Abstract
Some non-Net companies, so called "clicks-and-mortal", now use the Net effectively, so that they use traditional sales channels or transform those to survive. They use ASP effectively, sometimes strategically. In particular, lock-in strategies using ASP are found in BtoBtoC business environment. Those systems have begun to provide Web-service interface. Then, this paper focuses on common system-infrastructures of each industry, and clarifies the future issues to be addressed. In this paper, not only business trends but also business-method patents are studied.
