Office Action

§112
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . This Office action is in response to the communication filed 8-24-26. Claims 1, 4-8, 17-19, 23, 24, 27-34 are pending in the instant application. Claims 18, 19, 23, 24, 30, 31 are withdrawn as being drawn to non-elected inventions or species. Claims 1, 4-8, 17, 27-29, 32-34 have been examined on their merits as set forth below. Response to Arguments and Amendments Withdrawn Rejections Any rejections not repeated in this Office action are hereby withdrawn. New Rejections 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. Claim 27 is 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 27 is not further limiting than claim 1, from which it depends. The following phrase is unclear: wherein the base sequence of the single-stranded antisense oligonucleotide is a base sequence complementary to at least one target region of the same base length as the single-stranded antisense oligonucleotide present in the base sequence as set forth in SEQ ID NO: 1 or SEQ ID NO: 2 Appropriate clarification is required. The following is a quotation of the first paragraph of 35 U.S.C. 112(a): IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1, 4-8, 17, 27-29, 32-35 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for pre-AIA the inventor(s), at the time the application was filed, had possession of the claimed invention. The breadth of the claims: The claims are drawn to compositions comprising single stranded antisense oligonucleotides between 12 and 30 nucleotides, or 14-22-mers, comprising fully modified wing regions ranging from 1-5 nucleic acids, and a gap region between 5 and 20 nucleobases, which modified 3’ wing region optionally comprises 2’-MOE, LNA, AmNA, GuNAA or scpBNA, and which modified 5’ wing region optionally comprises 2’-MOE, LONA, AmNA, GuNA or scpBNA, which oligonucleotide optionally further comprises a natural nucleotide bonded to the 3’ end of the 3’ wing region. Teachings in the specification: The specification teaches the in vitro screening of antisense having 100% homology to the target gene for target gene inhibition (See, e.g., pages 60-81, 86-98, 113, 114 of the specification). The specification fails to provide the broad genus comprising the varied lengths of wing and gap regions claimed, and varied modification patterns claimed, and further whereby target gene inhibition is provided. . The specification, prior art and claims do not adequately describe the genus of modulatory agents claimed, and/or fail to provide a representative number of species, and do not indicate what distinguishing attributes are concisely shared by the members of this genus, and further whereby inhibition has been provided. For the reasons stated above, the instant rejection for lacking adequate written description is proper. Allowable Subject Matter SEQ ID No. 416 appears free of the prior art searched and of record. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action. Certain papers related to this application may be submitted to Art Unit 1637 by facsimile transmission. The faxing of such papers must conform with the notices published in the Official Gazette, 1156 OG 61 (November 16, 1993) and 1157 OG 94 (December 28, 1993) (see 37 C.F.R. ' 1.6(d)). The official fax telephone number for the Group is 571-273-8300. NOTE: If Applicant does submit a paper by fax, the original signed copy should be retained by applicant or applicant's representative.
