EON Corp., IP Holdings LLC v. AT&T Mobility LLC, No. 14-1392 (Fed. Cir. 2015)
Annotate this CaseEON’s patent, issued in 1997, is directed to software embodied in a “local subscriber data processing station” that operates to interconnect various interactive features of a television. The software allows “impulse purchase transactions with immediate payment,” audience participation voting, and sorting television programs by theme. EON alleges that “the modern iteration of the 757 Patent’s local subscriber data processing station is a smartphone with certain capabilities,” and, in 2010, sued smartphone manufacturers, cellular network providers, and smartphone content providers (FLO TV case). In 2011, EON filed a separate action (AT&T case). The cases were consolidated. The 757 patent went through two reexaminations. All claims, as amended, were confirmed in the second reexamination. The district court granted summary judgment to the FLO TV defendants, finding all of the means-plus-function claims in the patent invalid as indefinite. The parties in the AT&T case stipulated to final judgment of invalidity. The Federal Circuit affirmed.
