Applera Corp. v. Enzo Biochem, Inc.

Issue: Whether the Federal Circuit's standard for finding that a patent’s claims are “definite,"? which is met as long as the language of a claim is not “insolubly ambiguous"? or is capable of being construed, is consistent with the language of 35 U.S.C. § 112, which provides that the patent must include “claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.”?
