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 . Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the actuator as set forth in claims 6, 7, 8, 9, 15 and 19; the first conductor as set forth in claim 5; the second conductor as set forth in claim 5 must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: “an electrical component” in claim 1, 2, 3, 4, 5, 14, 15, 18 and 19; “a first wireless communication device” in claim 5; and “a second wireless communication device” in claim 5. Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. 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(s) 1-9 and 11-20 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Kovacic et al. (U.S. Patent Pub. No. 2009/0084274). Regarding Claim 1, Kovacic et al. discloses A food processing apparatus (figure 1, reference #1), comprising: a body (figure 1, reference #2); a first connection interface disposed on the body and configured to selectively receive a mixing tool (figure 1, reference #15 and 17); a drive unit disposed in the body and configured to rotate the mixing tool via the first connection interface (figure 1, reference #3; [0028]); a second connection interface disposed on the body (figure 1, reference #15, 27 and 30) and configured to selectively receive an attachment having an electrical component (figure 2, reference #18, 31 and 32; [0028]; [0029]; [0032]) (it is noted that the limitation uses the term “configured” which only requires the second connection interface be capable of receiving an attachment, and therefore does not require the structural limitation of the attachment and its subparts (an electrical component) as part of the limitations of the claim), wherein the second connection interface includes an electrical interface (figures 2 and 3, reference #21, 22, 25; [0028]); and a power circuit configured to supply electrical power to the electrical component via the electrical interface (figure 1, reference #4). Regarding claim 2, Kovacic et al. discloses control circuity in communication with the drive unit (reference #4 and 5; [0028]); and a communication circuit providing communication between the control circuitry and the electrical component when the attachment couples with the body (figure 1, reference #28; [0028]; [0029]). Regarding claim 3, Kovacic et al. discloses wherein the communication circuit includes at least one conductor at the electrical interface (figure 1, reference #25; figure 2, reference #21 and 22; [0028]), wherein the control circuitry is configured to electrically communicate data with the electrical component via the at least one conductor (figure 1, reference #4, 5, 25 and 28; figure 2, reference #21 and 22; [0028]). Regarding claim 4, Kovacic et al. discloses a wireless communication network ([0028]-[0029]) having a first wireless communication device disposed in the body (figure 2, reference #22) and a second wireless communication device disposed in the attachment (figure 2, reference #32).

As stated above in the rejection to claim 1, the attachment and its subparts (the electrical component) are not positively recited structures of the claims, and therefore the limitations as recited in claim 6 which further limit the electrical component are not positive structural limitations that are part of the claim. However, in order to further prosecution, Kovacic et al. discloses wherein the electrical component includes an actuator that actuates in response to the electrical power being supplied to the electrical component from the power circuit ([0017]-[0018]; [0022]; [0028]-[0029]; [0032]). Regarding claim 7, Kovacic et al. discloses wherein the drive unit is configured to drive a food processing operation of the attachment and the actuator is configured to selectively interrupt driving of the food processing operation based on the supply of the electrical power to the actuator ([0017]-[0018]; [0022]; [0028]-[0029]; [0032]). Regarding claim 8, Kovacic et al. discloses wherein the control circuitry electrically interposes the electrical interface and the actuator to control the electrical power to the actuator (figure 1, reference #3, 4, 5, 28; figure 2, reference #21, 222, 31, 32; ([0017]-[0018]; [0022]; [0028]-[0029]; [0032]). Regarding claim 9, Kovacic et al. discloses wherein the control circuitry is configured to control motion of the drive unit and motion of the actuator, wherein the motion control of the drive unit is at least partially independent of the motion control of the actuator (figure 1, reference #3, 4, 5, 28; [0022]; [0028]-[0029]; [0032]). Regarding claim 11, Kovacic et al. discloses wherein the electrical interface includes at least one conductive pad disposed on a front face of the second connection interface for electrical interaction with the attachment (figure 1, reference #25; figure 2, reference #21 and 22; [0028]). As stated above in the rejection to claim 1, the attachment and its subparts (the electrical component) are not positively recited structures of the claims, and therefore the limitations as recited in claim 12 which further limit the attachment are not positive structural limitations that are part of the claim. However, in order to further prosecution, Kovacic et al. discloses wherein the attachment includes an electrical contact point engaging the at least one conductive pad to establish the electrical interaction (figure 1, reference #35; figure 2, reference #31 and 32; [0028]; [0032]).

As stated above in the rejection to claim 14, the attachment and its subparts (the electrical component) are not positively recited structures of the claims, and therefore the limitations as recited in claim 14 which further limit the electrical component are not positive structural limitations that are part of the claim. However, in order to further prosecution, Kovacic et al. discloses wherein the electrical component includes an actuator ([0006]-[0007] (known kitchen tools have actuators that permit the tools to operate); [0017]-[0018]; [0022]; [0028]-[0029]; [0032]); and the operational circuitry includes control circuitry configured to control motion of the drive unit and motion of the actuator, wherein the motion control of the drive unit is at least partially independent of the motion control of the actuator (figure 1, reference #28; [0022]; [0028]-[0029]; [0032]).

As stated above in the rejection to claim 14, the attachment and its subparts (the electrical component) are not positively recited structures of the claims, and therefore the limitations as recited in claim 17 which further limit the attachment are not positive structural limitations that are part of the claim. However, in order to further prosecution, Kovacic et al. discloses wherein the attachment includes an electrical contact point engaging the at least one conductive pad to establish the electrical interaction (figure 1, reference #35; figure 2, reference #31 and 32; [0028]; [0032]). Regarding Claim 28, Kovacic et al. discloses A food processing apparatus (figure 1, reference #1), comprising: a mixing head (figure 1, reference #2 where numeral 2 is pointing) including: a connection interface configured to selectively receive a mixing tool (figure 1, reference #15 and 17); a hub configured to selectively receive an attachment (figure 1, reference #27 and 30; [0016]; [0028]); a drive unit disposed in the mixing head and configured to rotate the mixing tool via the connection interface (figure 1, reference #3; [0028]), wherein the attachment includes an electrical component (figure 2, reference #35) (it is noted that the limitation uses the term “configured” which only requires the hub be capable of receiving an attachment, and therefore does not require the structural limitation of the attachment and its subparts (an electrical component) as part of the limitations of the claim); operational circuitry communicatively coupled with the drive unit (figure 1, reference #4); and an electrical interface disposed on the hub providing electrical communication between the electrical component and the operational circuitry (figure 1, reference #25; [0028]). As stated above in the rejection to claim 18, the attachment and its subparts (the electrical component) are not positively recited structures of the claims, and therefore the limitations as recited in claim 19 which further limit the electrical component are not positive structural limitations that are part of the claim. However, in order to further prosecution, Kovacic et al. discloses wherein the electrical component includes an actuator ([0006]-[0007] (known kitchen tools have actuators that permit the tools to operate); [0017]-[0018]; [0022]; [0028]; [0032]); and the operational circuitry includes control circuitry configured to control motion of the drive unit and motion of the actuator, wherein the motion control of the drive unit is at least partially independent of the motion control of the actuator (figure 1, reference #28; [0022]; [0028]-[0029]; [0032]). Regarding claim 20, Kovacic et al. discloses wherein the connection interface is disposed on an underside of the mixing head (figure 1, reference #16) and the second connection interface is disposed on a front of the mixing head (figure 1, reference #30).
