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 § 102 and 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim(s) 30 is/are rejected under 35 U.S.C. 102(a)(1) as anticipated by or, in the alternative, under 35 U.S.C. 103 as obvious over Navard et al. “Etude Thermique de la N-methylmorpholine N0oxyde et de sa complexation avec l’eau”.
Claim 30 recites a N-methylmorpholine N-oxide hydrate crystal obtained by the method of claim 18. Claim 18 recites the hydrate crystals are 2NMMO-5H2O. The recitation of the crystals being obtained by the method of claim 18 is a recitation of how the crystals are made and renders the claim a product by process claim. “[E]ven though product-by-process claims are limited by and defined by the process, determination of patentability is based on the product itself. The patentability of a product does not depend on its method of production. If the product in the product-by-process claim is the same as or obvious from a product of the prior art, the claim is unpatentable even though the prior product was made by a different process.” In re Thorpe, 227 USDQ 964 (1985). In this case, the prior art to Navard teaches a NMMO hydrate crystal of 2NMMO-5H2O. The structure then of the crystal is known in the art as demonstrated by Navard and how the crystal is obtained is a structural alternative to the process of claim 18.
Allowable Subject Matter
Claims 18-29 are allowed.
The following is an examiner’s statement of reasons for allowance:
The closest prior art of record to Feng et al. CN 101280476 teaches a purification method of NMMO comprising the steps of performing cooling crystallization to a lyocell fiber coagulation bath, where the NMMO liquid is sent through an evaporator at a temperature of 58-62 degrees C and after naturally cooling, crystallizing. Feng does not teach cooling the bath to between 25-40 degrees C or that the hydrate crystal is 2NMMO-5H2O nor would it have been obvious to one of ordinary skill in the art to modify the prior art to arrive at the claimed invention.
The additional claims are allowable as depending from claim 18.
Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.”
