The reasoning accompanying amendments or corrections filed in response to the Rule 71(3) communication should indicate respectively:
If, within the period under Rule 71(3), the applicant files amendments or corrections which 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 lack of any reasoning means that such amendments or corrections are more likely to lead to a resumption of the examination procedure (see C‑V, 4.7).
