After grant under the EPC, some states require translations - Art.65. However, National Law Table V, column 6 sometimes requires a national patent attorney to be appointed or an address for service to be provided (See for example, Ireland - "must be provided"). There is no basis in the EPC for this.
Is there a deadline and sanction for the address for service ?
Presumably it is found in national law, but is it possible to give a general rule ?
