In last year’s decision in Eon Corp. IP Holdings LLC v. Silver Spring Network, Inc. 815 F.3d 1314, 1320 (Fed. Cir. 2016), the Federal Circuit reversed the District Court’s jury instruction that the terms “portable” and “mobile” should be given their “plain and ordinary meaning.” During claim construction at the District Court, Eon argued that “portable” and “mobile” did not need construction and that the terms could simply be given their plain and ordinary meaning. Id. at 1317. Silver Springs argued that the terms ought to be construed, but the District Court agreed with Eon and found that the meanings of those terms are clear and would be readily understandable to a jury. Id. However, the Federal Circuit held that a determination that a particular term needs no construction may be inadequate when a term has more than one meaning.
