Patentable Subject Matter

"Congress intended [patentable] statutory subject matter to include anything under the sun that is made by man."  Diamond v. Chakrabarty, 447 U.S. 303, 309 (U.S. 1980) citing S. Rep. No. 1979, 82d Cong., 2d Sess., 5 (1952); H. R. Rep. No. 1923, 82d Cong., 2d Sess., 6 (1952).  This excludes mathematical formula and physical phenomena which inherently exist and thus, cannot be patented.
