LOD from the European Patent Office: Patent Information and Technical Classification


The European Patent Office (EPO) provides patent protection for inventions in up to 40 European countries on the basis of one single application. The EPO also publishes these patents and make them available to the public in a variety of formats: via online tools, web services or bulk data. To be prepared for the future and make patent information useful for as many user groups as possible, in spring 2018 the meta-data (aka bibliographic data) of all EP patents since 1978 has been made available in the data set “Linked open EP data”. This product consists of about 650 million triples and is freely available with an open license.
This data set also includes the extensive Cooperative Patent Classification CPC, which covers the complete technical domain and which is used to classify all patents for to facilitate retrieval.
