Standard-setting organizations commonly adopt policies that govern the ownership of patent rights that apply to the standards they adopt (the patent policy). In the United States, the patent holder's agreement to adhere by the patent policy creates a legally binding contract, as the Court of Appeals for the Ninth Circuit ruled in Microsoft v. Motorola. One of the most common policies is to require a patent holder that voluntarily agrees to include its patented technology in the standard to license that technology on "reasonable and non-discriminatory terms" (RAND) or on "fair, reasonable, and non-discriminatory terms" (FRAND). The two terms are generally interchangeable; FRAND seems to be preferred in Europe and RAND in the U.S.
