Waymo Dismisses Nearly All of the Patent Claims in Its Lawsuit Against Uber

This story has been updated with a statement from Uber.

The Alphabet-Uber legal fight continues.

Waymo, the Google self-driving project that spun out to become a business under Alphabet, filed a lawsuit against self-driving truck startup Otto and its parent company Uber for patent infringement and stealing trade secrets back in February. Now, Waymo has dismissed three of the four patent-infringement claims in the suit.

This comes after Waymo was encouraged to drop the claims following U.S. District Judge William Alsup’s request that both parties narrow their issues for the trial. Additionally, Waymo dropped all but one of the patent claims because Uber abandoned its “Spider” LiDAR design, which had reportedly infringed upon the Waymo patents.

The fourth patent claim, however, relates to a LiDAR design called, “Fuji,” that the ride-hailing giant continues to use, according to Bloomberg.

In terms of trade secrets, the lawsuit alleges that Uber executive and Otto founder Anthony Levandowski downloaded more than 14,000 confidential files, including proprietary Waymo technology designs, shortly before he resigned from his job at Google’s Waymo. Levandowski has since been fired from his position at Uber.

In a statement to Fortune, a Waymo spokesperson said, “We found after fighting for discovery a device created by Anthony Levandowski at Uber that infringed Waymo patents. Uber has assured the court in statements made under penalty of perjury that it no longer uses and will not use that device, so we have narrowed the issues for trial by dismissing the patent claims as to that device, with the right to re-file suit if needed.”

The spokesman added, “We continue to pursue a patent claim against Uber’s current generation device and our trade secret claims, which are not at all affected by this stipulated dismissal. We look forward to trial.”

An Uber spokersperson, on the other hand, said Waymo “has resorted to floating conspiracy theories not rooted in fact.” She added that “Waymo’s retreat on three of their four patent claims is yet another sign that they have overpromised and can’t deliver. Not only have they uncovered zero evidence of any of the 14,000 files in question coming to Uber, they now admit that Uber’s LiDAR design is actually very different than theirs.”

A court has ruled to allow Uber to depose Alphabet CEO Larry Page as part of the lawsuit. This story is developing.
