How did the 1952 Patent Act affect the Old Combination principle?
The 1952 Patent Act had a significant impact on the Old Combination principle, effectively invalidating it. According to MPEP 2173.05(j):
“A majority opinion of the Board of Appeals held that Congress removed the underlying rationale of Lincoln Engineering in the 1952 Patent Act, and thereby effectively legislated that decision out of existence. Ex parte Barber, 187 USPQ 244 (Bd. App. 1974).”
This means that the 1952 Patent Act changed the legal landscape in a way that no longer supported the Old Combination principle. As a result, patent examiners and courts now focus on the statutory requirements, particularly those in 35 U.S.C. 112(b), rather than applying the Old Combination doctrine.
