Unity is assessed in the same way in the PCT and European procedures. However, the consequences of a finding of lack of unity at the search and/or the international preliminary examination stages are different under the PCT, as are the actions to be taken by the examiner. In particular, the applicant may be asked to pay additional search and/or examination fees and he may do so under protest.
Furthermore, divisional applications are not allowed under the PCT.
