Floating Offshore Wind Platform Patents: Leaders & White Space 2026
Filing growth compares 2021 (32 records) with 2024 (26) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 165 records in scope (CR5), not by the ranked leaders only.
What this patent set covers
Semisubmersible floating-wind platforms sit at the intersection of marine hull engineering and wind turbine design, which is why the strongest technology signal in this dataset is B63B — ships and marine vessels — rather than a wind-specific class. The 165 records in scope span filings from 2015 through the current data cut-off, capturing the period in which floater geometry, mooring architecture and station-keeping control moved from demonstration projects toward pre-commercial arrays. Publication lags filing by roughly 18 months, so the last one to two years in any trend line understate real filing activity.
Reading this set alongside the receiving-office split is useful: filings concentrate in the United States, Europe and under the PCT route, which tracks where floating-wind demonstration and pilot-array activity has actually happened rather than where turbines are ultimately deployed.
Filing trends and technology composition
Two views of the same 165-record set: how filing volume has moved year over year, and how records distribute across the technology classes that define a floating platform design.
Filing trend, 2017-2026
Filings rose from 2 in 2017 to a peak of 35 in 2022, then eased to 26 by 2024 (a 19% decline from the 2021 level of 32). 2025 and 2026 figures are still incomplete due to publication lag and should not be read as a real slowdown yet.
IPC subclass composition
B63B (ships & marine vessels) appears on 76.4% of the 165 records and F03D (wind motors) on 59.4%, confirming that most filings claim hull or turbine-integration structure. E02D (foundations) at 13.3% and E02B (hydraulic/waterway engineering) at 11.5% are present but comparatively thin, and F16G, B63H, F03B and F17C each cover under 3% of records — these are secondary or componentry classes, not core battlegrounds.
Shares are the percentage of the 165 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Floating wind turbine systems and methods (US12631161B2)
A method of operating a downwind floating wind turbine that maintains a defined mean heel angle — the pitch of the tower's central axis relative to wind direction — while operating with a maximum rotor misalignment from the horizontal. The turbine's blades rotate about a rotor axis with a defined tilt angle, and the claims tie heel angle, rotor tilt and misalignment together as an operating envelope rather than a fixed structural geometry.Filed by Aikido Technologies, published 2026-05-19 — the only assignee in this set with a filing in the most recent year.

Three findings that change where a design or freedom-to-operate review should start.
A short leader list, not a fragmented field
With the leader alone at 37 records and the top five combined controlling 55.8% of all 165 records in scope, freedom-to-operate work in this space is really a small-set clearance exercise against a handful of applicants rather than a broad landscape scan.
2022 was the high point so far
Filings peaked at 35 in 2022 before easing to 26 by 2024, a 19% pull-back from the 2021 level of 32. Because publication lags filing by around 18 months, 2025-2026 counts are still incomplete and should not yet be read as a genuine cooling of interest.
Hull and vessel claims outweigh foundation claims
B63B and F03D together dominate the technology mix, meaning most protected ground concerns hull form, load transfer and turbine integration. Foundation-specific claims under E02D sit at just 13.3% of records, and hydraulic/waterway engineering under E02B at 11.5% — comparatively open ground for anchoring and seabed-interface innovation.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to floating offshore wind — semisubmersible floating-wind platforms patent landscape, with the prior art for and against each one.
Where to take this next
The dataset points to specific next steps depending on whether the goal is clearance, whitespace scouting, or monitoring a named competitor.
Run a freedom-to-operate check against the top five
Since the top five assignees hold 55.8% of all 165 records, a targeted clearance review against just this group covers most of the crowded claim space before any broader search is needed.
Explore assignee claims in EurekaScope a filing in an under-claimed branch
E02D foundation claims and E02B hydraulic/waterway claims sit well below the density of B63B and F03D, suggesting mooring, anchoring and seabed-interface work still has room for a defensible first claim.

Aikido Technologies is the only assignee with a filing in the latest year in this set; watching how its claims around heel angle and rotor misalignment develop is a useful early signal for where the field moves next.

One assignee leads the ranked field with 37 of the 165 records in scope, noticeably ahead of the rest. The top five assignees combined hold 55.8% of all records, and the top ten hold 81.8%, so the field is concentrated among a short list of applicants rather than spread evenly. Any competitive or freedom-to-operate review should start with that leader group before widening the search.
Filing activity peaked in 2022 at 35 records and had eased to 26 by 2024, a 19% decline from the 2021 level of 32. Because patent publication typically lags filing by around 18 months, the 2025 and 2026 figures in any dataset are still incomplete, so this should be read as normalisation after a 2022 peak rather than a confirmed downward trend. A clearer read on 2025-2026 activity will only be possible once those years finish publishing.
Most records claim hull and vessel structure under IPC class B63B, which touches 76.4% of the 165 records, followed by wind turbine integration under F03D at 59.4%. Foundation engineering (E02D) and hydraulic or waterway engineering (E02B) appear on 13.3% and 11.5% of records respectively, and componentry classes like cables, propulsion and pressure vessels each cover under 3%. Because a single record can carry several IPC classes, these shares add up to more than 100%, which is expected.
The United States receives the most filings in this set at 47, followed by the European Patent Office at 35 and the WIPO PCT route at 25. Australia, the United Kingdom and Canada follow at smaller volumes. This pattern tracks the jurisdictions where floating-wind demonstration and pilot-array projects have concentrated rather than where turbines are eventually deployed at scale.
US12631161B2, assigned to Aikido Technologies and published 2026-05-19, claims a method of operating a downwind floating wind turbine within a defined mean heel angle while allowing a maximum rotor misalignment from horizontal. Because the claim is built around an operating envelope tying heel angle, rotor tilt and misalignment together, rather than a fixed hull shape, it is most relevant to control-system and operating-strategy design rather than to hull geometry alone. Anyone building downwind floating turbine control logic should review its claim scope closely before finalising an operating strategy.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
