The “principle of operation” referred to by Appellants relates to the “basic principles” under which the prior art device was designed to operate. In re Ratti, 270 F.2d 810, 813 (CCPA 1959). Under In re Ratti, “a change in the basic principles” refers to change that is fundamental in scope so as to relate to scientific or technical principles under which the invention is designed to operate. We are not persuaded that a “change in the basic principles” occurs by making Liang ’955’s exhaust orifices 48 smaller when Liang ’955’s device, even as modified by Parker, continues to exhaust cooling fluids.
