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 .
Detailed Action
This office action is a response to applicant’s communication submitted February 2, 2026, wherein a response is made to the previous restriction requirement. This application is a national sage application of PCT/US2022/026225, filed April 25, 2022, which claims benefit of provisional applications 63/264011, filed November 12, 2021, and 63/178731, filed April 23, 2021.
Claims 1, 3, 4, 8-21, 24, 25, and 28 are pending in this application.
Election/Restrictions
Applicant’s provisional election without traverse of group I, claims 1, 3, and 4, drawn to a saccharide compound, filed February 2, 2026, is acknowledged.
Claims 8-21, 24, 25, and 28 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim.
Claims 1, 3, and 4 are pending in this application and examined on the merits herein.
Claim Rejections - 35 USC § 112
Claim 4 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. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claim 4 recites the broad recitation “wherein G is a sugar moiety,” and the claim also recites “optionally wherein G is a monosaccharide moiety, a disaccharide moiety, a trisaccharide moiety, or a tetrasaccharide moiety,” which is the narrower statement of the range/limitation. The claim is considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims.
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, 3, and 4 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Yamaguchi et al. (NPL Reference 23 included with 10/30/2025 PTO-1449)
Yamaguchi et al. discloses mannose-6-phosphate oligosaccharide compounds such as 15B (p. 12474 scheme 2 compound 15b) which falls within the scope of present claims 1, 3, and 4 when G is a tetrasaccharide. Therefore Yamaguchi et al. anticipates the claimed invention.
