CONCENTRATED SOLAR POWER. Latest published applications 2017-2019. Optics
Summary
Optical elements take centre stage in harvesting solar energy as they are responsible for the efficiency of sun concentration and its conversion into electricity. Solar optics usually consists of lenses and mirrors, and their reliability and reflectance spectra depend to a greater extent on the composition of specific materials and coatings applied. In order to achieve low-levelled energy cost and overcome various construction limitations, optical elements are constantly in a stage of ongoing development, where new designs and materials are created. Research concentrates on enhancing of the reflectiveness and resistance properties, reducing manufacturing costs, improving of installation and maintenance. The latest patent applications presented in this statistical bulletin give interested parties an insight into the current strategies in this field.
The present bulletin reviews patent applications registered by patent offices around the globe in 2017-2019 in the field related to Optics in Concentrated Solar Power. General research methodology can be found on the Advanced Energy Technologies website. 620 patent documents from 28 patent offices around the world are represented in the bulletin. In total, 351 applicants from 31 countries and 481 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 registered the largest number of patent applications were CNIPA (CN), USPTO (US) and WIPO.
Based on the analysis of each of the patent applications, 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.
A list of the top 10 applicants by the number of patent documents includes Sumitomo Electric Industries, Ltd. (JP), 3M Innovative Properties Company (US), Commissariat à l'énergie atomique et aux énergies alternatives (FR), Bolymedia Holdings Co. Ltd (US), Saint-Augustin Canada Electric Inc. (CA), Fundación Tekniker (ES), Luxembourg Institute of Science and Technology (LU), Zhejiang Supcon Solar Energy Technology Co., Ltd. (CN), Fund Cener Ciemat (ES) and Insolight SA (CH). Data representing the share in the established intellectual property market, distribution of applications by problems, IPC sections, patent offices and technology indicators is provided in the form of tables and diagrams for them.
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.
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 registered patent applications.
