27.6.4 Trademarks

Trademarks are commercial source indicators, distinctive signs, words, phrases or symbols (including packaging) that identify certain goods or services produced or provided by a specific person or enterprise. Trademarks are especially important when consumers and producers are far away from one another. The brands for Barbie dolls, Lego building blocks, and Hot Wheels are all trademarks. Trademarks assist consumers with choosing (or avoiding) certain goods and services. Throughout most of the world, trademarks must be registered to be enforceable, and registrations must be renewed.
