Business name vs trade mark: what each one actually does

The difference between a business name, trade mark and domain—and why you may need all three.

A business name tells people who is trading. A trade mark can protect a brand for particular goods or services. A domain is the web address you are licensed to use. Registering one does not automatically give you the rights that come with the others.

Business name

You may need to register a business name if you trade under a name other than your own legal name. The register helps people see who is behind the business. ASIC's name check does not look for every possible conflict in the market.

Trade mark

A registered trade mark can give you legal rights for the goods or services it covers. IP Australia considers more than business-name availability, including how distinctive the mark is and whether earlier rights exist.

Domain name

A domain gives you the right to use a web address for a set period. An available domain does not give you business-name or trade mark rights. Australian domains can also require proof that you meet the eligibility rules.

What to do before launch

Check the business name, trade marks and domains, but treat each result separately. If you plan to invest heavily in the brand, ask an Australian trade marks professional to review the risk before you apply or spend a large amount.
