Anthony Levandowski

Uber Technologies Inc goes before a U.S. judge on Wednesday to fight for the right to continue work on its self-driving car program, the latest phase in a courtroom battle over trade secrets that threatens to topple a central pillar of Uber's growth strategy.

The ride-services company is contesting a lawsuit by Alphabet Inc's self-driving car unit, Waymo, which accused former Waymo engineer and current Uber executive Anthony Levandowski of taking technical secrets from Waymo and using them to help Uber's self-driving car development.
