Traffic Collision Avoidance System Patents: Filing Trends and Who Holds the Ground
54.6% concentration. The top 5 assignees hold 534 of 978 records in scope — over half the field sits with a handful of avionics and defense majors. Filings rose from 22 records in 2017 to a peak of 31 in 2018, then declined through the early 2020s. The clearest complete-year comparison is 2021 (30 records) against 2024 (5 records), an 83% drop over three years. Treat 2025 and 2026 as incomplete rather than as confirmation the field has gone quiet.

Common questions on traffic collision avoidance patents
Who holds the most patents on traffic collision avoidance systems?
The dataset's leading assignee holds 248 of the 978 records in scope, well ahead of the fifth-ranked filer at 40 and the tenth at 18. The top 5 assignees combined account for 54.6% of all records, and the top 10 for 66.4%, so the field is concentrated at the top with a long tail of smaller filers behind it. That concentration pattern is typical of avionics safety systems, where a small number of established suppliers file continuation and improvement patents around a core architecture over many years.
Why have collision avoidance patent filings declined since 2021?
Filings fell from 30 records in 2021 to 5 in 2024, an 83% drop over that complete-year span, following a peak of 31 records in 2018. This could reflect a maturing core architecture where fewer new claims are needed, consolidation among the leading filers, or a shift in R&D toward adjacent areas like UAS traffic management. It is worth noting that 2025 and 2026 figures are still incomplete due to the roughly 18-month lag between filing and publication, so the most recent apparent decline should not be read as the final word.
What technology areas do most collision avoidance patents cover?
The two largest IPC classes are G08G (traffic control systems), appearing in 60.1% of the 978 records, and G01S (radar, sonar and positioning), appearing in 50.9%. Because a single patent can carry multiple classification codes, these two overlap substantially, indicating most filings combine surveillance sensing with traffic-control decision logic rather than treating them as separate inventions. Smaller but notable classes include G01C (navigation, 15.1%) and B64D (aircraft equipment, 12.4%), showing links to broader avionics and navigation claims.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
