549–550. If the patentee negotiates a contract restricting the purchaser’s right to use or resell the item, it may be able to enforce that restriction as a matter of contract law, but may not do so through a patent infringement lawsuit.

The exhaustion rule marks the point where patent rights yield to the common law principle against restraints on alienation. The Patent Act promotes innovation by allowing inventors to secure the financial rewards for their inventions. Once a patentee sells an item, it has secured that reward, and the patent laws provide no basis for restraining the use and enjoyment of the product. Allowing further restrictions would run afoul of the “common law’s refusal to permit restraints on the alienation of chattels.” Kirtsaeng v. John Wiley & Sons, Inc., 568 U. S. 519, 538. As Lord Coke put it in the 17th century, if an owner restricts the resale or use of an item after selling it, that restriction “is voide, because. . . it is against Trade and Traffique, and bargaining and contracting betweene man and man.” 1 E. Coke, Institutes of the Laws of England §360, p. 223 (1628). Congress enacted and has repeatedly revised the Patent Act against the backdrop of this hostility toward restraints on alienation, which is reflected in the exhaustion doctrine.

This Court accordingly has long held that, even when a patentee sells an item under an express, otherwise lawful restriction, the patentee does not retain patent rights in that product. See, e.g., Quanta Computer, Inc. v. LG Electronics, Inc., 553 U. S. 617. And that well settled line of precedent allows for only one answer in this case: Lexmark cannot bring a patent infringement suit against Impression Products with respect to the Return Program cartridges sold in the United States because, once Lexmark sold those cartridges, it exhausted its right to control them through the patent laws.

(b) The Federal Circuit reached a different result because it started from the premise that the exhaustion doctrine is an interpretation of the patent infringement statute, which prohibits anyone from using or selling a patented article “without authority” from the patentee. According to the Federal Circuit, exhaustion reflects a default rule that selling an item “presumptively grant[s] ‘authority’ for the purchaser to use it and resell it.” 816 F. 3d 721, 742. But if a patentee withholds some authority by expressly limiting the purchaser’s rights, the patentee may enforce that restriction through patent infringement lawsuits. See id., at 741.

The problem with the Federal Circuit’s logic is that the exhaustion doctrine is not a presumption about the authority that comes along with a sale; it is a limit on the scope of the patentee’s rights. The Patent Act gives patentees a limited exclusionary power, and exhaustion extinguishes that power. A purchaser has the right to use, sell,
