Friday, October 02, 2015 T 595/11: underpayment of appeal fee and still admissable?

A 20% reduced appeal fee was paid by the Appellant (patent owner) who filed a notice of appeal in Dutch, while the patent owner is a legal person in Switzerland. The EPO communicated the file number to the Appellant and the Respondent (opponent) and indicated that the case was referred to a specific Board without any further comments. Later, when the respondent informed the Board that the Appellant was not entitled to the fee reduction, the Appellant paid the remaining portion of the fee and requested that the EPO to accept the late payment of the full appeal fee through the application of the principle of good faith (according to G2/97: the principle of the protection of legitimate expectations). In this case the Board discusses whether the Appellant could have expected that the EPO checked the entitlement to the fee reduction early enough such that the Appellant could have remedied the Appeal, for example, by paying the full fee on time or by filing a request for re-establishment of rights. In response to arguments of the Respondent, the Board had also to consider whether the consequence of its decision would adversely affect one or more parties to the Appeal if the principle of the protection of legitimate expectations applies to this case.
