The fact that two sister corporations are controlled by a single parent corporation does not mean that they are related companies. Where two corporations are wholly owned subsidiaries of a common parent, use by one sister corporation is not considered to inure to the benefit of the other, unless the applicant sister corporation exercises appropriate control over the nature and quality of the goods or services on or in connection with which the mark is used.
