Office Action

§102
DETAILED ACTION The present application is being examined under the pre-AIA first to invent provisions. Claim Rejections - 35 USC § 102 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. Claims 1-3, 7-13, and 28 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Narula et al. (US 2018/0187091). Regarding claim 1 and 28, Narula et al. teaches a catalyst composition comprising a zeolite phase, particularly ZSM-5, and at least one metal dispersed through the zeolite phase, where suitable metals include copper, iron, zinc, titanium, vanadium, cadmium, and lanthanides ([0027], [0029], [0036]). The use of copper and iron loaded ZSM-5 is specifically taught ([0054]). The reference teaches that the metals are incorporated homogeneously into the composition ([0046]) and does not describe agglomerations of metal present. Therefore, it is considered there are no agglomerations. Refer also to [0050], [0051], [0055]. Regarding claims 2-3, the metal-zeolite phase composition taught by Narula et al. comprises dealuminated zeolite phase ZSM-5 ([0026], [0027]). Regarding claims 7-9, as discussed above, Narula et al. do not describe agglomerations of metal present. Therefore, it is considered there are no agglomerations. Regarding claims 10-13, the product-by-process limitations of the metal-zeolite composition are noted. It is considered that while the product of the reference is made by a different process, the product made and disclosed is the same as being claimed. See “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 USPQ 964,966). Once the Examiner provides a rationale tending to show that the claimed product appears to be the same or similar to that of the prior art, although produced by a different process, the burden shifts to applicant to come forward with evidence establishing an unobvious different between the claimed product and the prior art product (In re Marosi, 710 F.2d 798, 802,218 USPQ 289, 292 (Fed. Cir. 1983). See MPEP 2113. Response to Arguments Applicant’s arguments with respect to claims 1-3, 7-13, and 28 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
