Office Action

§112 §DP
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 disclosure is objected to because, in para. [0001] of the filed specification, U.S. Pat. No. 12,096,940 is not cited as being issued from U.S. Pat. App. No. 17/176,634. Appropriate correction is required. Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” etc. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided. The abstract of the disclosure is objected to because it uses “are described,” which a phrase that can be implied. A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b). Claim Interpretation - 35 USC § 112 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. Use of the word “means” (or “step for”) in a claim with functional language creates a rebuttable presumption that the claim element is to be treated in accordance with 35 U.S.C. 112(f) (pre-AIA 35 U.S.C. 112, sixth paragraph). The presumption that 35 U.S.C. 112(f) (pre-AIA 35 U.S.C. 112, sixth paragraph) is invoked is rebutted when the function is recited with sufficient structure, material, or acts within the claim itself to entirely perform the recited function. Absence of the word “means” (or “step for”) in a claim creates a rebuttable presumption that the claim element is not to be treated in accordance with 35 U.S.C. 112(f) (pre-AIA 35 U.S.C. 112, sixth paragraph). The presumption that 35 U.S.C. 112(f) (pre-AIA 35 U.S.C. 112, sixth paragraph) is not invoked is rebutted when the claim element recites function but fails to recite sufficiently definite structure, material or acts to perform that function. Claim elements in this application that use the word “means” (or “step for”) are presumed to invoke 35 U.S.C. 112(f) except as otherwise indicated in an Office action. Similarly, claim elements that do not use the word “means” (or “step for”) are presumed not to invoke 35 U.S.C. 112(f) except as otherwise indicated in an Office action. 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 1-14 and 17-19 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. With respect to base claim 1, “the neck” lacks antecedent basis. With respect to base claim 11, it is not definite as to the function or intended use of the “fixation element.” Is the element for fixing the implant to the patient’s vasculature, for construction of the implant, or for another purpose? Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 11-14, 17-19, and 21-23 are rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 or 3 of U.S. Patent No. 9,078,658 in view of Quick et al. (U.S. Pat. App. Pub. No. 2014/0005714). U.S. Pat. No. 9,078,658 claims the invention substantially as claimed in the present application. However, the patent does not explicitly claim that the device comprises a permeable implant including a plurality of elongate filaments woven together in a tubular braid, and a fixation element comprising hooks, barbs, protrusions, microfeatures, texturing, bioadhesives (or a bioadhesive coating), or combinations thereof. Quick et al. teach, at least in figures 3 and 6A and para. [0058] and [0071]; a woven, permeable implant (10) formed as a tubular braid. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention, in view of Quick et al., to modify the implant of U.S. Pat. No. 9,078,658, so that it comprises a tubular braid. Such a modification would allow the implant to be collapsible for delivery in a catheter and uniformly and radially expandable for deployment within an aneurysm or body cavity. Quick et al. further teach, in para. [0062] and [0065], that the implant (10) may include a fixation element (14) on the surface of the implant, wherein the element may comprise hooks, barbs, protrusions, microfeatures, texturing, bioadhesives (or a bioadhesive coating), or combinations thereof. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention, to modify the implant of U.S. Pat. No. 9,078,658, so that it includes a fixation element or bioadhesive or bioadhesive coating. Such a modification would allow the implant to be securely retained within an aneurysm or body cavity. Allowable Subject Matter Claims 1-10 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 following is a statement of reasons for the indication of allowable subject matter: With respect to base claim 1, none of the prior art of record, alone or in combination, discloses a method for treating a cerebral aneurysm in a patient's vasculature, comprising, inter alia, the steps of: advancing a resilient self-expanding permeable implant coupled to a pusher within a catheter to the cerebral aneurysm within the patient's vasculature, wherein the permeable implant is in a radially constrained elongated state in a lumen of the catheter, and wherein the permeable implant comprises a plurality of elongate filaments that are woven together in a tubular braid, the permeable implant comprising at least some filaments consisting of nitinol and at least some composite filaments, the composite filaments comprising drawn filled tube wires comprising an external nitinol tube and a highly radiopaque material concentrically disposed within the external tube, and wherein the permeable implant has at least about 40% composite filaments relative to a total number of filaments, and wherein a total number of filaments is about 10 to about 300; and deploying the permeable implant into an expanded state having a longitudinally shortened configuration relative to the radially constrained state within the cerebral aneurysm such that a portion of the permeable implant spans a neck of the cerebral aneurysm; wherein the method further includes delivering embolic material into the cerebral aneurysm adjacent a portion of the permeable implant that spans the neck. As allowable subject matter has been indicated, applicant's reply must either comply with all formal requirements or specifically traverse each requirement not complied with. See 37 CFR 1.111(b) and MPEP § 707.07(a). Conclusion Any inquiry concerning this communication should be directed to Julian W. Woo at telephone number (571)272-4707.
