GNSS Jamming & Spoofing Detection Patents: Top Companies & Trends 2026
- 55.1% concentration. The top five assignees combined hold 1,651 of the 2,995 records in scope, so most of the claim space near existing filings is already occupied by a small group.
- +28% filing growth, 2021 to 2024. Filings rose from 212 to 271 over that span, the last three-year window unaffected by publication lag, showing sustained rather than cooling interest.
- Wireless-networking classes dominate over dedicated anti-jam codes. H04W and H04L cover 60.6% and 50.2% of records respectively, while H04K (secret & jamming communication), the classification built for this exact problem, appears on only 2.1%.
Filing growth compares 2021 (212 records) with 2024 (271) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 2,995 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This dataset tracks 2,995 published patent records filed between 2015 and mid-2026 that combine GNSS jamming detection, spoofing detection or interference mitigation claims with a specific mitigation or authentication mechanism — controlled reception pattern antennas, signal authentication, automatic gain control, power distortion monitoring, adaptive notch filtering or receiver autonomous integrity monitoring. The scope is deliberately narrow: it excludes generic GNSS positioning filings that do not touch interference or spoofing at all.
Because the search string requires both a detection/mitigation concept and a named technical mechanism, the corpus skews toward receiver-side and network-side signal processing rather than pure antenna hardware. Publication lags filing by roughly 18 months, so figures for 2025 and 2026 will keep rising as more applications publish; treat the most recent two years as a floor, not a ceiling.

Filing trend and technology composition
Filing volume and IPC composition together show where claim density sits today and where it is still forming.
Filings climbed through a 2022 peak and stayed elevated
Annual filings rose from 89 in 2017 to a peak of 288 in 2022, then settled to a still-elevated range; the 2021-to-2024 window shows +28% growth (212 to 271), the last period unaffected by publication lag. Readings for 2025 and 2026 are undercounts because recent applications have not all published yet.
Wireless-network classes carry the claim volume
H04W (wireless communication networks) touches 60.6% of the 2,995 records and H04L (digital transmission) touches 50.2%, reflecting that most filings frame jamming and spoofing as a network-layer signal-processing problem. G01S (radar, sonar & positioning), the classification closest to raw GNSS receiver design, sits at 12.3%, and H04K (secret & jamming communication) at just 2.1% — the narrowest slice despite naming the exact threat this dataset searches for.
Shares are the percentage of the 2,995 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

US12066551B2 — Multi-constellation, multi-frequency GNSS system for interference mitigation
A wideband interference mitigation module sits on the output of a primary downconverter to process the digital intermediate-frequency signal. A selective filtering module tied to a secondary downconverter uses a digital harmonic-resistant translator, combining an anti-aliasing low-pass filter sized to the target receive bandwidth with a narrow-band rejection filter that adapts to reduce electromagnetic interference in the digital baseband signal.Filed by Deere & Company, published 2024-08-20.

Three patterns matter more than any single ranking: where volume concentrates, how fast the field is still moving, and which classes are thin.
A small group holds most of the near-term claim space
With the leader alone at 852 records and the top five combined at 1,651 of 2,995, new entrants filing close to existing claim language in H04W and H04L are filing into dense prior art. The tenth-ranked assignee holds only 41 records, showing a sharp drop-off after the leaders rather than a gradual taper.
Sustained growth, not a plateau
The three-year window from 212 filings in 2021 to 271 in 2024 is the most recent period the data can support without publication-lag distortion, and it shows continued expansion rather than the cooling that a naive read of the 2025-2026 numbers might suggest.
The jamming-specific IPC class is the thinnest one tracked
H04K, the classification built specifically for secret and jamming communication, covers only 64 of 2,995 records versus 1,814 under the general wireless-networking class H04W. Most applicants are claiming interference mitigation as a feature of a broader communications system rather than as a dedicated anti-jam invention.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to gnss interference jamming and spoofing detection, with the prior art for and against each one.
Who is filing, and where activity is cooling
Leadership by volume does not match leadership by recent momentum: several of the largest historical filers show sharp year-over-year declines, which is a different signal from being absent from the field.
One assignee holds close to a third of the corpus alone
The leading assignee's 852 records against a 2,995-record total sets the density any competitor must file around in the core wireless-network classes.
Recent-year filing has cooled sharply among some top assignees
Two of the largest historical filers show 15 records in the latest year against year-over-year declines of -76% and -90%, and several other established names show zero filings in the latest year. Given publication lag, this partly reflects filings still in the pipeline rather than withdrawal from the field.
Co-filing is limited and concentrated in a few relationships
Only 10 co-assignee pairs appear in the dataset, with the strongest pairing appearing 11 times; most assignees in this field file independently rather than through joint ventures or shared ownership.

