Alice Corp. v. CLS Bank International, 573 U.S. 208 (2014), was a 2014 United States Supreme Court decision about patent eligibility of business method patents. The issue in the case was whether certain patent claims for a computer-implemented, electronic escrow service covered abstract ideas, which would make the claims ineligible for patent protection. The patents were held to be invalid, because the claims were drawn to an abstract idea, and implementing those claims on a computer was not enough to transform that abstract idea into patentable subject matter.

DDR Holdings, LLC v. Hotels.com, L.P., 773 F.3d 1245, was the first United States Court of Appeals for the Federal Circuit decision to uphold the validity of computer-implemented patent claims after the Supreme Court's decision in Alice Corp. v. CLS Bank International. Both Alice and DDR Holdings are legal decisions relevant to the debate about whether software and business methods are patentable subject matter under Title 35 of the United States Code §101. The Federal Circuit applied the framework articulated in Alice to uphold the validity of the patents on webpage display technology at issue in DDR Holdings.
