Conception of an idea for an invention is an element relevant to determine priority of invention. However conception of an invention, though evidenced by disclosure, drawings, and even a model, is not patentable, confers no rights on an inventor, and has no effect on a subsequently granted patent to another, UNLESS THE INVENTOR FOLLOWS UP HIS/HER IDEA WITH REASONABLE DILIGENCE BY SOME OTHER ACT, such as an actual reduction to practice, or filing a patent application (Automatic Weighing Mach. Co. v. Pneumatic Scale Corp., 166 F.2d 288, 1909 C.D. 498, 139 O.G. 991 (1st Cir. 1909).
