What is a trademark?

A trademark is a sign you use to distinguish your goods or services from everyone else’s. Lawyers call it a “badge of origin”, because its job is to tell customers that a product or service comes from you and not from a competitor. When someone sees your brand on a label, a shopfront or a website, the trademark is what links that product back to your business and your reputation.

In Australia, trademarks are governed by the Trade Marks Act 1995 and administered by IP Australia. The legal definition of a “sign” is deliberately broad, which is why so many different things can be protected as a trademark.

What a registered trademark gives you

Registration turns your brand into a piece of property you genuinely own. Specifically, it gives you:

• An exclusive, Australia-wide right to use the mark for the goods and services you register it for.
• The right to licence the mark to others or sell it as a business asset.
• The ability to take legal action for infringement if someone uses a similar mark on similar goods or services, including seeking injunctions and damages.
• A public record on the trademarks register that deters copycats before they start.
• A foundation for protecting your brand overseas, since your Australian filing date can anchor a 6-month priority window in other countries.

Without registration you fall back on “passing off” and the Australian Consumer Law. Both can work, but they are reactive, expensive, and you have to prove your reputation from scratch each time. Registration flips that around: the right is already on the public record, so enforcement is far simpler and cheaper.

What can be a trademark

The word “sign” covers far more than a name or logo. Any of the following can, in principle, be registered if it distinguishes your goods or services:

Type	Example
Word or phrase	A brand name, a made-up word, or a slogan in plain font
Logo or device	A symbol, graphic or stylised design, with or without words
Combined mark	A name and logo locked up together as one image
Shape	A distinctive 3D product or packaging shape
Colour	A single colour used consistently across a brand
Sound	A jingle or audio signature
Scent	A distinctive smell that is not the product’s natural odour

Word marks usually give the broadest protection because they cover the name in any font or styling. Many businesses register the word and the logo separately so that a future rebrand or redesign does not leave the name exposed.

What can be hard to register

Not every sign qualifies. The most common reasons an application runs into trouble are:

• Descriptive or generic words. A mark that simply describes the product, its quality or its location is hard to register because other traders have a legitimate need to use those words. “Fresh Bread” for a bakery is a weak choice; an invented word is far stronger.
• Common surnames and geographic names. These can be registered, but often only with evidence that the public already associates them with you.
• Conflict with an earlier mark. If your sign is substantially identical or deceptively similar to a mark already registered for similar goods or services, it can be refused.
• Prohibited or scandalous signs. Flags, official emblems, certain protected words, and offensive content are barred.

The strongest, easiest marks are invented or arbitrary words that have no obvious link to the product. Think of a coined name that means nothing until your brand gives it meaning. You can sense-check availability early with our free trademark search.

Trademark vs business name vs company name vs domain

This is the single most common and costly misunderstanding we see. Registering a business name or company name with ASIC, or buying a domain, does not give you ownership of your brand.

What it is	What it actually does	Brand ownership?
Business name (ASIC)	Lets you trade under a name	No
Company name (ASIC)	Creates a legal company	No
Domain name	Reserves a web address	No
Registered trademark	Exclusive legal right to the brand	Yes

ASIC registration is administrative. It does not stop someone else trademarking that name, and it does not protect you if your name infringes an existing trademark. You can hold the business name and still be told to stop using it by a trademark owner. We explain this gap in detail in our guide on business names vs trademarks, and you can line up your web address with your brand using our domain check tool.

™ vs ®

• ™ can be used by anyone to flag that they are treating something as a trademark, whether or not it is registered. It is a notice, not a legal status.
• ® means the mark is officially registered. Using ® on an unregistered mark in Australia is an offence, so only use it once registration comes through.

How long protection lasts

A registered trademark lasts 10 years from the filing date and can be renewed every 10 years, indefinitely. There is no point at which the law forces you to give up a brand you keep using and renewing. If a renewal is missed, there is a 6-month grace period with a $100 per month late fee before the registration lapses. There is more detail in our guide on how long a trademark lasts.

Common questions

Do I have to register to use a trademark? No. You can use the ™ symbol and build unregistered rights through reputation. But registration is the only way to get a clear, enforceable, Australia-wide right, and it is far cheaper to defend than unregistered rights.

Does registering my company name protect my brand? No. A company name and a trademark are different things. Only the trademark gives you the legal right to stop others using a similar brand.

Can I trademark a single word that describes what I do? Usually not on its own. Purely descriptive words are weak. Invented or distinctive words are much easier to protect, and a descriptive term can sometimes qualify later with proof that customers already associate it with you.

Do I need a lawyer or attorney? It is not required, and you can self-file. But mistakes such as the wrong classes or a poorly drafted description are often non-refundable, so professional help pays off, especially for searches and objections.
