Conclusion

APPLICANT REBUTTAL: REMARKSClaims 1-20 are pending in the present application including independent claims 1 and 13. Claims 1 and 13 are currently amended. Claims 9-10 and 19 are hereby canceled without prejudice. Applicants respectfully request reconsideration and allowance in view of the amendments to the claims and the following remarks.Claim Reiections - 35 U.S.C. § 103 Claims 1-2, 4-14, and 16-20 are rejected under 35 U.S.C. § 103 as being unpatentable over Kim (US 2020/0071871) in view of Gallagher (US 2017/0037559). Claims 3 and 15 are rejected under 35 U.S.C. § 103 as being unpatentable over Kim in view of Gallagher, and further in view of Ha (US 2021/0025104). These rejections are respectfully traversed. In this regard, Applicant respectfully submits that these claims are not obvious for at least the reason that the proffered combinations do not yield the claimed invention.Independent claim 1 has been amended to recite that the camera assembly is mounted to face the discharge nozzle to monitor the flow of wash fluid before the wash fluid reaches the load of clothes. The new limitations include no new matter and are fully supported by the specification and the drawings of the present application. See, e.g., ¶¶ [0057] and FIGS. 6-7.Notably, these limitations were also recited at least in part in dependent claim 9-10 (now canceled). Applicant respectfully submits that the cited references fail to teach, disclose, or suggest such limitations and that this claim is currently in condition for allowance.In this regard, in rejecting prior claim 9, the Office Action cites Kim as teaching an image sensor for monitoring the flow of wash fluid, referring to paragraph [0055]. Office Action page 7. However, Applicant respectfully notes that Kim teaches the use of image sensor 322 to monitor the internal glass of the door. Kim, ¶ [0118]. In addition, Kim teaches the use of a detergent bubble recognizer 110 to determine when a rinse cycle can be terminated or when additional rinses should be performed. Kim, ¶ [0098]. Notably, monitoring the discharge nozzle or the flow of the wash fluid only-i.e., before it interacts with the load of clothes-would defeat the purpose of Kim, which requires agitation and rinsing with fresh water to determine how much detergent remains in the clothes. Accordingly, Applicant respectfully submits that claim 1, as amended, is patentable over the cited references.In view of the above, the Examiner is respectfully requested to reconsider the rejection of independent claim 1. Applicant respectfully submits that the cited references fail to teach all limitations of independent claim 1 and that this claim patentably defines over the cited references. The Office Action rejected independent claim 13 on the same grounds and based upon the same authority as claim 1. Notably, independent claim 13 has been amended to include similar limitations as claim 1. Thus, for the same reasons as discussed with respect to claim 1, Applicant respectfully submits that claim 13 is patentable over the cited references.Consequently, it is respectfully submitted that independent claims 1 and 13 are in condition for allowance.Applicant also respectfully submits that for at least the reasons indicated above relating to independent claims 1 and 13, the corresponding dependent claims are also in condition for allowance. However, Applicant also notes that the patentability of corresponding dependent claims certainly does not hinge on the patentability of the independent claims. In particular, it is believed that some or all of these other claims may possess features that are independently patentable, regardless of the patentability of the independent claims. In summary, it is respectfully submitted that the present application is in complete condition for allowance and favorable action is therefore respectfully requested.Conclusion With the present submission, Applicant respectfully submits that all pending claims are allowable, and that the application is in condition for allowance. Favorable action thereon is respectfully requested. The Examiner is encouraged to contact the undersigned if there are any questions regarding this matter or if any additional information is required. If any fee not accounted for above is required for entry of this Response or papers filed herewith, authorization is hereby granted to charge such fee to Deposit Account No. 04-1403. If any petition is required for entry, such petition is hereby made and any associated fees may also be charged to our deposit account.[SIGNATURE BLOCK ON FOLLOWING PAGE]Respectfully submitted, DORITY & MANNING, P.A.March 18, 2025
