Uber Technologies, Inc. v. X One, Inc., No. 19-1164 (Fed. Cir. 2020)
Annotate this Case
X One’s patent describes a “Buddy Watch application” that allows a mobile device user to add other mobile device users to her “Buddy List.” A user may set up “instant buddies.” For example, a stranded motorist may wish to be instant buddies with the driver of a tow truck, allowing each phone to show the location of the other phone on its moving map. Uber sought inter partes review asserting that claims of the patent were obvious, 35 U.S.C. 103, in view of prior art that generally describes transmitting location information between mobile devices. The Patent Trial and Appeal Board held the claims were not unpatentable.
The Federal Circuit reversed. The Board erred in determining that the combination of prior art does not render obvious the limitation “software . . . to transmit the map with plotted locations to the first individual.” Because terminal-side plotting and server-side plotting, as described in prior art, would have been two of a finite number of known, predictable solutions at the time of the invention of the patent, a person of ordinary skill would have faced a simple design choice between the two, and would have been motivated to combine the teachings of prior art to achieve the limitation.
