In general, trademark protection prevents another firm from using the same or a similar name, logo, or other identifying characteristics in a way that would cause confusion in the minds of potential buyers.
Firms and organisations need to register their companies as this helps them to avoid any problem related to the company's name and trademark in the future. Furthermore, trademark protection prevents another firm to copy another firms name, logo or tagline which can create confusion in the minds of potential buyers. Trademark protection costs a very minimal amount but protects a company's name.
