Office Action

§102 §103 §112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Election/Restrictions Applicant's election with traverse of Group III in the reply filed on 6/10/2026 is acknowledged. The traversal is on the ground(s) that each subcombination presented by the Examiner includes the limitations of Claim 1. This argument is persuasive, and the restriction requirement has been withdrawn. Claims 1-20 are under examination. Claim Objections Claim 1 is objected to because of the following informality: Claim 1 recites “A battery pack, comprising: a housing a plurality of cells arranged in the housing” on line 1 of the claim. Although the claim is clear and not indefinite, please separate “a housing” and “a plurality of cells arranged in the housing” by a comma or semicolon (i.e., “a housing, a plurality of cells arranged in the housing” or “a housing; a plurality of cells arranged in the housing”). Appropriate correction is required. Claim 4 is objected to because of the following informality: Claim 4 recites “a first tab” on line 2 of the claim, but then recites “the tab” on line 3. Although the claim is clear and not indefinite, please change “the tab” on line 3 to “the first tab” to ensure proper antecedent basis. Appropriate correction is required. Claim 19 is objected to because of the following informality: Claim 19 recites “the battery pack comprises a plurality of first supporting portions and a plurality of second supporting portions; the plurality of first supporting portions and the plurality of second supporting portions are disposed between the first protrusion and the second protrusion” on lines 4-6 of the claim. Although the claim is clear and not indefinite, Claim 1 already sets forth a first supporting portion and a second supporting portion. To ensure proper antecedent basis, please change “a plurality of first supporting portions and a plurality of second supporting portions” in Claim 19 to “a plurality of the first supporting portions and a plurality of the second supporting portions.” Please also change “the plurality of first supporting portions and the plurality of second supporting portions” in Claim 19 to “the plurality of the first supporting portions and the plurality of the second supporting portions.” Appropriate correction is required. Claim Rejections - 35 USC § 112(b) The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 11 is 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 11, which depends upon Claim 10, recites “the second groove is provided on the second protrusion” on lines 3-4 of the claim. It is unclear how the first groove can be disposed on the first protrusion (as required by Claim 10), and also have the second groove disposed on the second protrusion. The instant disclosure teaches the first protrusion (13) and second protrusion (14) are on opposite sides of the module (in the second direction, see Examiner’s Annotations to Fig. 2). The connecting piece (80), which has the first and second grooves, does not span across the module in the second direction to connect to 13 and 14. Instead, it is mounted along the first direction of the module (see Fig. 4): PNG media_image1.png 442 810 media_image1.png Greyscale PNG media_image2.png 724 680 media_image2.png Greyscale Instant Fig. 2 Annotated by Examiner (L) and Instant Fig. 4 (R) Examiner requests Applicant amend the claim to clarify the orientation of the connecting piece. Since the instant disclosure supports the connecting piece being mounted along the first direction of the module, with the first and second grooves disposed on protrusions that are vertically aligned (in the third direction), the claim will be interpreted as “the second groove is disposed on a third protrusion.” See Claims 14 and 15 for definitions of the third protrusion that are consistent with this interpretation. Appropriate correction is required. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.

Regarding Claim 19, Hu discloses all limitations as set forth above. Hu discloses the first protrusion is arranged continuously in the first direction, and the second protrusion is arranged continuously in the first direction ([0040, 0059], see limiting ribs 7 arranged continuously in the first direction in Fig. 2); the battery pack comprises a plurality of the first supporting portions and a plurality of the second supporting portions (plurality of frame members 53 [0008], Annotated Fig. 2); the plurality of the first supporting portions and the plurality of the second supporting portions are disposed between the first protrusion and the second protrusion ([0040], see Figs. 2-6). PNG media_image12.png 724 1042 media_image12.png Greyscale Hu – Annotated Fig. 2 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. 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. This application currently names joint inventors. 