CONCENTRATED SOLAR POWER. Latest granted patents 2014-2016. Dish/Stirling
Summary
The efficiency of parabolic dish collects can consistently exceed 30%, and in combination with Stirling engines they form a unique heat engine which has found application in various fields of technology, including power generation. Intensive research to test this technology is being conducted in different countries. Among the leaders in this area it is necessary to highlight Sandia National Laboratories or, for example, the Swedish company Azelio. However, commercial projects using this technology have not yet been implemented. This is due, among other things, to an insufficient number of effective engineering solutions, which could possibly be found in the latest patent documents.
The proposed bulletin is dedicated to Concentrated Solar Power and the Dish/Stirling technologies and includes patents published in 2014-2016. Research methodology is available at Advanced Energy Technologies website. The patent bulletin includes 149 patent documents that were granted in 17 patent offices around the world to 162 applicants from 20 countries participated in the development of the inventions. 161 subgroups of the International Patent Classification were encountered in the patent documents.
Key Highlights
The bulletin provides general statistical figures, including the overall 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 most popular patent offices among the applicants were: USPTO (US), CNIPA (CN), EPO, JPO (JP), OEPM(SP).
Based on the analysis of each of the patents, internal characteristics of unified indicators (technical problems, types of inventive solutions, belonging to one or other technological segment) were found, which allowed specific features for each of the indicators for the entire array of documents to be defined, for instance, to define the leading problems or technical solution types that were disclosed by the inventors the most. Document lists are provided for the ten most popular groups of patent documents with identical unified indicators, including their ID numbers and applicant names.
The following information can be found for the top 10 applicants: breakdown of patents by problems, IPC sections, patent offices, as well as the estimation of their share in the established intellectual property market. The 10 leading applicants by the number of patent documents were: Abengoa Solar New Technologies, S.A. (Spain), Yeda Research and Development Co., Ltd. (Israel), AGC Glass Europe SA (Belgium), Wuhan Kaidi Engineering Technology Research General Institute Co., Ltd. (China), Abengoa Solar Inc. (United States), Airlight Energy IP SA (China), Cosijns Bruno (Belgium), ISIS Innovation, Ltd. (United Kingdom), Ventelon Lionel (Belgium), Sunrise Csp Pty Ltd (Australia).
The bulletin contains lists of the top 10 prominent patents having the highest bibliographical rating, the most extensive coverage of IPC sections, the shortest patent pending time.
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 granted patents 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 solar energy production technologies.
