WASHINGTON, DC – The United States Federal Circuit Court of Appeals should act more like a teacher to the Supreme Court and do a better job explaining its policy reasoning when it makes decisions on innovation-related cases, a top patent law academic said late Tuesday. If the Federal Circuit was clearer in how it landed at certain conclusions in patent disputes it might result in the Supreme Court opting to get involved in fewer patent cases, said Rochelle Dreyfuss, a professor at New York University School of Law.
