Period for retroactive payment of renewal fees which would have become due during the period between revocation of the patent and re-opening of the proceedings before the boards of appeal

6 months


No express legal provision in PA or PR but, once the Irish Office has been informed of the Enlarged Board's decision to set aside the revocation of a European patent and re-open the appeal proceedings, the practice is to allow the patent proprietor a period of up to 6 months to pay all renewal fees that would have fallen due in the intervening period.
