In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 5 and 14-15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Li as provided for claim 1 above. Regarding Claim 5, Li discloses anode-solid electrolyte sub-assembly of claim 1, wherein the mixed ionic-electronic conductor structure has a porosity of about 60 percent or greater [Li 0010 Figs. 6B-6C show the volumetric capacity and gravimetric capacity for various porosities and evidence each are higher for porosities greater that 60%. Thus, Li obviates the claimed range. Per MPEP 2144.05, in the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists.], the mixed ionic-electronic conductor structure has an average pore size of about 5 nanometers to about 200 nanometers [Li 0163, 0195, 0199, 0216, 231-0232, claim 7 Li teaches less than 300 nm throughout, which obviates the claimed range. Per MPEP 2144.05, in the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists. Further, Li provides examples of 100 nm [Li 0195, 0199] and 30 nm, 68 nm, 60 nm, 160 nm [Li 0231-0234], which anticipate the claimed range.] and the mixed ionic-electronic conductor structure has a thickness of about 1 micrometer to about 100 micrometers [Li 0191, 0261, claim 8, Li teaches h as the thickness of the structure is 10 to 100 um [Li 0261], which overlaps and obviates the claimed range. Further, Li provide examples of 20 um [Li 0191], which anticipates the range. Per MPEP 2144.05, in the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists.] It would have been obvious to one of ordinary skill in the art before the effective filing date to select the claimed ranges from Li’s teaching as described above. Regarding Claim 14, Li discloses the anode-solid electrolyte sub-assembly of claim 1. Li does not explicitly teach wherein the interlayer has an average pore size of about 0.1 nanometer to about 100 nanometers; however, Li’s interlayer embodiments as described in claim 1 would be within the walls 1200 of MIEC 1110 [Li 0163]. Li teaches the walls are 1 nm to 30 nm [Li 0163]. Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date to provide pores in the interlayer within walls 1200 than are smaller than the thickness of the walls, which would require pores less than 30 nm, for the predictable result of a pore sized to accommodate lithium movement within the porous region of Li’s structure [Li 0156] to reduce the formation of dead lithium and/or provide spatially uniform transport of the alkali metal 1300/1310/1320/1330/1340 [LI 0165]. Thus, Li’s structure obviates the claimed range of average pore size. Per MPEP 2144.05, in the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists. Regarding Claim 15, Li discloses the anode-solid electrolyte sub-assembly of claim 1 wherein the plurality of open pores of the mixed ionic-electronic conductor structure has an average pore size [Li 0179, 0194-0195, 0199, and throughout, Li teaches less than 300 nm [0179] and further teaches examples where the pore size is 100 nm [0194-0195, 0199, and throughout]. Li does not explicitly teach this pore size is greater than an average pore size of the interlayer; however, Li’s interlayer embodiments as described in claim 1 would be within the walls 1200 of MIEC 1110 [Li 0163]. Li teaches the walls are 1 nm to 30 nm [Li 0163] and provides examples where the wall is 10 nm [LI 0199]; thus, it would have been obvious to one of ordinary skill in the art before the effective filing date to provide pores in the interlayer within walls 1200 which are smaller than the open pores of the MIEC 1110. Claim(s) 8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Li, as provided for claim 1 above, in further view of Lee et al. [US20200136177A1], hereafter Lee. Regarding claim 8, Li discloses the anode-solid electrolyte sub-assembly of claim 1, wherein the carbon anode active material comprises an amorphous carbon [Li 0183, 0220, and throughout] but is silent to wherein the amorphous carbon is carbon black, acetylene black, furnace black, Ketjen black, graphene, carbon nanotube, carbon nanofiber, or a combination thereof. Lee teaches that amorphous carbons for anode materials such as carbon black, acetylene black, furnace black, ketjen black, graphene, or any suitable amorphous carbon [Lee 0083-0084]. From Lee’s teachings, it would be understood that any of the amorphous carbons recited would be considered art recognized as suitable for use for an anode material. See MPEP 2144.06. It would have been obvious to one of ordinary skill in the art before the effective filing date to select any of Lee’s recited amorphous carbons as the amorphous carbon in Li’s MIEC for the predictable result of an amorphous carbon suitable for an anode material [Li 0183, 0220; Lee 0083-0084]. Claim(s) 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over De Souza as provided for claim 1 above. Regarding Claim 14, De Souza discloses the anode-solid electrolyte sub-assembly of claim 1, wherein the interlayer has an average pore size of about 0.1 nanometer to about 100 nanometers [De Souza 0048 De Souza teaches the pore size in the interlayer 16 has an average pore opening of less than 3nm [De Souza 0048], which obviates the claimed range. Per MPEP 2144.05, in the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists. For purpose of compact prosecution, alternative rejection of Claim 14: Claim(s) 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Li, as provided for claim 1 above, in further view of De Souza et al [US20200014058A1, as provided on the IDS dated 8/8/2024], hereafter De Souza. Regarding Claim 14, Li discloses the anode-solid electrolyte sub-assembly of claim 1. Li does not explicitly teach wherein the interlayer has an average pore size of about 0.1 nanometer to about 100 nanometers. De Souza teaches an interlayer disposed on a mixed ionic-electronic conductor structure and opposite the anode current collector [De Souza 0033-0058, 0075-0079 and throughout, Figs. 1-2, 7A, 9A-9C, PR1 (layer 17) as the interlayer on MIEC PR2 (layer 16) opposite current collector 10 and or plated lithium within 17(PR1)]and the mixed ionic electronic conductor structure with a MIEC material [De Souza 0033-0058, 0075-0079 and throughout, Figs. 1-2, 7A, 9A-9C, porous layer 16, PR2 as the MIEC]. De Souza further teaches the pore size in the interlayer 16 has an average pore opening of less than 3nm [De Souza 0048], which obviates the claimed range. Per MPEP 2144.05, in the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists. It would have been obvious to one of ordinary skill in the art before the effective filing date to combine De Souza’s teaching about pore size with Li’s anode sub assembly for the predictable result of a pore sized to accommodate lithium movement [De Souza 0036] within the porous region of Li’s structure [Li 0156] to reduce the formation of dead lithium and/or provide spatially uniform transport of the alkali metal 1300/1310/1320/1330/1340 [LI 0165].
