I have an 8x5 binder and have adhered one additional item to it. I've also modified the paper that fits this binder, which fixes an existing issue. The binder provides use for a specific audience. Can I do a utility patent on this as a 'Manufacture'? I have not created any specific parts/pieces. It is a composition of several off the shelf items with two items that have not been used (with this binder) in this manner before.
As an additional note, any one can purchase all of these items, apply modification to paper and assembly everything without needing any special skills or machinery. But it is not an obvious assembly nor is it an item currently being sold.
