After a three-year battle in which he spent up to $1000 an hour on lawyers, Swildens ended up selling Speedera at a discount to Akamai for $130 million.

The experience left Swildens with a working knowledge of intellectual property battles in the tech world, and a lingering soft spot for others facing hefty patent claims. So when he heard in February that the world's second-most valuable company, Alphabet, was launching a legal broadside at Uber's self-driving car technology, he put himself in then-CEO Travis Kalanick's shoes: "I saw a larger competitor attacking a smaller competitor...and became curious about the patents involved."

In its most dramatic allegations, Waymo is accusing engineer Anthony Levandowski of taking over 14,000 technical confidential files to Uber. But the company also claimed that Uber's laser-ranging lidar devices infringed four of Waymo's patents.

"Waymo developed its patented inventions...at great expense, and through years of painstaking research, experimentation, and trial and error," the complaint read. "If [Uber is] not enjoined from their infringement and misappropriation, they will cause severe and irreparable harm to Waymo."

But Swildens had a suspicion. He dug into the history of Waymo's lidars, and came to the conclusion that Waymo's key patent should never have been granted at all. He asked the US Patent and Trademark Office (USPTO) to look into its validity, and in early September, the USPTO granted that request. Days later, Waymo abruptly dismissed its patent claim without explanation. The USPTO examiners may still invalidate that patent, and if that happens, Waymo could find itself embroiled in another multi-billion-dollar self-driving car lawsuit—this time as a defendant.
