Abstract： Purpose/significance： Based on the analysis of the global development of Philips PET detector patent big data information， this paper deeply studies the technical hot spots of the current development of PET detector， and probes into the patent layout and core patents of foreign key competitors. The purpose of this paper is to provide reference for the development of Chinese enterprises and the government in this field. Methods/process： The patent information retrieval and analysis platform of the State Intellectual Property Office was used to retrieve and analyze the patent information in the field of Philips PET detector. Firstly， the hot spot of Philips research was judged， and then based on the hot spot of the technology， the patent information of Philips detector was searched and analyzed by using the patent information retrieval and analysis platform of State intellectual property Office. According to Philips in the hot spot of the technology core patent mining its core patent technology， in which the core patent is based on the patent citation frequency， five bureau layout， five bureau authorization and so on. Results/conclusion： The readout chip has always been in the research and development direction of Philips， and Philips is mainly improving the TDC/ADC circuit to solve the problems of the offset of the photonic position， the limitation of the electronic characteristics of the front end and the sensitivity of the silicon photomultiplier SiPM. In solving the above problems， Chinese enterprises should pay attention to avoid the above solutions， at the same time， the offset of the position of photons is the main research and development direction， Chinese enterprises can also cooperate with them in this direction. In addition， Philips does not lack core patents in China， so Chinese enterprises should avoid the risk of infringement in research and development.
