What time limits apply to an appeal?
Notice of appeal must be filed within two months of notification of the decision of the department of first instance. Notice of appeal is not deemed to have been filed until the appeal fee has been paid.
A statement setting out the grounds of appeal must be filed within four months of notification of the decision of the department of first instance.
Subject to very specific requirements, an applicant or patent proprietor who has missed the above-mentioned time limits can request re-establishment of rights. Opponents can only request re-establishment in respect of the time limit for filing the statement of grounds of appeal (see decision G 1/86).
