Dr. Miles Medical Co. v. John D. Park & Sons Co.
The Supreme Court ruled that a medicine manufacturer could not use a web of contracts with wholesalers and retailers to fix the minimum prices at which its products would be resold all the way down the chain to consumers, once it had sold the goods and given up title to them.
The decision treats price-fixing agreements among dealers as illegal restraints of trade no matter who orchestrates them, meaning a manufacturer cannot achieve through identical contracts with hundreds of dealers what those dealers could not lawfully agree to do among themselves.
“The complainant having sold its product at prices satisfactory to itself, the public is entitled to whatever advantage may be derived from competition in the subsequent traffic.”
The Court's core reasoning that a manufacturer loses control over resale prices once it has sold its goods.
How it got here: The manufacturer sued in federal court to stop the discount wholesaler from inducing breaches of its pricing contracts; the lower courts ruled against the manufacturer, which then sought Supreme Court review.
The Case in Depth
What happened
A manufacturer of secret-formula proprietary medicines built a nationwide system of contracts with over 400 wholesalers and 25,000 retailers requiring them to sell its remedies at fixed minimum prices. A wholesale drug company refused to sign the contracts and instead obtained the medicines at discounted "cut prices" by inducing other dealers who had signed to break their price commitments.
The question before the Court
Could a medicine maker force every wholesaler and retailer who bought its products to resell them at prices the manufacturer had fixed in advance?
Why it matters
Manufacturers of ordinary consumer goods lost a tool for controlling how cheaply their products could be resold once sold, meaning retailers and wholesalers regained freedom to discount and compete on price. Businesses that wanted to keep prices uniform had to find other means, since contracts fixing resale prices after a sale could not be enforced through the courts.
What changes now
The Sixth Circuit's judgment against the manufacturer stands, meaning the discount wholesaler could continue obtaining and reselling the medicines at cut prices without facing liability for inducing breach of the price-fixing contracts. The ruling set the framework that manufacturers' resale price agreements with dealers were treated as unlawful restraints of trade in later cases applying this decision.
What this does not decide
The Court did not decide what protection, if any, a manufacturer would have if it structured retail dealers as true legal agents who never took title to the goods, and it expressly left the scope of patent-holders' pricing rights undecided since no patent was involved here.
Concurrences and dissents
Dissent — Justice Holmes
“I think that, at least, it is safe to say that the most enlightened judicial policy is to let people manage their own business in their own way, unless the ground for interference is very clear.”Holmes's argument that courts should be cautious about second-guessing private pricing arrangements.
Justice Holmes argued that a manufacturer selling directly to retailers should be free to contract with them not to resell below a certain price, just as an artist could restrict resale of a single painting. He saw no meaningful difference between fixing prices on one item and doing so for many identical items sold to many dealers, and he doubted the value courts placed on price competition, trusting the manufacturer to set reasonable prices. He would have found the discount dealer's inducement of contract breaches unlawful and ruled for the manufacturer.
How the Court got there
The legal reasoning, step by step
- The Court first examined whether the 'consignment contract' with wholesalers was a true agency arrangement (where the manufacturer keeps ownership and the wholesaler merely sells on its behalf) or a disguised sale. It found the contract's actual terms, including provisions letting wholesalers sell to each other and account only for net proceeds, meant many dealers held real ownership rather than acting purely as agents.
- Because those dealers owned the goods outright once purchased, the manufacturer could not rely on the legal principle protecting agency relationships (that a wrongdoer who induces an agent to betray a principal's trust can be stopped); the case instead had to be judged as an attempt to control prices charged by independent owners of goods.
- The Court then asked whether a manufacturer's ownership of a secret formula gave it any special right to control resale prices beyond an ordinary manufacturer's rights. It concluded that a trade secret only protects against theft or breach of confidence regarding the process itself, and does not extend to controlling the price of the finished product once sold.
- Turning to the general question of a manufacturer's power to fix resale prices, the Court applied the common-law rule against restraints on alienation — the principle that once someone owns property outright, restricting their ability to resell or set its price is generally void as against public policy, because free trade in goods that have changed hands benefits the public.
- The Court reasoned that if a group of independent dealers could not lawfully agree among themselves to fix resale prices and stifle competition, a manufacturer could not achieve the identical anticompetitive result simply by inserting the same restriction into identical contracts with each dealer individually.
- Applying these principles, the Court held that the manufacturer's interlocking system of price-fixing contracts restrained trade unlawfully, so no legal wrong had been done to the manufacturer when the discount wholesaler induced dealers to sell below the fixed prices.

The Court said patent licensing price restrictions don't apply here because the manufacturer held no patent on its medicines.
