Federal Circuit Rejects Information Exchange Patent — Abstract Ideas on Generic Computers Remain Ineligible

The U.S. Court of Appeals for the Federal Circuit affirmed on April 7, 2026, that information exchange system patents face insurmountable eligibility barriers under 35 U.S.C. § 101. The case, In re Brian McFadden, involved Application No. 15/891,363, titled “System and Methods for Operating an Information Exchange.” McFadden’s Claim 14 described apparatus and methods for regulating information flows in various forms—social networks, advertising networks, content digests, or any service enabling transmission from producers to consumers. Both the Patent Trial and Appeal Board (PTAB) and the Federal Circuit rejected the claim as directed to unpatentable abstract ideas. The decision is a stark reminder that software and business model patents confront nearly insurmountable § 101 obstacles in contemporary jurisprudence.

The facts and procedural history are straightforward. The USPTO examiner initially rejected Claim 14 on two independent grounds: anticipation under § 102 and ineligibility under § 101. McFadden appealed to the PTAB, which sustained the § 101 rejection and found that the claim “recites a method of organizing human activity” lacking “additional elements or a combination of elements that integrates the recited abstract idea into a practical application.” McFadden appealed to the Federal Circuit.

On Step One of the Alice/Mayo test, the Federal Circuit readily identified the abstract idea. The court characterized the claim’s core function as “generating one distribution of information items, then comparing it to a previous distribution of information items, to determine how information should be presented to a consumer”—quintessential marketing and advertising activity. The specification’s broad definition of “information items” (including “messages,” “audio clips,” “news,” and “advertisements”) reinforced the abstract, not specific, character of the claimed concept. The court stated: “claims describing broad steps of gathering, evaluating, and displaying information, using only standard functions of generic computer components, are considered directed to abstract ideas.”

McFadden’s attempt to characterize the claim as a specialized computer system failed. He argued that the claim described innovations in a specific information-exchange technology, not merely generic computing. The Federal Circuit disagreed, finding that the specification recited only generic computer components and that the claim itself “does not claim any improvements in technology, instead only claiming mathematical operations and determinations implemented via computer.” The court emphasized: “merely ‘reciting use of an abstract mathematical formula on any general purpose computer’ is abstract and does not constitute an improvement to technology.”

The second Alice step—the inventive concept—proved fatal. McFadden argued that the disclosed algorithms provided technological improvement and thus satisfied the inventive concept requirement. The court dismissed this on two grounds. First, the algorithmic arguments were raised only in the reply brief, not in the opening appeal, and thus were waived. Second, even if considered on the merits, the algorithms amounted to nothing more than “computing differences between information distributions at a high level of generality” through “four mathematical formulas for calculating distribution difference.” Generic calculations implemented on standard hardware cannot constitute an inventive concept. The court held: “computer-mediated implementation of routine or conventional activity is not enough to provide an inventive concept.”

McFadden’s means-plus-function fallback also failed. He contended that certain claim elements should be construed as means-plus-function limitations under 35 U.S.C. § 112(f), and that corresponding structure was disclosed in the specification. The court found the disclosed structure to be merely “software running on generic computer elements” with no algorithmic or architectural innovation disclosed.

The decision’s implications for software and business model patents are severe. Patent applicants—especially startups, SaaS companies, FinTech firms, and marketplaces—cannot rely on mere data aggregation, comparison, and decision-making logic to secure patent protection. Claims must demonstrate specific technological improvements, novel hardware configurations, or genuine contributions to computer science itself. The decision suggests that broad claims describing abstract business processes (matching supply and demand, ranking information, regulating peer-to-peer exchange) face categorical rejection under § 101, regardless of economic innovation or business model originality. For companies relying on patent portfolios to protect platform technologies, McFadden signals that prosecution strategy must pivot away from functional claim language toward technical implementation details and computer-architecture specificity. Absent such specificity, patent protection in this domain is likely unattainable under current Federal Circuit doctrine.
