An empirical study on classification of patent life patterns
摘要:With the theoretical framework of patent information life cycle, this research studies the relationship between patents’ life patterns and the technological development stages of the relevant field, using life status in patent information life cycle as the research dimension. [data] Data of patents issued in the field of wireless charging are retrieved from the United States Patent and Trademark Office Library. Citation information about these patents is also collected. [method]Analyzing the temporal citation count data of patent information, we classify the patents’ life patterns using the RSD / P classification method. [results]This study found that the emergence of different life patterns of patent information has a strong connection with the technological stage in which the patent information is located, and “Sleeping Beauty” patents have high hidden value. In the stage of technological development, attention should be paid to the identification of non-stationary patents. [implication] Rapid identification of high-value patents, i.e. patents with certain life pattern, is instrumental to accelerating the development of technologies. This study provides a viable approach for identifying high-value patents of emerging technologies through empirical research.
