Detailed Office Action
Notice of Pre-AIA or AIA Status
1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Objection to Abstract
2. The abstract of the disclosure is objected to because it is not adequately descriptive of the invention. A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b).
Applicant is reminded of the proper content of an abstract of the disclosure.
In chemical patent abstracts for compounds or compositions, the general nature of the compound or composition should be given as well as its use, e.g., “The compounds are of the class of alkyl benzene sulfonyl ureas, useful as oral anti-diabetics.” Exemplification of a species could be illustrative of members of the class. For processes, the type of reaction, reagents and process conditions should be stated, generally illustrated by a single example unless variations are necessary.
Indefiniteness Rejection
3. The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
4. Claims 1-8, 10, 13-21, 25, and 26 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.
Firstly, the method, as claimed, is confusing, because once the amino acid alkyl ester reacts with triphosgene, the resulting product will be an ester urea sans amino groups; therefore the name amino acid ester urea is imprecise and misleading.
Secondly, with respect to claims 1 and 17-19, the language, “the amino acid”, lacks strict antecedence.
Thirdly, with respect to claim 5, the language, “the alkyl ester” and “the alkyl ester hydrochloride”, lacks strict antecedence.
Fourthly, with respect to claim 19, the language, “at a rate of yield than 99%”, is not grammatically correct and cannot be clearly understood.
Comment with Respect to Most Relevant Prior Art
5. Claims 1-8, 10, 13-21, 25, and 26 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
6. The most relevant prior art is considered to be WO 2019/104163 A1 which discloses the production of PEU by reacting an amino acid based polyester with a urea forming reactant such as triphosgene. This method differs from the instant method, wherein an amino alkyl ester is reacted with triphosgene to produce an ester urea compound, which is subsequently reacted with a diol to form PEU.
