Final answer:
The correct term for a protected identification symbol for a product or service that has been registered is a 'registered trademark.' Notable examples are Chiquita bananas and the Nike swoosh. These can be renewed as long as they remain in use.
Step-by-step explanation:
A word, phrase, logo, shape, or sound that has been examined, approved, and registered with the trademark office is called a registered trademark. Trademarks are a legal means to protect the identifiers of products or services that a consumer can recognize.
They are granted based on the unique form and style, rather than the idea itself, to protect the interests of businesses and prevent consumer confusion. Notable examples include the name 'Chiquita' for bananas, the 'Chevrolet' brand for cars, or the notable Nike 'swoosh' on athletic gear. Millions of trademarks are registered with governments around the world, and they can be renewed indefinitely, as long as they are in active use.
