Office Action

§102
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 . Status of the Claims Claims 1-10, 13-20 and 22-23 are pending. Claims 1-10, 13-18 and 23 are withdrawn. Claims 19-20 and 22 are rejected. Response to Amendment/Arguments The amendment filed September 9, 2025 is compliant with the requirements of 37 CFR 1.121(c), accordingly the amendment has been entered. Applicant’s arguments have been fully considered and are addressed below: 35 USC § 102 Rejection The anticipation rejection of claims 19-20 and 22 over Burrow et al. US 4,322,429A, as evidenced by CAS Registry No. 82361-16-8, has been overcome by the narrowing the scope of R2 to exclude aryl groups; thereby circumventing Burrow’s compounds of the formula PNG media_image1.png 247 356 media_image1.png Greyscale , such as PNG media_image2.png 217 448 media_image2.png Greyscale , wherein Burrow’s R2 is aryl-substituted isoxazole, wherein the aryl corresponds to instant R2. Election/Restrictions Examination of the elected invention was extended to non-elected species in accordance with the MPEP 803.02. The scope of formula (IV), PNG media_image3.png 139 313 media_image3.png Greyscale , wherein Z4, Z5 and Z6 are CH or C-R27, and R23, R24 and R27 are selected from hydrogen, was found unpatentable over the prior art. Since art was found on a nonelected species, subject matter not embraced by the elected embodiment or the above-identified non-elected subgenus is therefore withdrawn from further consideration. Claims 1-10, 13-18 and 23 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Applicant is reminded that upon the cancellation of claims to a non-elected invention, the inventorship must be amended in compliance with 37 CFR 1.48(b) if one or more of the currently named inventors is no longer an inventor of at least one claim remaining in the application. Any amendment of inventorship must be accompanied by a request under 37 CFR 1.48(b) and by the fee required under 37 CFR 1.17(i). Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 19-20 and 22 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Miyake et al. J. Pest. Sci, 2013, 38, 96-104. Miyake dissolved compound 44 in DMSO (2,500 mg/L) for pesticidal activity testing. See, e.g., p. 97, p. 101 (section 2) and Table 2. PNG media_image4.png 291 205 media_image4.png Greyscale This disclosure anticipates the compound of Formula IV, PNG media_image5.png 534 1148 media_image5.png Greyscale , wherein Y2 is O, W2 is N, Z4, Z5 and Z6 are CH, R22 is methyl (unsubstituted alkyl), R23 and R24 are H, as embraced by claim 19. The DMSO solution comprising the compound anticipates the composition of claim 20, since DMSO is a well-known pharmaceutically acceptable excipient, according to Official Notice. The DMSO solution also anticipates the composition of claim 22, requiring the compound be present in “an amount effective” for treating one of the claimed diseases. According to the specification: “an ‘effective amount’ of a compound of the present technology refers to an amount of the compound that alleviates, in whole or in part, symptoms associated with a disorder or disease, or slows or halts of further progression or worsening of those symptoms, or prevents or provides prophylaxis for the disease or disorder in a subject at risk for developing the disease or disorder.” Para. 98. The specification further explains that “[a] therapeutically effective amount of a compound of the present technology may vary depending upon the route of administration and dosage form. Effective amounts of such compounds typically fall in the range of about 0.01 up to about 100 mg/kg/day…” Para. 114. Since the 2,500 mg of the compound is present in 1L of DMSO, this solution would provide a PHOSITA with ample compound (i.e., effective amounts) for treating the claimed diseases. Allowable Subject Matter The elected species PNG media_image6.png 229 474 media_image6.png Greyscale is allowable over the prior art. The closest art was discussed on pp. 4-5 of the Office Action mailed June 11, 2025. Conclusion Claims 19-22 are rejected. 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 extension fee 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 date of this final action.
