Office Action

§103 §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 . Claim Objections Claim 1 is objected to because of the following informalities: the term “samidorpan” in line 15 appears to be a typographical error and should read “samidorphan”. Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (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. Claim 1 is 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 applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. While the present specification discloses silicon dioxide, the present specification does not appear to provide support for the limitation “microcrystalline silicon dioxide” recited in claim 1. 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 1 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 1 recited the limitation “microcrystalline silicon dioxide” in lines 4-5. It is not entirely clear whether this limitation is intended to read as such. This is vague in view of the limitation “microcrystalline cellulose” recited in claim 7 and so as in the present disclosure. Further clarification is requested. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 1-7 are rejected under 35 U.S.C. 103 as being unpatentable over Sun et al. (Clinical Therapeutics/Volume 40, Number 11, 2018), in view of Turkyilmaz et al. WO 2019/190427A2. Sun teaches a method for treating schizophrenia comprising safely administering to the patient in need thereof an oral dosage form comprising combination of olanzapine and samidorphan. See Abstract. Oral dosage form comprising a fixed dose an immediate release bilayer tablet for once a day with one layer comprising olanzapine and one layer comprising samidorphan in a dosing between 10mg/10mg and 10mg/20mg, respectively. See page 1846. Sun does not teach the claimed tablet excipients. However, tablet comprising the claimed tablet excipients is well known in the art. See for example the teaching in Turkyilmaz, which teaches an immediate release combination of raloxifene and olanzapine to provide a stable storage dosage form with reduced side effect. See Abstract and Claims and Examples. Thus, it would have been prima facie obvious to one of ordinary skill in the art to, by routine experimentation arriving at the claimed invention given the teachings in the Sun reference in view of the teaching in Turkyilmaz. This is because Turkyilmaz teaches an immediate release bilayer tablet useful for the delivery of olanzapine, this is because Turkyilmaz teaches an immediate release bilayer tablet that is stable for the delivery of an antipsychotic agent including olanzapine, and this is because Turkyilmaz teaches the use of the claimed excipients to obtain an immediate release bilayer tablet is known in the art. Response to Arguments Applicant’s arguments filed 08/19/2025 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion Applicant's submission of an information disclosure statement under 37 CFR 1.97(c) with the timing fee set forth in 37 CFR 1.17(p) on 08/19/2025 prompted the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 609.04(b). 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.
