Alice Corp. v. CLS Bank Int'l
The Court ruled that a company's patents on a computer-run system for settling financial trades through a middleman are not valid, because the underlying idea — using a third party to make sure both sides of a trade actually pay up — is just an abstract, centuries-old business concept.
Simply running that old idea on an ordinary, generic computer does not turn it into a patentable invention. The decision reinforces a two-step test for weeding out patents that lock up basic ideas rather than genuine technological advances, with broad consequences for software and financial-technology patents nationwide.
“We hold that the claims at issue are drawn to the abstract idea of intermediated settlement, and that merely requiring generic computer implementation fails to transform that abstract idea into a patent-eligible invention.”
The Court's core holding on why the computerized settlement patents are invalid.
How it got here: A federal trial court ruled the patents invalid as an abstract idea; a Federal Circuit panel reversed, but the full Federal Circuit sitting en banc restored the trial court's ruling, and Alice asked the Supreme Court to review it.
The Case in Depth
What happened
Alice Corporation held patents describing a computerized method in which a neutral third party keeps 'shadow' account records to make sure both sides of a financial trade have enough money before the trade goes through, reducing the risk that one side pays and the other doesn't. CLS Bank, which runs a real-world currency-trading network, sued for a court declaration that Alice's patents were invalid, and Alice countersued for patent infringement.
The question before the Court
Can a company get a patent on a computerized method for reducing financial settlement risk, just by having a generic computer run an old business idea?
Why it matters
Businesses and software developers can no longer patent everyday business practices merely by adding 'on a computer' to the claim. The ruling gave courts a clearer tool to throw out weak software patents, which affected thousands of existing patents and shaped how companies draft and defend technology patents afterward.
What changes now
This is a final merits decision affirming the Federal Circuit's ruling that Alice's patents are invalid, so the patents cannot be enforced against CLS Bank or anyone else. The decision immediately became the controlling test for challenging similarly framed software and business-method patents in ongoing and future litigation, prompting courts and the Patent Office to reassess many pending computer-related patents under this two-step approach.
What this does not decide
The Court expressly declined to define the precise boundaries of what counts as an 'abstract idea,' saying it was enough that intermediated settlement was no different from the risk-hedging idea already found abstract in Bilski. It also did not hold that all software or computer-implemented inventions are unpatentable — only that generic computer implementation of an abstract idea is not enough.
Concurrences and dissents
Concurrence — Justice Sotomayor
Justice Sotomayor, joined by Justices Ginsburg and Breyer, joined the Court's opinion in full but wrote separately to restate her long-held view that any patent claim that merely describes a way of doing business does not even qualify as a 'process' eligible for patent protection under the statute, a broader position than the majority adopted.
How the Court got there
The legal reasoning, step by step
- The Court applied the two-step framework from Mayo Collaborative Services v. Prometheus Laboratories: first ask whether the patent claims are aimed at a law of nature, natural phenomenon, or abstract idea, all of which cannot be patented on their own because they are basic tools of human thought.
- If so, the Court asks whether the rest of the claim adds an 'inventive concept' — something significantly more than the abstract idea itself — that is enough to ensure the patent isn't just a way to lock up the idea for everyone else.
- The Court found that using a neutral middleman to guarantee both sides of a trade pay up is the same kind of 'fundamental economic practice' as the risk-hedging idea the Court had already called abstract in Bilski v. Kappos, so intermediated settlement itself is an abstract idea.
- Turning to step two, the Court examined the computer elements of the claims — creating records, adjusting balances, and issuing instructions — and found each function was purely conventional, the kind of basic recordkeeping any general-purpose computer already does.
- Because the claims did not improve how a computer works or solve any other technical problem, adding a generic computer to the abstract idea did not supply the missing inventive concept, whether the claims were framed as a method, a computer system, or a computer-readable medium.
Doctrinal impact
Cases affected by this decision
Reaffirms Mayo Collaborative Services v. Prometheus Laboratories, Inc. (566 U.S. ----)
The Court reused Mayo's two-step framework for identifying unpatentable abstract ideas and applied it to computer patents.
Reaffirms Bilski v. Kappos (561 U.S. 593)
The Court treated Bilski's finding that risk-hedging is an abstract idea as controlling for the similar concept of intermediated settlement.
Distinguishes Diamond v. Diehr (450 U.S. 175)
The Court said Diehr's rubber-curing patent was valid because it solved a real technical problem, unlike Alice's claims.
