Patent Landscape · Temperature & Thermal SensorsTemperature and thermal sensor patents: who holds the claims and where the field is still open
- 6.1% concentration at the top. The five leading assignees hold just 2,586 of 42,188 records in scope — a genuinely long tail, not a two-player race.
- Filing has cooled from its 2017 peak. 1,168 records published that year against 52 so far in the most recent (partial) year, with a measured -35% drop from 2021 to 2024.
- Diagnosis and material-analysis classes dominate. A61B and G01N together anchor the technology mix, ahead of the core G01K temperature-measurement subclass itself.

Leading Jurisdiction
Filing growth compares 2021 (1,019 records) with 2024 (662) — 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 42,188 records in scope (CR5), not by the ranked leaders only.

Overview
What the temperature and thermal sensor patent record shows
Temperature and thermal sensing sits at the intersection of medical diagnostics, industrial control and consumer electronics, and the patent record reflects that spread. Across 42,188 records published between 2015 and the 2026 cut-off, claims range from body-worn analyte sensors that compensate for temperature drift to heat-flux measurement in industrial control loops. No single assignee dominates: the leading filer holds 647 records, and even the ranked leaders together account for a modest share of the total field.
The technology composition points to a field defined more by application context than by a single sensing principle. Diagnosis and surgery (A61B) and material analysis and testing (G01N) each carry a larger share of records than the core temperature-measurement subclass (G01K) itself, which signals that most filing activity treats temperature sensing as a supporting element inside a larger system claim rather than as a standalone invention.

The Data
Filing trends and technology composition
Publication counts by year and IPC subclass show where claim density sits today and how the field has moved since its 2017 peak.
Filing trend: a 2017 peak followed by a measured pullback
Filings peaked at 1,168 records in 2017. From 2021 (1,019) to 2024 (662) — the most recent year that can be treated as complete — the total fell 35%. Publication lags filing by roughly 18 months, so 2025 and 2026 figures are still filling in and should not be read as a continuing decline.
Technology composition: application context outweighs the core subclass
A61B (diagnosis and surgery) leads at 8.1% of the 42,188 records in scope, ahead of G01N (material analysis, 5.6%) and the core G01K temperature-measurement subclass itself (5.3%). Because a record can carry multiple IPC classes, these shares add up to more than 100% — they describe overlap, not a single ranked total.
Shares are the percentage of the 42,188 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

What the numbers mean for a filing decision
Three patterns matter more than the headline count: how concentrated ownership actually is, where the technology claims cluster, and which receiving offices carry the weight of filing activity.
Concentration
6.1%
top 5 share of 42,188 records
Ownership is genuinely dispersed
The top five assignees combine for 2,586 records, just 6.1% of the field, and the top ten add up to only 9.9%. That is a long tail of single- and few-filing entrants rather than a market gated by a handful of blocking portfolios.
Top 10 = 9.9% of 42,188 records
Technology mix
8.1%
A61B share of records
Diagnostic and surgical context leads the claim mix
A61B outranks the core G01K temperature-measurement subclass, meaning most temperature-sensing claims are filed as part of a larger diagnostic or surgical system rather than as a discrete sensor invention.
G01K core subclass sits at 5.3%
Filing momentum

2021 to 2024 change
Volume has eased from its 2017 peak
Filings fell from 1,019 in 2021 to 662 in 2024, a 35% decline over that span. The 2017 peak of 1,168 has not been approached since, though the most recent two years are still filling in under publication lag.

US-office records
Filing activity is US-centred with a broad international spread
The United States receiving office carries the largest single share of records, with the EPO, WIPO/PCT, Canada, Australia and the UK all showing meaningful but smaller volumes.

What's Next
Where to take this analysis
The dataset points to next steps for teams deciding whether to file, license or design around existing claims.
Map claim scope against the top-ranked portfolios
With concentration this low, freedom-to-operate work should focus on specific claim language in the leading few hundred records rather than assuming one or two companies control the field.
Explore assignee portfolios in EurekaTrack the under-claimed branches before they fill in
Thermal feedback in non-electric control systems and radiation-based temperature measurement show thinner density than core diagnostic claims, which narrows the window for a defensible first-mover filing.
Run a white space search in EurekaWatch the 2025-2026 filings as they publish
Because publication lags filing by roughly 18 months, the apparent slowdown in the newest years should be revisited once those cohorts finish publishing.

FAQ
Common questions about temperature and thermal sensor patents
The leading assignee in this dataset holds 647 of the 42,188 records in scope, with the fifth-ranked filer at 409 and the tenth at 291. That gradual taper, rather than a sharp cliff after the leader, means no single company controls the field outright. The top five assignees combined account for only 6.1% of all records, and the top ten reach 9.9%, so most of the landscape is held by a long tail of smaller filers.
Filings peaked in 2017 at 1,168 records and have eased since; the most recent complete comparison shows a 35% decline from 1,019 records in 2021 to 662 in 2024. Figures for 2025 and 2026 are still low, but that reflects publication lag of roughly 18 months rather than a genuine collapse in filing activity. Treat any conclusion about the very latest years with caution until those cohorts finish publishing.
The core classification is G01K (temperature measurement), which covers 5.3% of the 42,188 records in scope, but it is not the largest class touching this field. A61B (diagnosis and surgery) leads at 8.1%, and G01N (material analysis and testing) follows at 5.6%, reflecting how often temperature sensing is claimed as a supporting element of a medical or analytical system rather than as a standalone invention. Because records can carry multiple IPC codes, these percentages overlap rather than sum to a total.
The United States receiving office accounts for the largest share of records at 11,303, followed by the European Patent Office at 3,832 and WIPO's PCT route at 2,234. Canada, Australia and the United Kingdom each show smaller but meaningful volumes. This distribution suggests the US is the primary market for both defensive and enforcement filing strategy in this field, with Europe and PCT filings serving as the main secondary tier.
US12514471B2, assigned to Dexcom, describes systems and methods for compensating an in vivo analyte sensor reading using a temperature signal from a separate ex vivo temperature sensor, generating a temperature-compensated sensitivity value. It is narrowly directed at analyte-sensing accuracy correction rather than temperature measurement as a general-purpose function. Anyone working on wearable or implantable analyte sensors that use an external temperature reference for drift correction should review its claim scope directly rather than relying on the abstract alone.
