  • On September 13, 2004, the United States Court of Appeals for the Federal Circuit issued an en banc ruling in Knorr-Bremse Systeme Fuer Nutzfahrzeuge GMBH v. Dana Corp., holding that there can be no adverse inference drawn from an alleged infringer's failure to obtain or produce an exculpatory opinion of counsel. This decision marks a dramatic change in patent law, expressly overruling twenty years of precedent.
