Office Action

§102 §103
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 . Response to Arguments Applicant’s responses, see “Claim Objections” on page 7 of “REMARKS”, filed 02/17/2026, with respect to Claim Objections have been fully considered and are persuasive. The objection of claims 1-3 has been withdrawn. Applicant’s arguments: PNG media_image1.png 242 640 media_image1.png Greyscale PNG media_image2.png 180 636 media_image2.png Greyscale PNG media_image3.png 438 640 media_image3.png Greyscale PNG media_image4.png 358 640 media_image4.png Greyscale PNG media_image5.png 458 638 media_image5.png Greyscale PNG media_image6.png 366 638 media_image6.png Greyscale PNG media_image7.png 450 642 media_image7.png Greyscale PNG media_image8.png 180 640 media_image8.png Greyscale Examiner’s responses: In response to applicant's argument that the references fail to show certain features of the invention, it is noted that the features upon which applicant relies (i.e., the warming member is spaced apart from the battery assembly) were not recited in the rejected independent claim 1. Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993). However, in this case, as shown in fig. 2 and fig. 8, there are other components, such as items 33, disposing between the warming member or item 32 and the battery assembly or item 101. Thus, the warming member 32 is spaced apart from the battery assembly 101. Therefore, Yoshida still reads on the amended independent claim 1. 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.

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claim invention to further modify the method of manufacturing the sealed battery of Yoshida with the drying oven includes: a pair of heaters attached to the pair of first walls, respectively, as taught by Woo, for providing a more evenly heat transfer to an object to be dried, such as battery, etc. …, which would result in effectively drying the object to be dried within a shorter period of time. Thus, the manufacturing costs are further reduced and thus further benefit the consumer. Regarding claim 17, Yoshida as modified discloses wherein in the drying, the shutter (front door of chamber 51, [0048]; thus, front door should be on left wall or front wall of chamber 51 at item 27, fig. 8) (King, 14, fig. 2) (King, 15, fig. 2) is closed to seal the drying oven (20, fig. 8), the drying oven (20, fig. 8) is heated to a predetermined temperature (predetermined temperature, [0031]) by the pair of heaters (Woo, 20, 20, figs. 1, 2) to dry the battery assembly (101, fig. 8), and the pair of warming members (32, 32, figs. 8, 4) (in this case, item 22 is a table and also a heater, [0043]; therefore, heat from the item 22 would transfer to the item 32, and thus, the item 32 would be warmed or become a warming member) retains heat from the pair of heaters (Woo, 20, 20, figs. 1, 2) to further dry the battery assembly (101, fig. 8). Claims 18 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Yoshida, King and Woo as applied to claim 17 above, and further in view of Sugiyama (US 2019/0252670). PNG media_image22.png 394 458 media_image22.png Greyscale Regarding claims 18 & 19, Yoshida as modified discloses wherein in the drying, an inside of the drying oven (20, fig. 8) is depressurized to a pressure (5 to 15 kPa (abs), [0032]) after the drying oven (20, fig. 8) is heated to the predetermined temperature (predetermined temperature, [0031]); (Application claim 18) and wherein the predetermined temperature (predetermined temperature, [0031]) is a range of 100°C to 105°C ([0031]). (Application claim 19) Yoshida does not disclose an inside of the drying oven is depressurized to a pressure of 500 Pa or less; (Application claim 18) and the predetermined temperature is a range of 110°C to 140°C. (Application claim 19) Sugiyama teaches an inside of the drying oven (Sugiyama, 200, fig. 3) is depressurized to a pressure of 500 Pa or less (Sugiyama, 600 Pa or lower, [0050]; thus, the depressurized pressure can be 500 Pa or lower); (Application claim 18) and the predetermined temperature (Sugiyama, target temperature range, [0048]) is a range of 110°C to 140°C (Sugiyama, 115°C to 145°C, [0048]). (Application claim 19) It would have been obvious to one of ordinary skill in the art before the effective filing date of the claim invention to further modify the method of manufacturing the sealed battery of Yoshida with the inside of the drying oven is depressurized to a pressure of 500 Pa or less; (Application claim 18) and the predetermined temperature is a range of 110°C to 140°C. (Application claim 19), as taught by Sugiyama, for effectively removing the moisture or humidity inside the drying oven which would result in producing high quality products. Thus, the drying oven operates more efficiently and thus benefits the consumer. Allowable Subject Matter Claims 10 and 12 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: As to claim 10, the prior art of record fails to disclose or suggest alone or in combination as claimed the method according to claim 1, wherein the placing table includes: a substrate, and a warming member holder formed as a recess in an upper surface of the substrate, and the warming member is fitted into the warming member holder. The art of record does not disclose the above limitations, nor would it be obvious to modify the art of record so as to include the above limitations. Although Yoshida discloses “wherein the placing table (22, fig. 8) includes: a substrate (in this case, item 22 is a placing table and also a substrate, fig. 8, which is the same as the placing table 10 of the instant application is also a substrate 12 as shown in fig. 2 of the instant application), …”. However, Yoshida does not disclose the limitations of “the placing table includes: … a warming member holder formed as a recess in an upper surface of the substrate, and the warming member is fitted into the warming member holder.” Therefore, allowance of claim 10 is indicated because the prior art of record does not show or fairly suggest “the placing table includes: … a warming member holder formed as a recess in an upper surface of the substrate, and the warming member is fitted into the warming member holder” in combination with the structural elements and/or method steps recited in at least claim 10. As to claim 12, the prior art of record fails to disclose or suggest alone or in combination as claimed the method according to claim 11, wherein the supports are formed of the same material as the warming member. The art of record does not disclose the above limitations, nor would it be obvious to modify the art of record so as to include the above limitations. Although Yoshida as modified discloses “The method according to claim 11”. However, Yoshida does not disclose the limitations of “wherein the supports are formed of the same material as the warming member.” Therefore, allowance of claim 12 is indicated because the prior art of record does not show or fairly suggest “wherein the supports are formed of the same material as the warming member” in combination with the structural elements and/or method steps recited in at least claim 12. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee.
