Office Action

§103
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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 2/5/2026 has been entered. Response to Amendment By presentation of the most recent claim amendments filed 2/5/2026, the status of the claims is as follows: claims 1-2, 5-6, 9-10, 13, 15-20, 22, 25-26, 28, 34, 37-38, 43, 48-51, 57-59, and 62-64 are pending; claim 62 is withdrawn as being a non-elected claim (see Response to Restriction Requirement on 11/7/2024); claims 3-4, 7-8, 11-12, 14, 21, 23-24, 27, 29-33, 35-36, 39-42, 44-47, 52-56, and 60-61 are canceled; and claim 64 is new. Upon further search and consideration of Applicant’s remarks filed 2/5/2026, the claims are rejected over a combination of previously applied references and the addition of a new reference as discussed in detail below. 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. Claims 1-2, 5-6, 9-10, 13, 15-20, 22, 25-26, 28, 34, 37-38, 48-51, 57-59, 63-64 are rejected under 35 U.S.C. 103 as being unpatentable over Kloepfer et al. herein referred to as “Kloepfer” (USPPN 2017/0225203, previously cited on IDS filed 1/28/2022), and further in view of Fischer et al. herein referred to as “Fischer” (USPPN 2017/0232482). As to claim 1, Kloepfer discloses a high pressure cleaning system 10, comprising a high pressure cleaning appliance that has a pump assembly 14, at least one accessory that is in or can be brought into flow connection with a high pressure outlet of the pump assembly (para 80 and Fig 1: see variety of discharge devices 34, 48, 52, 56, 60, 64, 70, etc., wherein the high pressure cleaning appliance is operable with at least one variable operating parameter (paras 86-87: see different operating levels, for example), an input unit, at least one control unit coupled to the input unit, and an output unit coupled to the at least one control unit, See paras 117-119 for description of smart device 134, for example that is usable with the apparatus for controlling and communicating operation steps: [0117] Shown in FIG. 1 is an accessory device 132 as a further component of the high-pressure cleaning system. The accessory device, preferably a portable one, is for example a portable computer or a smartphone 134. The smartphone 134 can be used as an alternative or in addition to the integrated unit 102 or 124. The touch screen 138 can be used as an integrated input/output unit 136. An internal data processing device of the smartphone 134 can be used in lieu of the control unit 98. [0118] Where the smartphone 134 is used for predetermining at least one output parameter, input to and output from the touch screen 138 are realized for example as described above in the context of the example of FIG. 9 and the touch screen 128. [0119] In an advantageous embodiment, the control unit 98 and/or the internal control unit of the smartphone 134 can establish a wireless data connection over a communication network 140 (for example the Internet) with a spatially remote data processing device 142. To this end, the latter comprises for example a radio member 144 for communication with the radio member 112 or a radio member of the smartphone 134. wherein an object to be cleaned is specifiable by way of the input unit and a cleaning recommendation is providable on the output unit by the at least one control unit in dependence on the specification, said cleaning recommendation comprising an instruction for using at least one of an accessory and a value of at least one operating parameter, and wherein at least one interaction element is providable for the user, linked to the cleaning recommendation, on the output unit for transmitting interaction information to the at least one control unit, in dependence on the cleaning recommendation. At paras 119-125, for example, use of cleaning profiles are used in providing recommendations in addition to a detection unit in providing recommendations: [0119] In an advantageous embodiment, the control unit 98 and/or the internal control unit of the smartphone 134 can establish a wireless data connection over a communication network 140 (for example the Internet) with a spatially remote data processing device 142. To this end, the latter comprises for example a radio member 144 for communication with the radio member 112 or a radio member of the smartphone 134. [0120] The data processing device 142 is for example owned or administered by a manufacturer of the high-pressure cleaning system 10 and is coupled to a database 146. For example, the database 146 can have cleaning profiles stored therein. As used herein, this means in particular that the corresponding cleaning profile comprises a predetermination of a value or range of values of at least one output parameter. Data that comprise the definition of a cleaning profile can be transmitted over the communication network 140 to the control unit 98 or to the smartphone 134 and be stored in the storage unit 106 or in the storage device of the smartphone 134 respectively. Accordingly, the cleaning profile can be downloaded. For example, the cleaning profile further comprises a symbol 130 for presentation on the touch screen 128 or 138 respectively. [0121] As has been described above, the user can make a predetermination of at least one output parameter of the high-pressure cleaning apparatus 12 by selecting the corresponding symbol 130. [0122] Furthermore, the high-pressure cleaning system 10 may comprise a detection unit 148. The detection unit 148 is for example arranged on the gun 28 and coupled to the control unit 98 or to the data processing device of the smartphone 134. [0123] The detection unit 148 enables detection of which particular discharge unit is connected to the gun 28 or which of the discharge units of the discharge device 34 assumes the position of use. FIG. 8 schematically shows a discharge unit 150. [0124] If the discharge unit detected deviates from the discharge unit according to the indication 116, the user can be provided with a corresponding indication. By way of example, an indication is presented on the output unit 100. It is also possible for the high-pressure cleaning apparatus 12 and/or the gun 28 to inhibit the discharge of cleaning liquid until a discharge unit in conformance with the indication 116 has been connected to the gun 28 or selected. [0125] The detection unit 148 may detect