Current and Future Trends in Wind Turbine Technology – Results of a Patent Landscaping Exercise

Utility grade wind turbines have become so technologically advanced that they have improved the cost of energy of wind enough to become more mainstream than ever before and compete with todays conventional energy sources. We have decided to conduct an investigation of the patent landscape to see what technological trends have emerged thus far and what we might be able to infer for the future direction of wind turbine technology. At this time, the assessment was limited to the most prevalent sector of wind turbine technology utility grade, horizontal axis wind turbines.
The search was conducted utilizing a comprehensive approach, as well as thorough reading and examination of results. A patent database and search portal was used which covers 90 different patent authorities worldwide, including 20 countries which provide full-text file search as well as legal status information. We first identified a set of keywords which would provide an all-inclusive …
