Ex parte King & Barton, 146 U.S.P.Q. (BNA) 590 (BNA) (Pat. Off. Bd. App. 1964).
Factual Background Edit
The claims in the application related to a special purpose computer arranged to mathematically process stored data. The processing was performed in accordance with a system of mathematical expressions free of parenthetical groupings, already known to mathematicians as "Polish Notation."
Board Ruling Edit
The Board ruled that the claims were not directed to the novel configuration of a computer which can process data expressed in Polish Notation, but that the claims merely set forth the result of the function accomplished by any computer operating on data in Polish Notation.
