Wireless Industrial Sensor Networks Patents: Top Filers & Trends 2026
Wireless Industrial Sensor Network Patents: Who Files, What They Claim, and Where the Field Is Still Open
46.5% concentration. The top 5 assignees hold 519 of 1,115 records in scope — filings cluster hard at the top, with a long tail behind them. Filings rose from 37 in 2017 to a peak of 203 in 2021, then declined 82% to 36 by 2024 — the last year in the window that can be treated as complete given typical 18-month publication lag. Read 2025-2026 as still filling in, not as a continued fall.

Common questions about this landscape
Who holds the most patents in wireless industrial sensor networks?
The assignee ranking in this dataset is led by a single company with 242 of the 1,115 records in scope, well ahead of the fifth-ranked assignee at 43. The top 5 assignees combined hold 46.5% of all records, and the top 10 hold 60.5%, so filing activity is concentrated among a small group rather than spread evenly across the 100 ranked companies. Anyone assessing competitive position in this space should start with that top group before looking at the long tail.
Is patent filing in wireless industrial sensor networks growing or slowing?
Filing volume rose sharply to a peak of 203 records in 2021, then fell 82% to 36 records by 2024, the most recent year that can be treated as complete given typical publication delay. Records from 2025 and 2026 will continue to be added as they publish, so the apparent recent drop should not yet be read as a permanent slowdown. The safest comparison point remains the 2021-to-2024 change, since it avoids the partial final years.
What does US9237505B2 actually cover?
US9237505B2, held by GLOBALFOUNDRIES U.S. INC. and granted in January 2016, claims a method for routing data packets through a wireless sensor network mesh in which intermediate nodes operate on a sleep-active schedule, alternating between sleep and active modes while still forwarding traffic between a source and destination node. It sits within a broader cluster of patents conditioning mesh routing decisions on node power states, so anyone designing sleep-scheduled mesh routing should review it directly. It does not cover static, always-on mesh routing implementations that lack a sleep-active duty cycle.
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.
