Hello, there is a unique name from a series of books (not central to the plot but none-the-less unique and in the series) and I was wondering if it was legal to use this unique name as a business name? So for example, if the unique name was "Unique Name Business", could I use "Unique Name Business" as the name of my business (also for Doing Business As)? There is no trademark for the name, though I am not sure if it was allowed due to it being in a body of work that is protected (trademark, copyright). Thanks for your time.
