§102 §103
DETAILED ACTION Notice of Pre-AIA or AIA Status 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 2. Claims 1, 2, 5-13, 16 and 17 are pending. 3. This office action is in response to the Applicant’s communication filed 12/23/2025 in response to PTO Office Action mailed 09/24/2025. The Applicant’s remarks and amendments to the claims and/or the specification were considered with the results that follow. Response to Arguments 4. Applicant’s arguments with respect to the amended independent claims have been considered but are moot in view of the new ground(s) of rejection in which the Examiner has cited previously presented prior art, Kolar et al. (EP 3285627 B1 hereinafter “Kolar” – IDS Submission), as necessitated by the amended independent claims disclosing an additional accessory being of a type corresponding to a weighting unit (Kolar – Par. [0067]). Claim Rejections - 35 USC § 102 5. 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. 6. 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. 7. Claims 1, 5-12, 16 and 17 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Kolar et al. (EP 3285627 B1 hereinafter “Kolar” – IDS Submission). Referring to claim 1, Kolar discloses a kitchen appliance (Kolar – Figs. 1-5, blending system 100, 200, 300, 400, 500.), wherein the kitchen appliance comprises a base unit having a housing, an electric motor (Kolar – Par.

[0047] discloses the container 330 having a unique identifier.), the at least one accessory comprising a first accessory and a further accessory, each of the first accessory and the further accessory comprising a type of at least one of the following: a cutting unit, stirring unit, cooking unit, weighing unit, steaming unit, or any combination thereof (Kolar – Fig. 1 & par. [0028] disclose the container 120 to allow blade assembly 122 to chop, mix, blend, or otherwise interact with the foodstuff. Par. [0067] discloses the blender system 500 may utilize pressure sensors (e.g., weight sensors), or the like to determine when a user adds foodstuff to the container 560.), wherein the detector is configured to detect the identifier of the at least one accessory and to forward it to the controller (Kolar – Par. [0047-0052] disclose the NFC component 314 receiving an identifier of the container 330 so the base 310 (e.g., via processor 304) may receive the parameters and/or query the NFC component 334 to determine whether the container 330 is compatible with the base 310.), wherein the controller is configured to compare the detected identifier with identifiers from a database, wherein the controller is configured to, in the event of a match between the detected identifier and an unmarked identifier from the database, mark the matching identifier from the database as known, and provide cooking information associated with the matching identifier from the database via the communication interface, and wherein the controller is configured to make available at least one item of cooking information from the database, which is assigned to the identifier marked as known, via the communication interface if the detected identifier matches an identifier already marked as known (Kolar – Par. [0047-0052, 0055] disclose the NFC component 314 receiving an identifier of the container 330 so the base 310 (e.g., via processor 304) may receive the parameters and/or query the NFC component 334 to determine whether the container 330 is compatible with the base 310. The base 310 may identify container 330. Identifying container 330 may include identifying a make, model, a particular container (e.g., via a unique identifier), blade assembly utilized in the container, or the like. In an example, identifying the container may include determining a match between received data and data stored in memory 302. For example, a set of identifiers may be stored in a table or other data structure in memory 302. The NFC component 314 may receive an identifier from NFC component 334 and/or decode data received therefrom to determine an identifier. The identifier may then be compared to stored identifiers. See par. [0055] disclosing a user accessing a recipe that allows the user to identify a specific container 330 for the utilization for nuts.), wherein a position detector is provided and is configured to detect the position of the first accessory with respect to the base unit and with respect to the further accessory (Kolar – Figs. 1A-1B show a first accessory, blade assembly 122, of the container 120 with respect to the base unit 110 and with respect to a further accessory, lid 130 of the container 102.) and to forward it to the controller (Kolar – See par. [0026-0034, 0043-0047].), the type of the further accessory being different from the type of the first accessory (Kolar – Figs. 1A-1B & par. [0067] show the further accessory, container having weight sensors, being different from the type of the first accessory, blade assembly 122.), wherein the controller is configured to provide cooking information from the database in dependence on the detected position of the at least one accessory via the communication interface (Kolar – See par. [0026-0034, 0043-0047].), and wherein the controller is configured to provide cooking information from the database as a function of a plurality of detected identifiers and/or detected positions (Kolar – See par. [0039, 0043-47].). Referring to claim 5, Kolar discloses the kitchen appliance according to claim 1, wherein the controller is configured to block at least one preparation function in the event the detected identifier does not match an identifier from the database, and/or wherein the controller is configured to block at least one preparation function in the event of detecting the position of an accessory corresponding to an assembly of the accessory with the base unit and in the event of an aborted detection of an identifier (Kolar – See par. [0049].). Referring to claim 6, Kolar discloses the kitchen appliance according to claim 1, wherein the identifier is a coded data carrier with machine-readable information, and wherein the detector is configured to detect machine-readable information (Kolar – See par.

The processor 304 may receive the blending program from memory 302 and may generate instructions for the motor 312 and/or other components (e.g., a display - not shown) based on the blending program.). Claim Rejections - 35 USC § 103 8. 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. 9. Claims 2 and 13 are rejected under 35 U.S.C. 103 as being unpatentable over Kolar in view of Palmer et al. (US Pub. No. 2021/0204757 A1 hereinafter “Palmer” – IDS Submission). Referring to claim 2, Kolar discloses the kitchen appliance according to claim 1, however, fail to explicitly disclose wherein the communication interface is configured to detect a user input and to forward it to the controller, and in that the controller is configured to mark at least one cooking information selected by the user input among the cooking information provided as preferred cooking information, and in the event of a subsequent, renewed match of the same identifier, make the at least one item of cooking information marked as preferred cooking information available separately via the communication interface. Palmer discloses wherein the communication interface is configured to detect a user input and to forward it to the controller, and in that the controller is configured to mark at least one cooking information selected by the user input among the cooking information provided as preferred cooking information, and in the event of a subsequent, renewed match of the same identifier, make the at least one item of cooking information marked as preferred cooking information available separately via the communication interface (Palmer – See par. [0235].). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to include Palmer’s teachings with Kolar’s teachings for the benefit of implementing a food processor capable of integrating intelligently with multiple attachments, cloud-based services, wireless-communicating household appliances, smart meters, and household robots, to efficiently and safely complete a recipe made to conform to user preferences and characteristics (Palmer – par. [0005]). Referring to claim 13, Note the rejections of claim 2 above. The Instant Claim recites substantially same limitations as the above-rejected and is therefore rejected under same prior-art teachings. 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.
