摘? 要：[目的/意義]文章通過飛利浦PET探測器專利大數據情報的全球發展動態進行分析，深入研究PET探測器當前發展的技術熱點，窺探國外重點競爭對手專利布局以及核心專利，旨在為我國企業以及政府在該領域的發展提供參考。[方法/過程]利用國家知識產權局專利信息檢索和分析平臺對飛利浦PET探測器領域專利情報進行檢索分析，首先判斷當前飛利浦研究的技術熱點，隨后基于該技術熱點，根據飛利浦在該技術熱點的核心專利挖掘其核心專利技術，其中核心專利基于專利被引頻次、五局布局情況、五局授權情況等確定。[結果/結論]讀出芯片一直是飛利浦致力研發的方向，同時飛利浦主要在TDC/ADC電路上改進，以解決光子位置的偏移，前端電子特性的限制和硅光電倍增管SiPM的敏感性的問題，中國企業在解決上述問題時，應注意避免上述解決方案，同時，光子位置的偏移是其主要的研發方向，中國企業也可在該方向上與其合作。另外，飛利浦不乏在中國布局的核心專利，中國企業在研發時應注意規避侵權風險。

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.
