What term is used to describe a registered product's proprietary name given by its manufacturer?

The term used to describe a registered product's proprietary name given by its manufacturer is the brand name. This name is specifically crafted to distinguish the product from other similar products in the market and is protected under trademark laws. A brand name is vital for marketing and consumer recognition, allowing a manufacturer to build a reputation associated with quality, efficacy, or specific features of their product. While terms like trade name, common name, and formula name may also have relevance in different contexts, the brand name specifically refers to the unique name a company uses to promote and identify its product in a competitive environment.
