A registered trademark grants its owner exclusive rights to commercially use a brand name or logo in jurisdictions where it's registered and within specific goods and services. It also provides legal grounds to prevent others from infringing on those rights.
Protection applies not only to identical copies but also to marks that give a confusingly similar impression, which prevents competitors from launching brands that mislead consumers about the source of goods or services.
The main benefits of registration include being able to use the ® symbol, oppose similar applications at the IP office, report infringement on platforms such as Amazon, issue cease and desist letters, and pursue legal action against infringers. For e-commerce businesses, trademark registration is also a requirement for accessing Amazon Brand Registry.
