1202.02(c)(i)(C) Drawings in §44 and §66(a) Applications
For trade dress marks in §44 and §66(a) applications, an amendment of the drawing to depict functional or incapable matter in broken or dotted lines is permitted and generally not a material alteration of the mark. See TMEP §§807.08 and 1904.02(k). Although the mark in a §44 or §66(a) application cannot be amended, a change in the manner in which the mark is depicted may be permitted, in order to comply with the United States drawing requirements. See TMEP §1011.03 regarding amendment of marks in §44 applications and §1904.02(j)-(k) regarding amendment of marks in §66(a) applications. For instance, since functional matter is not considered source indicating and is never part of the mark, displaying it in broken or dotted lines shows placement of the functional matter in relation to the registrable portions of the mark.
Similarly, in §44 or §66(a) applications, amendments to delete extraneous matter from photographs, or amendments of drawings from photographs to illustrated renderings showing elements of the mark in dotted or broken lines, will be accepted and will not be considered a material alteration of the mark.
