High Court Nixes ‘Amenable to Construction,' ‘Insolubly Ambiguous' Indefiniteness Rules

On June 2, the U.S. Supreme Court issued a decision in Nautilus, Inc. v. Biosig Instruments, Inc., determining “the phrases ‘amenable to construction’ and ‘insolubly ambiguous’ for purposes of identifying an indefinite patent claim are ’lack precision’.” Finnegan partner James R. Barney said, “All patents in all areas of technology could be susceptible to indefiniteness challenges depending on how the Federal Circuit applies the new Nautilus test.”
