WIPO Index of Patent Systems

According to their website, the "WIPO Index of Patent Systems" is a tool for helping users of patent statistics understand the impact of differences between patent systems on the interpretation of patent statistics. The Index is based on the results of a survey sent by WIPO in March 2005 to all its Members States. The resulting country profiles reflect the status of the patent system in each country as of May 2005 and will be regularly updated as more information becomes available.
