Offshore Substation & Export Patents: Top Companies, Trends 2026
Offshore Substation and Export Systems Patents: Who Leads and Where the Gaps Sit
Concentrated at the top. the leading assignee holds 10 records and the top 5 together account for 40.6% of all 96 records in scope. Filings rose from 4 in 2017 to a peak of 18 in 2022, then fell to 2 by 2024 — a 71% decline over that three-year window. 2025 and 2026 figures will continue to fill in as later-filed applications publish, so treat the tail as incomplete rather than as a genuine falloff.

Common questions on offshore substation and export system patents
Who holds the most patents in offshore substation and export cable systems?
Within this dataset the leading assignee holds 10 of the 96 records in scope, with the top 5 assignees together accounting for 39 records, or 40.6% of the total. The ranking runs to 34 companies, so beyond the top 5 there is a long tail of firms with only a handful of filings each. Company names appear in the ranking table itself; treat position as a measure of filing history rather than current commercial strength, since several top filers show no activity in the most recent tracked year.
Is patent filing in offshore substation technology increasing or slowing down?
Filings peaked at 18 records in 2022 and declined to 2 by 2024, a 71% drop over that three-year span. However, publication typically lags actual filing by around 18 months, so 2025 and 2026 figures in any dataset are structurally incomplete and should not be read as proof of a continued slowdown. The safest statement is that activity was well past its peak by 2024; the trajectory since then is still filling in.
What technology areas dominate offshore substation patent claims?
F03D (wind motors and turbines) appears on 42.7% of the 96 records and H02J (power supply and grid systems) on 32.3%, making these the two largest technology classes. B63B, covering ships and marine vessels, appears on 21.9% of records, reflecting how much offshore substation art is framed around vessel-mounted or floating platform hardware. Narrower classes such as power conversion, cable installation and connectors each sit between roughly 7% and 12%, indicating more specific but less contested claim territory.
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 Offshore Substation and Export Systems 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.
