Office Action

§112
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Allowable Subject Matter Claims 1-10,13-18 are allowed Claim Rejections - 35 USC § 112 Claims 11-12,19-26 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. As to claim 11, “engagement feature protruding” (italics added, line 5) and “as stop feature” are indefinite as it’s undetermined if such features are structure, purely functional or a means plus functional limitation. As to claim 21, it’s not clear in what manner the verb “associating” (line 3) is a step. Is such a metal step of associating the in-line portion with a flow line? If so what might the step be? Could the step mean mental recognition/acknowledgement that the in-line portion and flow line are present? If not, what other action (- - providing - - ?) might lines be attributed to lines 3-5? What is Applicant’s intent? As to claim 19, “stop feature” is indefinite. What meaning is to be attributed to such?
