Abstract:In the field of architecture, the security requirements of access control systems are getting higher and higher, and related enterprises and scholars are studying more and more security technologies for access control systems, but the research content is mainly specific access control technology. With the increasingly fierce competition in technology, in order to strategically grasp the direction of technological innovation, companies need to carry out research on patent strategy, and the key is patent analysis. Technology life cycle analysis is an important part of patent analysis, while patent indicator method and S curve mathematical model method are two important methods to analyze the life cycle. This paper combines the patent index method and the S-curve mathematical model method, analyzes the life cycle of the access control system security technology, and reveals the current development and future development trend of China's access control system security technology. Finally, the corresponding patent strategy was provided for related companies.
