Cooley is being sued in federal court in New Jersey for alleged negligent representation by Jason Gould and Gould Ventures, investors who claim the law firm duped them into backing a now-defunct startup called Carbon IQ, which did business as Rumby.

The investors filed the suit in the U.S. District Court for the District of New Jersey on Thursday. They claim that Cooley withheld information from them about Carbon IQ CEO Benjamin  Cantey's fraudulent activities, including document forgery, securities fraud and misrepresentation of financial information, and misappropriating investor funds. Gould Group and Gould, its founder, are requesting at least the $140,000 they invested in the company, plus attorney fees and punitive damages.
