Research on the development trend of spectrometer technology based on patent analysis

Search on patent applications for spectrometer technology was conducted on a global scale, analyzing the development lifecycle, main applicants, technological development direction, and key patents of spectrometer technology. From the results, it can be seen that the spectrometer technology has gone through four stages, namely the technology start-up period, slow development period, rapid growth period, and technology maturity period. Patent technologies are mainly concentrated in categories such as G01N21, G01J3, and G01N23. Overall, the research focus of spectrometer technology is to improve the convenience of detection and the accuracy of detection results. Research on improving the reliability and stability of spectrometers, expanding the technology and applications of optical rotation spectrometers, and miniaturizing inductively coupled spectrometers can be further implemented. Through the study of the main applicants’ patent technology and key patents, it is recommended that relevant Chinese enterprises conduct technological exploration in Raman spectrometers, laser-induced breakdown spectrometers, and inductively coupled spectrometers, and pay more attention to the layout of patents.
