It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the washing machine of Hosomi with the external control of Chang to allow for a user to remotely operate the washing machine. Hosomi, per Chang, determining the laundry appliance idle time comprises recognizing a pattern of historical laundry appliance operations. However, McAllister teaches a washing machine and control scheme that discloses monitoring historical data points and usage of the washing machine (¶ 27-28). The resultant combination would be such that the historical data of the idle time of Hosomi would be monitored therefore disclosing that the memory includes an historical record of laundry appliance operations (Executed cycles per ¶ 28 of McAllister); and determining the laundry appliance idle time comprises recognizing a pattern of historical laundry appliance operations (Resultant combination). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the control of Hosomi’s washing machine with the historical data of McAllister to allow for a user and the a controller to monitor the operation of the washing machine and detect errors or better control future operations. Regarding claim 17, Hosomi’s modified teachings are described above in claim 16 where the combination of Hosomi, Chang, and McAllister would further disclose that the pattern of historical laundry appliance operations includes periods of time that the laundry appliance is idle (Resultant combination where the idle time is monitored by Hosomi and the McAllister would teach monitoring/storing the operations of the washing machine which would include idle times). Regarding claim 18, Hosomi’s modified teachings are described above in claim 16 where the combination of Hosomi, Chang, and McAllister would further disclose determining the laundry appliance idle time comprises user input at the external device (Resultant combination of the predetermined time of Hosomi to be able to input via the external device of Chang). Regarding claim 20, Hosomi’s modified teachings are described above in claim 16 where the combination of Hosomi, Chang, and McAllister would further disclose a user manipulation of one of the user input devices and the external device may interrupt the air dry mode (The user has the ability to pause the operation in Hosomi by interacting with the control panel in Figure 3). Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over WO 2008/117506 (Hosomi) in view of US 2020/0248386 (Islas) in view of US 2021/0017686 (Chang) and further in view of US 2020/0248356 (Kwon hereinafter). Regarding claim 9, Hosomi’s modified teachings are described above in claim 6 but are silent with respect that the network further comprises a user calendar including a laundry schedule; and wherein determining the laundry appliance idle time comprises use of laundry schedule information included in the laundry schedule. However, Kwon teaches a laundry control scheme that discloses a network further comprises a user calendar including a laundry schedule (¶ 10); and wherein determining the laundry appliance idle time comprises use of laundry schedule information included in the laundry schedule (Resultant combination for the schedule of Kwon to be a factor for the idle time calculations of Hosomi/Chang). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the control of Hosomi with the scheduling aspect of Kwon to allow for a user to set specific operation times for the washer which align with the user’s schedule. Claim 19 is rejected under 35 U.S.C. 103 as being unpatentable over WO 2008/117506 (Hosomi) in view of US 2020/0248386 (Islas) in view of US 2021/0017686 (Chang) in view of US 2010/0000023 (McAllister) and further in view of US 2020/0248356 (Kwon). Regarding claim 19, Hosomi’s modified teachings are described above in claim 16 but are silent with respect to determining the laundry appliance idle time comprises use of laundry schedule information included on a user calendar in the network memory. However, Kwon teaches a laundry control scheme that discloses determining the laundry appliance idle time comprises use of laundry schedule information included on a user calendar in the network memory (¶ 10). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the control of Hosomi with the scheduling aspect of Kwon to allow for a user to set specific operation times for the washer which align with the user’s schedule.
