Protection of Book Titles (Trademark) Law and Legal Definition

Generally, book titles are not protected under trademark law unless they are part of a series. The title of a single creative work is not registrable on either the Principal or Supplemental Register. However, even if the book title doesn't belong to a series, it can theoretically receive trademark protection if the title qualifies as a trademark and has acquired a secondary meaning. Even if the book title belongs to a series, secondary meaning is required if the series title itself is descriptive of the general contents of the series.
