A claim describes the invention sought to be protected, and is found at the end of every patent specification. The specification must conclude with a claim specifically pointing out and distinctly claiming the subject matter which the applicant regards as the invention. Patent protection is analogous to that of a real property deed, i.e., described in metes and bounds. The claim(s) must conform to the invention as set forth in the body of the specification exclusive of all other claims. The claim’s terms and phrases must find apparent support or antecedent basis in its description so that the meaning of said terms may be ascertainable by reference to the description [CFR§1.58(a)].
