Discussion on Analytical Method of Patent Situation in Hardware Industry

Distribution of hardware products in the international patent classification table Although the International Patent Classification (IPC) method has relatively scientific and reasonable classification methods for patent information, it involves some specific industries, especially such product categories as the hardware industry. In many cases, industries that do not have a unified and standardized industry classification currently rely solely on the International Patent Classification (IPC) method for retrieval. Obviously, the workload is large and it is inconvenient in practical use. The author believes that the analysis of the patent status of the hardware industry should be based on the characteristics of the industry and the needs of project research to be collated and analyzed, and must be selected and used in conjunction with the research object and research purpose. According to our research on the products and distribution of Nanhai hardware industry, we will compare the hardware products involved in this study (mainly the hardware products currently produced in Nanhai) with the three major classification categories (hardware, Daily hardware and mechanical hardware are classified into three levels of classification: “Hardware industry→Product classification→Specific products”. According to the international patent classification table, the “patent of hardware patent application in international patent classification” is formed as shown in Table 1. Distribution in the (IPC) table." On this basis, for each product, the use of international patent classification method for retrieval and analysis.

The empirical research of the hardware industry patent status is to further verify the operability and scientificity of the “Nanhai hardware industry Sino-foreign patent database”. According to the development status of the hardware industry at home and abroad, we use the foreign hardware industry to compare the status of the hardware patent applications of developed countries and the Chinese hardware. The status of patent applications and the application status of Nanhai Hardware patents were the subjects of research and empirical research and analysis were conducted. Domestic and foreign hardware industry patent application status and analysis According to 2002, the number of hardware patent applications of the seven countries and two organizations in the above-mentioned database was calculated according to the statistics of construction hardware, daily hardware, mechanical hardware, and the proportion of domestic and foreign hardware patents. Retrieval, aggregation and analysis.

The conclusions are as follows: 1 The total amount of hardware patents in the patents of the above-mentioned seven countries and two organizations is about 2.3 million pieces, of which, there are about 300,000 pieces of Chinese hardware patents, accounting for 12194% of the total. It shows that the number of patents for hardware technology applied at home and abroad is considerable. The patent database of the hardware industry contains a large amount of patent information that can be used and referenced by the industry. The top 3 patent applications from Japan (4317%), the United States (22107%), and China (12194%) indicate that the hardware industry in Japan, the United States, and China are more technologically innovative and have larger markets. The development of hardware technology in China also holds a certain proportion in the world. 3 The search and statistics of the patent resources in the foreign databases containing the above-mentioned six foreign and two organizational hardware patent applications indicate that the countries or organizations that receive more patent applications in the hardware industry are mainly Japan, the United States, the European Patent Office and Germany.

Hardware resources in the Chinese patent database in the hardware industry In the above-mentioned Chinese patent database, you can also see the status of the patent applications displayed in the three-level navigation. We corresponded to each specific product, searched and calculated the status of invalid patents in patent applications, the geographical distribution of patent applications, the distribution of foreign patents and applications for foreign companies or other organizations and individuals in China. Nanhai Hardware Industry Patent Application Status and Analysis According to the specific conditions of the Nanhai Hardware Industry, we distributed the status of the products corresponding to their application, the distribution in each town, the distribution status in the year 1985-2002, and the patent authorization status of Nanhai Hardware Industry ( The types of patents, legal status, etc., combined with the key enterprises and major export products of Nanhai Hardware, searched and analyzed, and compared the total amount of applications and authorizations in Guangdong Province and China, and the foreign companies’ application and authorization in China, analysis.
