A grinding four-year worker lawsuit against the company led by tech billionaire Thomas Siebel has come a step closer to conclusion, with a San Jose jury this week delivering a verdict against a former salesman for C3 IoT who claimed that Siebel shortchanged him on commissions.

C3 IoT, an industry-facing internet of things company, convinced a majority of the jury that former salesman Gregg Carman did not have a reasonable expectation of being paid several hundred thousand dollars extra in commissions—defeating his claim under a legal theory known as “quantum meruit.” C3 is represented by Quinn Emanuel Urquhart & Sullivan.
