Motion Picture Patents Co. v. Universal Film Manufacturing Co.
The Supreme Court ruled that a patent holder cannot use a notice attached to a patented projector to control what unpatented films or supplies the buyer must use with it, or to impose new fees after the sale. Once a patented machine is sold, the patent owner's control over it under the patent laws ends.
The decision overturned the Court's own earlier ruling in Henry v. Dick Co. and rejected a widely used business practice of tying patented machines to required unpatented supplies, a practice the Court found let patent holders squeeze extra profits far beyond what their invention actually covered.
How it got here: A federal trial court ruled the notice-based restriction invalid and dismissed the infringement suit; the Second Circuit affirmed; the patent holder sought Supreme Court review.
The Case in Depth
What happened
A movie equipment company held a patent on part of a film-projector mechanism and licensed a manufacturer to sell projectors bearing a notice restricting their use to films containing another (soon-to-expire) patent, plus other future terms the company might set. A theater bought one of these projectors, and after the film patent expired, it used films from an outside film company. The equipment company sued for patent infringement.
The question before the Court
Could a company that patented part of a movie projector use a notice on the machine to force theaters to only use the company's own films, even after the machine was sold and paid for?
Why it matters
Businesses that made and sold patented equipment could no longer use notice-based conditions to force customers to keep buying separate unpatented supplies, films, or replacement parts from them alone. This curbed a common tactic for extracting ongoing profits from equipment sales and gave purchasers more freedom to use patented machines however they saw fit once bought.
What changes now
The ruling is a final merits decision resolving the infringement claim in the theater's favor. It also formally overruled Henry v. Dick Co., eliminating the legal basis lower courts had relied on to enforce similar notice-based restrictions nationwide, meaning patent holders using comparable tie-in notices could no longer enforce them through infringement suits going forward.
What this does not decide
The Court expressly left aside the effect of the newly enacted Clayton Act on such arrangements, and did not address what would happen under a private contract (rather than a patent-law notice) restricting use of unpatented supplies, or under a combination of patents raising separate antitrust-style concerns.
Concurrences and dissents
Concurrence — Justice McReynolds
Justice McReynolds agreed with the outcome affirming the lower courts but did not join the majority's reasoning. The opinion provides no further explanation of what he would have decided differently.
Dissent — Justice Holmes
“I cannot understand why he may not keep it out of use unless the licensee, or, for the matter of that, the buyer, will use some unpatented thing in connection with it.”Holmes argues a patentee's right to withhold a device entirely implies a right to condition its use on buying other goods.
Justice Holmes argued that because a patentee can withhold a patented device from public use entirely, it follows that the patentee may also condition any use of the device on the buyer purchasing the patentee's unpatented supplies, such as films or tea. He viewed this as an ordinary incident of ownership rather than an improper extension of the patent monopoly, and he stressed that businesses had relied for years on the older rule from Henry v. Dick Co., which he would have kept in place.
How the Court got there
The legal reasoning, step by step
- The Court read the patent statute's grant of an 'exclusive right to use' an invention narrowly, holding that a patent covers only the specific mechanism described in its claims, not the unpatented materials or supplies used with that mechanism.
- Because the patent law traces its purpose to promoting public knowledge rather than maximizing private profit, the Court reasoned that letting a patentee control unpatented supplies through a mere attached notice would stretch the patent monopoly beyond what Congress authorized.
- The Court distinguished the rights a patentee holds under the patent laws (enforceable against the whole world through an infringement suit) from rights created only by private contract (enforceable, if at all, under ordinary contract law, not patent law).
- Applying its earlier ruling in Bauer v. O'Donnell — which held that a patentee's right to control resale price is used up after the first sale — the Court found the same exhaustion logic applies to use restrictions: once the machine is sold, the patent monopoly over it is spent.
- Because the notice's restrictions to specific films and to future undefined terms had nothing to do with the patented mechanism itself, the Court concluded such restrictions could not be enforced as patent infringement, and the conflicting rule from Henry v. Dick Co. could not stand.
Doctrinal impact
Cases affected by this decision
Overrules Henry v. Dick Co. (224 U.S. 1)
The Court struck down the earlier rule allowing patentees to restrict use of sold machines to specific unpatented supplies.
Reaffirms Bauer v. O'Donnell (229 U.S. 1)
The Court relied on this case's rule that a patentee's control over an item ends after its first authorized sale.
