3. Expenses that may be apportioned
3.3. Procedure for fixing costs
Under R. 88(2) EPC, costs to be paid under a final decision apportioning them will be fixed only at the request of the entitled party. The request is not subject to a time limit. The request must be accompanied by a bill of costs and supporting evidence. Costs may be fixed once they have been established as credible. The board in T 475/07 exceptionally took the view that a detailed cost calculation was superfluous. It worked on the assumption that the representative could calculate on the basis of one day for preparing the additional oral proceedings and one day for attending them. The cost estimate of EUR 2 300 thus seemed credible.
Under R. 88(3) EPC, a request for a decision by the opposition division may be filed within one month of the communication on the fixing of costs. It must be filed in writing and state the grounds on which it is based. It is not deemed to be filed until the fee prescribed in Art. 2(1) item 16 RFees has been paid.
In T 668/99 the question was raised as to whether the prohibition of reformatio in peius also applied if the proceedings were not referred to a higher level of jurisdiction but were continued within the same level of jurisdiction, as was the case with a legal remedy against the fixing of the costs by the opposition division registry. The board recalled that an appeal and a request for an opposition division decision have far more similarities (suspensive and devolutive effect) than differences, and so the position of the sole requester is comparable to that of the sole appellant. The board was therefore satisfied that the prohibition of reformatio in peius also had to apply to a request under Art. 104(2), second sentence, EPC 1973.
Where the boards of appeal have to rule on the apportionment of costs, they have the power under Art. 104 EPC and Art. 111(1) EPC, and having due regard to Art. 113(1) EPC, not only to apportion but also to fix the costs (see e.g. T 934/91, OJ 1994, 184; T 323/89, OJ 1992, 169; T 930/92, OJ 1996, 191 applying the EPC 1973; for a more recent decision in which the board fixed the amount of the costs, see T 1663/13). The scope of the apportionment depends on the specific circumstances of the individual case. The party to the proceedings who caused the additional costs may be ordered to pay all or a part of those costs (T 323/89, OJ 1992, 169).
