Supreme Court Mandates More Patent Claim Clarity

By Darren Donnelly
July 02, 2014

In Nautilus, Inc. v. Biosig Instruments, Inc., No. 13-369, 572 U.S. __ (2014), a unanimous Supreme Court held that the test for patent claim definiteness in 35 U.S.C. '112, '2 (2006) “require[s] that a patent's claims, viewed in light of the specification and prosecution history, inform those skilled in the art about the scope of the invention with reasonable certainty.” Vacating a Federal Circuit opinion applying that court's test, the Supreme Court concluded that such test “lack[ed] the precision '112, '2 demands,” and could “breed lower court confusion.”

'Definiteness' Requirement For Patent Claims

The relevant text of 35 U.S.C. 112, '2 requires patent claims “particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.” This provision had come to be known as the “definiteness” requirement for patent claims and those failing to meet the requirement are invalid as “indefinite.” 35 U.S.C. '282. The Federal Circuit had evolved a strict standard under which a claim was invalid as indefinite only if the claim was “not amenable to construction” or, if construed, remained “insolubly ambiguous.” Perhaps because the Federal Circuit's standard focused on construction of the claim term at issue, as a practical matter, district courts often substantively applied the definiteness standard in connection with claim construction proceedings, granting summary judgment of indefiniteness, if the claim failed to meet the standard during claim construction.

The Stranger to the Deed Rule Image

In 1987, a unanimous Court of Appeals reaffirmed the vitality of the "stranger to the deed" rule, which holds that if a grantor executes a deed to a grantee purporting to create an easement in a third party, the easement is invalid. Daniello v. Wagner, decided by the Second Department on November 29th, makes it clear that not all grantors (or their lawyers) have received the Court of Appeals' message, suggesting that the rule needs re-examination.
