Looks like Uber isn't hurting for lawyers. After a few tens of millions, spending 10x more doesn't get 10x more chances in court or better arguments.

Uber might even be able to pay them with stock...

You can get an awful lot of lawyers with the $11 billion Uber has raised. When you're talking multi billion dollar companies facing off you can bet they each have the 2 most expensive lawfirms in the country representing them.

Uber is still losing money though and fast. Their entire competitive advantage is that they have a shit ton of VC funding to subsidize rides with. They've been able to survive this long because they've always been able to raise more money on the promise that they might not lose money someday, presumably when they have self-driving cars. Now that the lawsuit has put their future in question they're going to have a lot more trouble getting another round of funding.
