This revised version of the Guidelines for Examination will apply as from 1 November 2015. Until then, the September 2014 edition of the Guidelines remains valid.

3.1 Relation to unity in search; limitation to searched invention

An objection of lack of unity of invention, if applicable, should already have been raised at the search stage. If such an objection was not raised, but the Examining Division nevertheless considers that the requirements of Art. 82 are not met, the question of lack of unity will be addressed as early as possible during examination.
