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 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.
