The title of a single book or creative work* is not registrable on the Principal or Supplemental Register. The name of a series of books or creative works may be registrable if it identifies or distinguishes the source of the goods. However, a term used in the title of a series of books is not registrable if it merely identifies a character in the books. Here are some examples given in Section 1202.08 of the Trademark Manual of Examination Procedure:
If you are the author of a book and wish to have a registered trademark for the title of the book some thought needs to be given about how to make that title part of a book series. More detail about trademark registration can be found on our website >> here. Our trademark attorneys can answer any questions if you need help.
* Examples of “single creative works” include books, videotapes, films and theatrical performances. (TMEP §1202.08)
