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 .
Applicant’s amendments and remarks filed October 6, 2025 have been received and reviewed. Claims 13-29 are now pending in this application.
Claim Rejections - 35 USC § 112
Claims 13-29 are 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.
i) It is noted that R1 is now limited to C2-C12 alkyl groups, optionally substituted, to overcome the prior art rejections of the previous office action. The group “alkenyl (C1-C12)” should also be amended to have at least two carbons (C2-C12) because al alkenyl cannot be made up only one carbon. The smallest alkenyl is ethenyl.
ii) The term “(hetero)aryl,” as well as, “carboxyl (hetero) aryl” are still indefinite because it is not known how many atoms are present, how many and what kind of heteroatoms are involved, what size ring is intended and how many rings are present. It is unclear what the purpose of the parentheses represents, are groups, such as a carboxyl substituted heteroaryl intended? A clarification is still required.
iii) Claim 14 depends from claim 13 but includes compounds not embraced by claim 13. Thus, the compounds “(18),” “(25)” and “(49)” lack antecedent basis in claim 13. Claim 14 is improperly dependent from claim 13.
Thousands of compounds still on the compound of claim 13. Thus, a complete search of the entire genus could not be performed. The compound of formula (I) can be reduced to compounds wherein R1 is ethyl, R2 is H and R3 is H.
Below are exemplary prior art rejections of formula (I).
Claim Rejections - 35 USC § 102
The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
Claim 13 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Shin et al. (Chemistry Letters (1976), (10), 1063-6). The claim reads on the compounds depicted below. See Abstract.
