to determine if it is working correctly. The examiner in turn
relies upon Marino for the general teachings that it is known,
here in the automotive test system environment, to isolate
various portions of an electronic control system such as in
automobiles for testing them to determine faulty components.
The examiner characterizes this as a process of elimination.
The examiner takes the view that based on Marino’s general
teachings of a process of elimination by isolating vehicle
