WIND ENERGY. Latest granted patents 2014-2016. Control and power production units
Summary
Highly sensitive systems for monitoring the state of equipment elements of wind turbines can achieve high productivity, ensure durability and reliability of their operation, and at the same time reduce the turnaround time of maintenance. Anemometers, pitch and yaw systems track the angle of attack of key wind flow parameters and adjust the orientation and pitch of the blades accordingly, minimizing energy losses. In gusty and strong winds, such systems allow you to control the power of the installation until it is completely turned off. Therefore, in order to ensure the highest level of efficiency and safety, technical improvements in the field of control and power production units are the primary concern of researchers and engineers. This patent statistics bulletin provides an analysis of the latest patents in the field and can serve as an additional guideline to track trends and industry leaders.
The present bulletin reviews patents granted by patent offices around the globe in 2014-2016 in the field related to wind power. General research methodology can be found on the Advanced Energy Technologies website. 1899 patent documents from 25 patent offices around the world are represented in the bulletin. In total, 825 applicants from 26 countries and 816 subgroups of the International Patent Classification are mentioned.
Key Highlights
The bulletin contains statistical data on the distribution of patent documents by years, by patent offices and by applicant countries, applicant-related data (residents and non-residents), data on the most frequently mentioned International Patent Classification divisions (sections, classes, subclasses, groups, and subgroups). The top three patent offices that granted the largest number of patents were EPO, USPTO (US) and CNIPA (CN).
For each of the patent documents selected for the examination in the present bulletin the characteristics of unified indicators were preliminary defined, they include: technical problems, types of inventive solutions employed, belonging to one or other technological segment. This allows the internal content for each of the indicators in the aggregate array of documents to be visualized, for instance, to define the sequence and proportional correlation of technical problems the inventive solutions disclosed in the texts aim to solve. A list of the top 10 groups consisting of patent documents with identical unified indicators contains ID numbers and applicant names of respective documents; the groups are sorted by the number of patent documents.
A list of the top 10 applicants by the number of patent documents includes Vestas Wind Systems A/S (Denmark), Wobben Properties GmbH (Germany), Siemens AG (Germany), General Electric (USA), Mitsubishi Heavy Industries, Ltd. (Japan), Wobben Aloys (Germany), Senvion S.A. (Germany), Gamesa Innovation & Technology S.L. (Spain), NORDEX ENERGY GMBH (Germany), Repower System AG (Germany). Data representing the share in the established intellectual property market, distribution of patent by problems, IPC sections, patent offices is provided in the form of tables and diagrams for them.
The prominent documents pages contain the top 10 patents with the highest bibliographical rating, the most extensive coverage of IPC sections, and the shortest patent pending time.
The conclusive part of the bulletin represents the lists of all of the documents reviewed, arranged by the top 10 groups of patent documents with identical unified indicators and by patent offices with the indication of the ID numbers of the granted patents.
Who needs this bulletin?
The proposed patent statistics bulletin allows the existing trends in the intellectual property market of the specified industrial sector to be timely traced, as well as the possibility of acquiring a carefully selected list of patent documents fully corresponding to the specified subject. The bulletin can be useful for inventors, engineers, scientific workers, and business representatives, who are focused on the development of wind energy technologies.
