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 . DETAILED ACTION SPECIFICATION OBJECTION Updated information for parent applications 16/924,096 and 14/784,747 in par. [0001] of the specification is needed since both applications became US Patents. Submission of a whole new paragraph is suggested. . Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 154-162, 165, 166, 172-175 and 179-183 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. The recited “the aliphatic polyether polyurethane” in line 4 of claim 154 would lack an antecedent basis. The recited polyurethane as the polymer of claim 158 would improperly broaden scope of claim 154 in which the aliphatic polyether polyurethane is recited. Other claims depend from the indefinite claim 154 would be also indefinite. EXAMINER’S COMMENT Claims 154-162, 165, 166, 172-175 and 179-183 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Raad et al. (US 2012/0064372 A1) teach CVCs (i.e., central venous catheters, see [0004]) treated with a formula comprising NaOH (i.e., alkalizing agent), chlorhexidine, minocycline, rifampin, methanol (i.e., lower alcohol) and butyl acetate (i.e., penetrating agent) in [0084-0097]. Darouiche et al. (US 5,624,704) teach polyurethane vascular catheters treated with a formula comprising NaOH (i.e., alkalizing agent), chlorhexidine, minocycline, rifampin, methanol (i.e., lower alcohol) and butyl acetate (i.e., penetrating agent) in example 1. The above prior art and any combination of the prior art of record failed to teach or suggest the instantly recited step (b) utilizing a neutralizing solution.
