Article 57
Duration of time limits 1. Where Regulation (EC) No 6/2002 or this Regulation provide for a time limit to be specified by the Office, such time limit shall, when the party concerned has its domicile or its principal place of business or an establishment within the Community, be not less than one month, or, when those conditions are not fulfilled, not less than two months, and no more than six months. The Office may, when this is appropriate under the circumstances, grant an extension of a time limit specified if such extension is requested by the party concerned and the request is submitted before the original time limit expires. 2.
