Office Action

§102
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 . Response to Arguments Applicant’s arguments, see Page 1, filed 10/20/2025, with respect to the rejection(s) of claim(s) 1-9 and 20 under Douguet et al. (US 20080086907) have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of Yamamoto et al. Boron-10 carriers for NCT. A new synthetic method via condensation with aldehydes having boronic moiety, October 1989, Pages 7191-7194. Yamamoto teaches boron-10 nucleoside derivates compounds that reads to the compounds of claimed invention. Applicant has added claims 30-31. No new matter was added. Claims 1-22 and 30-31 are now pending. Claims 1-22 and 30-31 is now evaluated on its merits. 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 1-6, 8-9 and 20 are rejected under 35 U.S.C. 102 (a)(1) as being anticipated by Yamamoto et al. Boron-10 carriers for NCT. A new synthetic method via condensation with aldehydes having boronic moiety, October 1989, Pages 7191-7194. Regarding claims 1-6, 8-9 and 20, Yamamoto teaches compounds that are boron- 10 containing nucleoside derivatives for neutron capture therapy. Of the compounds Yamamoto teaches PNG media_image1.png 169 158 media_image1.png Greyscale PNG media_image2.png 122 164 media_image2.png Greyscale and PNG media_image3.png 214 185 media_image3.png Greyscale PNG media_image4.png 69 163 media_image4.png Greyscale and an acceptable carrier (relevant to claims 1-6, 8-9 and 20) (Fig.1 and Fig.2). The above compounds read to claimed invention of Formula 102 wherein D being a pyrimidine prodrug moiety, at least one R1-R5 is B(ORa)ORb, Rc or Rd is hydrogen and the other is a substituted alkyl. Allowable Subject Matter Claims 7, 10-19 and 21-22 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Claims 30-31 are free of the arts. Closest prior art is of Douguet et al. (US Patent No. 20080096907) which teaches PNG media_image5.png 92 149 media_image5.png Greyscale PNG media_image6.png 386 274 media_image6.png Greyscale (para. 0038). The teachings of Douguet differs from claimed invention of the structure of D. 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).
