What is the difference between a brand name and a generic drug?

The distinction between a brand name and a generic drug primarily revolves around trademarking and branding. A brand name drug is typically developed and marketed by a specific pharmaceutical company, which holds a trademark on its name to distinguish it from other products. This trademark allows the company to have a unique identity and brand recognition in the marketplace.

On the other hand, generic drugs contain the same active ingredients as their brand-name counterparts but are marketed under their chemical names or assigned names without the brand's trademark. Once the patent for a brand-name drug expires, other manufacturers can produce and sell the generic version, making it available under a non-brand name.

While there are other differences involving pricing, availability, and formulation, the key focus in this question is the trademark aspect, making the correct choice highlight the legal status of branding in pharmaceuticals.