| Qualcomm Inc. | 15 | -76% |
| DIGITAL GLOBAL SYSTEMS INC | 15 | -90% |
| LG Electronics Inc. | 1 | 0% |

Where to take this analysis
The figures above describe the field as a whole; the next step is usually narrowing to a specific claim, competitor or gap.
Check freedom-to-operate against the top holders
With 55.1% of records held by five assignees, a claim chart against their core filings is a faster first step than a full landscape search.
Run a claim comparison in EurekaTrack momentum shifts as they publish
Several large filers show steep year-over-year declines that may reverse once pending applications publish; monitoring alerts catch that shift early.
Set up monitoring in EurekaDraft around the thin classes
H04K and G01S remain lightly claimed relative to H04W and H04L; drafting a first claim there starts from open ground rather than dense prior art.

One assignee leads with 852 of the 2,995 records in scope, and the top five combined account for 55.1% of all records. The drop-off is steep rather than gradual: fifth place holds 91 records and tenth place holds 41, so the field has a small concentrated leadership group followed by a long tail of single- or few-filing entrants. This pattern means freedom-to-operate work should prioritise the leading handful before broadening to the full ranked list.
Yes, based on the last complete three-year window: filings grew from 212 in 2021 to 271 in 2024, a 28% increase. Annual filings peaked at 288 in 2022 and have stayed elevated since. Figures for 2025 and 2026 appear lower only because publication typically lags filing by about 18 months, not because filing activity has actually declined.
Most records sit in wireless-network and digital-transmission classes rather than dedicated anti-jam classifications: H04W (wireless communication networks) covers 60.6% of the 2,995 records and H04L (digital information transmission) covers 50.2%. Radar and positioning-specific claims under G01S appear in 12.3% of records, and the classification built specifically for jamming and secret communication, H04K, appears in only 2.1%. This suggests most applicants treat interference mitigation as a feature within a broader communications system rather than a standalone invention.
US12066551B2, assigned to Deere & Company and published 2024-08-20, claims a multi-constellation, multi-frequency GNSS receiver architecture built around a wideband interference mitigation module fed by a primary downconverter, paired with a selective filtering module on a secondary downconverter that combines an anti-aliasing low-pass filter with an adaptive narrow-band rejection filter. It is a receiver-architecture claim rather than an algorithm-only claim, which means it primarily blocks specific hardware/firmware filter-chain configurations rather than detection methods in general. Anyone designing a similar dual-downconverter filtering chain should check this claim's specific limitations before proceeding.
The clearest gaps by IPC composition are H04K (secret and jamming communication, 2.1% of records) and G01S (radar, sonar and positioning, 12.3%), both far below the 60.6% share held by general wireless-networking claims under H04W. Combining a thin class with a named but lightly claimed mechanism, such as power distortion monitoring or adaptive notch filtering tied to multi-constellation receivers, is a reasonable starting point for a first claim. Co-filing is also rare in this field, with only 10 identified co-assignee pairs, suggesting joint-venture filing strategies are underused relative to solo filing.
