Office Action

§102 §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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 2026 May 15 has been entered. Newly amended claims 1-3, 5-9, and 13-16 are examined on the merits. Claim Objections Claims 2, 3, and 5 are objected to because of the following informalities: In claims 2, 3, and 5, the language “claim 1, and a pharmaceutically acceptable salt” should be --claim 1, or a pharmaceutically acceptable salt— because a pharmaceutically acceptable salt, hydrate, or solvent mixture thereof are each alternative forms of a compound of claim 1; in claim 2, the language “compounds have the following structures of formula (I-3)” does not agree with the preamble of the claim, which is “The compound of claim 1”; and in claim 3, the language “compounds have the following structures of formula (I-6)” does not agree with the preamble of the claim, which is “The compound of claim 1”. In each claim the specified language should be stated in singular tense. Application of this idea to claim 2 could result in changing the language “compounds have the following structures of formula (I-3)” to --compound having the following structure of formula (I-3)--. Application of this idea to claim 3 could result in changing the language “compounds have the following structures of formula (I-6)” to --compound having the following structure of formula (I-6)--. In claim 3, the language “wherein each group is defined as in claim 1” is extraneous because variable R2 is assumed to have the same limitations as in claim 1 unless it is further limited. Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claim 2 is rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. In the specification, formula (I-3) is the following structural formula. When these two formulae are compared, formula (I-3) of the specification does not provide support for the claimed formula (I-3) due to the substituents attached to the 3-position of the β-lactam ring. In the specification formula (I-3), a =CH-R group is attached to the 3-position. In the claim 2 formula (I-3), the 3-position is substituted with -OR and -CH2OR group moieties. Due to the substitution pattern being different in each formula, claim 2 contains new matter.

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 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by PAGILIARIN (WO 2013017548, published 2023 February 7). Pagliarin describes compound 6 (page 11), a compound in which the following examined definitions apply: R2 is OMe; R3 is H; R4 is O-C(O)-Me in which R is methyl. PNG media_image3.png 230 672 media_image3.png Greyscale Conclusion Claims 1 and 2 are not allowed. Claims 13-16 are allowable. Claims 6-9 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. The following is a statement of reasons for the indication of allowable subject matter: PAGILIARIN (WO 2013017548, published 2023 February 7) describes compound 6 (page 11), a compound in which the following examined definitions apply: R2 is OMe; R3 is H; R4 is O-C(O)-Me in which R is methyl. This compound does not anticipate or render obvious a compound of claims 2, 3, 5, or 13 because a combination of variables R3 and R4 is [H, O-C(O)-Me] is not permitted in these claims.
