807.04(a) Characteristics of Special Form Drawings
A "special form drawing" is a drawing that presents a mark comprised, in whole or in part, of special characteristics such as elements of design or color, style(s) of lettering, or unusual form(s) of punctuation.
All special form drawings must be of a quality that will reproduce satisfactorily for scanning into the USPTO’s database. If the drawing is not of a quality that will reproduce satisfactorily for scanning and printing in the Official Gazette and on the certificate of registration, the examining attorney must require a new drawing. If there is any doubt as to whether the drawing is acceptable, the examining attorney should contact the Office of Trademark Quality Review.
Pasted material, taped material, and correction fluid are not acceptable because they do not reproduce satisfactorily.
See TMEP §807.18 concerning mark drawing codes.
