As the Waymo v. Uber trial draws nearer, the two companies are jockeying for position, each hoping to emerge victorious after a possible October courtroom brawl. A key part of that is damages. Waymo's massive damage request is only starting to become clear.

Last week, an Uber attorney said during a court hearing that Waymo was seeking $2.6 billion—for a single trade secret. In court papers filed on Friday, though, Waymo lawyers took issue with that calculation.

Waymo's new filing is mostly about defending the qualifications and positions of its damages expert. In a footnote, though, the company says that Uber's courtroom statement that Waymo wants $2.6 billion for a single trade secret is flat-out false.

"Waymo is asking for $1.859 billion for Trade Secret 25 (not $2.6 billion) and less for the remaining trade secrets," Waymo lawyers write. "Furthermore, Waymo's numbers are not additive; if the jury finds Defendants misappropriated every asserted trade secret, Waymo still only seeks $1.859 billion."

The brief defends Waymo's methods of calculating damages, saying it relies on "Uber's own estimate of how valuable the technology was to Uber at the time of acquisition."

Waymo lawyers also point out that the valuation of Trade Secret 90, which Uber has sought to throw out, is based on cash paid for a company called Tyto, which was ultimately acquired by Otto and then by Uber. In the new brief, Waymo makes explicit its view that ex-Waymo engineer Anthony Levandowski was "siphoning off Google trade secrets to Tyto" even while he was working at Google.

Financial damages are just one part of Waymo's case. The company will also be seeking a court injunction that could limit Uber's ability to work on self-driving cars, which could be even more damaging to Uber's business prospects.

Waymo sued Uber in February, accusing Uber of using Waymo's trade secrets in Uber's self-driving car technology. Lawyers for Waymo say that Levandowski, who was head of Uber's self-driving car project, illegally downloaded more than 14,000 files just before he left his job at Google. After leaving Google, Levandowski founded his own startup, Otto. He sold that company to Uber in mid-2016 for $680 million.

Uber has denied using any trade secrets, which it says never made it to Uber servers. Levandowski, who is not a defendant in the case, was fired from Uber after he wouldn't cooperate with court-ordered discovery.

Waymo has asked to delay the trial. The company argues that it doesn't have enough time to go through evidence that Uber handed over only recently, including the due diligence report about the acquisition of Otto. Uber is asking for the trial to begin, as scheduled, on October 10.

US District Judge William Alsup has yet to issue a ruling regarding allowable damages or the trial date.
