Material Alteration Law and Legal Definition
Material alteration is change of a mark made after a trademark application is submitted. The mark will be altered from that shown in the original application. Material alteration of a mark is considered as a ground for rejection of a proposed amendment to an application. Pursuant to 37 CFR 2.72, any amendment of the mark in an application that materially alters the mark is prohibited. A materially altered mark may have to be re-published, to fairly present the mark for opposition.
