Measurement and Comparison of Patent Quality on Typical Emerging Industries in China

We analyzed the concept of patent quality and the status quo of patent quality evaluation, designed the technical classification systems and patent retrieval strategies, set up a database of patent characteristic information on graphene industry. We constructed the patent quality evaluation system on "three dimensions — whole process" from three dimensions that included technical quality, legal quality and economic quality, and from four forming stages that included patent creation, patent application, patent examination and patent authorization. According to totality, compound growth rate, patented authorizer type, technology subfield, quality sub-dimension, etc., we systematically measured patent quality of graphene industry in 31 provinces in China, and compared different characteristics of patent quality. Our conclusions were including characteristics of patent quality in each region, region classifications based on the patent characteristics, distribution of regions with relatively high patent quality, and distribution of regions with high development potentiality for patent quality. We attempted to provide effective reference and accurate direction for further monitoring the patent quality on graphene industry in different regions, formulating policies to improve patent quality and promoting innovative development on related strategic emerging industries.
