V2X Communication Patents: Top Companies & Filing Trends 2026
- Filing has cooled since 2019. The peak year for V2X filings was 2019 at 436 records; by the most recent full year, volume has fallen well below that level, with 2026 still partial.
- One IPC subclass dominates claim scope. H04W (wireless communication networks) appears in 2,212 of 2,351 records — almost every filing anchors its claims there, leaving H04L, G08G and smaller subclasses as secondary battlegrounds.
- Momentum is pulling back across the board. The leading assignee filed 6 in the latest year, down 60% year-on-year, while several other major filers dropped to zero — a signal the field is consolidating rather than expanding.
Filing growth compares 2021 (320 records) with 2024 (104) — 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 2,351 records in scope (CR5), not by the ranked leaders only.
What the V2X patent record actually shows
Vehicle-to-Everything communication sits at the intersection of cellular standards work and traffic-system engineering. The corpus behind this page — 2,351 patent families published between 2015 and mid-2026 — is built from claims that reference latency requirements, message sets, security credential management, DSRC coexistence or roadside units, filtered to the wireless-networking and traffic-control IPC classes. That combination captures the practical engineering layer of V2X rather than the broader connected-vehicle marketing category.
Filing activity rose sharply through the late 2010s as cellular V2X (C-V2X) standardisation work at 3GPP intersected with early roadside-unit deployments, peaked in 2019, and has since declined. Because publication typically lags filing by around 18 months, the last one to two years in any trend chart understate real activity — but the shape of the decline from 2019 onward predates that lag window and reflects a genuine slowdown in new filing.

Filing trend and technology composition
Two views of the same 2,351-family corpus: how filing volume has moved year over year, and which IPC subclasses carry the claim weight.
Filing trend
Filings ran 224 in 2017, rose to a peak of 436 in 2019, and by the 2022 midpoint sat at 318 — already below peak. The trajectory to 2026 (partial, 14 records) is a flat-to-declining line, not a growth curve.
IPC composition
H04W (wireless communication networks) covers 2,212 of 2,351 records, with H04L (digital information transmission) a distant second at 779 and G08G (traffic control systems) at 410. B60W, G01S, G06F and G07C each cover under 100 records — these are the peripheral classes where V2X claims touch vehicle control, positioning, data processing and access control.
Shares are the percentage of the 2,351 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

US20190110177A1 — resource selection within a latency requirement
The present invention provides a vehicle-to-X (V2X) operation method performed by a V2X terminal in a wireless communication system, the method comprising: selecting a resource to be used for performing a V2X communication within a range satisfying a latency requirement; and performing a V2X communication on the basis of the selected resource.Filed by LG Electronics, published 2019-04-11 — a resource-selection method built explicitly around meeting a latency bound, a claim shape that recurs across the most-cited records in this corpus.

Three read-throughs from the corpus that matter more for strategy than the raw counts do on their own.
The highest-value claim territory is already staked
The single most-cited record, on high-reliability V2X transmission, carries 501 citations — more than double the next entry. Records built on resource selection and reliability sit at the centre of the citation graph, meaning new filings in that exact claim shape face the densest prior art.
Filing is US-weighted but not US-exclusive
The United States receives more than double the filings of the EPO and over five times China's count in this dataset. WIPO/PCT filings (153) and India (143) show the technology is being routed for multi-jurisdiction protection rather than filed as a single-market play.
Most filings are single-assignee, not joint ventures
Only 10 co-assignee pairs surface in the corpus, and the strongest of those links one major filer to individual named inventors rather than to another corporate assignee. Cross-company joint filing is the exception here, not the norm.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to vehicle-to-everything (v2x) communication, with the prior art for and against each one.
Assignee landscape and where the gaps sit
Filing volume concentrates at the top of the ranking, but the momentum data tells a different story: nearly every major name has pulled back in the latest year, not just the smaller filers.
Even the top filer is decelerating
The leading assignee still filed more than any other name in the latest year, but its own volume fell 60% year-on-year — a pullback, not a pause, given the size of the drop relative to prior activity.
Several large filers stopped filing entirely in the latest year
LG Electronics, Huawei, Samsung and Toyota each recorded zero filings in the most recent year after prior activity — consistent with core V2X claim territory being viewed internally as settled rather than still open.
A long tail of single-filing entrants sits below the concentrated top
Regional research institutes and vehicle-electronics specialists appear as single or low-count filers rather than repeat filers, suggesting narrower, defensive filings rather than sustained R&D programmes in this claim space.

Where to take this analysis
The dataset points to a field consolidating around resource-selection and reliability claims while several adjacent branches stay thin. Two directions follow from that.
Map your own claim draft against the cited core
Before drafting around latency requirements or resource selection, check how closely your language sits to the most-cited records in this corpus — that claim shape is the most densely covered in the dataset.
Run a claim comparison in EurekaTest the under-claimed branches for freedom to operate
Security credential management and DSRC coexistence show materially lower record counts than core wireless-networking claims — worth a dedicated freedom-to-operate pass before committing R&D spend there.

Filing in this corpus is concentrated at the top of the assignee ranking, with a small number of large telecom and automotive electronics firms accounting for a disproportionate share of the 2,351 families tracked. That said, momentum has shifted: several of the largest historical filers, including LG Electronics, Huawei, Samsung and Toyota, recorded zero filings in the most recent full year, while the current volume leader is itself down 60% year-on-year. Ranking by cumulative count and ranking by recent activity point to different companies, so it matters which question you're actually asking.
No — filing peaked in 2019 at 436 records and has declined since, with the 2022 midpoint already down to 318. Because publication lags filing by roughly 18 months, the final one to two years in any dataset understate true activity, but the multi-year decline from the 2019 peak predates that lag and reflects a genuine slowdown rather than a reporting artefact. This pattern is typical of a field where core claim territory has been substantially staked and standardisation work has matured.
The overwhelming majority of records, 2,212 out of 2,351, touch IPC subclass H04W for wireless communication networks, with H04L (digital information transmission) and G08G (traffic control systems) as secondary but still substantial categories. Smaller overlaps appear in B60W (vehicle control), G01S (radar and positioning), G06F (data processing) and G07C (checking devices) — these peripheral classes are where V2X claims intersect with vehicle dynamics, sensor fusion and access control, and tend to carry lower filing density.
US20190110177A1, filed by LG Electronics and published in April 2019, claims a method for a V2X terminal to select a communication resource that satisfies a defined latency requirement, then perform the V2X communication using that resource. The claim ties resource selection directly to a latency bound rather than claiming latency reduction generally, which narrows its scope but also makes it a frequently cited reference point for anyone drafting resource-selection claims in cellular V2X. It is one of several highly cited records in this corpus built around the same resource-selection-under-latency-constraint claim shape.
The IPC composition data shows security credential management, DSRC-to-cellular-V2X coexistence, and roadside-unit hardware architecture all carry materially lower record counts than the core wireless-networking claims that dominate the corpus. Radar-assisted positioning fusion and joint vehicle-control message sets, which overlap with G01S and B60W respectively, also show thinner coverage relative to H04W. These are not guaranteed to be free of prior art, but they are the branches where filing density is lowest relative to the technology's overall footprint, making them worth a dedicated freedom-to-operate check before committing to a claim strategy there.
