What does “use” of a Trademark Mean?

A trademark is used on goods when the mark appears on the goods, or packaging or labeling for the goods, and the goods are sold in the normal course of trade. A trademark is not used on goods when it appears in advertisements for the goods or if the sale of the goods is an isolated one or if they are distributed free.
A trademark is used on services, for example restaurants, retail stores, construction contractors or musical bands, when the mark appears in advertisements or promotional material for the services and such services are actually available at that time.
