United States patent law governs the issuance, scope, and enforcement of patents in the United States and is grounded in the United States Constitution and statutes enacted by the United States Congress. It operates through administrative institutions such as the United States Patent and Trademark Office and judicial bodies including the Supreme Court of the United States and various federal appellate and United States district courts. The law has evolved through landmark decisions, legislative reforms, and international agreements such as the Patent Cooperation Treaty and the TRIPS Agreement.

History

Early statutory authority derived from the United States Constitution's Article I, Section 8, Clause 8 and initial statutes like the 1790 Patent Act signed under George Washington. Subsequent statutory regimes included the 1793 and 1836 Patent Acts, with administrative reforms influenced by figures such as Thomas Jefferson and controversies like the Seward Purchase era expansion of industry. The 19th century brought industrial disputes exemplified by litigation involving inventors such as Samuel Morse and corporate actors like Eli Whitney. Twentieth-century modernization included the creation of the United States Patent and Trademark Office's modern examination system, and later legislative milestones such as the Leahy-Smith America Invents Act enacted by the 111th United States Congress. Judicial developments were shaped by decisions from the Supreme Court of the United States and the United States Court of Appeals for the Federal Circuit, including cases involving parties like KSR International Co., Teleflex Inc., Alice Corporation Pty. Ltd., and actors in biotechnology disputes involving Myriad Genetics and Association for Molecular Pathology.

Inventive subject matter must satisfy statutory sections rooted in the United States Code. Eligibility requires compliance with statutory categories established in precedents including Diamond v. Chakrabarty and limits articulated by Alice Corp. v. CLS Bank International and Mayo Collaborative Services v. Prometheus Laboratories, Inc.. Novelty and nonobviousness standards derive from statutes and cases such as Graham v. John Deere Co., with obviousness principles refined in KSR International Co. v. Teleflex Inc.. Written description, enablement, and definiteness obligations were clarified in cases like Ariad Pharmaceuticals, Inc. v. Eli Lilly and Co. and Nautilus, Inc. v. Biosig Instruments, Inc.. Statutory bars and priority derive from reforms in the Leahy-Smith America Invents Act and interplay with treaties such as the Patent Cooperation Treaty. Patentable subject matter controversies have involved biotechnology firms like Myriad Genetics and software companies such as Microsoft Corporation.

Applications are filed with the United States Patent and Trademark Office and may begin via provisional filings or international routes under the Patent Cooperation Treaty involving institutions like the World Intellectual Property Organization. Examiners apply statutes, rules, and examination guidelines influenced by agencies such as the United States Department of Commerce and precedents from the United States Court of Appeals for the Federal Circuit and the Supreme Court of the United States. Prosecution processes include claim drafting, office actions, appeals to the Patent Trial and Appeal Board, and potential appeals to the United States Court of Appeals for the Federal Circuit. Patent applicants and prosecutors include law firms, corporations like IBM, universities such as Stanford University and Massachusetts Institute of Technology, and independent inventors akin to Thomas Edison in historical disputes. Fee structures and practice rules reflect administrative law principles and statutes enacted by the United States Congress.

Ownership rules trace to statutes, contract law, and precedents involving corporate transactions by entities like General Electric and mergers overseen by regulators such as the Federal Trade Commission. Assignment and recordation occur at the United States Patent and Trademark Office; transfers among parties including Google LLC, Apple Inc., and spin-offs from institutions like Harvard University have shaped practice. Employer–employee allocation of rights often stems from agreements influenced by cases involving inventors at firms such as Bell Telephone Company and research institutions including National Institutes of Health. Licensing markets involve transactions among patent holders, aggregators such as Intellectual Ventures, and litigation-finance actors exemplified by parties in eBay Inc. v. MercExchange, L.L.C..

Enforcement proceeds in United States district courts and specialized tribunals like the Patent Trial and Appeal Board. Landmark enforcement decisions from the Supreme Court of the United States—including eBay Inc. v. MercExchange, L.L.C. and Markman v. Westview Instruments, Inc.—have influenced injunctive relief and claim construction doctrines. The United States Court of Appeals for the Federal Circuit has shaped remedies and standards in disputes involving firms such as Qualcomm, Intel Corporation, Samsung Electronics, and Apple Inc.. International disputes invoke treaties like the North American Free Trade Agreement in cross-border cases and are affected by decisions in trade bodies such as the United States International Trade Commission.

Remedies include injunctions, damages, and equitable relief as refined by eBay Inc. v. MercExchange, L.L.C. and damages frameworks shaped by cases like Halo Electronics, Inc. v. Pulse Electronics, Inc. and Lucent Technologies, Inc. v. Gateway, Inc.. Post-grant procedures established by the Leahy-Smith America Invents Act created administrative reviews such as inter partes review before the Patent Trial and Appeal Board, with substantial jurisprudence from the United States Court of Appeals for the Federal Circuit and commentary from organizations like the American Intellectual Property Law Association. Settlement dynamics involve parties including Cisco Systems, Inc., Toyota Motor Corporation, and generic manufacturers addressed by cases in pharmaceutical domains such as disputes involving Pfizer and Novartis AG.
