OECD Patent Databases

The OECD Patent Database was set up to develop patent indicators that are suitable for statistical analysis and that can help address S&T policy issues. The Patent Database covers data on patent applications to the European Patent Office (EPO), the US Patent and Trademark Office (USPTO), patent applications filed under the Patent Co-operation Treaty (PCT) that designate the EPO, as well as Triadic patent families. Data mainly derives from the latest version of the EPO’s Worldwide Patent Statistical Database (PATSTAT).
