   Intellectual property rights play an increasingly vital role in listed companies, serving as a key indicator for assessing core competitiveness and market control capabilities. Existing research reveals that each additional patent held by a listed company increases its market value by several million yuan. Moreover, regions with stronger intellectual property protection demonstrate a greater contribution of patent output to market capitalization.

   As part of CnOpenData’s patent series, the A-share Listed Companies Patent and Citation Data comprises three sub-tables: Patent Quantity Statistics, Patent Quality Statistics, and Patent Details. This dataset not only evaluates the patent performance of A-share listed companies from both quantitative and qualitative perspectives but also encompasses comprehensive patent information covering listed companies and their subsidiaries, affiliated companies, and joint ventures. It serves as a significant complement to CnOpenData’s patent series database.

   The Patent Quantity Statistics and Patent Quality Statistics tables are subdivided based on patent applications and patent grants, respectively. The Patent Quality Statistics table further categorizes patents into three types: inventions, utility models, and designs. Citation and cited information is presented in the Patent Details section, organized into six modules: Invention Applications, Invention Grants, Utility Model Applications, Utility Model Grants, Design Applications, and Design Grants. Each module includes four tables: Basic Information, Citations, Cited-by, and Transaction Records (note: design patents lack citation, cited-by, and transaction tables).


Time Coverage
