– 
any amendments made to the claims under Art. 19 PCT (cf. item (viii) above) if the applicant wishes these amendments to form the basis of further proceedings and they are not annexed to the IPER (for instance because they were considered reversed by an amendment under Art. 34 PCT).

Rule 76.5(iv) PCT

If the applicant does not furnish the translation of any of the items (i) or (ii) above within the 31-month period, the application is deemed to be withdrawn under Rule 160(1).

Art. 24(1)(iii) or 39(2) PCT
Rule 160(1)

If the applicant does not furnish the translation of any of the items (iii) to (ix) above within the 31-month period, the EPO will invite him to furnish the translation within a two-month period from notification of the respective communication under Rule 159(1)(a). The same applies if, in the case of a correction of erroneously filed elements or parts under Rule 20.5bis(d) PCT by the receiving Office (see C-III, 1.3), translations of the erroneously filed application documents (in relation to items (i) to (iii) above) have not been filed. If the applicant does not comply with this invitation

– 
as regards items (iii) to (vii) above, the application is deemed to be withdrawn; 

Art. 24(1)(iii) or 39(2) PCT; Rule 160(1)

–
as regards translations of erroneously filed application documents (in relation to items (i) to (iii) above) in the case of a correction of erroneously filed elements or parts under Rule 20.5bis(d) PCT by the receiving Office, the application is deemed to be withdrawn;
– 
as regards the replacement sheets referred to in item (ix) above, the application is deemed to be withdrawn;

– 
as regards the replacement sheets referred to in item (viii) above, the EPO will disregard the amendments under Art. 19 PCT;

Rule 49.5(c) PCT;
Rule 3(1)

Where the application is deemed to be withdrawn under Rule 160(1), Rule 112(2) applies mutatis mutandis. The loss of rights is deemed not to have occurred if, within two months as from notification of the communication, the translation and a valid request for further processing (including the payment of the requisite fee) are filed (Art. 121 and Rule 135(1), see E‑VIII, 2).

Where an international application was filed and published in the international phase in an official language of the EPO, it is not possible to change the language of the proceedings on entry into the European phase by filing a translation of that application into either of the other two official languages of the EPO (see G 4/08). In such cases, the language of the proceedings within the meaning of Art. 14(3) remains the language in which the application was published by WIPO's International Bureau.

A translation, whether filed on entry into the European phase under Art. 153(4) or in the international phase under Rule 12.3 or 12.4 PCT, may always be brought into conformity with the application as filed. The conditions set out in A‑VII, 7, apply.
