9. The rejection of Claims 6 and 7 under 35 U.S.C. 103 as being unpatentable over Nobuhiro et al. (JP 2013073924), in view of Zhamu et al. (U.S. Pub. US 2018/0175433), has been overcome based on the amendments to the Claims and the arguments presented on pages 5-7 of the Remarks dated April 28, 2026.
10. The rejection of Claim 10 under 35 U.S.C. 103 as being unpatentable over Nobuhiro et al. (JP 2013073924), in view of Son et al. (U.S. Pub. US 2016/0181603), has been overcome based on the amendments to the Claims and the arguments presented on pages 5-7 of the Remarks dated April 28, 2026.
11. The rejection of Claims 12-16 under 35 U.S.C. 103 as being unpatentable over Nobuhiro et al. (JP 2013073924), in view of Kim et al. (U.S. Pub. US 2018/0040875), has been overcome based on the amendments to the Claims and the arguments presented on pages 5-7 of the Remarks dated April 28, 2026.
12. Claim 2 is rejected under 35 U.S.C. 103 as being unpatentable over Xu et al. (CN 112151777 A), as applied to Claims 1, 3, 4, 9 and 12-16 above, and in further view of Liu et al. (US 2021/0184209 A1).
With regard to Claim 2, Xu et al. disclose the anode plate in paragraph 7 above, including the lithium-precipitation inhibiting layer containing lithium phosphate, but do not specifically disclose wherein the lithium-precipitation inhibiting layer contains at least one of the following lithium-precipitation inhibiting materials: LiFePO4, LiCoPO4, LiNiPO4, and LiMnPO4.
Liu et al. disclose a lithium ion rechargeable battery having a positive electrode material and a coating layer (considered a lithium-precipitation inhibiting layer) on the electrode material (paragraph 0157). Liu et al. disclose wherein the coating layer is LiFePO4 (paragraph 0166). Before the effective filing date of the invention it would have been obvious to one of ordinary skill in the art to modify the anode plate of Xu et al. to include the lithium-precipitation inhibiting layer containing at least one of the following lithium-precipitation inhibiting materials: LiFePO4, LiCoPO4, LiNiPO4, and LiMnPO4, because Liu et al. teach that these materials reduce the reaction with the electrolyte, increase life cycle, and lead to better performance such as high-rate properties of the battery (paragraph 0167).
13. Claim 5 is rejected under 35 U.S.C. 103 as being unpatentable over Xu et al. (CN 112151777 A), as applied to Claims 1, 3, 4, 9 and 12-16 above, and in further view of Nobuhiro et al. (JP 2013073924).
With regard to Claim 5, Xu et al. disclose the anode plate in paragraph 7 above, but do not specifically disclose wherein the lithium-precipitation inhibiting layer comprises lithium-precipitation inhibiting material and one or more binders.
Nobuhiro et al. disclose in Figure 1, an anode plate (2) for a lithium-ion battery, wherein the anode plate comprises: i) a current collector (10); ii) an anode active material layer (11) located on at least one surface of the current collector (top of 10); and iii) a lithium-precipitation inhibiting layer (12) (see Pg2:L29-34) located on the anode active material layer (11), wherein the lithium-precipitation inhibiting layer (12) contains at least one of following lithium-precipitation inhibiting materials: LiMPO4, and LTO (20) (see Pg1:L36-38, Pg4:L36-38). Nobuhiro teaches the lithium-precipitation inhibiting layer comprises one or more binders (Pg3:L21-24). Before the effective filing date of the invention It would have been obvious to one of ordinary skill in the art to modify the lithium-precipitation inhibiting layer of the embodiment of Fig. 3 of Nobuhiro to comprise a binder because Nobuhiro teaches such is an effective equivalent that would yield the same predictable result. Further, it has been held that combining two embodiments disclosed adjacent to each other in a prior art patent does not require a leap of inventiveness and involves only routine skill in the art.
14. Claims 6, 7, 8 and 10 are rejected under 35 U.S.C. 103 as being unpatentable over Xu et al. (CN 112151777 A), as applied to Claims 1, 3, 4, 9 and 12-16 above.
With regard to Claim 6, Xu et al. disclose the anode plate in paragraph 7 above, including wherein the lithium-precipitation inhibiting layer has a thickness of 1-100 nm (paragraph 0009), which meets the claimed limitation of 1.8-20 microns, but do not specifically disclose wherein the anode active material layer has a thickness of 30-340 microns, and the thickness of the lithium-precipitation inhibiting layer is 0.018-0.2 times that of the anode active material layer. Before the effective filing date of the invention it would have been an obvious matter of design choice to manufacture the anode active material layer to have a thickness of 30-340 microns, and the thickness of the lithium-precipitation inhibiting layer to be 0.018-0.2 times that of the anode active material layer, since such a modification would only involve a mere change in the size of a component. A change in size is generally recognized as being within the level of ordinary skill in the art. See MPEP 2144.04(IV).
With regard to Claim 7, Xu et al. disclose the anode plate in paragraph 7 above, including wherein the lithium-precipitation inhibiting layer has a thickness of 1-100 nm (paragraph 0009), which meets the claimed limitation of 2.3-15 microns, but do not specifically disclose wherein the anode active material layer has a thickness of 55-260 microns, and the thickness of the lithium-precipitation inhibiting layer is 0.023-0.11 times that of the anode active material layer. Before the effective filing date of the invention it would have been an obvious matter of design choice to manufacture the anode active material layer to have a thickness of 55-260 microns, and the thickness of the lithium-precipitation inhibiting layer to be 0.023-0.11 times that of the anode active material layer, since such a modification would only involve a mere change in the size of a component. A change in size is generally recognized as being within the level of ordinary skill in the art. See MPEP 2144.04(IV).
With regard to Claim 8, Xu et al. disclose the anode plate in paragraph 7 above, but do not specifically disclose wherein a potential difference between the lithium-precipitation inhibiting layer and the anode active material layer is 1-4 volts. Before the effective filing date of the invention it would have been obvious to one of ordinary skill in the art to manufacture the anode plate to have a potential difference between the lithium-precipitation inhibiting layer and the anode active material layer at 1-4 volts, since it has been held that discovering an optimum value of a result effective variable involves only routine skill in the art. See MPEP 2144.05.
With regard to Claim 10, Xu et al. disclose the anode plate in paragraph 7 above, but do not specifically disclose wherein a capacity ratio of the anode plate and the cathode plate is 1.07 to 1.01. Before the effective filing date of the invention it would have been obvious to one of ordinary skill in the art to manufacture the anode plate to have a capacity ratio of the anode plate and the cathode plate at 1.07 to 1.01, since it has been held that discovering an optimum value of a result effective variable involves only routine skill in the art. See MPEP 2144.05.
Response to Arguments
15. Applicant’s arguments, see pages 5-7, filed April 28, 2026, with respect to the rejection(s) of Claims 1-4 and 9 under 35 U.S.C. 102(a)(1) as being anticipated by Nobuhiro et al. (JP 2013073924), have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of Xu et al. (CN 112151777 A).
Conclusion
