Federal Circuit Deems Written Description Requirement Satisfied if Specification Identifies the Claimed Invention in a Definite Way

The United States Court of Appeals for the Federal Circuit recently issued a ruling reversing a district court’s grant of summary judgment of non-infringement and invalidity for failure to satisfy the written description requirement. See CenTrak, Inc. v. Sonitor Techs., Inc., 2019 U.S. App. LEXIS 4442 (Fed. Cir. Feb. 14, 2019) (Before Reyna, Taranto, and Chen, Circuit Judges) (Opinion for the Court, Chen, Circuit Judge). The Court said the written description requirement does not require that the specification provide either examples or an actual reduction to practice. Instead, a constructive reduction to practice may be sufficient if the specification identifies the claimed invention in a definite way.
