Does the inventor need to know the science behind his invention?
• Operative invention is patentable though patentee does not know scientific principle on which it is based. Smith v Hall (1937) [101, n 122] ** • Fact that patentee has erroneous theory of his process does not defeat patent. Knick v Bowes “Seal Fast” Corp. (1928, CA8 Mo) [101, n 122] ** • It is not necessary that patentee understand scientific principles underlying his discovery so long as he makes sufficient disclosure to enable other persons skilled in art to practice invention.
