T 1403/16 Can an opponent file a request for re-establishment having not timely responded to a R.84(1) invitation

The opposition division noted that the patent in suit had lapsed in all the designated contracting states and issued a communication under R.84(1) EPC inviting the opponent to file, within two months, a request for continuation of the opposition proceedings. By mistake, the opponent's representative failed to timely file the request under R.84(1). A request for re-establishment was filed. It was argued that re-establishment should be allowed in line with the exceptions given by the Enlarged Board in G 1/86. The opposition division did not see a reason to extend the scope of G 1/86 from opposition appeal proceedings to opposition proceedings and decided to declare the re-establishment request inadmissible and to discontinue the opposition. The opponent appealed.
The Board of Appeal did not go into the issue whether the scope of re-establishment should be extended but came to the concluson that re-establishment would anyhow not apply to missing a time limit under R.84(1). Missing such a time limit does not have a direct loss as a consequence. The opposition division may decide to discontinue the opposition proceedings if no timely request is filed, but this is a separate decision. Such a decision can be appealed.
