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 . Claim Rejections - 35 USC § 103 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 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. Claim(s) 1-5, 8-18 and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over LEE et al. (US 2018/0277804 A1, hereinafter LEE) in view of FUNABIKI et al. (US 2020/0180044 A1, hereinafter FUNABIKI). PNG media_image1.png 810 520 media_image1.png Greyscale PNG media_image2.png 392 768 media_image2.png Greyscale Regarding claims 1 and 16 (claim 1 is considered representative for limitation matching purposes), LEE discloses a rechargeable battery assembly for a kitchen appliance, comprising: a charging base (See Figs.2-3, Item#40, disclose a charging base), comprising: a plug according to a standardized connection specification (See Figs.2-3, Item#46 disclose a USB port and a USB cable 60, the combination of the USB port and the USB cable comprising the USB plug [output end of the wire 60 comprising an output plug which connects to the battery 20); and a battery (See Figs.2-3, Item#20), comprising: a receptacle according to the standardized connection specification and configured to mate with the plug to selectively engage the battery with the charging base (See Figs.2-3, Item#26 disclose a USB port [receptacle] for receiving the plug of the charging base [connected wire 60]); a plurality of battery terminals (See Fig.1, Item#24 and Par.31, disclose a battery physical interface comprising battery terminals to couple the battery 20 to a charger of similar configuration via charger physical interface [Fig.1, Item#44]). However, LEE does not explicitly disclose the charging base comprising: a body having a pair of notches disposed adjacent a perimeter thereof; and the battery comprising: a plurality of tabs configured to move inwardly by initial engagement with corresponding notches in the charging base and to move outward behind the corresponding notches when the battery is fully received in the charging base, thereby defining a charging position; and first and second buttons associated with respective ones of the plurality of tabs, the first and second buttons each being configured to move the respective tabs inward for release from the notches to remove the battery from the charging position. FUNABIKI discloses a body having a pair of notches disposed adjacent a perimeter thereof (See Fig.3, Item#16 and Par.48, disclose engaging grooves. The examiner explains that even though FUNABIKI does not explicitly disclose that the notches are placed on a charger, it is well known the locking receiving mechanism placed on a power tool is also placed on the charger to attach the battery to a battery powered device and a charging device as evidenced by KONDO, US 2019/0280501 A1. Par.70, discloses the battery comprising a hook 38 to attach the battery to a power tool and to the charger); a battery (See Fig.4, Item#20a, discloses a battery pack) comprising: a plurality of tabs configured to move inwardly by initial engagement with corresponding notches in the charging base (See Fig.4, Items#28 and Pars.48 and 53, disclose claws which engage with engaging grooves [i.e. notches] 16 on a complementary body of a power supply section 11c) and to move outward behind the corresponding notches when the battery is fully received in the charging base, thereby defining a charging position (See Par.48, discloses the claws 28 engage with the grooves 16. The examiner explains that even though FUNABIKI does not explicitly disclose that the battery claws engage a charger, it is well known the locking claws [attachment mechanism] of the battery is used to attach the battery to a battery powered device and a charging device as evidenced by KONDO, US 2019/0280501 A1. Par.70, discloses the battery comprising a hook 38 to attach the battery to a power tool and to the charger); first and second buttons associated with respective ones of the plurality of tabs, the first and second buttons each being configured to move the respective tabs inward for release from the notches to remove the battery from the charging position (See Fig.4, and Par.48, disclose push buttons 27 which control claws 28 to engage and disengage from a corresponding device; that device being a power tool or a charger). LEE and FUNABIKI are analogous art since they both deal with battery packs. It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the invention disclosed by LEE with the teachings of FUNABIKI by adding the disclosed plurality of tabs and buttons to the battery and the plurality of notches structure [i.e. charger and power tool] for the benefit of securing the battery to the charger and the electronic device. The examiner further explains that even though LEE and FUNABIKI do not disclose the rechargeable battery assembly is for a kitchen appliance, the examiner explains that a recitation of the intended use of the claimed invention must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use, then it meets the claim. The examiner argues that the disclosed battery pack is capable of providing power to a kitchen appliance instead of a power tool as long as the power tool comprises a compatible battery attachment mechanism. Regarding claim 2, LEE and FUNABIKI disclose the rechargeable battery assembly for a kitchen appliance of claim 1, wherein the battery terminals are configured to align with terminals of a battery-receiving cavity of an appliance for electrical connection therewith (See LEE, Pars.16 and 40, disclose the battery pack is for attachment powering a power tool, the alignment of the terminals of the battery pack terminals and the power tool is inherent for the battery pack to provide power to the power tool.

