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 . Election/Restrictions Applicant’s election of Group I, claims 1-4 and 7-23 in the reply filed on 1/5/26 is acknowledged. Because applicant did not distinctly and specifically point out the supposed errors in the restriction requirement, the election has been treated as an election without traverse (MPEP § 818.01(a)). Likewise, applicant’s election of the species Core 2+galactose (as depicted structurally in claim 23 – see also figure 9A herein) is acknowledged and claims 1-4, 7-17, and 23 read on this elected species. MPEP 803.02 III A notes that if the examiner determines that the elected species is allowable over the prior art, the examination of the Markush claim will be extended. If prior art is then found that anticipates or renders obvious the Markush claim with respect to a nonelected species, the Markush claim shall be rejected; claims to the nonelected species would still be held withdrawn from further consideration. The prior art search will not be extended unnecessarily to cover all nonelected species, and need not be extended beyond a proper Markush grouping. See subsection III.C.2, below, for additional guidance. It is noted that this elected species is free of the art. As such, the search and examination has been expanded beyond the elected species of the Markush group of claim 1 to include fucosylated glycans derived from cervical mucins. Claims 1-4 and 7-8 read on this additionally examined species. See below for art reading on this. As such, claims 18-22 are withdrawn and the portion of claims 1-4, 7-17, and 23 which does not read on the elected and additionally examined compounds above are withdrawn. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. Claim(s) 1-4 and 7-8 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Domino et al (Glycoconjugate Journal, vol. 26, no. 9, March 2009, pp 1125-1134). Domino discloses methods of administering exogenous mucins displaying α(1-2)fucosylated glycans (see page 1131, right column and table 2). The compositions administered were used to test a potential therapeutic treatment of yeast vaginitis where the mice were inoculated with C. albicans (a fungi) and tested to determine antifungal activity – see results on figure 4 showing the treated group had a lower fungal burden compared to the non-treated group. Domino states that their results showed that mucins can have an affect either positively or negatively in adhesion and/or proliferation of C. albicans (see right column on page 1131), thus meeting the present limitations in claim 3 wherein the treatment can reduce the fungus’s surface adhesion. These mucin glycans would meet the limitations of those comprising at least fucose and galactose (see table 2 therein). Allowable Subject Matter Claim 23 is 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. Claim Objections Claims 1-4 and 7-17 are objected to for containing non-elected subject matter.
