To support the objectives of the journal, to publish new research and insights covering a broad spectrum of Intellectual Property related practices and methods, the editors, together with the team at IFI CLAIMS® Patent Services, have put together a patent research collection, publicly available and for free, to foster scientific good practice: comparability, reproducibility and repeatability of experiments and results. The World Patent Information (WPI) collection is for this reason static. It will not be updated with new data. Otherwise, changes in experimental results would be impossible to trace with confidence to the new methods being proposed and not seen as a result of changes in the dataset. The WPI collection complements existing test collections, which are vertical (one domain or one authority over many years).  Instead, the WPI collection is horizontal: it includes all technical domains from the major patenting authorities over the relatively short time span of two years.

The 1273 files in this each represent one week of publications from one authority.
