Patent applicants want broad claim terms, whereas patent examiners want narrower claim terms. The US Supreme Court, in Nautilus v. Biosig (June 2014), has now explained the standard of review for claim indefiniteness – in a post-issuance circumstance, i.e., after the patent issues. According to the Supreme Court, Section 112 requires more than a district court being able to “ascribe some meaning” to the claim term. Further, Section 112 does not “tolerate imprecision just short of that rendering a claim ‘insolubly ambiguous’”. Therefore, the definiteness requirement under Section 112 is met when the “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.”
