We provide a
trademark support system suitable for selecting goods or services. [Solution] The
trademark support device 100 includes first to third
product selection processes. Users can select and use the functions related to the first to third
product selection processes from a menu. In the first to third
product selection processes, based on information from a common product
list, if the relevant product (service) is registered in the product
list, the corresponding product selection
checkbox is checked when the product (service) is displayed. This allows the user to select a product (service) from the display results obtained by the other functions, taking into account the product (service) obtained by one of the functions related to the first to third product selection processes.
