By using Devont Innovation Index Database and Patent Information Service Platform, the patent data information before 2015 was collected for both international and domestic markets. The annual development trend of screw vacuum pump industry, main patentees, main inventors, industry research and development hotspots, etc. were analyzed emphatically. Finally, the true screw was obtained. Relevant conclusions on R&D status and competitive situation of air pump industry.
Patent analysis, also known as patent intelligence analysis, is the collection of patents in a specific period of time in a technical field, and screening, statistics and research the information contained therein to form information with high value, so as to provide reference for the government, enterprises and other strategic decision-making. According to the statistics of the World Intellectual Property Organization (WIPO), 90%~95% of R&D achievements can be obtained in patent documents. If patent documents can be effectively used, R&D expenditure can be reduced by 40% and R&D time can be shortened by 60%.
Oil-free screw vacuum pump is a kind of dry vacuum pump with huge market potential, which is suitable for many fields such as semiconductor, chemical industry, pharmacy and so on. In recent years, the research and development, popularization and application of screw vacuum pump products have been developed rapidly in China. At the same time, the patent protection awareness of screw vacuum pump enterprises is constantly strengthened. However, the author finds that there are few literatures on patent analysis of screw vacuum pump industry at present, so this paper uses patent analysis method to study the development trend of screw vacuum pump industry and other related situations for reference.
