Office Action

§102 §112
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 . Drawings The drawings were received on 5/5/2026. These drawings are acceptable. 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 applicant regards as his invention. Claim 5 is 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. Claim 5 recites the limitation, “wherein the at least one conductor includes at least one conductor…and at least one conductor….”. It is unclear whether “at least one conductor” in line 3 is the same or different as “at least one conductor” in line 2 and/or lines 1-2. As such the claim is indefinite for failing to distinctly claim the invention. 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.

Response to Arguments Applicant's arguments filed 5/5/2026 with regard to the 35 USC §102 rejections have been fully considered but they are not persuasive. Applicant argues Kovacic fails to disclose claims 1, 14 and 18 because Kovacic fails to disclose a second connection interface that receives an attachment having an electrical component and a power circuit and/or operational circuitry that supplies electrical power to the electrical component via the electrical interface. Examiner finds this argument unpersuasive. Applicant’s arguments amount to a general allegation without specifically pointing out how the language of the claims patentably distinguishes them from the reference. Applicant has made a conclusory argument that lacks support or reasoning for why Kovacic fails to disclose those limitations. As explained above, Kovacic describes in paragraphs [0028] and [0032] and shows in the figures 1-3, multiple electrical connections/hubs with switches between the hub/couplings and tools that has electrical components with paragraphs [0028] and [0032] describing tools that are connects to those couplings that contain electrical components and the power circuit and operation circuitry that supplies the electrical power. Applicant argues Benelli fails to disclose claims 1 and 14 because Benelli fails to disclose a second connection interface that receives an attachment having an electrical component and a power circuit and/or operational circuitry that supplies electrical power to the electrical component via the electrical interface. Examiner finds this argument unpersuasive. Applicant’s arguments amount to a general allegation without specifically pointing out how the language of the claims patentably distinguishes them from the reference. Applicant has made a conclusory argument that lacks support or reasoning for why Benelli fails to disclose those limitations. As explained above, Benelli discloses all those limitations in claims 1 and 14. Specifically, on the side of the stand blender is a coupler 515 that electrically connects to a controller 500 that has an electrical component and a power circuit and operational circuitry that supplies electrical power to the electrical component (see figures 5 and 7, #500, 515, 520, 565 and paragraphs [0022]; [0043]-[0046]; [0057]). 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.
