The Catalogue of Differing Practices (CDP) has been updated

The Catalogue of Differing Practices (CDP) provides information on the differences in practice relating, in particular, to claim interpretation, novelty, and inventive step at the IP5 offices (EPO, JPO, KIPO, SIPO, USPTO). The remaining differences in substantive practice between the five largest IP offices in a number of selected items are described and combined into one reference document.  

The 2012 update of the Catalogue is now available for download at:
