The new revisions, which were already published on 18 April 2008, will be effective from 1 April 2009. A major change is an extension of the time limit for filing an appeal against the decision of refusal from 30 days to three months. Further changes include better protection for the licensee in the case of a non-exclusive licence, especially at the application stage of a patent.
