A new EPO Boards of Appeal decision T 84/19 deals with an interesting question relating to appeal fees. The decision holds that an opponent who is a natural person or otherwise entitled to benefit from the reduced appeal fee does not have to pay the full appeal fee, even if there is a secret sponsor (akin to the ‘real party in interest’ in post-grant proceedings in other jurisdictions). This holds as long as the opposition does not constitute a circumvention of the law regarding the entitlement to pay a reduced appeal fee.
By way of background for the readers familiar with or otherwise interested in USPTO post-grant proceedings: According to decisions G 3/97, G 4/97, it is not required that the ‘real party in interest’ be named in EPO opposition proceedings. Thus, the situation may (and does) occur in which an opponent as party to the EPO proceedings may be different from the person interested in the revocation or amendment of the patent.
