Lightning Location Patents: Who Leads, Where the Gaps Are 2026
Lightning Location and Detection Network Patents: Leaders, Trends and Open Claim Space
Five assignees hold 59.7% of the field. 83 of the 139 records in scope sit with the top five filers, and the next five add another 26 records to bring the top ten to 78.4% — this is a concentrated technology, not a fragmented one. Filings climbed to a peak of 20 in 2018, held near double digits through the following years, then fell to 8 by 2021 and to 0 by 2024 — a complete drop-off over that three-year span. Treat 2025 and 2026 counts as incomplete rather than as evidence the field has stopped.

Common questions about lightning detection patents
Who are the leading patent holders in lightning location and detection networks?
The dataset’s assignee ranking covers 43 companies, and it is top-heavy: the leading assignee alone holds 25 of the 139 records in scope, while the top five combined account for 59.7% of the field. Below the top ten filers, activity spreads into a long tail of single- and few-filing entrants, including universities and wind-energy manufacturers applying the technology to new use cases. Anyone assessing this space should treat the top few filers as the ones whose portfolios matter most for freedom-to-operate purposes.
Why did lightning detection patent filings drop after 2018?
Filings peaked at 20 in 2018 and fell steadily afterward, reaching 8 by 2021 and 0 by 2024, a complete drop across that three-year span. Part of this reflects normal publication lag: patents typically publish about 18 months after filing, so 2025 and 2026 figures are still incomplete and should not be read as a confirmed end to activity. The decline nonetheless indicates that fewer new applications have entered the public record recently compared with the 2017-2019 period.
What technology areas does lightning location patenting actually cover?
Two IPC classes dominate: G01W (meteorology) appears in 48.2% of the 139 records and G01R (electric and magnetic measurement) in 46.8%, meaning most filings frame the problem as either weather-sensing or signal-measurement. G01S, covering radar and positioning methods, appears in 23.0% of records as a secondary framing. Smaller but real clusters exist around power-grid integration (H02J, 10.8%) and sports or venue safety alerting (A63B, 7.2%), both of which carry noticeably lower filing density than the core classes.
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 Lightning Location and Detection Networks 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.
