You generally cannot copyright a name alone
Copyright protects original creative works, not short names, titles, slogans, or phrases
Use trademark protection if you want to protect a name used for a brand, product, or service
Check whether the name is already in use before trying to protect it
Search trademark databases in your country
Search business registries and domain name availability
File a trademark application with the appropriate government office
Use the name consistently in commerce
Keep records showing first use of the name
Register related domain names and social media handles
Consult an intellectual property attorney for legal advice
