Question. Like an inventor's journal and the PTO's Disclosure Program, can the day you gave your lawyer the drawings and description of your idea be used as a witnessed date of conceivement?
"Conception" not "conceivement." Or "invention," depending on what you are talking about. Anything that is(or can be) dated and dicloses the necessary information to prove "conception" of an invention can be used to show a date of conception. Invention, of course, requires both conception and reduction to practice -- but again, anything that fully discloses the invention, and is sufficient to show both conception and reduction to practice, can be used to establish the date of the invention.
It is typically assumed the the filing date of the invention is the date that the invention was, for lack of a better term, invented. Certainly a full disclosure to your patent attorney could be used to establish an earlier invention date if such an earlier date was needed.
