Eon Corp. IP Holdings LLC v. Silver Spring Networks, Inc., No. 15-1237 (Fed. Cir. 2016)Annotate this Case
Eon’s patents relate to a two-way interactive communication network system for enabling communications between local subscribers and a base station and describe various contexts in which the described networks might be useful: broadcast television programs; wireless facsimile services; pay-per-view services; when the subscriber unit is located in a location where it would otherwise lack ability to receive transmissions; meter reading; inventory control in soft drink dispensing machines; and site alarms for remote monitoring of open doors, fires, failure, temperature, etc. Eon sued SIlver Spring, a utility services network provider, and won an infringement verdict of $18,800,000. The district court reversed as to one of the three patents and remitted the award to $12,990,800. The Federal Circuit reversed, holding that no reasonable jury could have found that Silver Spring’s utility meters are “portable” and “mobile” in the context of the claimed invention; those meters do not infringe the two remaining patents.
