This page provides links to the linked data representation of the EPO
patent data to allow the data to be downloaded.
This data is in standardized form and can be loaded into an RDF triple store.
There are three kinds of downloads:
full dataset is a complete dataset, including patent data,
CPC data and vocabulary files. The full dataset is large and
cpc is the latest linked data representation of
the CPC taxonomy.
vocabularies are relatively small files containting
the ontologies and vocabularies defined by EPO.
The full data contains complete and up to date patent data,
CPC taxonomy and vocabulary files.
This data is updated weekly. We provide the current and the
previous weeks data identified by year and week number.
The full data is provided in
It is divided into multiple files to make it easier to download.
Each download file is a single valid N-TRIPLES file compressed
using GZIP. For each file, there is another file containing
its SHA 512 checksum.
Vocabulary files are provided in
This section provides the latest version of the vocabulary files
which may be newer than in an initial download, though changes
to these files are relatively infrequent.
