The Forgotten Half of the Patent Clause
II · Doctrinal Foundation
Eight Decades of Settled Doctrine
The Supreme Court Has Already Spoken
Across two centuries the Court has repeatedly affirmed that patent expiration is the payoff of the constitutional bargain, not an afterthought — and that reservations of patent-like protection after expiration are unlawful whatever the device employed.
Historical Doctrine — Patent Clause Settled Long Ago
1945
Scott Paper v. Marcalus
"Any attempted reservation or continuation … after the patent expires, whatever the legal device employed, runs counter to the policy and purpose of the patent laws." — Chief Justice Stone.
1989
Bonito Boats v. Thunder Craft
The federal patent system creates "a federal right to copy and to use" once a patent has expired. Graham v. John Deere (1966) grounds the same point in Jefferson's original understanding of the Clause.
2015
Kimble v. Marvel
"When the patent expires, the patentee's prerogatives expire too, and the right to make or use the article, free from all restriction, passes to the public."
Modern Landscape — Why 2026 Is the Right Moment
2022
West Virginia v. EPA
Major Questions Doctrine. Agencies exercising powers of "vast economic and political significance" must point to clear congressional authorization. Congress never authorized EPA, NHTSA, or DOE to nullify the Patent Clause.
2024
Loper Bright v. Raimondo
Ended Chevron deference. Courts no longer defer to agency interpretations when reviewing whether a regulation exceeds the statute that authorizes it.
2024
Sheetz v. El Dorado County
Expanded regulatory takings protections. Broadened when government action constitutes a compensable taking — directly applicable to expired-patent designs.
2021
Cedar Point Nursery v. Hassid
"Government-authorized invasions of property … are physical takings requiring just compensation." — Chief Justice Roberts. Reservation of the expired-patent public domain to incumbents is such an invasion.
2023
Tyler v. Hennepin County
"The taxpayer must render unto Caesar what is Caesar's, but no more." — Chief Justice Roberts. Extension of market power past the 20-year patent term is retention of surplus that belongs to the public.
Restoring the Forgotten Half of the Patent Clause
The Remedy
Grandfathering, Not Deregulation
A newly-remanufactured expired-patent design would meet the safety and emissions rules in effect when the original patent issued — the same treatment every existing machine of that vintage already receives on American roads today.
The Mechanism
Independent Engineering Certification
A qualified third party verifies that every component within the scope of federal energy and safety regulation draws from patent-expired prior art of the selected vintage year, with no new patents read into that scope.

III · A Choice, Not a Necessity
Ninety nations allow what the United States forbids. Two structural reasons explain why the question has not been asked here for fifty-five years.
Regulatory Capture
Manufacturers and Advocates, Same Direction
Bruce Yandle's 1983 "Bootleggers and Baptists" framework describes the pattern. Incumbent manufacturers benefit from permanent monopolies on expired-patent designs; environmental and safety advocates supply moral cover for the rules that produce that monopoly. Neither side has an incentive to raise the constitutional question.
Manufacturers fund lobbyists. Lobbyists fund legislators. Legislators staff agencies. Agencies hire from industry. Courts defer. Every actor in the loop profits — except the public holding the expired patents.
The Doctrinal Pigeonhole
Where Cross-Cutting Questions Fall
Patent scholarship has organized itself around creation — prosecution, claim construction, validity, enforcement. Expiration is treated as the closing bracket of that inquiry, not the opening bracket of a second one. Thousands of articles on how patent rights come into being; very few on what is supposed to come into being when they end.
The question raised here does not fit the existing pigeonhole. That structural fact — not any failing of inquiry — is why it has lived for fifty-five years in the space between fields.
The Domestic Evidence
95.5%
Bicycles are more affordable since 1910. Zero federal safety regulation. Child cyclist deaths fell 88% in 48 years — outperforming the regulated automobile's 62%. Free market delivered affordability, innovation, and safety simultaneously.
90.5%
When calculator patents expired and no agency blocked competition, the HP 12C dropped from $150 in 1981 ($530 today) to $49.99. HP still makes it. That is the Founders' promise, delivered.

IV · The Paths and the Ask
What You Are Being Asked to Do
Three Paths, Three Levels
Three Independent Legal Paths
01
Patent Clause Violation
Article I, §8, cl. 8
"Limited Times" was breached the moment regulators began blocking remanufacturing of patent-expired designs. Settled doctrine — Scott Paper, Bonito Boats, Kimble.
02
Takings Clause
Fifth Amendment
The public's reversionary interest in expired patents is property. James v. Campbell (1882) establishes that patents are property within the Fifth Amendment; Horne v. USDA (2015) confirms that the per se takings rule is not limited to real property. A permanent regulatory cancellation of that interest is a taking.
03
Major Questions Doctrine
West Virginia v. EPA (2022)
None of the relevant statutes — Clean Air Act, Energy Policy and Conservation Act, National Traffic and Motor Vehicle Safety Act — authorizes an agency to nullify the Patent Clause's guarantee.
A litigant who loses on one prong may still win on the others.
Why This Campaign Needs the Public-Domain Community
Seven plaintiff-candidate fronts are already engaged — county sheriffs, governors and state attorneys general, tribal nations, owner-operator truckers, farm associations, healthy-lighting advocates, and a dedicated mailing toolkit at marti124.github.io/Patent_Letters/. These constituencies testify to injury. They do not construct doctrine. That work — which briefs, amicus filings, research streams, and scholarly validation ultimately rest upon — is what only your community produces.
The Ask, in Three Levels
01
Read and React
A brief email telling me whether the argument strikes you as coherent, incomplete, or mistaken. Dissent is as useful as agreement.
02
Place It Within Your Agenda
If your center, firm, or organization has room for a research stream, an amicus brief, a panel, or a blog post on this question on its own terms, consider doing so.
03
Connect It
Introduce the argument to scholars, litigators, journalists, or funders whose work would be improved by knowing about it.
