Discrepancies between provisional and complete specifications.

57.—A patent shall not be held to be invalid on the ground that the complete specification describes a further or different invention to that contained in the provisional specification if the invention therein described, so far as it is not contained in the provisional specification, was novel at the date when the complete specification was put in, and the applicant was the first and true inventor thereof.
