WIND ENERGY. Latest published applications 2015-2017. Offshore Wind Turbine
Summary
Offshore wind energy is one of the most promising areas of green energy, which can significantly increase the share of domestic energy production. The countries of Northern Europe, where offshore stations are most widely used, are leaders in the technological improvement of both stationary and floating offshore wind turbines. According to the forecast of IRENA, in its dynamic scenario, offshore wind energy capacities can increase to more than 500 GW by 2050. This bulletin provides up-to-date information on recent patent applications in the field of offshore wind turbines and allows you to keep abreast of the main technological trends in this area of energy.
A selection of patent applications related to offshore wind turbines and published by patent offices around the globe in 2015-2017 is provided for review in the present bulletin. General research methodology can be found at the Advanced Energy Technologies website. The present bulletin includes 1152 patent applications, prepared by applicants from 22 countries and registered in 29 patent offices. The patent documents mention 319 applicants and 528 IPC subgroups.
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 registered the largest number of patent applications were EPO, USPTO (US) and CNIPA (CN).
From the analysis of texts of patent applications presented in this bulletin, detailed information is extracted for each of the unified indicators, which include: technical problems, types of inventive solutions employed, belonging of a patent document to one or other technological segment. The results of the statistical processing of this data for the entire array of the patent applications examined are summarized in the correspondingly-named diagrams and tables. In addition to that, a list of the top 10 groups of patent documents with identical unified indicators is provided, where the groups are sorted by the number of patent documents and include ID numbers and applicant names of the documents.
Data is provided for each of the top 10 applicants, leading in terms of the number of published patent documents among the ones examined in the bulletin, illustrating their share in the established intellectual property market, distribution of documents by problems, IPC sections, patent offices and technology indicators. Representatives of Denmark and Germany prevail among the patenting leaders in the examined period of time. These leaders include: Vestas Wind Systems A/S (Denmark), MHI Vestas Offshore Wind A/S (Denmark), Siemens AG (Germany), Mitsubishi Heavy Industries, Ltd. (Japan), University of Maine (the USA), Areva Wind GmbH (Germany), Hitachi, Ltd. (Japan), Envision Energy (Denmark) APS, Alstom Renewable Technologies (France), Senvion S.A.(Germany).
The bulletin contains lists of the top 10 prominent documents having the highest bibliographical rating, the most extensive coverage of IPC sections, and those not being part a of patent family.
A list 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 registered patent applications are provided in the conclusive part of the bulletin.
Who needs this bulletin?
The statistics bulletin under examination serves as one of the variants to monitor advanced technical achievements in the specified industrial sector. The statistical data, rating evaluations and carefully selected patent documents provided in the bulletin can be of interest for inventors, students and educators, engineers, as well as for businessmen and investors, who in one way or another are concerned with the problems of the development of wind energy production technologies.
