European Patent Office Boards of Appeal upholds Freia Offshore’s Tilted Wind Tower patent.

The European Patent Office (EPO) Boards of Appeal has upheld the Tilted Wind Tower (TWT) patent owned by Freia Offshore AB, an associated company of Hexicon AB (publ), dismissing the appeal brought by EnerOcean S.L. The patent is maintained as granted. The Boards of Appeal’s decision is final and cannot in practice be appealed further. The decision was handed down at oral proceedings on 2026-06-23 in EPO Boards of Appeal case T1143/24. EnerOcean had appealed an earlier ruling of the EPO Opposition Division, which had already found in favour of the patent. With the appeal now dismissed, the TWT patent remains in force across the European jurisdictions in which it is validated. The Tilted Wind Tower patent protects the core element of TwinWind, the dual-turbine floating offshore wind platform developed by Hexicon and commercialised through Freia Offshore AB. EnerOcean has challenged the patent since 2021. The ruling confirms the patent’s validity in the form in which it was granted.
