Floating offshore wind platform patents: who holds station-keeping and dynamic cable claims
One assignee leads with 12 records, while the ranked field of 14 companies drops to single-digit counts by fifth place, pointing to a concentrated core with a long tail. Activity starts from a single 2017 filing and builds toward a peak of 6 records in 2022, with 2026 shown as a partial year. Treat the tail end of this curve as a floor, not a ceiling — publication lag means recent filings are still arriving in the record.

Common questions on floating wind platform patents
Who holds the most patents on floating offshore wind platforms?
Within this 40-record dataset, one assignee leads with 12 records, well ahead of the rest of the ranked field of 14 companies. Filing counts drop off quickly after that leader — fifth place holds 4 records and tenth place holds 2 — which points to a concentrated core of activity around one company's platform and station-keeping designs, with a long tail of companies and individual inventors holding smaller, more specific claim positions. Because this reflects a targeted search string rather than the entire floating wind field, it should be read as a picture of this technical niche, not of the industry overall.
What patent classes cover floating wind mooring and station-keeping technology?
The dominant IPC subclass is B63B, ships and marine vessels, which appears in 85.0% of the 40 records — meaning most inventions are framed around the floating hull or vessel structure itself. E02B (hydraulic and waterway engineering) and B65D (containers and packaging) each cover 17.5% of records, E21B (earth and rock drilling, relevant to mooring anchors) covers 15.0%, and F16F (springs and dampers) and B63H (propulsion and steering) trail under 10%. Since records often carry multiple classes, these shares add up to more than 100% of the record total.
How many patents exist on dynamic cables for floating wind turbines?
This dataset does not break dynamic cable filings out as a separate count, but the representative record in the set, US20240336333A1 from Kongsberg Maritime, is specifically directed at dynamic cable pull-in during installation. Dynamic cable design is one of the search terms underlying the full 40-record set, alongside mooring line design, tow-out installation and wave-induced fatigue, so cable-specific filings sit within that broader total rather than as an isolated bucket.
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.
