Is ‘Plain and Ordinary Meaning’ a Viable Proposed Claim Construction After the Federal Circuit’s Decision in Eon?

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.

CAFC overturns $18 million verdict because jury improperly left to determine claim scope

Following a five-day trial, the jury found the asserted claims valid and infringed, and awarded Eon $18,800,000. In determining only that the terms should be given their plain and ordinary meaning, the district court left the ultimate question of claim scope unanswered, and improperly left it for the jury to decide. Instead of remanding, the Court independently found that, when read in their appropriate context, the terms “portable” and “mobile” could not be construed as covering the accused products at issue. The jury’s infringement finding was reversed.
