Patent technology can reflect the current situation and process of innovation and development in a certain technology field and has become an important source of competitive intelligence. The paper focuses on patent technology of metallocene catalyst
and uses the Derwent Innovation patent search platform to analyze the curve of metallocene catalyst patent technology. Focusing on the analysis of the competitive situation of metallocene catalyst patents in different countries in the past 10 years
through the patent map technology
showing the hot topics
and combining the incopat patent value evaluation model to analyze the distribution characteristics of high-value patents of metallocene catalysts. It was found that the United States and Japan are producers of high-value patents on metallocene catalysts and has a strong sense of patent layout. China has a place in high-value patents about new performance polyolefins
but the technology is mainly concentrated in college and research institutes
and the application of technology is in a weak position.
