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.
