Par Pharmaceutical, Inc. v. TWi Pharmaceuticals, Inc.

Holding an inventor may define specific terms used to describe invention, but must do so "with reasonable clarity, deliberateness, and precision" and, if done, must "'set out his uncommon definition in some manner within the patent disclosure' so as to give one of ordinary skill in the art notice of the change" in meaning

Section 103 - Conditions for patentability; non-obvious subject matter
