-to-operate or new filing positions in this space.
Map the white space claims in detail
The under-claimed sub-areas identified here — multi-AP spatial stream coordination, cross-band roaming signalling — warrant a claim-by-claim review before drafting, since density figures alone don't confirm an area is open.

The Korean research-university-automotive filing pattern suggests a connected-vehicle Wi-Fi push; watching this cluster's next filings could flag where automotive WLAN standards are heading.
Monitor assignee activity in EurekaRe-run the query as later filings publish
Given the 18-month publication lag, the 2025-2026 filing counts will continue to rise for at least another year; a follow-up pull will sharpen whether the 2023 peak was truly the top of the cycle.
Set up a filing alert in EurekaCommon questions about Wi-Fi 6/6E patents
Within this dataset, LG Electronics is the most active recent filer by absolute count, though its latest-year volume is down sharply (-86% YoY) from the prior year. Samsung Electronics and Huawei both hold substantial historical filing positions but showed little to no new filing activity in the latest year within this specific OFDMA, channel-bonding and roaming claim set. A full freedom-to-operate view should also weight older foundational patents like US5796727A and US6600734B1, which are heavily cited despite predating the Wi-Fi 6/6E naming era.
No — filings rose from 223 in 2017 to a peak of 403 in 2023, then declined toward the low 20s recorded so far in 2026. Because patent publication typically lags actual filing by around 18 months, the 2025 and 2026 figures will rise as more records publish, but the overall shape already looks like a mature filing wave rather than an accelerating one. Anyone using this trend to size opportunity should treat the most recent two years as provisional.
This landscape is built on IPC classes H04W84 (wireless communication network architecture), H04L27 (modulation/demodulation for digital transmission) and H04W72 (resource allocation in wireless networks), which is why H04W and H04L dominate the composition data with 3,979 and 2,526 records respectively. Smaller volumes appear in H04B (transmission hardware), H04J (multiplex communication) and H03M (coding), indicating the claim activity in this space is concentrated at the network coordination layer rather than the physical layer.
The composition data shows heavy claim density in H04W and H04L subclasses covering core OFDMA scheduling and access coordination, but comparatively thin coverage in specific adjacent mechanisms such as multi-AP coordinated spatial stream allocation, cross-band roaming handoff signalling, and dynamic channel-bonding fallback under interference. These are candidate areas for new claims, though a density gap should always be confirmed against a claim-by-claim review before drafting, since low volume can also mean a technique isn't commercially viable rather than that it's unclaimed.
US10211890B2, assigned to LG Electronics and granted in February 2019, claims a method where an access point generates a MIMO-OFDMA format PPDU comprising multiple sub-channel PPDUs synchronized in time phase, then transmits them to different stations over separate sub-channel bands, with training field counts sized to the number of MIMO streams involved. This is a specific implementation of combined MIMO and OFDMA downlink transmission, so it primarily constrains AP-side scheduling and framing designs that use this exact sub-channel synchronization approach rather than OFDMA or MIMO generally.
