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 . Claim Objections Claim 1 is objected to because of the following informalities: the bullet points “●” are not permitted and should be removed. The bulleted text should be separated by appropriate punctuation (e.g., semicolons or the like). Appropriate correction is required. Claims 6-11 are objected to under 37 CFR 1.75(c) as being in improper form because a multiple dependent claim should refer to other claims in the alternative only. See MPEP § 608.01(n). Accordingly, the claims 6-8 and 11 have not been further treated on the merits. 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 1-5 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 1, the claim does not end with a period “.”. Thus, the metes and bounds of the claim would have been unclear to one of ordinary skill in the art. Claims depending from claim 1 are rejected for reading upon an indefinite claim. Regarding claim 3, the parenthetical phrase(s) “(sulphadoxine and sulphamethoxypyridazine)” and/or “(dipeptidyl vinyl sulfones and peptidomimetic pyrimidine nitriles)” render(s) the claim indefinite because it is unclear whether the limitations within the parentheses are part of the claimed invention. See MPEP § 2173.05(d). Regarding claim 4, the parenthetical phrase(s) “(abexinostat…tubastatin A)” and/or “(MMA-E…and dolastatinol)”renders the claim indefinite because it is unclear whether the limitations within the parentheses are part of the claimed invention. See MPEP § 2173.05(d). Conclusion Claims 1-11 are pending. Claims 1-5 are rejected. Claims 6-11 are objected. No claims are allowed. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Miranda, Daniela, et al. "Novel endoperoxide-based transmission-blocking antimalarials with liver-and blood-schizontocidal activities." ACS medicinal chemistry letters 5.2 (2014): 108-112 (Miranda) is representative of prior art. Miranda teaches tetraoxane-primaquine hybrids having formula PNG media_image1.png 258 686 media_image1.png Greyscale . See Abstract. Miranda further teaches tetraoxane-primaquine hybrids 5-6, 8, 10, and 12 (Scheme 1). PNG media_image2.png 546 520 media_image2.png Greyscale Miranda does not teach or suggest a tetraoxane-primaquine hybrid wherein the linker is -OC(O)-. It would not have been obvious to modify a tetraoxane-primaquine hybrid of Miranda to arrive at an instantly claimed compound as prior art does not teach a suggest a structurally similar compound wherein the linker is -OC(O)-.
