About this data
<p align="justify">This dataset provides indicators on total and environment-related patents in Functional Urban Areas (FUAs). The indicator is defined as the fractional count of (environment-related) patent applications.</p> <h3>Data sources and methodology</h3> <p align="justify">The indicator uses patent applications filled under the Patent Cooperation Treaty (PCT) at the World International Property Organisation (WIPO) from the OECD, STI Micro-data Lab Intellectual Property Database, <a href="http://oe.cd/ipstats">http://oe.cd/ipstats</a>. <br /><br /> Patents are allocated to FUAs based on the postal addresses of inventors.
