Washington Trademark Amendment is a law passed in the state of Washington that provides additional protection to trademarked items. It expands the scope of trademark protection to include any item which is “distinguishable in any manner” from a trademarked item. This includes any item which is similar in some way to a trademarked item, including shape, color, pattern, or design. The Amendment also provides for the registration of multiple marks, and creates a presumption of infringement if the marks are “confusingly similar.” The Washington Trademark Amendment has two distinct types of amendments. The first type is the “Original Amendment” which was adopted in 2003. This amendment allows for the registration of multiple marks, and creates the presumption of infringement if the marks are “confusingly similar.” The second type of amendment is the “Supplemental Amendment” which was adopted in 2013. This amendment further expands the scope of protection by allowing trademarked items to be protected from “dilution”, which is the unauthorized use of a trademarked item in a way that diminishes its value or quality.
