Diamond v. Diehr, 450 U.S. 175 (1981) Notes
From Bill Goodwine's Wiki
converting synthetic rubber into cured precision products
need to know when to open molding press
- already had mathematical representation
- didnt have accurate way of knowing temp inside press to plug into equation and thus get desired result
- so patent is process of constantly measuring temp, and using computer program to say when to open press
REJECTED by PTO - claims drawn to nonstatutory subject matter CCPA Reverses, says patentable
- not patenting a mathematical formula, but a process that uses it
- for patent, formula must be applied in performing a patentable function
not unpatentable JUST BECAUSE uses a computer program, which is what patent office that rejected it said
- these guys wanted patent on a NEW PROCESS that employed mathematical formula, etc. not a patent just on the formula