Regarding claim 3, LEE and FUNABIKI disclose the rechargeable battery assembly for a kitchen appliance of claim 2 as discussed above, wherein the charging base further comprises: a recess defined in the body and sized to passively receive the plurality of battery terminals (See LEE, Fig.2 discloses the charger comprising a physical interface 44 comprising a recess in which the battery pack 20 [Fig.1] fits to be charged). Regarding claim 4, LEE and FUNABIKI disclose the rechargeable battery assembly for a kitchen appliance of claim 1 as discussed above, However, LEE and FUBNABIKI as applied to claim 1 do not disclose wherein the pair of notches are on opposing sides of the body of the charging base. FUNABIKI further discloses the pair of notches are on opposing sides of the body of the receiving device (See Fig.2B, Items#16, disclose a pair of groove son opposite sides for receiving the hooks [Fig.4, Items#28] on both sides of the battery pack). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the invention disclosed by LEE with the further teachings of FUNABIKI by placing the notches on opposite sides of the body of the charging base of LEE for the benefit of matching the disclosed tabs and locking and securing the battery pack to the charging base. Regarding claim 5, LEE and FUNABIKI disclose the rechargeable battery assembly for a kitchen appliance of claim 1 as discussed above, However, LEE and FUNABIKI do not disclose wherein the pair of notches include indentations having ramped portions to engage and retain the battery. FUNABIKI further discloses wherein the pair of notches include indentations having ramped portions to engage and retain the battery (See Fig.3, Items#16, disclose the indentation comprising an inclined portion to receive the hooks 28). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the invention disclosed by LEE and FUNABIKI with the further teachings of FUNABIKI such that the pair of notches include indentations having ramped portions for the benefit of engaging and retaining the battery pack until the user actuates the buttons to manipulate the tabs to disengage the notches.

The battery terminals are in the charger recess when the battery is coupled to the charging base) and a receptacle configured to mate with the charging base when the battery is fully received in the charging base, thereby defining a charging position (See LEE, Fig.1, discloses the battery 20 physical interface comprising a receptacle area to receive the physical charging interface 44 of the charger 40). However, LEE does not disclose a pair of notches disposed adjacent the perimeter edge and that the battery assembly is for a kitchen assembly. FUNABIKI discloses a body having a pair of notches disposed adjacent a perimeter thereof (See Fig.3, Item#16 and Par.48, disclose engaging grooves. The examiner explains that even though FUNABIKI does not explicitly disclose that the notches are placed on a charger, it is well known the locking receiving mechanism placed on a power tool is also placed on the charger to attach the battery to a battery powered device and a charging device as evidenced by KONDO, US 2019/0280501 A1. Par.70 discloses the battery comprising a hook 38 to attach the battery to a power tool and to the charger). LEE and FUNABIKI are analogous art since with since they both deal with battery packs. It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the invention disclosed by LEE with the teachings of FUNABIKI by adding the plurality of tabs and buttons to the battery and the plurality of notches structure [i.e. charger and power tool] for the benefit of securing the battery to the charger and the electronic device. The examiner further explains that even though LEE and FUNABIKI do not disclose the rechargeable battery assembly is for a kitchen appliance, the examiner explains that a recitation of the intended use of the claimed invention must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use, then it meets the claim.
