An extension can no longer be requested once a period has expired (
J 7/81, OJ 1983, 89). However, even
Art. 121(1) EPC 1973 provided that applicants could request further processing of a European patent application if their application was to be refused, had been refused or was deemed to be withdrawn following failure to reply within a time limit set by the EPO. The new version of
Art. 121 EPC now broadens the scope of application of further processing and makes it the
standard legal remedy in cases of failure to observe time limits in the European patent grant procedure and related ex-parte appeal proceedings, irrespective of whether the time limits are set by the EPO or are specified in the Convention or Implementing Regulations, and irrespective of whether the legal consequence is the loss of the application or merely a partial loss of rights. In some cases it therefore replaces the re-establishment of rights, which had proved to be too complex and unwieldy (MR/2/00, p. 157). In other cases it replaces the implementing and fee-related rules established to provide a remedy where the scope of application of further processing and re-establishment of rights had proved to be too restrictive (especially
R. 85a and
b EPC 1973).
