The MAREC/IREC data set
Listed in TU Wien Research Data
MAREC/IREC: The MAtrixware REsearch Collection / The Information retrieval facility Research Collection MAREC/IREC is a static collection of over 19 million patent applications and granted patents in a unified file format normalized from EP, WO, US, and JP sources, spanning a range from 1976 to June 2008.
Description
MAREC/IREC is intended as raw material for research and evaluation in areas such as information retrieval, natural language processing or machine translation, which require large amounts of complex documents.
It allows experiments with real data on a realistic scale. The collection contains documents in several languages, the majority being English, German and French, and about half of the documents include full text. In MAREC/IREC, the documents from different countries and sources are normalized to a common XML format with a uniform patent numbering scheme and citation format.

The standardized fields include dates, countries, languages, references, person names, and companies as well as rich subject classifications. It is a comparable corpus, where many documents are available in similar versions in other languages. The 19,386,697 XML files measure a total of 621 GB.
IREC - Information retrieval facility Research Collection The MAREC original collection was missing parts of the European Granted Patents claim section (EP-B documents). An EPB_Bugfix folder existed to provide those files corrected. The IREC simply merges the original EPB folder with the EPB_Bugfix in order to provide a uniform representation.
The CLEF-IP collections have never been affected by this issue, as they were specially curated.
