1. List the elements sought to be protected and their interrelationships.
2. Analyze each element asking:
a) Is the element necessary for preserving functionality?
b) Is the element needed to distinguish over the prior art?
c) Can the element be generalized in a way that retains claim novelty?
d) Can elements be combined in a way that retains claim novelty?
3. Review the entire claim, discarding any words not absolutely necessary for functionality or novelty.
