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
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.
