Ownership & Inventorship

From the moment that an invention crystallizes in the mind of an inventor, an inchoate ownership right is created of which the inventor is the first owner. Anyone wishing to acquire that right must claim title through the inventor. The inventor is the person who conceives of a new and useful art, process, machine, manufacture or composition of matter, and reduces it to a definite and practical shape.
