Patent number: 7437315Abstract: This disclosure relates to a method and apparatus for implementing online sales in an environment on a network, which is provided by a creator, without putting any load on the creator. A creator-side apparatus transmits a content that forms merchandise and merchandise information about its output medium to a support-side apparatus. The support-side apparatus makes the merchandise information correspond to an address that indicates a location on the network and transmits the address to the creator-side apparatus as an address where an order for the merchandise should be received. The creator-side apparatus sends data containing the address to the network to which an orderer-side apparatus is connected such that the orderer-side apparatus accepts connection to the location. The support-side apparatus executes merchandise order reception processing when the orderer-side apparatus is connected to the location and requests an output system to execute output processing based on the merchandise information.Type: GrantFiled: May 3, 2004Date of Patent: October 14, 2008Assignee: Canon Kabushiki KaishaInventors: Yutaka Myoki, Shinichi Suzuki, Kikuo Naito, Miwa Takagi, Masanori Saito, Tomoko Eguchi
