4.3 Amendments or corrections should be reasoned 

The reasoning accompanying amendments or corrections filed in response to the Rule 71(3) communication should indicate respectively:

– why the applicant considers that the amended application documents comply with the EPC, in particular the patentability requirements, Art. 123(2) and Art. 84

– why the applicant considers that the errors and their proposed corrections are evident according to Rule 139.

If, within the period under Rule 71(3), the applicant files amendments or corrections that are not reasoned, no payment of the fee for grant and publishing or claims fees is necessary, nor is the filing of translations (see C‑V, 4.1). However, the absence of any reasoning means that such amendments or corrections are more likely to result in a resumption of the examination procedure (see C‑V, 4.7).
