1213.05(g) Marks with Design Elements Replacing Letters
Generally, when a design element replaces one or more letters (or a portion of a letter or letters) in a word that is merely descriptive, generic, or geographically descriptive, this combination of word and design element does not create a "unitary mark" if the word remains recognizable. Accordingly, the examining attorney must require a disclaimer of the merely descriptive, generic, or geographically descriptive word in such cases. See In re Clutter Control, Inc., 231 USPQ 588, 590 (TTAB 1986) .
If the wording to be disclaimed is otherwise registrable (i.e., not generic), applicant may submit a claim of acquired distinctiveness as to that portion of the mark under Trademark Act §2(f). The examining attorney must always separately determine whether an applicant has adequately shown acquired distinctiveness. See In re Venturi, Inc., 197 USPQ 714, 717 (TTAB 1977) .
The examining attorney must also assess whether the proposed mark might be unitary for other reasons (such as a compound or telescoped mark).
1213.05(g)(i) Marks with a Distinctive Design Replacing a Letter in Descriptive or Generic Wording
Marks with a distinctive design that replaces a letter or part of a letter are registrable on the Principal Register with a disclaimer of the merely descriptive, generic, or primarily geographically descriptive wording. For example:

Principal Register – Disclaimer of "WOOL"

Principal Register – Disclaimer of "INC." and "ANIMAL FOOD"

Principal Register – Disclaimer of "CLOTHING CO."

Principal Register – Disclaimer of "PARIS"

Principal Register – Disclaimer of "PONY"

Principal Register – Disclaimer of "FISH"

Principal Register – Disclaimer of "KIDS"

Principal Register – Disclaimer of "NUTRITION"

Principal Register – Disclaimer of "TOWELS"

1213.05(g)(ii) Marks with Merely Descriptive or Primarily Geographically Descriptive Designs Replacing Letters within Descriptive or Primarily Geographically Descriptive Wording
If the design that replaces a letter within descriptive or primarily geographically descriptive wording is itself merely descriptive or primarily geographically descriptive, or is otherwise nondistinctive, the examining attorney must require the applicant to amend to the Supplemental Register or seek registration on the Principal Register under §2(f) and to disclaim any generic wording. For example:

Disclaim "BANKERS ASSOCIATION" on Principal Register under §2(f) or on Supplemental Register

Disclaim "BUILDERS ASSOCIATION" on Principal Register under §2(f) or on Supplemental Register

Disclaim "CHECK CASHERS" on Principal Register under §2(f) or on Supplemental Register
1213.05(g)(iii) Marks with Accurate Pictorial Representations Replacing Letters in Merely Descriptive and Primarily Geographically Descriptive Marks
If the mark is otherwise merely descriptive or primarily geographically descriptive, and the design replacing a letter is an accurate pictorial representation of generic, merely descriptive, or geographically descriptive matter, the examining attorney must require the applicant to amend to the Supplemental Register or seek registration on the Principal Register under Trademark Act §2(f). The applicant must disclaim any generic wording or any accurate pictorial representation of generic matter. For example:

Disclaim "SOCCER BALLS" and the pictorial representation of the soccer ball on the Principal Register under §2(f) or on the Supplemental Register
1213.05(g)(iv) Unitary Marks with Design Elements Replacing Letters in Descriptive or Generic Wording
If literal and design elements in a mark are so merged together that they cannot be divided or regarded as separable elements, these elements may be considered unitary. For example, where the design element replacing a letter is merely one part of a larger design, the mark may be unitary, and no disclaimer of the descriptive or generic wording is required:
