- Concentration at the top. The five leading assignees hold 51.6% of all 5,487 records in scope, and the top ten hold 64.6% — this is a field with a short, dominant list of filers rather than a broad field of small players.
- Filing kept climbing through 2024. Volume rose from 682 records in 2021 to 791 in 2024, a 16% increase, after peaking at 869 in 2022 — the most recent two years understate true activity because publication lags filing by roughly 18 months.
- Wireless framing dominates the claim language. 64.0% of records sit in H04W (wireless communication networks) and 27.6% in H04L (digital transmission), while traffic control (G08G) and positioning (G01S) each cover under 14% of the same record set.

Filing growth compares 2021 (682 records) with 2024 (791) — 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 5,487 records in scope (CR5), not by the ranked leaders only.

Overview
What this landscape covers
This dataset tracks patent filings at the intersection of roadside infrastructure and vehicle-facing sensing: roadside units, roadside sensors and infrastructure-to-vehicle links, searched jointly against hardware and deployment concerns such as antenna placement, backhaul links, line of sight, edge computing nodes, sensor calibration and power supply. It spans 5,487 published records filed between 2015 and mid-2026, giving a working view of how communications, positioning and traffic-control disciplines converge on physical roadside hardware.
The record set is dominated by mobile-communications specialists rather than traditional traffic-infrastructure vendors, which shapes where the claim density sits: wireless protocol and transmission classes carry far more filings than the traffic-control or positioning classes that describe the roadside use case itself. That gap is where a landscape review earns its keep — it separates occupied claim space from areas still open to a first filing.

The Data
Filing trends and technology composition
Two views of the same 5,487-record set: how filing volume has moved year over year, and how those records classify across IPC subclasses. Because a single record can carry several IPC codes, the class shares below add up to more than 100% of the record total.
Filing trend, 2017-2026
Annual filings rose from 159 in 2017 to a peak of 869 in 2022, then continued at a high level, with 682 records in 2021 growing to 791 in 2024 — a 16% rise over that three-year span. The 2025 and 2026 figures (2026 partial) will revise upward as publication catches up with filing.
IPC subclass composition
H04W (wireless communication networks) covers 64.0% of all 5,487 records and H04L (digital transmission) covers 27.6%, confirming that most of this claim space is written as communications art. G08G (traffic control) at 13.8% and G01S (radar, sonar and positioning) at 12.9% mark the smaller but more infrastructure-specific slice of the field, with B60W, G06F and G05D trailing further behind.
Shares are the percentage of the 5,487 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

What the numbers say
Three patterns stand out once filing trend, assignee concentration and technology composition are read together.
Concentration
51.6%
of 5,487 records held by top 5 assignees
A short list of firms sets the terms
With the five leading assignees holding 51.6% of all records in scope and the top ten holding 64.6%, most of the claim space in roadside unit hardware has already been staked out by a small group of communications-equipment filers rather than a broad field of infrastructure vendors.
Top 10 combined: 3,544 records
Momentum
+16%
filing growth, 2021 to 2024
Growth held through the last complete year
Filing volume grew from 682 records in 2021 to 791 in 2024, a 16% increase, after an early peak of 869 in 2022. Readings for 2025 and 2026 are still incomplete because publication trails filing by roughly 18 months, so the apparent recent dip should not be read as a slowdown.
Peak year: 2022 at 869 records
Composition
64.0% / 13.8%
H04W share vs. G08G share of 5,487 records
Communications art outweighs traffic-control art
H04W and H04L together touch the large majority of records, while G08G (traffic control systems) and G01S (radar, sonar and positioning) — the classes closest to the physical roadside sensing problem — cover markedly smaller shares of the same set, pointing to where infrastructure-specific claims remain comparatively thin.
G01S share: 12.9% of records

Players
Who is filing, and how fast
The ranked leaders in this dataset skew toward mobile-communications and chipset firms rather than dedicated roadside-infrastructure suppliers, which explains why recent-year momentum is falling sharply even among the largest filers.
Leader
1,605
records
A single filer well ahead of the field
The leading assignee holds 1,605 records, well clear of the fifth-place filer at 262 and the tenth-place filer at 117 — a steep drop-off that marks this as a leader-and-field structure rather than an evenly spread market.
Fifth place: 262 records · Tenth place: 117 records
Momentum
-78% YoY
latest-year change, top filer
Recent-year filings are down across the largest assignees
The leading assignee filed 43 records in the latest year, down 78% year over year, and every other tracked assignee in the momentum list also shows a decline or flat filing count. Because publication lags filing by about 18 months, part of this apparent drop is a reporting artefact rather than a real pullback.
Second-ranked filer: 13 records, -86% YoY
Collaboration
10
co-assignee pairs tracked
Co-filing is concentrated around a few chipset partnerships
Only ten co-assignee pairs appear in the data, and the strongest pairs cluster around a small number of chipset and standards-essential-patent specialists filing jointly with named inventors or affiliated entities, rather than broad cross-industry collaboration.
Strongest pair: 71 shared records

What's Next
Where to take this
The dataset points to a field where communications giants hold the broad claim space and infrastructure-specific art is thinner. Two directions follow from that.
Check the under-claimed branches before drafting
Sensor calibration, edge-node handover and power-supply resilience for roadside hardware show materially less filing density than the wireless-protocol classes. A first claim there has more room to stand on its own.
Explore white space in EurekaWatch the leader's momentum, not just its stock
The leading assignee's sharp year-over-year drop is partly a publication-lag artefact, but it is worth tracking whether the next complete filing year confirms a real slowdown or a return to the 2021-2024 growth rate.

FAQ
Common questions
The dataset's leading assignee holds 1,605 of the 5,487 records in scope, well ahead of the fifth-place filer at 262 and the tenth-place filer at 117. The field is dominated by mobile-communications and chipset firms rather than traditional traffic-infrastructure vendors, and the top five assignees together account for 51.6% of all records. That concentration means most of the broad wireless-communications claim space around roadside units is already occupied by a handful of filers.
Filing rose from 682 records in 2021 to 791 in 2024, a 16% increase, after an earlier peak of 869 records in 2022. The 2025 and 2026 figures look lower, but publication lags filing by roughly 18 months, so those years are still incomplete rather than genuinely down. Based on the last fully reported year, 2024, the trend was still upward, not slowing.
Most records classify under H04W (wireless communication networks), covering 64.0% of the 5,487 records, and H04L (digital information transmission), covering 27.6%. Traffic-control systems (G08G) and radar/positioning (G01S) — the classes closest to the physical infrastructure-sensing use case — cover smaller shares, 13.8% and 12.9% respectively. Because records can carry multiple IPC codes, these shares overlap and add up to more than 100%.
Comparing the class shares, wireless-protocol and general-transmission art is dense while classes tied to physical deployment — sensor calibration, edge-computing-node handover, backhaul fallback under line-of-sight loss, antenna placement and power-supply resilience — carry noticeably less filing density. That gap suggests infrastructure-specific hardware and deployment claims are less contested than the underlying communications protocols, though a full clearance search should confirm freedom to operate before drafting.
Ownership is concentrated: the top five assignees hold 51.6% of the 5,487 records in scope and the top ten hold 64.6%. Only ten co-assignee pairs appear across the dataset, with the strongest pair sharing 71 records, indicating that collaboration is limited and mostly occurs within chipset-and-inventor clusters rather than across the industry broadly.
