Double Patenting
4. The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.

Claim Rejections - 35 USC § 103
31. 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 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.
32. Claims 1-3, 5-7, and 10-11 are rejected under 35 U.S.C. 103 as being unpatentable over Lin et. al., Cubic Pm3n mesoporous aluminosilicates assembled from zeolite seeds as strong acidic catalysts. (Lin) in view of Vidjayacoumar et al. (WO 2020016709 A1) (Vidjayacoumar), taken in view of evidence by Wu, L. et. al., Hierarchically structured porous materials: synthesis strategies and applications in energy storage. (Wu).
33. Regarding claims 1, 3 and 5, Lin teaches cubic Pm3n mesoporous aluminosilicates with 3D interconnected pore structures, were assembled from Al-incorporating zeolite seeds (i.e. a modified zeolite) (Lin, Abstract) to exhibit high catalytic activities (Lin, p. 3182, right column, last paragraph)
wherein the cubic Pm3n mesoporous silica assemblies (Lin, p. 3183, right column, section 2.3) are designated as Al–ZSBA-1 (i.e. a modified zeolite) (Lin, p. 3183, right column, section 2.3)
wherein the Al–ZSBA-1 samples contain small numbers of micropores (Lin, p. 3185, left column, first paragraph), that according to the International Union of Pure and Applied Chemistry (IUPAC) microporous materials have pore sizes < 2 nm (Wu, 1668, left column, paragraph 1), which encompasses the claimed range.
Lin further teaches ZSM-5 seeds for the micropores comprise silicate (i.e. comprise at least silicon atoms and oxygen atoms) (Lin, p. 3183, right column, section 2.2).
Lin further teaches that the Al–ZSBA-1 (i.e. a modified zeolite) are mesoporous (i.e. a plurality of mesoporous) (Lin, p. 3185, left column, first paragraph), that according to the International Union of Pure and Applied Chemistry (IUPAC) mesoporous materials have pore sizes of 2-50 nm (Wu, 1668, left column, paragraph 1), which encompasses the claimed range.
Lin further teaches the Al–ZSBA-1 (a modified zeolite) samples exhibit cubic Pm-3n symmetry (Lin, p. 3184, right column, Results and Discussion).
However, Lin does not teach a plurality of titanium hydride moieties each bonded to at least two bridging oxygen atoms, wherein a titanium atom of the titanium hydride is bonded to the bridging oxygen atom, and wherein the bridging oxygen atom bridges the titanium atom of the titanium hydride moiety and a silicon atom of the microporous framework.
With respect to the difference, Vidjayacoumar teaches a metal hydride catalyst comprising a support having [(ºSi-0-)xMH.sub.y][SiH.sub.z] on the surface of the support (i.e. a modified zeolite) (Vidjayacoumar, [0010]).
wherein the support is a microporous silicate or zeolite support (i.e. a microporous framework), that according to the International Union of Pure and Applied Chemistry (IUPAC) microporous materials have pore sizes < 2 nm (Wu, 1668, left column, paragraph 1)
Vidjayacoumar further teaches the metal hydride catalyst is a titanium hydride (i.e. a plurality of titanium hydride moieties) (Vidjayacoumar, Title)
wherein the most probable species are mono or bis hydride (i.e. the plurality of titanium hydride moieties) (Vidjayacoumar, [0058]) with two hydrogens and two bridging oxygen atoms attached (Vidjayacoumar, p. 20, Fig. 1 (Stage 2)), see annotated Fig. 1(Stage 2) below,
wherein a titanium atom of the titanium hydride is bonded to the at least two bridging oxygen atoms, and wherein the at least two bridging oxygen atoms bridge the titanium atom a silicon atom (Vidjayacoumar, p. 20, Fig. 1 (Stage 2)) of the microporous silicate or zeolite (i.e. a microporous framework) (Vidjayacoumar, [0010]).

Annotated Fig. 1(Stage 2)
Vidjayacoumar expressly teaches existing processes for ammonia production are energy intensive (Vidjayacoumar, [0003]) wherein the metal hydride catalyst comprising the support produces ammonia in the presence of nitrogen and hydrogen (Vidjayacoumar, [0014]), thus providing a more efficient production of ammonia from nitrogen (Vidjayacoumar, [0002]) that operates at lower temperatures and pressures than existing catalyst used in the production of ammonia (Vidjayacoumar, [0008]).
Lin and Vidjayacoumar are analogous art as they are all drawn to zeolite catalysts.
In light of the motivation for the incorporation of titanium hydrides on a microporous zeolite catalyst support as disclosed by Vidjayacoumar, it therefore would have been obvious to one of ordinary skill in the art to include the titanium hydride catalyst to the microporous framework of Al–ZSBA-1 (a modified zeolite) of Lin, in order to achieve a catalyst with a more efficient production of ammonia from nitrogen and is able to operate at lower temperatures and pressures than existing catalyst used in the production of ammonia, and thereby arrive at the claimed invention.
