V2X Security Patents: Who Leads, Where the Gaps Are 2026
V2X Security and Certificate Management Patents: Who Holds the Pseudonym Certificate Claims
Top 5 filers hold 66.1% of all 280 records in scope — a small group has locked up most of the pseudonym-certificate and misbehavior-detection claim space. Filings climbed from 11 in 2017 to a peak of 60 in 2023, then dropped to 19 by 2024 — a 65% decline from the 2021 level of 55. Because publication lags filing by roughly 18 months, 2025 and 2026 figures are still incomplete and should not be read as confirmation that the field is winding down.

Common questions about this landscape
Who holds the most patents in V2X security and certificate management?
Filing is heavily concentrated: the top five assignees together hold 185 of the 280 records in scope, or 66.1% of the field, and the leading single assignee alone accounts for 93 records. That gap between the leader and even the fifth-place filer (16 records) means most freedom-to-operate risk in pseudonym-certificate and revocation claims sits with a small handful of companies rather than being spread evenly across the field. Anyone assessing risk should start with this small group before looking at the long tail of single-filing entrants.
Is patent filing in V2X security growing or slowing down?
Filings rose from 11 in 2017 to a peak of 60 in 2023, then fell to 19 by 2024 — a 65% decline over that three-year window. However, publication typically lags filing by about 18 months, so the 2025 and 2026 figures in any dataset are still incomplete and should not be read as proof the field is cooling. The safest complete comparison right now is 2021 to 2024, and that comparison does show a real pullback from the 2023 peak.
What technology areas do these patents cover most?
Over half of the 280 records fall under H04W (wireless communication networks, 54.3%) and H04L (digital information transmission, 52.5%), meaning most claims describe how certificates and misbehavior reports move through the V2X messaging stack. Traffic control (G08G) and general data processing (G06F) form a secondary tier around 15% each. Cryptographic-primitive classifications like G09C appear in only 2.1% of records, suggesting the field claims protocol behaviour far more often than the underlying cipher mechanics.
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.
Method: Filing trend and technology composition. Derived from a Patsnap search on V2X Security and Certificate Management covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
