Humidity Sensor Patents: Who Leads, Where the Gaps Are 2026
Humidity and Moisture Measurement Patents: Filing Trends and Leading Assignees
No single company dominates. the top 5 assignees together hold just 15.8% of all 9,357 records in scope, and the top 10 only 21.6% — this field has a long tail rather than a gatekeeper. Annual filings rose from 473 in 2017 to a peak of 687 in 2022, then eased to 530 by 2024 — a -12% move from the 2021 level of 600. The 2025-2026 figures are still filling in and should not be read as a decline.

Common questions about this landscape
Who holds the most humidity and moisture measurement patents?
The leading assignee holds 592 records in this dataset, a steep drop from fifth place at 127 and tenth place at 85. Even so, the top 5 assignees combined account for only 15.8% of the 9,357 records in scope, and the top 10 for 21.6%, so no single company controls the field. The ranked leaders mix consumer electronics, industrial controls, connected-health device makers and telecom-standards holders, reflecting how broadly moisture sensing has been embedded into other product categories.
Is the humidity sensor patent field still growing?
Filing volume rose from 473 records in 2017 to a peak of 687 in 2022, then eased to 530 by 2024 — a -12% change from 2021’s 600. That reads as a moderation off a peak rather than a collapse. Figures for 2025 and 2026 are still incomplete because publication lags filing by roughly 18 months, so any apparent recent drop should not be treated as a real slowdown until later data fills in.
What technology areas dominate humidity sensor patent claims?
G01N, material analysis and testing, is the single largest IPC class, touching 20.1% of the 9,357 records in scope. H04W wireless networks (9.1%) and G06F digital data processing (8.4%) follow, well ahead of air conditioning, diagnostic and control-systems classes. Because a single record can carry multiple IPC codes, these shares add up to more than 100%, and they show that moisture-sensing claims increasingly overlap with connectivity and data-processing claims rather than sitting in a standalone sensor category.
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 Humidity and Moisture Measurement 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.
