Office Action

§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 . Specification The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed. The examiner suggests reference to renal stimulation and the use of a parasympathetic damping device. Claim Objections Claim 20 is objected to because of the following informalities: the word “indirect” should be replaced by the word “indirectly” for grammatical purposes. Appropriate correction is required. 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 8, 19 and 20 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. Regarding claim 8, the phrase "such as" renders the claim indefinite because it is unclear whether the limitations prior to and/or following the phrase are part of the claimed invention. See MPEP § 2173.05(d). In claim 19, reference to “dispatching number 10” is vague as the term does not appear to relate to standard medical terminology. Regarding claim 19, the phrase "preferably" renders the claim indefinite because it is unclear whether the limitations prior to and/or following the phrase are part of the claimed invention. See MPEP § 2173.05(d). A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claim 19 recites the broad recitation S2-S4, and the claim also recites S4 which is the narrower statement of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph: Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claim 20 is rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. It is unclear what further structural limitation is being set forth because the claim appears to recite an inherent property of the vasomotor tone (i.e., that it defines the flow in the renal artery and thereby indirectly the blood pressure) –a property that would already be present in claim 1. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Allowable Subject Matter Claims 1-7 and 9-18 are allowed. Regarding claim 1, the prior art of record fails to disclose a system for treating hypertension comprising the use of the signal damping device configured to be arranged at the parasympathetic nerve at a position between the stimulation device and the spinal cord, configured to at least partly counteract the electrical stimulation signal generated by the stimulation device. The applicant discloses that such a system reduces the effects of inadvertent stimulation to other parts of the body that are not a primary target of the stimulation. It is noted that Brennan ‘111 who discloses a renal neuromodulation system capable of use in hypertension treatment, would appear to teach away from the use of a parasympathetic damping device because it is taught that there is little parasympathetic innervation of the kidney (par. 0077). Claims 8 and 19 would be allowable if rewritten 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 and to include all of the limitations of the base claim and any intervening claims. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Harrison et al. ‘978 discloses a renal neurostimulation system capable of applying stimulation to both the sympathetic and parasympathetic system to control hypertension.
