Claims 1-8 are objected to because of the following informalities: Claim 1 is objected to because the claim should cite “a loading weight range of 1% up to10%”. Claim 5 is objected to because the claim should cite “the loading weight range is 2.5% up to10%”. Claim 6 is objected to because the claim should cite “the loading weight range is 2.5% up to 7.5%.” Appropriate correction is required.
Claim Rejections - 35 USC § 112
Claims 1-8 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 1 is rejected because it is unclear how nickel powder can comprise nickel-filamentary branching structures because nickel powder is known to consist of fine, discrete particles which are granular (spherical) while nickel fiber refers to long, thin strands that offer 3D networks forming intricate and interconnected strands. Claim Rejections - 35 USC § 103
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.
Claim(s) 1-8 are rejected under 35 U.S.C. 103 as being unpatentable over by Zhu et al. “Effects of fibrous nickel additives on the electrochemical properties of LiFePO4 cathode for lithium-ion battery” in view of Ferment et al. (US 6,143,445). Zhu et al. teaches in the abstract that highly conductive nickel additive can enhance the electronic conductivity of LiFePO4 when the fiber content is present at 10 wt%. Zhu et al. teaches on pages 10601-10602, that the morphologies of nickel fibers [branching] are shown in figure 3(a). Zhu et al. teaches adding nickel fibers to a cathode material comprising LiFePO4 with different fiber content as shown in Table 1, teaching adding a nickel-fiber loading of 4% [teaching claims 3-4] and 8% to the active material. Zhu et al. teaches on page 10598, that it has been found that porous nickel fibers with low aspect ratio is conducted additives could improve the electrochemical performance of LiFePO4 cathodes. Figure 3 (a) shows nickel fibers having a length of 2-5 μm and a diameter of 0.1-0.5 μm. This kind of fiber has a porous structure with specific surface area of 25.8 m2/g, could be in favor of the combination between LiFePO4, additives and current collector surfaces and enhance the electronic conduction ability of the whole LiFePO4 electrode during charge/discharge process. Zhu et al. discloses the claimed invention teaching a battery cathode comprising an active base material comprising lithium iron phosphate and comprising a conductive nickel-filamentary branching structure in the loading weight range claimed but does not teach further adding another additive comprising a metal such as aluminum or nickel coated precision chopped fiber comprising 5 wt% out of the total 10 wt% of additives. Ferment et al. teaches in claim 1, a positive electrode comprising a composite electrode material comprising an active material, a carbon powder, a binder and chopped up electrically conductive metallized fibers. Ferment et al. teaches in column 2, lines 59-67, that the electroconductive fibers may be carbon fibers, plastic fibers, or other fibers, which have been metallized in any well-known manner such as by spraying, sputtering, vacuum deposition, dip coating, electroplating or electroless metal plating and the metal coating may be of any suitable materials such as aluminum [teaching claim 8, aluminum-coated fibers], nickel [teaching claim 7, nickel-coated fibers] or other materials selected to be compatible with the components of the battery or device. Ferment et al. teaches in column 3, lines 1-4, that the fibers after coating with metal or chopped into small pieces and then mixed into an electrode slurry which includes the active material, the carbon powder and the binder. Ferment et al. teaches in column 3 lines 17-29, that the presence of the chopped metallized fibers markedly improves the electrical conductivity of the electrode. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to include aluminum coated carbon fibers or nickel coated carbon fibers to the cathode material taught by Zhu et al. because Ferment et al. teaches that the presence of the chopped metallized fibers markedly improves the electrical conductivity of the electrode. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention as claimed in claims 2 and 4-6 to use 5 wt% of the metal-coated chopped fibers when Zhu et al. teaches using 4-5 wt% of the conductive nickel-filamentary branching structures and to use 2.5 wt% of the conductive nickel-filamentary branching structures and to use 2.5 wt% as claimed in claim 3, since it has been held that where general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. In re Aller, 105 USPQ 233.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to use to use 5 wt% of the metal-coated chopped fibers when Zhu et al. teaches using 4-5 wt% of the conductive nickel-filamentary branching structures and to use 2.5 wt% of the conductive nickel-filamentary branching structures and to use 2.5 wt% as claimed in claim 3, since it has been held that discovering an optimum value of a result effective variable involves only routine skill in the art. In re Boesch, 617 F.2d 272, 205 USPQ 215 (CCPA 1980). Double Patenting
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.
The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission.

Claims 1-8 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-8 of copending Application No. 18/079,806 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because Application No.18/079,806 claims in claim 1, a battery cathode with enhanced electrical conductivity for use in a battery, the battery cathode comprising: an active base cathode material comprising lithium iron phosphate; and a 1st additive comprising nickel-coated precision chopped fibers and a claims in claim 2, that further comprises a 2nd additive comprising conductive nickel filamentary branching structures comprising branching nickel powder which is also dispersed within the active base cathode material in a loading weight range 1% of up to 15% of the active base cathode materials. Application No.18/079,806 claims in claim 4, wherein the first additive comprises nickel-coated carbon fibers. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
Claims 1-8 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-5 of copending Application No. 18/079,814 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because Application No.18/079,814 claims in claim 1, a battery cathode with enhanced electrical conductivity for use in a battery, the battery cathode comprising: an active base cathode material comprising lithium iron phosphate; a 1st additive comprising metal-coated precision chopped fibers and claims in claim 2, further adding a 2nd additive comprising conductive nickel filamentary branching structures comprising branching nickel which is also dispersed within the active base cathode material in a loading weight range 1% of up to 10% of the active base cathode materials. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
Claims 1-8 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-8 of copending Application No.18/079,821 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because Application No.18/079,821 claims in claim 1, a battery cathode with enhanced electrical conductivity for use in a battery, the battery cathode comprising: an active base cathode material comprising lithium iron phosphate; and a 1st additive and a 2nd additive comprising conductive nickel filamentary branching structures comprising nanostrands which is also dispersed within the active base cathode material in a loading weight range 1% of up to 10% of the active base cathode materials. Application No.18/079,821, claims in claim 3, wherein the 2nd additive of nanostrands comprise 2.5% and claims in claim 4 wherein the nanostrands comprise 5% of the loading weight of the active base battery cathode material. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
