Sonix Technology Co., Ltd. v. Publications International. No. 2016-1449 Fed. Cir. Jan. 5, 2017 Opinion by Circuit Judge Lourie with Circuit Judges O’Malley and Taranto. Sonix appealed from the district court’s grant of summary judgment holding certain claims of its patent invalid. The district court concluded that the term “visually negligible” rendered the asserted claims indefinite under 35 U.S.C. § 112 ¶ 2. The United States Court of Appeals for the Federal Circuit (Federal Circuit) reversed. The Sonix patent purports to improve on conventional methods of encoding information on the surface of an object by rendering a graphical indicator (e.g., a matrix of small dots) “visually negligible.” An optical device reads the graphical indicator and outputs additional information.
