So you have three different legal intellectual property claims that you need to work with:
Copyright : Copyrights are published works and copyrights are created automatically on publishing. They protect unique works of art and are transferable by the original artist. For example, Harry Potter and the Chamber of Secrets is a copyrighted manuscript created by J.K. Rowling. The cover art (for the American editions) was created by Mary GrandPré though she likely does not own the copyrights as they would have been ceded to Rowling and the Publishers who make the books.
Trademarks: Unique logos or styles or designs that are protected by a trademark. A "TM" letter mark denotes the trademark exists on the product, but an "R" in a circle is used to denote it's a registered trademark by a patent office. While we discussed in the last example ownership of different copyrights related to Harry Potter, the actual American published book with the manuscript, the cover art, and the distinct lettering of the word "Harry Potter" (where the P is formed by a lightning bolt) are trademarks of the book and the product as a whole.
Patent: Patents are issued for physical designs and almost always describe a working process of a products, formulas, and things that can be technically described. Continuing our Harry Potter theme, while Rowling holds intellectual copyrights and trademarks, she does not own the patent for the ride "Flight of the Hippogriff at Universal Studio's Islands of Adventure. The ride is a mass produced roller coaster made by Verkoma Rides Manufacturing. Specifically it is a Verkoma 355m Junior Rollercoaster and shares a track layout and vehicle assembly not only with her sister ride in Universal Studios Japan, but also several other rollercoasters with various names throughout the world. While the Harry Potter trappings of Hippogriff are not their own, the layout of the track, the block sections, it's vehicle specs and mechanical workings, are all patents owned by Verkoma.
