/>iThe US Court of Appeals for the Federal Circuit affirmed a district court’s ruling that a software term was a “nonce” term that invoked 35 U.S.C. § 112, sixth paragraph (i.e., a means-plus-function claim element). The Court further found that the patent specification did not recite sufficient corresponding structure, rendering the claim element indefinite. Fintiv, Inc. v. PayPal Holdings, Inc., Case No. 23-2312 (Fed. Cir. Apr. 30, 2025) (Prost, Taranto, Stark JJ.)
Fintiv sued PayPal for infringing four patents related to cloud-based transaction systems, also known as “mobile wallet platforms,” “mobile financial services platforms,” or “electronic payment systems.” During claim construction, the district court ruled that the terms “payment handler” and “payment handler service” were indefinite. The court concluded that both terms were means-plus-function limitations governed by § 112, sixth paragraph. Although the claims did not use the word “means,” the district court found that PayPal had demonstrated that the terms were drafted in a format consistent with traditional means-plus-function language, effectively substituting “payment handler” for the word “means.” The court also found that the patent specifications failed to disclose corresponding structure capable of performing the claimed functions. As a result, the court held the claims invalid for indefiniteness and entered final judgment. Fintiv appealed.
Fintiv argued that the district court erred in concluding that the payment handler terms invoked § 112(f) and that the specifications failed to disclose the structure for the claimed functions. The Federal Circuit disagreed.
The Federal Circuit analyzed the “payment-handler” terms, which did not explicitly use the word “means.” Under § 112(f), there is a rebuttable presumption that a claim term does not invoke means-plus-function treatment unless the challenger can show that the term is a nonce term that lacks “sufficiently definite structure” or only recites a function without providing enough structure to perform that function. Fintiv contended that the payment handler terms, both individually and collectively, identified the required structure. However, the Court found that PayPal had successfully rebutted the presumption since the payment handler terms recited functions without reciting sufficient structure to perform those functions. The Court agreed with the district court that the term “handler” did not convey sufficient structure to a person of ordinary skill in the art.
Having determined that the payment handler terms invoked § 112(f), the Federal Circuit sought to identify the corresponding structure described in the specifications for performing the payment handler function but found none. The Court concluded that “without an algorithm to achieve these functionalities – and, more generally, given the specifications’ failure to disclose adequate corresponding structure – we hold the payment-handler terms indefinite.”
