Uber Document Shows Ex-Google Engineer Possessed Secret Files

Google parent Alphabet Inc. has produced a long-anticipated document in the high-stakes legal battle with Uber Technologies Inc. that showed the ride-hailing company knew a former Google engineer had confidential Google files before buying his self-driving-car startup.

The report, however, stopped short of establishing that Uber possessed or used those files to jump-start its own driverless-car program—the allegation at the center of Alphabet’s lawsuit.