the discharge unit by contact or non-contact techniques, using for example mechanical, electrical or other types of techniques. By way of example, contactless detection occurs by RFID technology. Kloepfer discloses providing at least three operating levels, i.e. levels 1, 2, and 3, along with corresponding items each level is useful in cleaning via pictogram, i.e. garden fence for level 1, motor vehicle for level 2, brickwork for level 3, etc. (see paras 82-85), as well as intermediate levels 1.5, 2.5, etc. (para 95). User receive guidance from buttons 90, 92, 94 (Fig. 4; para 96) in order to select the appropriate operating level. Further in Kloepfer, the detection of a deviation from the discharge unit triggers an indication to the user, in which the user can make a determination on how to proceed. These features essentially show a back and forth dialogue between the user and control features that relate to the cleaning recommendation of the proper tool being used and/or pressure level of cleaning. It is unclear whether a value of the operating parameter may be adjusted or reduced when it exceeds the cleaning recommendation in Kloepfer. However, in the art of pressure wash sprayers, Fischer discloses the known steps of providing a recommendation for the spray nozzle being dependent on the pressure of the admixed fluid, and further displaying the recommendation to the user on the display device to the user (para 41). For example, four different pressure ranges may be displayed to the user (Fischer at para 86). Control commands can be transmitted from the electric apparatus 202 to the high-pressure cleaning appliance for setting a specific pressure range, which the user can select on a display device 208, preferably on a liquid crystal display. On the display device 208 different cleaning parameter ranges can, for example, be displayed graphically to the user, from which the user can select a desired cleaning parameter range, for example, a specific pressure range. Additionally, other information can be displayed graphically on the display device 208. In particular, a recommendation for a certain spray nozzle which can be connected when there is a specific pressure of the fluid supplied to the spray gun 200 can be displayed graphically on the display device 208 to the user (Fischer at para 91). Fischer discloses known means for providing a communication between the user to the machine in a back and forth manner that provides live feedback. It would have been obvious to one having ordinary skill in the art at the time of the invention to incorporate this type of communication regarding a value of specific pressure in order to operate the apparatus of Kloepfer properly, prevent excessive pressure being applied on the article being cleaned which would cause damage to the article, or too little pressure being applied to the article being cleaned thus resulting in ineffective cleaning. As to claim 2, the cited prior art at Kloepfer discloses wherein the at least one interaction element is providable in the form of a button, a selection element, or a rotary or slide control on the output unit, wherein the output unit is a display unit on which the at least one interaction element is displayable (para 46: The input unit may comprise for example at least one switch, button, rotary knob, key or other type of operating element.) As to claim 5, the cited prior art at Kloepfer discloses wherein the at least one interaction element comprises a confirmation element by the actuation of which a confirmation information of the user is transmittable to the at least one control unit (para 47: touch screen, for example). As to claim 6, the cited prior art at Kloepfer discloses wherein the cleaning recommendation comprises an indication relating to the value of at least one operating parameter and wherein the high pressure cleaning appliance is settable to the value of the at least one operating parameter upon confirmation by the at least one interaction element (para 50: It proves advantageous for the input unit and/or the output unit and/or the control unit to be, at least in part, arranged on or comprised by the operating unit. This facilitates to the user the handling of the system by enabling him or her to enter inputs on the operating unit and/or to receive outputs at the operating unit.). As to claim 9, the cited prior art at Kloepfer discloses wherein a plurality of cleaning recommendations are providable connected to a respective at least one interaction element and wherein the cleaning recommendations comprise at least one instruction relating to the use of an accessory, wherein the accessories of different cleaning recommendations differ from one another, and wherein the respective at least one interaction element forms a confirmation element or a selection element, upon the actuation of which information for using the accessory linked to said interaction element is transmittable to the control unit (paras 65-66: [0065] An indication as to which discharge unit assumes the position of use in each case and which other two discharge units are in the position of non-use in each case is given to the user by indicia 40 provided on the housing 36, for example. The indicia 40 comprises an individual symbol associated with each discharge unit and easily visible to the user. In particular, the discharge device 34 comprises a high-pressure flat jet nozzle 42 for emitting a fan-shaped cleaning jet. The discharge device 34 further comprises a high-pressure rotary nozzle 44 through which a high-pressure pinpoint jet that rotates on the curved surface of a cone can be emitted. The discharge device 34 further comprises a low-pressure cleaning agent nozzle 46. The nozzle opening cross-sectional area of the cleaning agent nozzle 46 is substantially larger than the respective nozzle opening cross-sectional area of the flat jet nozzle 42 and the rotary nozzle 44. The cleaning agent nozzle 46 allows for emission of a high-volume flow rate cleaning jet under less pressure than with the two other nozzles 42, 44.). As to claim 10, the cited prior art at Kloepfer discloses wherein the high pressure cleaning appliance is settable to the value of the at least one operating parameter, even without prior confirmation or change by the user (see paras 35-38: a predetermined operating level may be automated).

