Legal Definitions - proprietary name

A proprietary name is a word or phrase that identifies or designates a specific product or service and distinguishes it from others. It is a name that is owned and registered as a trademark, and cannot be used by other companies without permission.

• Coca-Cola is a proprietary name for a soft drink.
• iPhone is a proprietary name for a smartphone.
• Advil is a proprietary name for a pain reliever.

These examples illustrate how each name is unique and specific to the product or service it represents. No other company can use these names without infringing on the trademark owner's rights.
