Office Action

§102
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 Amendment Acknowledgement is made of amendment filed on 04/21/2026 in which claims 1,3-5,7,11 and 17 are currently amended, claims 2 and 16 have been canceled while claim 21 has been newly added. By this amendment, claims 1,3-15, and 17-21 are now pending in the application. Information Disclosure Statement The information disclosure statement (IDS) submitted on 05/11/2026 has been considered and put on record. An initialed copy is attached herewith. Response to Arguments Applicant’s arguments with respect to claim(s) claims 1,3-15 and 17 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. New rejection of newly added claim 21 has been made in view of Levine as set forth below. 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 21 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by USPAT 7,731,386 B2 to Levine. Regarding claim 21: Levine at least discloses and shows in Figs. 1-2 and 7: A lighting device(100) for standing on a ground and illuminating a work region, comprising: a support mechanism(102); a lighting mechanism(light bar 104 + light source housing 124+connector portion 126 + ten lighting elements 128) comprising a lamp head(104) for emitting light, and a connection mechanism(connector portion 126) for supporting the lamp head(104), wherein the connection mechanism is connected to the support mechanism, wherein the support mechanism comprises a base(base 102) and a single support leg, the lighting device has a standing mode(Fig. 1) and a storage mode(Fig. 2), and, in the standing mode(Fig. 1), the lighting device(100) is supported by a resting surface(top surface of base 102 on the groove 6) of the support mechanism(102), and the resting surface comprises at least one end of the support leg(110,114)(note-The base 102 includes a groove 106 recessed into its top surface. The groove 106 extends between a closed end 108 near a first end 110 of the base 102 and an open end 112 at a second end 114 of the base)(see col. 3, line 20-col. 4, line 62; col. 6, lines 16-36). Accordingly claim 21 is clearly anticipated.

The prior art of record either taken alone or in combination thereof fails to teach or reasonably suggest, in the claimed combination: As in claim 1: A power tool body configured to be adapted to a first battery pack having a first nominal voltage and a first output terminal set and a second battery pack having a second nominal voltage, different than the first nominal voltage, and a second output terminal set; wherein the power tool body comprises a first input terminal set configured to be selectively electrically connected to one of the first output terminal set and the second output terminal set to supply power to the power tool body, and wherein the power tool body comprises a controller configured to acquire a connection state of a preset terminal in the first input terminal set and determine, according to the connection state of the preset terminal, that the first battery pack or the second battery pack is connected to the power tool body. As in claim 17: A power tool system, comprising: a power tool body; and a first battery pack having a first nominal voltage and a first output terminal set; wherein the power tool body is directly connectable to the first battery pack, the power tool body is configured to be further directly connectable to a second battery pack having a second nominal voltage and a second output terminal set when the first battery pack is not mounted on the power tool body, the first nominal voltage is different from the second nominal voltage, the first output terminal set is different from the second output terminal set, and the power tool body comprises a first input terminal set configured to be selectively electrically connected to one of the first output terminal set and the second output terminal set to supply power to the power tool body. Claims 3-15 depend either directly or indirectly from claim 1 and thus are also allowed for the same reasons. Claims 18-20 depend either directly or indirectly from claim 17 and thus are also allowed for the same reasons. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). 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 nonprovisional extension fee (37 CFR 1.17(a)) 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.
