Office Action

§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 . 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 27 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. Claim 27: “a closed-loop process that allows reuse of a base solution” is new matter. There is no disclosure, discussion, or description of a “closed-loop process” in the original disclosure. 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 23-26 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. Claim 23: “said regenerated enolizable ketone and alcohol” lack antecedent basis in the claim “said released absorbed water” lacks antecedent basis in the claim Claim 25: “said released absorbed water” lacks antecedent basis in the claim. It is unclear how Claim 25 is related to Claim 24. Is the “a water-absorbed salting out solution” the same as the one recited in Claim 21 or is it a separate solution? There is no action in the “wherein” clause. Is the “a water-absorbed salting out solution” referring back to same named solution in Claim 21 or a separate solution? Is the “a desalinating process” referring to the process described in Claims 24 and 21 from which it depends or a separate desalinating process? Claim 26: Claim 26 recites “recycled regenerant solution” twice. It is unclear if these are the same solutions. It is unclear how a solution can be used in itself. It is unclear how “recycling a recycled regenerant solution” can be used in itself, i.e. “said recycled regenerant solution. If they are different solutions, then “said recycled regenerant solution” lacks antecedent basis in the claim. Allowable Subject Matter Claims 21 and 22 are allowed.
