LaFrance on the Supreme Court's Standard for Indefiniteness in Patent Claims: Nautilus, Inc. v. Biosig Instruments, 2014 U.S. LEXIS 3818 (June 2, 2014) (PDF)
Select a format
How indefinite is too indefinite? Because of the limitations of language, innovation does not always lend itself to precise textual description. In Nautilus, Inc. v. Biosig Instruments, Inc., the Federal Circuit held that claims are sufficiently definite so long as they are not "insolubly ambiguous." However, the Supreme Court in Nautilus, Inc. v. Biosig Instruments, 2014 U.S. LEXIS 3818 (June 2, 2014), unanimously rejected this standard.
