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 . Response to Amendment/Arguments This office action is in response to applicant’s reply filed 2/20/26. Amended Claims 1-12, 14, 19-27 are pending. Regarding the previous drawing objections, these are moot in light of the cancellation of claim 15. Regarding the previous specification objections, these are moot in light of the cancellation of claim 15. Regarding the previous 112(b) rejections, these are moot in light of the cancellation of claim 15. Regarding the previous prior art rejection under 103 by Coad in view of Margaret, applicant has amended the claims to include previously indicated allowable subject matter thereby overcoming the prior art. Examiner notes a few matters in the claims merit attention. If applicant has any questions regarding this office action they are invited to contact the undersigned examiner before filing a response. Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 2/20/26 has been entered. Claim Objections Claims 9-12, 14, 24-27 are objected to because of the following informalities: Claim 9 should read “and --the-- reeling motor” since antecedent basis has already been established. Claim 10 recites “the inverted body” when examiner believes this should be “the inverted --portion--”. Claim 14 ends in a comma instead of a period (MPEP 608.01(m)). Claim 24 should read “and --the-- reeling motor” since antecedent basis has already been established. Claim 25 recites “the inverted body” when examiner believes this should read “the inverted --portion--". Appropriate correction is required. Those claims not specifically mentioned above are objected to by virtue of their dependence on an objected to claim. Claim Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and (C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Examiner notes: Claim 3 recites “a controlled pressure source configured to pressurize the pressure channel” which was considered for interpretation under 112(f) however “pressure source” was interpreted to be a term of art for a class of structures; Claim 19 was interpreted in the same manner. 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 9-12, 24-27 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 9 recites the limitation "the steering motor" in line 3. There is insufficient antecedent basis for this limitation in the claim. Claim 7 does introduce a “steering motor” but Claim 9 does not depend from Claim 7. Claim 11 recites “wherein the spool is positioned with spacing around the circumference around a circumference of the spool”. This is indefinite. “the circumference” lacks antecedent basis; given the duplication of language, it may be that by deleting “around the circumference” the claim is accurate. Claim 26 has the same issue. Claim 12 recites “a distal motor support frame”. This is indefinite. Claim 12 depends from Claim 9 which has already established “a distal motor support frame”. Claim 24 recites the limitation "the steering motor" in line 3. There is insufficient antecedent basis for this limitation in the claim. Claim 22 does introduce a “steering motor” but Claim 24 does not depend from Claim 22. Claim 27 recites “a distal motor support frame”. This is indefinite. Claim 27 depends from Claim 24 which has already established “a distal motor support frame”. Those claims not specifically mentioned above are rejected as being rendered indefinite by virtue of their dependence on an indefinite claim. Allowable Subject Matter Claims 1-8, 19-23 are allowed, while Claim 14 is objected to but would be allowable with an amendment to a period, and Claims 9-12 and 24-27 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.
