  • Patent number: 10742765
    Abstract: A device system includes a first server on a first network and a second server on a second network. The second server stores processing data transmitted from the first server in the second memory, in response to a request for processing the processing data from the electronic device, transmits the processing data to the electronic device, and stores, in the second memory, information indicating that the processing data has been processed in association with the processing data in response to reception of a notification indicating that the processing data has been processed from the electronic device. The first server determines whether the second server stores the information indicating that the processing data has been processed, and stores the information indicating that the processing data has been processed in the first memory based on a determination that the second server stores the information indicating that the processing data has been processed.
