808.03(e) Amending Descriptions
Generally, amending the description of the mark is liberally permitted, so long as the drawing supports the description. In rare cases where the amendment of the description constitutes a material alteration of the mark on the drawing or of the description filed with the original application, amendment will not be permitted. See 37 C.F.R. §2.72; In re Thrifty, Inc., 274 F.3d 1349, 61 USPQ2d 1121 (Fed. Cir. 2001). See TMEP §§807.14–807.14(f) regarding material alteration.
