Sec. 2.171. New certificate on change of ownership.
(a) Full change of ownership. If the ownership of a registered mark changes, the new owner may request that a new certificate of registration be issued in the name of the new owner. The assignment or other document changing title must be recorded in the Office. The request for the new certificate must include the fee required by §2.6(a)(8) and be signed by the owner of the registration, someone with legal authority to bind the owner ( e.g. , a corporate officer or general partner of a partnership), or a practitioner qualified to practice under §11.14 of this chapter. In a registered extension of protection, the assignment must be recorded with the International Bureau of the World Intellectual Property Organization before it can be recorded in the Office (see §7.22).
(b) Partial change of ownership.
(1) In a registration resulting from an application based on section 1 or section 44 of the Act, if ownership of a registration has changed with respect to some but not all of the goods and/or services, the owner(s) may file a request that the registration be divided into two or more separate registrations. The assignment or other document changing title must be recorded in the Office. The request to divide must include the fee required by §2.6(a)(8) for each new registration created by the division, and be signed by the owner of the registration, someone with legal authority to bind the owner ( e.g., a corporate officer or general partner of a partnership), or a practitioner qualified to practice under §11.14 of this chapter, in accordance with §2.193(e)(2) of this chapter.
(i) When the International Bureau of the World Intellectual Property Organization notifies the Office that an international registration has been divided as the result of a change of ownership with respect to some but not all of the goods or services, the Office will construe the International Bureau's notice as a request to divide. The Office will record the partial change of ownership in the Assignment Services Branch, and divide out the assigned goods/services from the registered extension of protection (parent registration), issue an updated certificate for the parent registration, and publish notice of the parent registration in the Official Gazette.
(ii) The Office will create a new registration number for the child registration, and enter the information about the new registration in its automated records. The Office will notify the new owner that the new owner must pay the fee required by §2.6 to obtain a new registration certificate for the child registration. It is not necessary for the new owner to file a separate request to divide.
(iii) The Office will not divide a registered extension of protection unless the International Bureau notifies the Office that the international registration has been divided.
