You'll note that if you click on each of the patents themselves, they appear under the name "Warner Bros.", and "Harry Potter and the Chariots of Light" is registered to both England and Deleware, where it was published. It also says it covers all the rights for a "paper manuscript" as well as movie stuff, so I think its a safe bet that's the next book title. The other names are listed under "Seasomething Films" or some rubbish like that.
