According to
Art. 123(2) EPC the European patent application or the European patent may not be amended in such a way that it contains subject-matter which extends beyond the content of the application as filed. The revision of the EPC has introduced a purely editorial change to the wording of
Art. 123(2) EPC to bring it into line with
Art. 123(1) EPC. However,
Art. 123(2) EPC 1973 and
Art. 123(2) EPC are substantively the same.
