Run your analysis now →Filing growth compares 2021 (22 records) with 2024 (12) — 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 125 records in scope (CR5), not by the ranked leaders only.
Cooperative perception covers systems where vehicles, roadside units or edge servers exchange raw or processed sensor data so that each node perceives beyond its own line of sight. The search scope here pairs core sharing and fusion concepts — cooperative perception, sensor data sharing, point cloud fusion — with the mechanics that make sharing usable in practice: temporal alignment, coordinate transformation, occlusion handling, data redundancy, transmission latency and object matching. That combination is deliberate: a patent that only claims data sharing without addressing latency or alignment rarely survives contact with a real multi-vehicle deployment.
The corpus spans 125 published records filed between 2017 and 2026, with publication naturally lagging filing by roughly 18 months, so the final year or two will fill in as more applications publish. Records are drawn across major receiving offices, with the United States, the EPO and India carrying the largest volumes, giving a reasonably global read on where this technology is being protected rather than a single-jurisdiction snapshot.
Two views of the same 125 records: how filing volume has moved year over year, and which IPC subclasses carry the claim weight.
Filings rose from 7 in 2017 to a peak of 22 in 2021, then declined to 12 by 2024 — a 45% drop over that three-year span. 2025 and 2026 figures are still incomplete due to publication lag and should not be read as a continued decline.
H04W (wireless communication networks) appears in 43.2% of records, ahead of G06T (image data processing, 23.2%) and G08G (traffic control systems, 20.0%). Because a single record can carry several IPC classes, these shares sum to more than 100% and should be read as class prevalence, not a partition of the corpus.
Shares are the percentage of the 125 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Try EurekaDescribes a cooperative perception system where a first subsystem with a sensor, communication device and processor detects point cloud data, preprocesses it, encodes features, applies adaptive feature filtering to select a subset of features, and then fuses that subset with data from other subsystems through cooperative feature aggregation.Filed by The Regents of the University of California; published 2025-11-06.

Citation counts favour older filings simply because they have had more time to accumulate citations within the searched corpus — treat this as a signal of influence on the field to date, not a ranking of current technical importance.
Patent titles are shown in the language they were filed in, not translated, so that each record stays verifiable against the original filing — a translated title will not match in Eureka or in any national register. Each row carries its publication number; clicking a row searches Eureka by that number.

Browse MCP servers →Three read-throughs of the concentration, trend and classification data that matter for anyone deciding where to file next or who to watch.
One assignee alone accounts for 21 of the 125 records in scope, and the top five combined hold 40.8% of everything. That is a narrower concentration than a long, even tail would produce — new entrants are more likely to find room by working around a small number of dominant filers than by competing against a diffuse field.
Filing rose steadily to a 2021 peak of 22 records before falling to 12 by 2024, a 45% decline over three years. That decline predates the publication-lag window, so it reflects an actual pullback in filing activity rather than incomplete data — worth checking whether it tracks a maturing core architecture or a shift toward fewer, larger filers.
Wireless communication networks (H04W) appear in 43.2% of records, more than double the next class (G06T image processing, 23.2%), while image/video recognition (G06V) sits at just 8.0%. The heaviest claim traffic sits on how data moves and gets synchronised, not on how it is recognised or classified once received.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to cooperative perception and data fusion, with the prior art for and against each one.
A small group of automotive, telecom and chipset firms hold the largest single blocks, but the ranked list runs to 60 companies with a long tail of single- or few-filing entrants.
The leading assignee's 21 records is well ahead of fifth place at 5 and tenth place at 4 — the drop-off from first to fifth is steep, then the ranking flattens into a long tail. That shape suggests one or two players built an early, broad portfolio while most others are still staking out narrower positions.
Only three co-assignee pairings appear in the data, and the strongest links sit between a major automaker and its brand subsidiary, and between two divisions of a common automotive supplier. Joint filing is not yet a common strategy in this field; most portfolios here are built by a single entity.
The United States receives the largest share of filings, with the EPO, India and China each carrying a meaningful secondary volume and a further slice routed through the WIPO PCT track. A portfolio strategy built only around US and European offices would still miss the China and India volume visible here.

The dataset points to a field with a settled communication layer and thinner claim coverage on the perception and recognition side.
With one assignee holding 21 of 125 records, any new filing in the core sharing-and-fusion space should be checked against that portfolio's claim scope before drafting, not after.
Explore assignee portfolios in EurekaA 45% drop from peak filing is a real signal, but 2025-2026 data is still incomplete under normal publication lag; revisit this trend once those years settle.
Set up a filing-trend alert in EurekaOcclusion-aware filtering and cross-sensor temporal re-alignment show thinner density than the wireless-communication core — useful territory to check before writing claims that default to the crowded H04W framing.
Run a white-space search in EurekaRecords were selected for combining a sharing or fusion concept — cooperative perception, sensor data sharing or point cloud fusion — with a mechanism that makes that sharing workable in practice, such as temporal alignment, coordinate transformation, occlusion handling, data redundancy, transmission latency management or object matching. This dual requirement filters out patents that merely mention sensor sharing in passing without addressing how it is actually implemented. The scope covers 125 published records filed between 2017 and 2026.
The ranking covers 60 companies, with the single leading assignee holding 21 of the 125 records in scope and the top five together accounting for 40.8% of all records. Beyond the top ten, which together hold 56.8%, the ranking flattens into a long tail of companies with only a handful of filings each. That shape means a competitive read should focus on the handful of large portfolio holders rather than treating the field as evenly distributed.
Filing volume rose from 7 records in 2017 to a peak of 22 in 2021, then fell to 12 by 2024, a 45% decline over that three-year span. That is the most recent year the dataset treats as complete; 2025 and 2026 counts are still filling in because publication typically lags filing by around 18 months, so those final years understate true activity and should not be read as evidence of an accelerating decline.
Wireless communication networks (H04W) appear in 43.2% of the 125 records, making it the most heavily claimed subclass, followed by image data processing (G06T) at 23.2% and traffic control systems (G08G) at 20.0%. Image and video recognition (G06V) appears in only 8.0% of records, suggesting the recognition side of cooperative perception carries comparatively lighter claim density than the communication and traffic-management side. Because records can carry multiple IPC classes, these percentages do not sum to 100%.
The clearest openings sit in sub-areas adjacent to the dense communication core rather than inside it: occlusion-aware feature filtering, cross-sensor temporal re-alignment, redundancy-aware bandwidth allocation, object re-identification across viewpoints and edge-server fusion arbitration all show thinner filing density than the wireless-communication and traffic-control classes that dominate the corpus. Co-filing is also rare, with only three identified co-assignee pairs, suggesting joint-development claim strategies remain largely untried. A new filer should map claim language in these adjacent branches before defaulting to the crowded H04W framing.
