Infrared Gas Detection Patents: Who Leads, Where Gaps Are 2026
Infrared Gas Detection Patents: Mapping the Leaders and the Open Ground
22.2% concentration at the top. The five leading assignees combined hold 116 of 523 records in scope — a real lead, but not a lock on the field. Filings peaked in 2017 at 44 and cooled afterward, but the 2021-to-2024 window shows a genuine rebound — from 14 filings to 22, a 57% increase over three years. Treat 2025 and 2026 as undercounted rather than as a slowdown; publication lag alone accounts for the drop-off visible in the most recent bars.

Common questions about infrared gas detection patents
How concentrated is the infrared gas detection patent field?
It is moderately concentrated but not dominated by a single player. The five leading assignees combined hold 116 of the 523 records in scope, which works out to 22.2% of the field. The leader alone holds 34 records, with the fifth-ranked assignee at 18 and the tenth at 13, so the drop-off from the top is gradual rather than a cliff. A new entrant should expect to compete against an established but not monopolistic set of filers.
Is filing activity in infrared gas detection growing or slowing?
The reliable read is growth. Filings rose from 14 in 2021 to 22 in 2024, a 57% increase over that three-year span, and 2024 is the most recent year with a complete publication record. The 2017 peak of 44 filings was higher, but publication lags filing by roughly 18 months, so figures for 2025 and 2026 are undercounted and should not be read as a decline. Judged on complete years, the trend is upward, not falling.
What technology areas dominate infrared gas detection patent claims?
G01N, the material analysis and testing classification, covers 82.6% of the 523 records, confirming that most claims are still built around measurement accuracy problems like interference correction and calibration rather than a specific end-use product. G01J, radiation and light measurement, is the next largest at 17.4%. Smaller but meaningful shares sit in diagnostics (A61B), business/data processing (G06Q), animal husbandry (A01K), alarm systems (G08B) and flow measurement (G01F), showing the core sensing method spreading into several application areas.
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 Infrared Gas Detection 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.
