This is the homepage of the WIPO automated categorization datasets. We provide information about the datasets' contents, how get access and links to various relevant background sources of information.

We are currently freely distributing two collections of XML documents that have been manually classified in a complex hierarchical taxonomy known as the International Patent Classification (IPC):

  1. WIPO-alpha: containing over 75,000 patent documents in English.

  2. WIPO-de: containing over 110,000 patent documents in German.

These data collections are made available to the community for research purposes. In this way, we specifically aim to encourage research into the automated categorization of patent documents. Users of the collections are requested to communicate their results to WIPO.

Full details about the content of the WIPO-alpha dataset is found in the WIPO-alpha readme.
