Only Result-Effective Variables Can Be Optimized A particular parameter must first be recognized as a result-effective variable ie a variable which achieves a recognized result before the determination of the optimum or workable ranges of said variable might be characterized as routine experimentation. It must however derive from the subject-matter as claimed not merely from some additional features which are mentioned only in the description. In Corkhill the claimed combination showed an additive result when a diminished result would have been expected.

In In re Antonie 559 F2d 618 195 USPQ 6 CCPA 1977 the CCPA held that a particular parameter must first be recognized as a result-effective variable ie a variable which achieves a recognized result before the determination of the optimum or workable ranges of said variable might be characterized as routine experimentation because obvious to try is not a valid rationale for an. From Stanford University where I studied graphite intercalation compounds at the Center for Materials Research. In Corkhill the claimed combination showed an additive result when a diminished result would have been expected.
