On October 15, 2011, the USPTO issued the eighth edition of the TMEP, which provides USPTO trademark examining attorneys, trademark applicants, and attorneys and representatives for trademark applicants with a reference on the practices and procedures for prosecution of applications to register marks in the USPTO. The eighth edition incorporates USPTO trademark practice and relevant case law reported prior to September 1, 2011. The policies stated in this revision supersede any previous policies stated in prior editions, examination guides, or any other statement of USPTO policy, to the extent that there is any conflict. The eighth edition also includes a collaboration tool, offered through a program called IdeaScale®, which permits the user community to provide public comments that are accessible to both the user community and the Office. The collaboration tool is currently open to Chapters 500, 900, and 1900.
