Office Action

§102 §112
DETAILED ACTION 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 . 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 1-7 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. Claim 1, line 3, “the outer wall” lacks antecedent basis. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-2 and 4-5 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Zhang et al (A flexible and implantable piezoelectric generator harvesting energy from the pulsation of ascending aorta: in vitro and in vivo studies). Zhang et al teaches an artificial blood vessel comprising: PNG media_image1.png 295 708 media_image1.png Greyscale a polymer tube (latex tube); and a piezoelectric vibration element (shown in figure (c )) which is fully capable of emitting and/or receiving vibration) which is disposed at one or both ends of the outer wall of the polymer tube (as depicted in figure (a)), and including a first electrode (Al) disposed on the outer wall of the polymer tube, a polymer piezoelectric layer disposed on the first electrode (PVDF), and a second electrode (Al) disposed on the polymer piezoelectric layer. Claim 2, the piezoelectric vibration element is fully capable of generating vibration by receiving electricity. Claims 4-5, Zhang et al teaches PVDF, therefore, inherently fulfills claim 4 from which claim 5 depends. [ Claims not rejected under prior art The closes prior art of record is considered to be Zhang et al as detailed above. However, Zhang et al fails to teach the combination of claims 1 and 3; and claims 1 and 6. All claims are currently rejected under 35 U.S.C. 112(b).
