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.

10. Lack of unity during search

In many and probably most instances, lack of unity will have been noted and reported upon by the Search Division which will have drawn up a partial search report based on those parts of the application relating to the invention, or unified linked group of inventions, first mentioned in the claims. The Search Division may neither refuse the application for lack of unity nor require limitation of the claims, but must inform the applicant that, if the search report is to be drawn up to cover those inventions present other than the first mentioned, then further search fees must be paid within two months.
