WIND ENERGY. Latest published applications 2015-2017. Control and power production units
Summary
Today, wind energy occupies a leading position in the balance of electricity production in several countries of the world, and this trend is steadily expanding. Currently implemented technologies for converting wind energy into forms familiar to humans accumulate the latest achievements of various technical disciplines. Thus, a modern wind farm is equipped with highly sensitive instruments to track the direction and speed of the wind. Anemometers, yaw systems, as well as pitch systems allow you to effectively control input parameters and control power generation, depending on the prevailing environmental conditions. Modern materials used to manufacture turbine components allow it to operate even in adverse weather conditions. The submitted patent statistics bulletin contains information on recent patent applications and may be useful to researchers, inventors and maintenance engineers specializing in modern energy technologies.
The present bulletin reviews patent applications granted by patent offices around the globe in 2015-2017 in the field related to control and power production units of wind power plants. General research methodology can be found on the Advanced Energy Technologies website. 3684 patent documents from 33 patent offices around the world are represented in the bulletin. In total, 577 applicants from 32 countries and 1034 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 patent applications were USPTO (US), EPO 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 Wobben Properties GmbH (Germany), Vestas Wind Systems A/S (Denmark), General Electric (USA), Siemens AG (Germany), Mitsubishi Heavy Industries, Ltd. (Japan), Hitachi, Ltd. (Japan), Senvion Deutschland GmbH (Germany), Gamesa Innovation & Technology S.L. (Spain), Beijing Goldwind Science & Creation Windpower Equipment Co Ltd (China), Doosan Heavy Industries & Construction (South Korea). Data representing the share in the established intellectual property market, distribution of documents 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 patent applications with the highest bibliographical rating, the most extensive coverage of IPC sections, and top prominent single applications.
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 power.
