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 .
Status of the Application
Claims 1-12 are pending.
Election/Restrictions
Applicant's election without traverse of Group III, claims 7-10, directed to a process of making sucrose-6-carboxylate, and the species of acetoxy-tributyltin in the reply filed on 11/03/2025 is acknowledged. The election was made without traverse.
The requirement is therefore made FINAL.
Claims 1-6 and 11-12 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected invention, there being no allowable generic or linking claim.
Applicant is reminded that upon the cancellation of claims to a non-elected invention, the inventorship must be amended in compliance with 37 CFR 1.48(b) if one or more of the currently named inventors is no longer an inventor of at least one claim remaining in the application. Any amendment of inventorship must be accompanied by a request under 37 CFR 1.48(b) and by the fee required under 37 CFR 1.17(i).
Claims 7-10 are under current examination.
Claim Rejections - 35 USC § 112
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.
Claims 8-10 are rejected under 35 U.S.C. 112(b), as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention.
Claims 8-10 are indefinite as:
claim 8 is indefinite as the claim recites “temperature of 60---, preferably 70---pressure of 0.01kPa---, preferably 0.5kPa ---for 0.1min to 8h, preferably---”, which reflects use of broad and narrow limitations within the same claim. Thus, making scope of claim unclear. See MPEP 2173.05(c),(d).
claim 9 is indefinite as the claim recites at several instances broad and narrow limitations within the same claim “polar solvent---dimethylsulfoxide---, preferably N,N dimethylformamide---”. Thus, making scope of claim unclear.
Claim 10 is indefinite as the claim recites at several instances broad and narrow limitations within the same claim “temperature---, preferably---”. Thus, making scope of claim unclear.
Appropriate correction required.
Allowable subject Matter
Claim 7 is presently allowable subject matter over the prior art on record.
The following is an Examiner’s statement for indicating allowable subject matter:
Applicant’s process of making sucrose-6-carboxylate using mono-tin compound of formula I as a catalyst as in the instant claims is novel and unobvious over the prior art of record. None of the prior art of record disclose or teach applicant’s method of preparing sucrose-6-carboxylate using mono-tin compound of formula I as a catalyst as in the instant claims. The closest prior art, Micinski (US9073959 B2), teaches a process for making sucrose-6-carboxylate using organotin compound having distannoxane, different from formula I as a catalyst. Further, the cited prior art would not suggest nor motivate to a person of ordinary skill in the art to modify catalyst of the cited prior art to practice process as in the instant claim.
Conclusion
Claim 7 is allowed.
