While copyright refers to the exclusive right an author/artist holds over their original masterpieces to prevent them from getting pirated, Trademark refers to a company name, logo, design features, or taglines that make the brand exclusive and distinct. It sets the brand apart from similar ones in the market.
Copyrights and trademarks will help you to defend your ownership and challenge competitors legally in court in the event of duplication, where they have used your intellectual property without authorization.
