Trademarking Book Names
Many people have called about trademarking names of books. It seems like a great idea. However, as a general rule, it’s not possible to trademark individual titles. So, if you’ve just written one book, in most cases, you will not be able to secure federal trademark registration.
However, trademark protection is available to series of books. If you’ve written more than one book under the same name you’re in luck. Book series such as “The Hardy Boys,” “Harry Potter,” and all those “Idiot’s Guide” books have been able to secure federal trademark protection.
