Transmission Tower Patents: Who Leads, Where the Gaps Are 2026
Transmission Tower Design and Foundation Patents
Concentrated but not locked up. the top 5 assignees hold 36.7% of all 128 records in scope, and the top 10 hold 56.3% — leaving a wide field of single- and double-filing entrants. Filings rose to a peak of 13 records in 2020, then eased; the documented move from 3 records in 2021 to 2 in 2024 is a -33% shift over that span. 2025 and 2026 figures are still incomplete because publication typically lags filing by around 18 months, so the recent-year dip should not be read as a slowdown yet.

Common questions on transmission tower patents
Who holds the most patents in transmission tower design and foundations?
In this dataset of 128 records, one assignee leads with 14 records, followed by a gradual drop-off to 6 records at fifth place and 4 at tenth. The top 5 assignees together hold 36.7% of all records and the top 10 hold 56.3%, meaning leadership is real but far from exclusive. A further 62 companies appear in the ranking, most holding only a handful of filings each, which points to an active field rather than one locked up by a single player.
Is transmission tower patent filing activity growing or slowing down?
Filings peaked at 13 records in 2020 and the documented change from 2021 (3 records) to 2024 (2 records) works out to -33% over that span. However, publication typically lags actual filing by roughly 18 months, so the lower counts showing for 2025 and 2026 in this dataset are incomplete rather than evidence of an ongoing decline. The 2024 figure is the most recent one that can be treated as a complete year.
Why do wind turbine patents show up in a transmission tower search?
Because a large share of tower-foundation and erection-method innovation in this dataset is being filed through wind-turbine support structures rather than pure grid-transmission towers. F03D (wind motors) appears on 40.6% of the 128 records, often alongside E04H (specialised structures), reflecting that lattice and tubular tower engineering for turbines and for power lines increasingly draws on the same structural and foundation techniques.
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 Transmission Tower Design and Foundations 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.
