 The register notably provides the current legal status of European patent applications and patents, such as for instance "whether a patent application has been published, whether a patent has been granted, what the outcome of opposition proceedings was or whether a patent has been revoked".The register does not, however, contain information regarding what happens to a European patent at the national level (especially after grant, when the European patent becomes effectively a bundle of national patents in the member states of the European Patent Organisation).Since October 2011 however, its records include deep links to the corresponding records of the European patents' "national parts" in about twenty national registers (as of December 2012).
