The patent application for scroll compressors began to grow, and from the year to the year, the number of patent applications reached a peak. The working process of the scroll compressor mainly depends on the change of the volume, and the change of the volume depends on the profile design. At present, the main types of wires used are single-type wires, modified combination wires, and general-purpose wires. The scroll compressor will gradually develop to higher pressure and higher power, and its application range will be further expanded, especially in specific occasions with high environmental protection requirements. According to statistics, the technical information recorded in the patents accounts for the entire technical information and the patent information is one year earlier than the information provided by the general technical publications, and the information is informative.
The statistics and investigation of compressor patent information provide many convenient conditions for the advanced stage of imitation technology of compressor technology diffusion. There is still a big gap between China's compressor patent field and developed countries. In terms of main performance, some enterprises have weak patent awareness. A considerable number of domestic enterprises are slow to respond to high-tech wars from abroad, as well as compressors.
The annual application for invention patents of thousands of compressor companies in China is only equivalent to the annual application volume of a large Japanese and Korean company. Many companies still have not applied for a patent yet, so they are more and more agents of foreign compressors. Not an independent research and development center. The quality of patents to be applied still needs to increase the proportion of the number of invention patent applications in a country to the total number of patent applications, and the higher the quality of patents. Japan’s invention patents in China’s application for compressor patents account for more than 93 patent applications in Japan. Similarly, South Korea accounts for more than 9%, and the United States accounts for more than US%, while China only accounts for about the total amount of patents in China. Explain from such a problem that the knowledge content of foreign patent applications in China is relatively high, revealing that they want to achieve the purpose of occupying the Chinese market through the monopoly of advanced technology.
