Multipath Mitigation GNSS Patents: Who Leads, Where Gaps Are 2026
Multipath Mitigation in GNSS Positioning: Patents, Leaders and Filing Trends
49.0% of all 394 records sit with just five assignees, so the core correlator and antenna-design claim space is already dense near the top of the field. Annual filings rose from 17 in 2017 to a peak of 26 in 2021, then fell to 8 by 2024 — a 69% decline over that three-year span. Readers should treat 2025 and 2026 counts as provisional given the typical 18-month gap between filing and publication.

Common questions about this landscape
Who holds the most patents in GNSS multipath mitigation?
One assignee leads the ranked field with 63 patent families, well ahead of the fifth-ranked company at 20. The top five assignees together hold 49.0% of all 394 records in scope, and the top ten hold 64.0%. Below that, the ranking spreads across 100 companies total, with most holding only a handful of filings each, so the field has a concentrated top and a long tail beneath it.
Is patent filing activity in this field growing or shrinking?
Filings rose from 17 in 2017 to a peak of 26 in 2021, then fell to 8 by 2024, a 69% decline over that three-year span. That said, publication typically lags filing by roughly 18 months, so 2025 and 2026 counts in any dataset are understated and should not yet be read as a continued decline. Anyone using this trend for strategic timing should treat 2024 as the most recent reliable data point.
What patent classes cover GNSS multipath mitigation techniques?
The dominant class is G01S, covering radar, sonar and positioning systems, present in 83.8% of the 394 records in scope. H04B transmission techniques follow at 38.6%, with smaller footprints in H04W wireless networks (14.7%), G01C navigation instruments (8.4%), H01Q antennas (6.1%), G08G traffic control (4.8%) and H04J multiplexing (3.6%). Because a single record can carry several of these classes, the shares add up to well over 100% and should each be read against the full record count rather than against each other.
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 Multipath Mitigation in GNSS Positioning covering 2015–2026, data cut-off 2026-07-31.
