Alice Corp. v. CLS Bank: The Two-Step Test That Reshaped Software Patents

Alice Corp. Pty. Ltd. v. CLS Bank International, 573 U.S. 208 (2014), Docket No. 13-298, decided June 19, 2014, is the most consequential patent-eligibility decision of the modern era. Writing for a unanimous Court, Justice Thomas held that Alice’s claims to a computerized scheme for mitigating “settlement risk” — the risk that one party to a financial exchange will not pay — were directed to an abstract idea, and that implementing that idea on a generic computer did not supply the “inventive concept” needed to make it patent-eligible under 35 U.S.C. § 101. By extending the framework first articulated in Mayo to abstract ideas, Alice gave courts a single, two-step test that would invalidate thousands of software and business-method claims in the decade that followed.

At a glance

• Case: Alice Corp. Pty. Ltd. v. CLS Bank International, 573 U.S. 208 (2014), Docket No. 13-298
• Court: Supreme Court of the United States, on certiorari to the en banc Federal Circuit
• Decided: June 19, 2014; unanimous
• Opinion: Justice Thomas, for the Court; Justice Sotomayor concurring (joined by Ginsburg and Breyer)
• Subject matter: Computer-implemented methods, systems, and media for using a third-party intermediary to mitigate settlement risk
• Holding: Claims directed to an abstract idea are not made patent-eligible merely by reciting their implementation on a generic computer

The claims and the fractured court below

Alice Corporation held patents on a scheme for managing settlement risk in financial transactions. The basic idea was to use a neutral intermediary that maintained “shadow” records of each party’s account, updated those records as obligations arose, and permitted only those transactions for which both parties had sufficient resources — in effect, a computerized form of escrow that ensured each side could perform before the exchange settled. The patents claimed this concept in three forms: as a method, as a computer system configured to carry out the method, and as a computer-readable medium containing the program code.

CLS Bank, which operates a global settlement system, sought a declaratory judgment that the claims were invalid; Alice counterclaimed for infringement. The case produced an unusually divided en banc Federal Circuit, which fragmented across multiple opinions and could not agree on a rationale, even as a majority concluded the method and media claims were ineligible. That doctrinal disarray made the case an ideal vehicle for the Supreme Court to supply a unifying standard.

Applying the Mayo framework to abstract ideas

The Court’s analysis is the clearest statement of the two-step test. At step one, the Court asked whether the claims are directed to a patent-ineligible concept. It concluded they were: the concept of intermediated settlement — using a third party to reduce the risk that one side fails to perform — is “a fundamental economic practice long prevalent in our system of commerce,” squarely within the abstract-idea category recognized in Bilski. The Court declined to draw a precise boundary for what counts as an “abstract idea,” finding it enough that intermediated settlement was as much a building block of the modern economy as the hedging at issue in Bilski.

At step two, the Court searched the claim elements, individually and as an ordered combination, for an “inventive concept” sufficient to transform the abstract idea into a patent-eligible application. Here the claims failed decisively. The function of the computer in Alice’s claims was wholly generic — creating and maintaining records, adjusting account balances, issuing automated instructions. Each step “requires a generic computer to perform generic computer functions,” and taken together the claims did no more than instruct a practitioner to implement the abstract idea of intermediated settlement on an ordinary computer. That, the Court held, is not enough: “the mere recitation of a generic computer cannot transform a patent-ineligible abstract idea into a patent-eligible invention.”

System and media claims rise and fall with the method

A critical feature of Alice is its treatment of claim form. Alice had argued that even if the method claims were ineligible, its system claims — reciting specific hardware like a “data processing system,” a “communications controller,” and a “data storage unit” — and its media claims should survive. The Court rejected the distinction. Because the recited hardware was purely generic, the system and media claims added nothing of substance to the method claims; they were “no different from the method claims in substance.” Allowing a claim to escape § 101 simply by recasting an abstract method in the language of a system or a storage medium would, the Court warned, make the eligibility doctrine “a dead letter,” depending on “the draftsman’s art” rather than the substance of the invention.

This holding is one of Alice’s most practically important. It foreclosed the common patent-drafting strategy of recharacterizing the same ineligible concept across multiple claim formats to manufacture eligibility, and it required courts to look past the form of a claim to what it actually covers.

Open questions

Alice supplied a framework but not a definition. The Court expressly declined to delimit the “precise contours of the abstract ideas category,” and that omission has driven a decade of litigation. How does a court reliably distinguish an abstract idea from a concrete technological improvement at step one? When does a combination of conventional components cross from generic implementation into a genuine inventive concept at step two? And how should the test treat claims that genuinely improve the functioning of a computer itself, as opposed to claims that merely use a computer as a tool? The Court left those lines for development in the lower courts, and the resulting uncertainty has been the defining feature of post-Alice patent practice.

Implications

• Generic computer implementation is not enough. Reciting that an abstract idea is carried out “on a computer,” “over the internet,” or by a generic processor will not, without more, confer eligibility.
• Claim form does not save substance. System and computer-readable-medium claims fall with their corresponding method claims when the recited hardware is generic; drafting around § 101 by changing claim category does not work.
• Look for a technological improvement. The strongest eligibility arguments after Alice describe an improvement to computer functionality or a specific technical solution, not merely the automation of a known practice.
• A unified test across exceptions. Alice completed the framework begun in Mayo, applying the same two-step inquiry to abstract ideas, laws of nature, and natural phenomena alike.

Frequently asked questions

What is the Alice/Mayo two-step test? First, determine whether the claim is directed to a patent-ineligible concept (an abstract idea, law of nature, or natural phenomenon). Second, if so, determine whether the claim’s additional elements, individually and in combination, add an “inventive concept” that transforms it into a patent-eligible application.

Why did Alice’s claims fail? Intermediated settlement is an abstract idea — a fundamental economic practice — and the claims merely required a generic computer to perform generic functions to carry it out, adding no inventive concept.

Did Alice ban software patents? No. The Court did not hold that software or computer-implemented inventions are categorically ineligible. It held that claims must do more than implement an abstract idea on a generic computer; claims that improve the functioning of a computer or solve a specific technical problem can remain eligible.
