If one patent claim is composed of multiple technical details, can I use one of those details (not the whole claim, just a part of it) in my patent application, knowing that both are in the same business field (I am referring to my competito patent)?
If no, can I use the technical detail by adding other different technical details (related to my invention) to it?
PS: Please note that I am talking about a part of a patent CLAIM, not of a part of a whole patent application.
Thank you.
