Thermal Imaging Camera Patents: Who Leads, Where Gaps Remain 2026
Thermal Imaging Camera Signal Processing Patents
52.7% concentration. The top five assignees alone account for 205 of 389 records in scope — a field where claim space near the core techniques is already crowded. Publications rose to a peak of 54 in 2018, then declined; the 2021-to-2024 span shows a -73% drop from 37 to 10 published records, the last full-year comparison the data supports. Years after 2024 are still accumulating publications and should not be read as a continued decline.

Common questions on thermal imaging signal processing patents
Who holds the most patents in thermal imaging camera signal processing?
One assignee leads the ranked field with 95 of the 389 records in scope, well ahead of the rest. The top five assignees combined hold 205 records, or 52.7% of all records, and the top ten hold 247 records, 63.5% of the total. Beyond the top ten, filing counts drop quickly into a long tail of companies and research bodies with just a handful of records each.
Is patent filing activity in this space growing or shrinking?
Published filings peaked at 54 in 2018 and had fallen to 10 by 2024, a -73% change from the 37 published in 2021. That decline is measured only through 2024 because publication lags filing by roughly 18 months, so 2025 and 2026 figures are still incomplete and should not yet be read as confirming a continued drop.
What patent classes cover thermal imaging signal processing techniques?
The largest share of records, 59.9% of the 389 in scope, falls under H04N (pictorial communication), followed by G01J (radiation and light measurement) at 36.8% and G06T (image data processing) at 31.1%. Smaller but active classes include G06V and G06K for recognition tasks, A61B for diagnostic overlap, G01K for temperature measurement, and G06F for general digital processing at 3.1%. Because a single record can carry several classes, these shares sum to more than 100%.
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 Thermal Imaging Camera Signal Processing 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.
