The basic law relative to § 112, ¶6 explains that a decision on whether a claim is indefinite under § 112, ¶ 6 requires a determination of whether those skilled in the art would understand what is claimed when the claim is read in light of the specification. Traditionally, claim terms are typically given their ordinary and customary meaning as understood by one of ordinary skill in the pertinent art. The question with means-plus-function claiming, however, is whether evidence from that mythical individual skilled in the art is even admissible. No structure in the specification means the person of skill in the art cannot save the disclosure by understanding. Thus, means-plus-function claims are largely valid at the mercy of a federal judge who in all certainty is not one of skill in the art and who likely has an aversion to such claiming techniques because they prefer dealing with tangible structure.
