The U.S. Court of Appeals for the Federal Circuit upheld a district court ruling against Fintiv, invalidating their patents for a mobile wallet payment system. The court determined that the 'payment handler terms' in the patent claims were indefinite and constituted 'means-plus-function' terms that lacked adequate corresponding structural disclosure. With the presumption against applying Section 112, paragraph 6 due to the absence of 'means,' the court emphasized the requirement for demonstrable structure linked to the claimed functions to meet patent validity standards.
Unlike in Dyfan, where the expert's testimony that the term 'code' / 'application' connoted software structure to a POSA was unrebutted, here, neither expert testified that the payment-handler terms connoted structure.