Here, the arrow 178 symbolizes the discharge device 42 and the symbol 180 symbolizes the washing brush 56). As to claim 16, the cited prior art at Kloepfer discloses wherein the at least one interaction element comprises a request element, upon actuation of which by the user at least one cleaning instruction, in, for cleaning the object is providable on the output unit by the at least one control unit (para 124: If the discharge unit detected deviates from the discharge unit according to the indication 116, the user can be provided with a corresponding indication. By way of example, an indication is presented on the output unit 100. It is also possible for the high-pressure cleaning apparatus 12 and/or the gun 28 to inhibit the discharge of cleaning liquid until a discharge unit in conformance with the indication 116 has been connected to the gun 28 or selected.). As to claims 17-18, the cited prior art at Kloepfer discloses wherein successive cleaning instructions are providable on the output unit in the form of a step-by-step guide for the user for cleaning the object, and wherein the cleaning instructions are providable for the user with respective interaction elements, wherein the cleaning instruction according to the subsequent step of the guide is providable upon actuation of an interaction element (paras 113-114 for examples of multi-step instructions and user input).

The user can thereby be alerted to check the choice of the output unit.). As to claims 63-64, see analysis above to overlapping claim features in prior claims. 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. Claim(s) 43 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kloepfer and Fischer as applied to claims above, and further in view of Knutson et al. herein referred to as “Knutson” (USPN 2017/0049288, previously cited on IDS filed 3/15/2022). As to claim 43, Kloepfer and Fischer are silent regarding use of a camera as the detection means and therefore is silent regarding “wherein the detection unit comprises a camera for creating at least one image of the object and image information relating thereto is transmittable to the at least one control unit, and wherein the control unit is configured to determine the object on the basis of the image information”. Even though Kloepfer is silent regarding use of a camera, Kloepfer does disclose use of a smartphone as a control unit for both input and output of information (para 52 of Kloepfer). Use of a camera is known in the art of smartphone controlled cleaning apparatus, as taught by Knutson’s use of a handheld computing device or phone to communicate information to the operator regarding the cleaning operation by having taken photos using a camera on the machine (para 63 of Knutson). Use of cameras in particular are helpful to for object recognition to be used in comparing to a reference image (para 36) or to view or visually determine the presence of dirt after cleaning (para 35 of Knutson). It would have been obvious to one having ordinary skill in the art at the time of the invention to incorporate use of a camera in the cited prior art, as taught by Knutson, as such use allows for object recognition in identifying the type of article being cleaned, and assessing the efficacy of cleaning by visually tracking remaining dirt. Response to Arguments Applicant's arguments filed 2/5/2026 have been fully considered but they are not persuasive. Primarily, Applicant contests that the applied prior art reference Kloepfer fails to teach each of the claim features of claims with respect to the newly added features of claim 1 regarding the control unit determining whether at least one of the value of at least one operating parameter deviates from the cleaning recommendation. The application of the Fischer reference addresses these features, as noted in detail above. As noted in the prior Office Action, the specific type of “operating parameter” is not disclosed in at least claim 1, thus making it unclear whether the parameter refers to the spraying pressure, the nozzle head selection, etc. Nonetheless, the Fischer reference discloses displaying adjustment of the spraying pressure, among other features, as discussed above.
