1. According to Article 12(3) and (5) RPBA 2020, a lack of or an insufficient substantiation of an amended request may lead to the non-admittance of this request. This does however not imply that the request has not been validly filed (reasons 4.2).
2. The admittance of an amended request which is not expressly substantiated pursuant to Article 12(3) RPBA 2020 is at the discretion of the Board under Article 12(5) RPBA, even if the amendments are self-explanatory (reasons 4.3.2).
3. The substantiation of an amended request under Article 12(3) RPBA 2020 includes the primary duty of the proprietor to indicate the basis for the amendments in the application as originally filed, even if no objection under Article 123(2) EPC has been previously raised (reasons 4.3.3 (a) and 4.4.5 (c)).
4. Information that can only be found in attached documents, without an explicit reference and explanation by the party, cannot be regarded as sufficient substantiation pursuant to Article 12(3) RPBA 2020 (reasons 4.4.6.(c)).
5. The discretion not to admit a request under Article 12(5) RPBA 2020 may be exercised by taking into account the extent to which a lack of or an insufficient substantiation prevents the Board and/or the other party(ies) from recognising the proprietor's intentions (reasons 4.5.1).
