Office Action

§102
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 . 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 for the rejection will not be considered a new ground of rejection if the picrate or art relied upon, and the rationale supporting the rejection, would be the same under either status. DETAILED ACTION This is a response to the amendment filed on 08/05/25. The applicant argument regarding Verbrugge et al. is not persuasive; therefore, all the rejections based on Verbrugge et al. and is retained and repeated for the following reasons. 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. Claims 1-4 rejected under 35 U.S.C. 102(a)(1) as being anticipated by Verbrugge et al. (US Pub. 2014/0131059). As to claim 1 the prior art teaches a rechargeable battery device of a cordless power tool, comprising: a circuit board as a carrier disposed inside thereof, wherein said circuit board has a rechargeable battery arranged at an upper end thereof, and a power indicator light and a power transmission connection port arranged at a lower end thereof respectively (see fig 1-7 paragraph 0036-0046; especially, Verbrugge et al. teach a circuit board as a carrier disposed inside thereof, wherein said circuit board has a rechargeable battery arranged at an upper end thereof, and a power indicator light and a power transmission connection port arranged at a lower end thereof respectively (see fig 1-7 paragraph 0037-0044), wherein said power transmission connection port a Universal Serial Bus (USB) connector as the connection interface, so that said rechargeable battery device is allowed to be used as a portable charging device (power bank) to charge other electronic devices, which improves the application and practicability of said rechargeable battery device (see fig 5-13 paragraph 0046-0057 and summary; especially, Verbrugge et al. teach wherein said power transmission connection port a Universal Serial Bus (USB) connector as the connection interface, so that said rechargeable battery device is allowed to be used as a portable charging device (power bank) to charge other electronic devices, which improves the application and practicability of said rechargeable battery device as fig 5-13 paragraph 0047-0055 and summary). As to claim 2, the prior art teaches wherein one of said connection ports allows a Universal Serial Bus Type-C (USB-C) connector to provide a variety of connection interfaces and increase the practicability of charging connections for different devices (see fig 5-13 paragraph 0067-0076). As to claim 3 the prior art teaches wherein one of said connection ports allows a Universal Serial Bus Type-A (USB- A) connector to provide a variety of connection interfaces and increase the practicability of charging connections for different devices (see fig 5-14 paragraph 0080-0086). As to claim 4 the prior art teaches wherein said rechargeable battery is implemented as one or more cylindrical battery arranged in series or parallel according to the required power (see fig 5-15 paragraph 0083-0088). Remarks Applicant’s response and remarks filed on 08/05/25 have been carefully reviewed. Applicant’s arguments have been fully considered but they are not persuasive. Key argument and their response related to the claims are listed as below: Applicant contends that Verbrugge et al. do not describe “a circuit board as a carrier disposed inside thereof, wherein said circuit board has a rechargeable battery arranged at an upper end thereof, and a power indicator light and a power transmission connection port arranged at a lower end thereof respectively (see fig 1-7 paragraph 0036-0046; especially, Verbrugge et al. teach a circuit board as a carrier disposed inside thereof, wherein said circuit board has a rechargeable battery arranged at an upper end thereof, and a power indicator light and a power transmission connection port arranged at a lower end thereof respectively (see fig 1-7 paragraph 0037-0044)” probes as claimed, Examiner respectfully disagrees. The prior art (Verbrugge et al. US Pub. 2014/0131059) do teach a circuit board as a carrier disposed inside thereof, wherein said circuit board has a rechargeable battery arranged at an upper end thereof, and a power indicator light and a power transmission connection port arranged at a lower end thereof respectively (see fig 1-7 paragraph 0036-0046; especially, Verbrugge et al. teach a circuit board as a carrier disposed inside thereof, wherein said circuit board has a rechargeable battery arranged at an upper end thereof, and a power indicator light and a power transmission connection port arranged at a lower end thereof respectively (see fig 1-7 paragraph 0037-0044). Applicant contends that Verbrugge et al. do not describe “wherein said power transmission connection port a Universal Serial Bus (USB) connector as the connection interface, so that said rechargeable battery device is allowed to be used as a portable charging device (power bank) to charge other electronic devices, which improves the application and practicability of said rechargeable battery device” probes as claimed, Examiner respectfully disagrees. The prior art (Verbrugge et al. US Pub. 2014/0131059) do teach wherein said power transmission connection port a Universal Serial Bus (USB) connector as the connection interface, so that said rechargeable battery device is allowed to be used as a portable charging device (power bank) to charge other electronic devices, which improves the application and practicability of said rechargeable battery device (see fig 5-13 paragraph 0046-0057 and summary; especially, Verbrugge et al. teach wherein said power transmission connection port a Universal Serial Bus (USB) connector as the connection interface, so that said rechargeable battery device is allowed to be used as a portable charging device (power bank) to charge other electronic devices, which improves the application and practicability of said rechargeable battery device as fig 5-13 paragraph 0047-0055 and summary) Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any extension fee pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
