CONCENTRATED SOLAR POWER. Latest granted patents 2016-2018. Dish/Stirling
Summary
Technologies using parabolic dish collects in combination with Stirling engines have not yet entered the energy market and are not commercially viable. Nevertheless, the high efficiency of parabolic dish concentrators of solar energy and Stirling engines cannot go unnoticed by energy producers. Sandia National Laboratories, for example, and the Swedish company Azelio are conducting excessive research in this field. Despite the fact, that commercial projects using this technology have not yet been implemented, the latest patents in this area are a reference point for monitoring latest technological trends.
A selection of patents related to Concentrated Solar Power and Dish/Stirling technology and published by patent offices around the globe in 2016-2018 is provided for review in the present bulletin. General research methodology can be found at Advanced Energy Technologies website. The present bulletin includes 138 patents, prepared by applicants from 19 countries and registered in 15 patent offices. The patent documents mention 120 applicants and 185 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 granted the largest number of patents were CNIPA (CN), USPTO (US) and EPO.
From the analysis of texts of patent documents 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 documents 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.
A list of the top 10 applicants by the number of patent documents includes Abengoa Solar New Technologies, S.A. (Spain), Galdón Cabrera Carlos (Spain), AGC Glass Europe SA (Belgium), Xiangtan Electric Manufacturing Co., Ltd (China), CSUT Changsha University of Science and Technology (China), ThyssenKrupp Steel Europe AG (Germany), Zhejiang University (China), Cleanergy AB (Sweden), Glasspoint Solar, Inc. (United States), Outokumpu Nirosta GmbH (Germany).
Data representing the share in the established intellectual property market, distribution of patents by problems, IPC sections, patent offices and technology indicators 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.