34. Regarding claim 2, Vidjayacoumar further teaches the metal hydride catalyst (i.e. modified zeolite) is a titanium hydride comprising contacting nitrogen and hydrogen to react to produce ammonia (Vidjayacoumar, [0014])
wherein among the Ti-Hx formed (i.e. the plurality of titanium hydride moieties) some specific hydrides are highly active (Vidjayacoumar, [0060])
wherein 200 mg of the metal hydride catalyst (i.e. modified zeolite) was used for the reaction with an active Ti content (i.e. titanium hydride) of 0.0539 or 0.0493 mmol (Vidjayacoumar, [0066]) to achieve the synthesis of catalytic amounts of ammonia to reach a high catalyst efficiency measured as a TON (turnover number) (Vidjayacoumar, [0067]).
After conversion, the amount of active titanium would necessarily be 0.2695 (0.0539 mmol Ti / 0.200 g of metal hydride catalyst) and 0.2469 mmol/g (0.0493 mmol / 0.200 g), which falls within the recited range.
Given that Vidjayacoumar teaches using 0.2695 and 0.2469 mmol/g in the formation of catalytic amounts of ammonia (Vidjayacoumar, [0067]), it is clear using the amount of titanium in the catalyst would achieve a desirable reactivity to produce ammonia.
In light of using the amount of the titanium in the catalyst, as disclosed by Vidjayacoumar, it therefore would have been obvious to one of ordinary skill in the art to use the amount of titanium, i.e., 0.2695 and 0.2469 mmol/g in the microporous framework of Al–ZSBA-1 (i.e. a modified zeolite) of Lin, in order to achieve a desirable reactivity to produce ammonia via highly active Ti-Hx moieties (i.e. the plurality of titanium hydride moieties), the synthesis of catalytic amounts of ammonia to reach a high catalyst efficiency measured as a TON (turnover number), and thereby arrive at the claimed invention.
35. Regarding claims 6-7, Lin further teaches the Al–ZSBA-1 (i.e. a modified zeolite) are designated xAl–ZSBA-1 where x is the Al/Si molar percentage in the synthesis solution (i.e. further comprises aluminum atoms) (Lin, p. 3183, right column, section 2.3)
wherein the 1Al–ZSBA-1, 3Al–ZSBA-1, and 5Al–ZSBA-1 modified zeolites have a Si/Al molar ratio of 100 (i.e. 100/1), 33.3 (i.e. 100/3), and 20 (i.e. 100/5) (Lin, p. 3186, Table 3), which fall within the recited range.
36. Regarding claim 10, Lin further teaches the Al–ZSBA-1 (i.e. modified zeolite) samples have surface areas in the range of 600–800 m2 g−1) (Lin, p. 3185, left column, first paragraph),
wherein 1Al–ZSBA-1, 3Al–ZSBA-1, and 5Al–ZSBA-1 modified zeolites have surface areas of 759, 677, and 652 m2 g−1 (Lin, p. 3186, Table 3), which fall within the recited range.
37. Regarding claim 11, Lin further teaches the 1Al–ZSBA-1, 3Al–ZSBA-1, 5Al–ZSBA-1 modified zeolites have total pore volumes (Vtotal) of 0.86, 0.70, and 0.66 cm3/g, which fall within the recited range (Lin, p. 3186, Table 3).
Allowable Subject Matter
38. Claims 8-9 and 12-13 objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
39. Claims 8-9 and 12-13 would be allowable if rewritten 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 and to include all of the limitations of the base claim and any intervening claims.
40. While Lin and Vidjayacoumar teach the limitations of claim 1, Lin and Vidjayacoumar do not disclose or suggest the limitations of claim 8-9. Specifically, Lin teaches that ZSM-5 seeds were used as the silica and aluminum sources (Lin, p. 3183, right column, section 2.3)
wherein ZSM-5 is an MFI-type framework zeolite and not a USY zeolite.
41. While Lin and Vidjayacoumar teach the limitations of claim 1, Lin and Vidjayacoumar do not disclose or suggest the limitations of claim 12-13. Specifically, Vidjayacoumar discloses the support (i.e. modified zeolite) is silica and silica hydride (i.e. silica hydride moieties) (Vidjayacoumar, [0043]).
However, Vidjayacoumar does not disclose or suggest the silica hydride moieties each bonded to bridging oxygen atoms. Further, Vidjayacoumar Fig. 1 - (Stage 2) discloses the silica hydride moieties are not bonded to the bridging oxygens atom, which is outside of scope of the claims.
Even if Vidjayacoumar was to combine with Lin, there would not be proper motivation to combine. Specifically, while Vidjayacoumar discloses the support (i.e. modified zeolite) is silica and silica hydride (i.e. silica hydride moieties). There is no evidence that a modified zeolite with a microporous framework comprising silica hydride moieties in Vidjayacoumar would achieve a substantially identical advantageous property.
