Classification search

Classification search is a powerful tool for you if you need to retrieve patent publications in a particular technical area. Classification search in Espacenet helps you to find suitable classification symbols for your search, and then to apply in the search itself.

Global Dossier

Applicants often file patent applications for the same invention at multiple patent offices. Global Dossier brings these documents together in one place, to give you access to the correspondence (or “file wrapper”) between applicants/attorneys and the offices concerned for Canadian, Chinese, European, Japanese, Korean, US and PCT applications. It also offers you automatic machine translations of Chinese, Japanese and Korean documents into English.

Global Dossier is available from the European Patent Register and Espacenet.

Common Citation Document

The Common Citation Document (CCD) tool provides a single point of access to citation data for the patent applications of the largest five IP offices (IP5).

This tool consolidates the prior art cited by all participating offices for the family members of a patent application, showing the search results from different offices on a single page.
