THE QUALITY of patents should be celebrated, not condemned, but today's USPTO measures its performance in terms of quantity (e.g. number of grants), not quality. We have just explained who benefits from such abundance of legally-toothless patents.
"Ars Technica's coverage went with a headline that called him "Vigilante engineer" (negative connotation, as though he's armed or something)."Earlier this week there were many news articles like "Engineer spends $6,000 invalidating Waymo's lidar patents" and "Random engineer spends six grand to block Waymo’s lidar patents" (he is not "random"). To quote the latter:
The 936 patent was key in Waymo’s battle against Uber in a legal battle running since 2016 in which Waymo accused Uber of using allegedly stolen intellectual property. Waymo, owned by Alphabet, ended up prevailing, partly thanks to its 936 patent. In the end, Uber had to pay Waymo $245 million worth of equity to settle the lawsuit.
But now it turns out Uber could have saved a huge chunk of cash since the lone engineer’s actions have resulted in most of the 936 patent being ruled invalid. “As I investigated the 936 patent, it became clear it was invalid due to prior art for multiple reasons,” Swildens said. “I only filed the reexamination because I was absolutely sure the patent was invalid.”
A lone engineer has overturned most of a foundational patent covering Waymo's lidar laser ranging devices.
Eric Swildens managed to get the US Patent and Trademark Office (USPTO) to reject all but three of 56 claims in Waymo's 936 patent.
The USPTO found that some claims replicated technology described in an earlier patent from lidar vendor Velodyne, while another claim was simply "impossible" and "magic."
What makes this surprising is that Uber spent a fortune losing a court case against Waymo over this patent after a Waymo engineer was inadvertently copied on an email from one of its suppliers to Uber, showing a lidar circuit design that looked almost identical to one shown in the 936 patent.
