1.16. Different sets of claims for different contracting states

In T 658/03 the board stated that any change of attribution of claimed subject-matter in an application or patent having different (sets of) claims for different contracting states, to a contracting state under which that subject-matter was not previously included, amounted to an amendment within the meaning of Art. 123 EPC 1973. Such an amendment was subject, in principle, to full examination as to its conformity with the requirements of the Convention.
