Present and Future Trends in Wind Turbine Technology

Utility grade wind turbines have come to be so technologically advanced that they have improved the cost of energy of wind sufficient to turn into a lot more mainstream than ever before and compete with today’s conventional energy sources. We’ve decided to investigate the patent landscape to determine 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 were used which covers 90 different patent authorities worldwide, including 20 countries that provide full-text file search as well as legal status information. We first identified a set of keywords that would provide an all-inclusive set of search results. We also identified patent classes to search to ensure that relevant results would not be omitted. Lastly, a set of assignees of over 100+ companies who have currently or previously produced wind turbine technology/components were searched.

Additionally, an assessment of the relevance of the patent to the industry was performed and results were classified as low, medium, medium/high, and high. The definitions of this classification method are below. The assessment of industry relevance serves the purpose of indicating the degree to which the patent owner has or is likely to assert their rights and seek … READ MORE ...
