In order to protect the name of a business, it needs to be trademarked. Trademarks protect words, names, symbols, sounds or colours that distinguish the good and services of a business.
Before you can trademark your business name you need to check whether someone has beaten you to it. To do that visit the CIPC website and search its database to determine whether the name is available.
Once you are certain that the name has not already been registered, hire an attorney who specialises in trademarks to conduct a more extensive search before making a claim on the trademark. From there, you can go back to Cipro for forms and instructions for registering your business name.
