Time-Temperature Indicator Patents: Who Leads, Where the Gaps Are 2026
Time-Temperature Indicator Label Patents: Concentration, Trends and White Space
One company holds 39 of 80 records in scope, and the top 5 assignees combined account for 81.3% of all filings — this field is unusually concentrated for a packaging niche. Filings rose from zero in 2017 to a peak of 6 in 2021, then fell to 0 by 2024 — a -100% change over that span. Because publication lag affects the most recent years most, this reads as a mature, already-claimed core rather than a technology in active retreat.

Common questions about TTI label patents
Who owns the most time-temperature indicator patents?
One assignee holds 39 of the 80 records in this dataset, roughly half of all filings in scope. The top five assignees combined account for 81.3% of all records, and the top ten reach 100% coverage of the dataset. This means the field’s foundational detection mechanisms are concentrated in a small number of hands, and any freedom-to-operate review should start there.
Is the time-temperature indicator patent field still growing?
Filing activity peaked at 6 records in 2021 and fell to 0 by 2024, a -100% change over that span. Because publication typically lags filing by around 18 months, the 2025 and 2026 figures in this dataset are still incomplete and should not be read as an active decline. Taken together, the pattern looks like a filing wave that crested in 2021 and has since settled rather than a technology that is actively growing.
What technology areas dominate TTI label patents?
Two IPC subclasses dominate: G01K (temperature measurement), present on 71.3% of the 80 records, and G01N (material analysis and testing), present on 66.3%. Because a single record can carry multiple IPC classes, these shares overlap rather than add to 100%. Narrower classes like C12N (microorganisms and genetic engineering) and C09D (coatings, paints and inks) sit at single-digit shares, marking areas with comparatively less claim density.
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 Time-Temperature Indicator Labels 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.
