Wind tower power generation patent

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.

Are floating foundations the future of wind power?

Market trends indicate a growing interest in developing floating foundations given their potential for siting turbines in deeper waters with abundant wind potential. This is confirmed by patent data, which shows that industry players are innovating in this technology area. Tower and blade designs to reduce steel demand and enhance sustainability.

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.

What percentage of wind energy patent families are international?

Twenty-seven percent of all ofshore wind energy patent families are international patent families (IPFs) i.e. excluding single domestic filings. More specifically 79% of the total patent families developed by European countries are IPFs, as- are 64% by the United States of America. Four percent of Chinese patent families are international.
