B.B. Chemical Co. v. Ellis, 314 U.S. 495 (1942), is a United States Supreme Court decision involving the patent misuse doctrine and the extent of remedies a court should award after finding a misuse that the patentee alleges it has now discontinued. The Court ruled that to be able to enforce the patent against infringement the patentee must show that it has fully abandoned its unlawful practice and that the consequences of that practice have been fully dissipated. This was a companion case to Morton Salt Co. v. G.S. Suppiger Co. decided on the same day.
