Our new research report has catalogued over 27,500 global patent filings related to horizontal-axis, utility-scale wind turbine technology. The report shows only about 1% of issued patents are a high impact on the products and services currently offered by the industry as a whole, with another 7% which may become relevant in the future depending on technology adoption. The remaining 92% of global patent filings are merely providing companies with basic defensive IP protection on their own distinct technologies, products and service offerings. Nevertheless, patent filings are up sharply across the entire wind industry since 2006, largely due to an increased spend on research and development as well as intellectual property (IP) protection.
