Keywords: Adaptation of the description after a decision to maintain the patent in amended form - consistent with the amended set of claims (yes)
Catchwords:

Rule 57a EPC establishes a limit to the amendments which can be made to the patent in suit, namely the amendments must be occasioned by grounds of opposition specified in Article 100 EPC, even if the respective ground has not been invoked by the opponent.

Article 84 and Rule 57a EPC are the two provisions which must guide the Proprietor of the patent when he is invited by the Opposition Division to adapt the description. In other words, the amendments must be appropriate and necessary, and nothing more (see point 3 of the reasons).
