Office Action

§102 §112
UNIT CELL INSPECTING DEVICE, ELECTRODE ASSEMBLY MANUFACTURING EQUIPMENT INCLUDING SAME, AND ELECTRODE ASSEMBLY MANUFACTURING METHOD 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. Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The information disclosure statements (IDS) submitted on 8/21/2023, 1/29/2025, 6/24/2025 are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statements are being considered by the examiner. Claim Rejections - 35 USC § 112 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 appl icant regards as his invention. Claims 1-15 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. Claims 1-3, 11, and 13-15 disclose the use of “long-wave infrared rays” without claiming a wavelength range. Paragraph 0064 of the as-filed specification defines “ the long-wave infrared rays refer to electromagnetic waves having a wavelength of about 700 nm and correspond to the outside of the red region of the light spectrum .” However, this is factually incorrect. Long-wave infrared rays have wavelengths ranging from 8000-12000 nm which far exceeds Applicant’s wavelength. Additionally, an electromagnetic wave having a wavelength of about 700 nm is certainly not in the IR region at all but in the visible region. In fact, red as the longest wavelength in the visible light region ranging from 620-700 nm. Therefore, the Applicant’s “long-wave infrared rays” are not at all infrared but visible. The Examiner has attached a reference explaining the infrared spectrum. The Examiner respectfully requests the Applicant to explain how the claimed “long-wave infrared rays” are indeed in the infrared region. Regarding claim 3, the term “high-temperature light” does not have a generally recognized meaning. Further, the specification provides its source comes from a “long-wave infrared lamp” (Paragraph 0024). However, as disclosed above, the specification defines “long-wave infrared” as being in the visible light region, not IR. Claims 4-10 and 12 are also rejected under 35 USC 112(b) for their dependence on claims 1 and 13. Claim Rejections - 35 USC § 102 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 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. Claim s 1 -3, 5, and 10-15 are rejected under 35 U.S.C. 102 (a)(1) as being anticipated by Aramaki et al. (US 2014/0027643 A1). Regarding claim 1 , Aramaki et al. teach a unit cell inspecting device ( Abstract) comprising an inspection unit for capturing an image of an edge of a unit cell by using long-wave infrared rays (Paragraphs 0046, 0047, 0049) and measuring a position of an edge of an electrode provided in the unit cell (Abstract) , wherein the inspection unit comprises: a main heating part configured to heat the edge of the unit cell, thereby raising a temperature of the edge of the electrode provided in the unit cell ( Figs. 6 and 12; Claims 7 and 8; Paragraph s 0047; 0064-0067 disclose electrode position detection devices, element 200, having infrared light sources, elements 72, 74, and 76, arranged above the four edges of the unit cell stack, elements 20/30.) ; and an image capturing part configured to capture the image of the edge of the unit cell by using the long-wave infrared rays, thereby acquiring a thermal image of the edge of the electrode provided in the unit cell (Figs. 6 and 12; paragraphs 0047, 0049, and 0064-0067 disclose cameras, elements 80, 82, and 84 arranged above the four edges of the unit cell stack. Paragraph 0068 discloses near-infrared light which is at a wavelength of 750-2500 nm. ) ; and an inspection part configured to measure the edge of the electrode in the thermal image captured by the image capturing part, thereby measuring the position of the electrode by using the measured edge of the electrode ( Fig. 5; Paragraph 0071 disclose a control unit, element 160, detects positions of the electrodes based on the images taken by the cameras.) .

Regarding claim 3 , Aramaki et al. teach the unit cell inspecting device of claim 1, wherein the image capturing part is provided with four long-wave infrared cameras that respectively capture the images of edges of the unit cell (Figs. 6 and 12; paragraphs 0047, 0049, and 0064-0067 disclose cameras, elements 80, 82, and 84 arranged above the four edges of the unit cell stack.) , the main heating part is provided with four long-wave infrared lamps that respectively heat the edges of the unit cell by using high-temperature light, thereby raising the temperature of the electrode provided in the unit cell (Figs. 6 and 12; Claims 7 and 8; Paragraphs 0047; 0064- 0067 disclose electrode position detection devices, element 200, having infrared light sources, elements 72, 74, and 76, arranged above the four edges of the unit cell stack, elements 20/30.) , and the four long-wave infrared lamps are respectively coupled to the four long-wave infrared cameras (Fig. 12 shows the infrared lights coupled to the cameras and surrounded four edges of the cell.) . Regarding claim 5 , Aramaki et al. teach the unit cell inspecting device of claim 1, further comprising a conveyance unit which conveys the unit cell to the inspection unit (Fig. 5, elements 60, 62, and 64 disclose suction conveyers.) . Regarding claim 10 , Aramaki et al. teach the unit cell inspecting device of claim 1, wherein the electrode comprises a negative electrode (Abstract). Regarding claim 11 , Aramaki et al. teach electrode assembly manufacturing equipment comprising: a unit cell supply device configured to supply a unit cell; the unit cell inspecting device of claim 1, which uses the long-wave infrared rays to capture the image of an edge of the unit cell supplied by the unit cell supply device ( Paragraphs 0046, 0047, 0049) , measures the position of the edge of an electrode provided in the unit cell, and uses the measured edge of the electrode to measure the position of the electrode (Paragraph 0077) ; and a unit cell placing device configured to sequentially place unit cells on the basis of the position of the electrode measured by the unit cell inspecting device (Paragraphs 0075-0076) .
