doing business in state

A foreign corporation is doing, transacting, engaging in, or carrying on, business in the state when, and ordinarily only when, it has entered the state through its agents and is there engaged in transacting through them some substantial part of its ordinary or customary business, usually continuous in the sense that it may be distinguished from merely casual, sporadic, or occasional transactions and isolated acts. 36 Am J2d For Corp § 317. A combination of acts or transactions may constitute doing business, where neither of the acts or transactions taken separately amounts to doing business. 29 Am J Rev ed Ins § 68. A foreign corporation may safely be said to be doing business wherever an important combination of functions is being performed, such as the ownership, possession, or control of property, dealing with others in reference to the property, the exercise of discretion, the making of business decisions, the execution of contracts, the marketing of a product by advertising and solicitation, and collecting for the sold product. 36 Am J2d For Corp § 319.
