Not Step-Plus-Function

Recitation of “the method comprises the steps of,” in preamble of claim for cardiac stimulation method, does not convert each ensuing step into step-plus-function limitation under 35 U.S.C. § 112, sixth paragraph, since method claims necessarily recite steps, and use of words “steps of” in preamble does not create presumption of step-plus-function from.  The absence of the language “step for” creates presumption that each ensuing step is not step-plus-function form.  (Cardiac Pacemakers Inc. v. St. Jude Medical Inc., 72 USPQ2d 1333, CA FC, 8/31/04).
