When Uber Technologies Inc. retained Susman Godfrey partner Bill Carmody last year in its knock-down, drag-out fight against Waymo, trial was scheduled to start in just two months. Uber already had retained two large defense law firms from the start, but it was looking for a lead lawyer at trial.

While Uber’s existing defense team had done a good job of working the case to trial, “We felt it was important to have someone in the leading position who was a pure trial lawyer—someone whose core skill was persuading a lay jury in a complex business case,” said Bradford Berenson, general counsel at private equity firm TPG, which has a seat on Uber’s board.
