GNSS Timing Patents: Who Leads, Where the Gaps Are 2026
GNSS Timing and Frequency Distribution Patents: Who Holds the Holdover Oscillator Ground
Concentration at the top. the leading five assignees combined hold 42.9% of all 497 records in scope, and the leading ten hold 55.1% — a narrow group of filers controls most of the claim space. Filing rose from 19 records in 2017 to a peak of 30 in 2023. The 2021-to-2024 window shows a -19% change (16 to 13 records), and 2025-2026 figures will rise as publications still under the roughly 18-month filing-to-publication lag come through — they should not be read as a real decline yet.

Common questions on GNSS timing patents
Who holds the most patents in GNSS timing and frequency distribution?
The leading assignee in this dataset holds 114 of the 497 records in scope, well ahead of the fifth-ranked filer at 20 and the tenth at 10. The leading five assignees together hold 42.9% of all records, and the leading ten hold 55.1%, so filing is concentrated in a narrow group at the top with a long tail of smaller filers below. Anyone assessing freedom to operate should check that top group’s portfolios first before widening the search.
Is GNSS timing patent filing growing or slowing down?
Filing rose from 19 records in 2017 to a peak of 30 in 2023, then the 2021-to-2024 comparison shows a -19% change. Because publication lags filing by roughly 18 months, the 2025 and 2026 figures in any chart are still incomplete and will rise as more filings publish, so this should be read as an easing from a 2023 peak rather than a confirmed decline. Treat any conclusion drawn from the last one to two years with caution.
What technology areas cover the most GNSS timing patents?
G01S, covering radar, sonar and positioning, appears in 41.0% of the 497 records in scope, and H04W, wireless communication networks, appears in 33.2%. Transmission-related classes H04B and H04L follow at 30.8% and 26.2%. Dedicated clock and timepiece classes G04G and G04R are much smaller at 9.9% and 3.8%, showing that most timing inventions are claimed as part of a positioning or communications system rather than as standalone oscillator hardware.
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 GNSS Timing and Frequency Distribution 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.
