Aronson v. Quick Point Pencil Co., 440 U.S. 257 (1979), was a United States Supreme Court case in which the court held that federal patent law does not preempt state contract law so as to preclude enforcement of the contract.

[1] The challenged law required the licensee of a patent-pending invention to pay a royalty to the inventor even if the patent was ultimately denied.

The Supreme Court upheld the law because it did not cause anyone to decline to seek a patent or try to hide their disclosed inventions after the fact.
