Late-filed request - admitted in first-instance proceedings (no)
Late-filed request - error in use of discretion at first instance (no)
Late-filed request - circumstances of appeal case justify admittance (no) - Catchword
- There is no established principle that submissions filed before the date set under Rule 116 EPC are generally admissible, just as there is no principle saying that a submission filed after that date is automatically inadmissible.
It is rather established case law that the opposition division has a discretion (not) to admit amendments filed after the period specified in the communication under Rule 79(1) EPC (see the Case Law Book, 11th edition, IV-C 5.1.4.a) and b)).
