Lear, Inc. v. Adkins, 395 U.S. 653 (1969), is a decision of the U.S. Supreme Court overturning the doctrine of licensee estoppel and holding that public interest considerations require that licensees be free to challenge the validity of possibly spurious patents under which they are licensed. This entailed the overruling of Automatic Radio Mfg. Co. v. Hazeltine Research, Inc. and prior cases that it had reaffirmed.
