35 U.S.C. Patent Statute
Note: 35 U.S.C. is not a Supreme Court case — it is the federal Patent Act of 1952, a statute enacted by Congress that established the comprehensive framework governing what inventions may be patented, what rights patent holders possess, and how patent disputes are resolved in the United States.

Because 35 U.S.C. is a statute rather than a judicial opinion, there is no 'holding' in the traditional sense. Instead, the Act established several foundational legal principles that continue to govern American patent law.
First, the statute defined patentable subject matter broadly: anyone who 'invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof' may obtain a patent (§ 101). It then set out three core requirements for patentability: novelty (§ 102), meaning the invention must be genuinely new; non-obviousness (§ 103), meaning it must not be an obvious variation of existing knowledge to a person of ordinary skill in the relevant field; and adequate written description and enablement (§ 112), meaning the patent application must describe the invention clearly enough for others to understand and reproduce it.
Second, the Act codified the rights of a patent holder, granting the exclusive right to exclude others from making, using, or selling the patented invention for a limited term (now 20 years from the filing date). It also spelled out remedies for infringement, including injunctions, damages, and in some cases enhanced damages for willful infringement (§§ 281–285).
Third, the statute created orderly procedures for patent prosecution (the process of applying for and obtaining a patent from the Patent Office) and for resolving disputes, including provisions for declaratory judgment actions and defenses to infringement claims such as invalidity and inequitable conduct.
The non-obviousness requirement of § 103 was one of the Act's most important innovations. Before 1952, courts had applied a vague and inconsistent 'flash of creative genius' standard. Section 103 replaced that with a more objective test, asking whether the differences between the claimed invention and the prior art would have been obvious to a skilled practitioner at the time the invention was made. This provision has been interpreted and refined by the Supreme Court in numerous subsequent cases and remains central to patent litigation today.
Concurring Opinions
Because 35 U.S.C. is a statute enacted by Congress and not a Supreme Court opinion, there are no concurring or dissenting judicial opinions. However, commentators and courts have debated the proper interpretation of many of its provisions — particularly § 101 (patent-eligible subject matter), § 103 (non-obviousness), and § 112 (written description and enablement) — in landmark Supreme Court cases spanning from Graham v. John Deere Co. (1966) to Alice Corp. v. CLS Bank International (2014).
Background & Facts
Important clarification: 35 U.S.C. (Title 35 of the United States Code) is a federal statute, not a decision of the United States Supreme Court. It is the Patent Act of 1952, signed into law on July 19, 1952. What follows is an accurate description of this landmark legislation adapted to the available format.
Before 1952, American patent law was a patchwork of statutes dating back to 1790, supplemented by decades of often-conflicting judicial interpretations. There was no single, coherent statutory code that laid out the requirements for obtaining a patent, the scope of a patent holder's rights, or the procedures for challenging or enforcing patents. Courts filled the gaps with common-law doctrines, but the result was confusion and inconsistency.
Two key figures — patent examiner P.J. Federico of the U.S. Patent Office and attorney Giles S. Rich (who later became a federal judge) — played central roles in drafting the new statute. Working under the auspices of a congressional subcommittee, they set out to codify, clarify, and modernize the entire body of U.S. patent law into a single, logically organized title of the United States Code.
The bill passed both chambers of Congress with broad bipartisan support and was signed into law by President Harry S. Truman. It became effective on January 1, 1953. Title 35 has been amended many times since — most significantly by the America Invents Act of 2011 — but its basic structure and many of its core provisions remain intact.
The statute is divided into four parts covering the United States Patent and Trademark Office and its officers, patentability and the granting of patents, patents and the protection of patent rights, and the Patent Trial and Appeal Board and related proceedings. It is the single most important piece of legislation in American patent law and is cited in virtually every patent dispute that reaches any federal court, including the Supreme Court.
The Arguments
Congress sought to consolidate, clarify, and modernize the scattered body of American patent law into a single, coherent statutory framework. The goal was to make patent law more predictable for inventors, businesses, and the courts.
- Prior patent statutes were fragmented across multiple enactments dating to 1790 and were difficult to reconcile with one another.
- Courts had developed conflicting common-law doctrines to fill gaps in the existing statutes, creating uncertainty about what was patentable and what rights a patent conferred.
- A modern industrial economy required a clear, uniform national standard for patent eligibility, prosecution, and enforcement.
