1213.01(a) Discretion in Requiring Disclaimer
When first incorporated in the Trademark Act in 1946, §6 stated that the Director shall require unregistrable matter to be disclaimed. Under the impetus of the mandatory word "shall," it became customary to require a disclaimer for every occurrence, in any type of combination, of every term or symbol which by itself might be refused registration in the first instance under the 1946 Act.
In 1962, §6 was amended to state that the Director may require the applicant to disclaim an unregistrable component of a mark otherwise registrable. The change from "shall" to "may" justifies the exercise of greater discretion by examining attorneys in determining whether a disclaimer is necessary. See also In re La. Fish Fry Prods., Ltd., 797 F.3d 1332, 116 USPQ2d 1262 (Fed. Cir. 2015) (stating that registration can be conditioned on disclaimer of an unregistrable component of a mark).
Examining attorneys should keep in mind the basic purpose of disclaimers, which is to indicate in the record that a significant element of a composite mark is not being appropriated apart from the composite. The examining attorney must not require that an element of a mark be disclaimed when a disclaimer would be unnecessary, e.g., when the form or degree of integration of an element in the composite makes it obvious that no claim is being made in any element apart from the composite.
