What are the different types of wind energy patents?

These patents cover inventions related to ofshore 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.

When did wind energy technology become a patented technology?

Following an initial phase marked by limited patent filings, the patenting activity in ofshore wind energy technologies experienced a notable surge starting in 2006. Subsequently, a period of consistent annual expansion persisted until 2012.

How many wind energy patents are there?

However, it is worth noting that patent filings specifically classified as “ofshore” are too few to conduct meaningful analysis, so we expanded the search to include all wind energy patents. Between 2002 and 2022, the number of patent filings covering these two technologies increased by a factor of fourteen.

Which countries patent wind power?

Wind power has seen an increase in worldwide patenting activity between 2001 and 2018. The most prolific patent filers worldwide are the State Grid Corporation (China), General Electric (US) and Vestas (Denmark). Our research shows that the UK is more specialised in wind power compared to other European nations.

Which country patents the most offshore wind power?

Of the top ten patenting countries, our research shows that the UK is the most specialised country for offshore wind power patenting. This is consistent with reports that the UK is the global leader in offshore wind, with more capacity installed than any other country.

How many ofshore wind energy patents are there?

This study identifies approximately 17 000 patent families related to ofshore wind energy technologies published between 2002 and 2022, as well as revealing a significant surge from 2015 onwards. European countries, particularly Denmark and Germany, have taken the lead in generating inventions.