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. Claims 7-11 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Hu as applied to Claims 1 and 4 above, and further in view of Yang, KR 20200124478 A. Regarding Claim 7, Hu discloses all limitations as set forth above. Hu discloses the first supporting portion (56) is arranged on an interior side of the first protrusion (interior portion of 7b, see Figs. 2 and 6). Hu does not disclose the first welding portion (84) “is disposed on the first circuit board.” However, this limitation is taught by Yang. Yang teaches a battery module connection device, wherein a connector (screw 28) electrically and physically connects a circuit board (substrate 20) to a first welding portion (busbar 30 [0004, 0022, 0032], Figs. 1-5). Yang teaches the connector ensures the circuit board is electrically connected to the busbar, in order for the circuit board to sense current flow and send a signal to the Cell Manage Unit ([0004, 0021]). Before the effective filing date of the present invention, it would have been obvious to a person of ordinary skill in the art to connect the first circuit board of Yang to the first welding portion of Hu, in the battery module of Hu, in order to monitor cell voltage and manage the battery module. PNG media_image13.png 596 1150 media_image13.png Greyscale Modified Hu Regarding the limitation “when viewed in the first direction, a first circuit board and the first supporting portion are arranged on two opposite sides of the first protrusion,” Hu discloses the first supporting portion (56) is arranged on an interior side of the first protrusion (interior portion of 7b, see Figs. 2 and 6). The structure of Modified Hu would have the circuit board (Yang, 20) mounted to the first welding portion (84) on Hu’s connecting piece (83), which is on an exterior side of the first protrusion (7b). Regarding Claim 8, modified Hu discloses all limitations as set forth above. Modified Hu discloses the battery pack further comprises a connecting piece (Hu, busbar support 83 [0052], Figs. 3, 6, 7); wherein the connecting piece comprises a connecting plate (Hu, base plate 831), a first connecting portion and a second connecting portion (Hu, two side plates 832), the first connecting portion and the second connecting portion are arranged at two opposite ends of the connecting plate (Hu, the busbar support 83 is U-shaped and includes a base plate 831 and two side plates 832 disposed opposite to each other on both sides of the base plate 831 [0052]); the first circuit board (Yang, 20) is disposed between the first connecting portion and the second connecting portion (see Modified Hu): PNG media_image14.png 602 1244 media_image14.png Greyscale Modified Hu Regarding Claim 9, modified Hu discloses all limitations as set forth above. Modified Hu does not disclose “the connecting piece further comprises a fixing portion, and the fixing portion is disposed on the connecting plate, wherein the fixing portion fixes the first circuit board to the connecting piece.” However, this limitation is also taught by Yang. Yang teaches a fixing portion is disposed on a connecting piece (connecting screw 28 and connecting boss 17 on base 10 [0029-0032], Figs. 2-4). Yang teaches the fixing portion (17 and 28) fixes the first circuit board (20) to the connecting piece ([0032-0035], Fig. 4). Yang teaches this fixing structure is advantageous, since the battery module connection device (10/20/30) can be removed and reinstalled if a defective battery in the module needs to be replaced ([0045]). Before the effective filing date of the present invention, it would have been obvious to a person of ordinary skill in the art to add the fixing portion of Yang (28/17) to the connecting piece of modified Hu (Hu, 83), in order to reattach the circuit board after being removed from the module. PNG media_image15.png 246 400 media_image15.png Greyscale Yang – Fig. 4 Regarding Claim 10, modified Hu discloses all limitations as set forth above. Modified Hu discloses the first connecting portion (Hu, 832) is provided with a first groove (Hu, bracket side plates 832 are respectively provided with bracket slots 834 [0054]), and the first groove is provided on the first protrusion (Hu, plates 832 are mounted to rail 7b via hooks 563 engaging with slots 834 [0016-0020, 0040, 0054], Figs. 5-7). Regarding Claim 11, modified Hu discloses all limitations as set forth above. Modified Hu discloses the second connecting portion (Hu, 832) is provided with a second groove (Hu, bracket slots 834) and a third groove (Hu, bracket fixing hooks 836), the second groove and the third groove are provided on two opposite sides of the first circuit board (Hu Fig. 7), the second groove is disposed on the third protrusion (see 35 USC 112(b) Section) (Hu, plates 832 are mounted to rail 7b via hooks 563 engaging with slots 834 [0016-0020, 0040, 0054], Figs. 5-7); the battery pack further includes a connection structure disposed on the first circuit board (Yang, connecting part 24 formed along lower edge of substrate 20 [0031]), at least a part of the connection structure is disposed in the third groove (Yang’s connecting part 24 would abut an inner portion of Hu’s bracket fixing hooks 836 and/or be disposed between Hu’s bracket fixing hooks 836 and busbar bracket 83). Regarding Claim 20, modified Hu discloses all limitations as set forth above. Modified Hu does not disclose the battery pack is accommodated in a body of an electric apparatus. However, this limitation is also taught by Yang. Yang teaches battery modules are used in electric vehicles to supply the required amount of power to the vehicle ([0003]). Yang’s electric vehicle is consistent with the instant disclosure’s definition of an electric apparatus and body at [0082] of the published specification: “Further, the electric apparatus may be an electric vehicle, an electric bus, an electric car, or the like, and the body is a vehicle structure. The battery pack 100 is provided in the vehicle to supply power.” Before the effective filing date of the present invention, it would have been obvious to a person of ordinary skill in the art to add the battery pack of modified Hu to the electric vehicle of Yang, as Yang teaches the battery pack is suitable for providing power to the vehicle.
