In Australia, legal protections exist for both registered and unregistered trade marks. As such the choice of whether to invest in the formal registration of a trade mark is one that many businesses weigh-up or often delay.
Ultimately, while opting not to register a trade mark does not leave you entirely without protection from infringement, registration offers far greater safeguarding of your valuable intellectual property. Registration of your trade mark does offer the security in the knowledge that you can safely continue to use your brand as having a registered trade mark is a defence to any alleged infringement.
In this guide, we will touch on the key differences between registered and unregistered trade marks from a legal standpoint and answer some common queries related to these.
How Well Protected Is Your Trademark?
Below, we have compared the legal protections available to both registered and unregistered trade marks to highlight the importance of registration.
|
Aspect |
Registered Trademarks |
Unregistered Trademarks |
|
Legal Basis for Protection |
Protected under the Trade Marks Act 1995 |
Protected under Common Law rights, and Australian Consumer Law (ACL) |
|
Ease of Enforcement |
Easier to enforce, as registration provides legal ownership and a presumption of exclusive rights to the mark |
Harder to enforce, as proof of reputation and misleading conduct is required for protection |
|
Burden of Proof |
Lower; the registration certificate is sufficient proof of ownership and exclusive rights to the mark |
Higher; must prove that the unregistered mark has developed a reputation in the relevant market and that misuse is likely to cause confusion or deceive consumers |
|
Scope of Protection |
Nationwide protection regardless of actual market presence in all areas |
Limited to areas where reputation and goodwill have been established |
|
Presumption of Ownership |
Registered owner has immediate presumption of ownership over the trade mark in relevant classes |
No presumption of ownership; must demonstrate goodwill or reputation, which can be challenging, expensive and time-consuming |
|
Infringement Actions |
Clear infringement action available under the Trade Marks Act against unauthorised use of an identical or deceptively similar mark |
Legal actions are complex, relying on passing off or misleading and deceptive conduct under the ACL, which may be harder to prove. Significantly more expensive. |
|
Available Legal Remedies |
– Injunctions to stop the infringer from using the mark – Damages for financial loss due to infringement – Account of Profits to recover profits earned by the infringer – Seizure of counterfeit goods |
– Injunctions to prevent further misuse of the mark – Damages for financial losses, though harder to quantify and prove – Account of Profits may be possible but is often challenging to establish |
|
Proof of Confusion or Deception |
Presumed based on similarity to registered mark within the same category; does not require evidence of actual confusion |
Must prove that the unregistered mark’s reputation has been misappropriated and is likely to mislead consumers or cause confusion |
|
Protection from Copycats and Infringement |
Strong protection; can enforce rights against copycats and prevent registration of similar marks by others. Recognised by platforms such as Amazon and eBay, to make takedowns easier. |
Limited protection; harder to prevent others from using a similar mark without proving a reputation and likelihood of confusion |
|
Potential Costs of Enforcement |
Typically lower, as registration provides a strong basis for legal action and minimises the need for additional evidence |
Often higher, as litigation requires extensive evidence to prove goodwill, market reputation, and actual confusion or deception |
|
Duration and Renewal |
Renewable indefinitely every 10 years, with protection as long as the trade mark is in use and maintained |
No formal duration or renewal; protection lasts as long as the mark is in use and maintains goodwill in the market but requires ongoing effort to establish and protect |
|
Ability to License or Sell |
Fully transferable and licensable, adding value to the business through monetisation and legal recognition |
Transfer or licensing is more challenging and may require additional documentation to prove market reputation and goodwill |
|
International Recognition |
Can be extended internationally via the Madrid Protocol system, making it easier to obtain global protection |
Difficult to enforce internationally; may need to establish reputation separately in each country for protection |

Frequently Asked Questions
Can You Infringe An Unregistered Trade Mark?
Yes, even though a trade mark may not be formally registered, it is still possible to infringe it. Registration is not what determines whether infringement has occurred or whether it is permitted.
Any use of a known logo, symbol or phrase that belongs to another business and is actively used by them in the promotion of their business could still be protected, whether registered or not. You can still face consequences for using an unregistered trade mark without the express permission of the owner.
However, it can be much harder for the original user to prove ownership if they have not registered their trade mark and as a result defending it against misuse is also more challenging and much more expensive.
Ultimately, the best course of action is to not utilise a trade mark that is the same or deceptively similar to one that is already in use, whether registered or not.
Can You Perform An Unregistered Trademark Search
While it is much more difficult to search for unregistered trade marks given there is no database for these, it is not impossible.
Tools such as reverse image search on Google can help you locate similar or identical trade marks to one you hope to use.
Even the simple act of searching for businesses offering similar goods and services can help you locate and determine whether your trade mark is unique enough in comparison to others already in use.
Remember, when it comes to defending against a possible trade mark infringement you will need to show that you did your due diligence in seeking out any possible risks for infringement. Always do a detailed search to avoid complications down the line. When it comes to due diligence, having an attorney perform an infringement search and providing a written and documented search report is the best option.
What Does A Trademark Symbol In Australia Look Like?
Registered trade marks can be denoted through the use of either the ™ symbol or the ® symbol.
The latter indicates that the trade mark has been properly registered with an appropriate governing body, is fully protected and is only for the exclusive use of the owner of that trade mark.
Is There An Unregistered Trademark Symbol?
Yes, unregistered trade marks such as logos, phrases, images or similar are permitted to use the ™ symbol.
This helps to indicate that they are in fact being treated as trade marks even if the formal registration process has not been undertaken. Unregistered trade marks may not use the ® symbol.
What Is A Registered Trademark Example?
Well-known registered trade marks include the McDonald’s Golden Arches, this is also an example of a series trade mark where associated phrases and symbols are included. The tagline ‘I’m lovin it’ that is used in much of McDonald’s advertising is also trade marked.
Google’s word trade mark is also quite well known. The blue, yellow, red and green colours used in the logo and their arrangement within the word also make up part of the trade mark specifications.
Likewise, the specific font used in Coca-Cola’s packaging is trade marked for their exclusive use and even the colour purple used by confectionary giants Cadbury is protected as a component of their trade mark.
