1.2 Grant and publishing fee 

The communication under Rule 71(3) also invites the applicant to pay the fee for grant and publishing within a non-extendable four-month period. For European patent applications filed before 1 April 2009 and international applications entering the regional phase before that date, the fee for grant and printing may include an element depending on the number of pages, but for applications filed or entering the regional phase on or after that date, this additional element is payable as part of the filing fee (see A‑III, 13.2).
