R.I. Gen. Laws § 31-5.1-15
Actions arising out of any provision of this chapter shall be commenced within four (4) years next after the cause of action accrues. If a person liable under this chapter conceals the cause of action from the knowledge of the person entitled to bring it, the period prior to the discovery of his or her cause of action by the person so entitled shall be excluded in determining the time limited for the commencement of the action. If a cause of action accrues during the pendency of any civil, criminal, or administrative proceeding against a person brought by the United States, or any of its agencies, under the anti-trust laws, the Federal Trade Commission Act, 15 U.S.C. § 41 et seq., or any other federal act or the laws of the state related to anti-trust laws or to franchising, that action may be commenced within one year after the final disposition of that civil, criminal, or administrative proceeding.
