Michael Ross was fired and blamed for two corporate scandals at Atmel Corp. — but now the former general counsel is fighting back.

Ross has filed a lawsuit, claiming the San Jose, Calif., semiconductor company ruined his reputation when it pointed the finger at him and others for the company’s stock option backdating problems, which led to a $125 million financial restatement. Having been fired along with other Atmel executives in 2006 after an investigation into the misuse of travel funds, Ross became an easy scapegoat when the company faced a mounting backdating mess a year later, his lawyers say.
