SAN FRANCISCO — Lawyers for Google Inc. driverless car unit Waymo are contradicting the damages number given by Uber's lead trial attorney in the legal battle between the Silicon Valley giants, who said last week that Waymo was seeking $2.6 billion for one trade secret.

In a filing on Sept. 22, Waymo lead attorney Charles Verhoeven of Quinn Emanuel Urquhart & Sullivan said that figure is “false” and that Waymo is actually seeking a damages value for that trade secret (known as Trade Secret 25) that is far lower—$1.859 billion to be exact.

Verhoeven also explained that $1.859 is the maximum amount of damages that Waymo is seeking, because the damages numbers are not “additive.” In other words, even if the jury finds that Uber Technologies Inc. stole all of Waymo's asserted trade secrets, “Waymo still only seeks $1.859 billion.”
