Nipper's Patent Law Blog pointed me to a very interesting paper: The JP-PTO, the AIPLA, the JIPA (Japan Intelletual Property Association) and the UNICE (European industry group) have issued a joint resolution recommending reducing patent law harmonization issues to: (1) a first-to-file system of priority, (2) an international grace period, (3) a definition of prior art having no geographic limitations, and (4) a definition of how and when pending, published patent applications are to be used as prior art. The chances for all further ambitions of harmonisation of the substantive patent law seem to be dim.
