In a collaborative effort by the European Patent Office (EPO) and the International Renewable Energy Agency (IRENA), this patent insight report examines the global evolution of patent filings published between 2002 and 2022 in the domain of offshore wind energy.

Patent filing statistics provide insightful indicators for measuring and examining innovation, commercialisation and knowledge transfer trends across international markets. They also provide meaningful information on changes in technology trends and make it easier to identify new players or consolidation efforts. All in all, this report aims to shed light on how key technological challenges are being addressed via innovation.

Using a proven EPO data analysis methodology, this report’s findings consider information from roughly 17,000 patents (from the EPO’s patent database). These patents cover inventions related to offshore wind energy, including key technology concept groupings such as: fixed and floating foundations, towers, mechanical power transmission, blades and rotors, hybrid systems, energy storage, and grids and submarine cables.
