Innovation serves as the primary engine driving economic development. As fundamental units of the economic society, individual enterprises' innovation investments not only underpin their long-term growth but also critically shape the global innovation landscape. Patent quantity and quality directly reflect corporate R&D innovation capabilities. However, patent quality cannot be assessed monolithically—metrics such as patent citations, patent grant ratios, technological coverage breadth, and number of patent claims all constitute evaluation criteria for patent quality.
In today's dynamic innovation environment, studying innovation through single indicators has become inadequate. More granular patent data represents an inevitable trend in academic research. CnOpenData, in collaboration with third parties, presents global patent data encompassing patent information from multiple countries, including invention patents, utility model patents, and design patents. Specifically, we categorize the data into six modules: Basic Patent Information Table, Patent Citation Table (design patents excluded), Patent Cited Table, Patent Cited by Literature Table, Patent Transaction Table, and Patent Classification Table. These modules feature comprehensive fields and logical structures, providing robust and holistic data support for this research domain.
