Who Is This Service For?

Lazarus Legal’s trademark lawyer Sydney team provides trademark search, registration and enforcement services to business owners and startup founders who want to protect their brand as a commercial asset. We act for clients across a range of industries, including:

If your name, logo or product identity carries value, it is worth protecting properly. Whether you are filing your first application or defending a mark you have spent years building, we help you secure and enforce your rights without the guesswork.

How Our Trademark Lawyers Help Sydney Businesses

Most brand problems are cheaper to prevent than to fix. Our trademark lawyers help Sydney businesses clear and register new marks, enforce their rights when someone crosses the line, and protect their brand as they grow into new markets.

Trademark Search and Registration

Before you invest in a name, you need to know it is clear to use and register. We run a comprehensive search of the IP Australia register and common law rights, then advise on registrability, the right classes, and any risks worth flagging early.

Example Scenario

You have spent nine months and a solid chunk of your seed round building a fintech brand out of your Barangaroo office. There is a logo, a live domain, printed collateral, and a launch date locked in.

A week out, your designer mentions seeing a similar name on another product. You check, and there it is on the IP Australia register, in the exact class you were about to file in, owned by a business you have never heard of. Now you are weighing a rushed rebrand against the risk of an infringement notice landing on launch day.

What We Do

We assess how close the two marks actually are, comparing them for visual, phonetic and conceptual similarity across the relevant class, then advise whether you can proceed, whether coexistence is realistic, or whether the risk is too high to file as planned.

If a change is needed, we map your options, from adjusting the mark to narrowing the specification of goods and services, and file a repositioned application in the correct classes, managing any examination or opposition that follows.

When someone trades on your reputation, or accuses you of trading on theirs, you need a clear head and a firm response. We handle cease and desist correspondence, oppositions, negotiated resolutions, and litigation where it becomes necessary.

Example Scenario

You have spent years building a hospitality group in Surry Hills, and the name is now the reason people book. Then a new venue opens a few suburbs over, trading under something almost identical, same feel, same crowd.

Reviews meant for them start appearing on your page, a supplier double-books thinking you are one business, and a regular asks why you have “opened a second spot” you have never heard of. Every week you leave it, the confusion grows and the other name digs in.

What We Do

We assess the strength of your position, weighing your registration and reputation against how the other party is using the name, then put them on notice with correspondence that sets out your rights and what you expect them to do.

From there we choose the enforcement path that fits your commercial goals, whether that is a negotiated resolution, a formal opposition, or litigation if it comes to that, and manage the matter through to a result that protects your goodwill.

If you sell across borders, an Australian registration alone will not cover you. We coordinate international protection so your brand is defended in the markets that matter to your growth.

Example Scenario

Your e-commerce label runs out of Alexandria, and orders from the United States and the United Kingdom have quietly grown from a trickle to a real slice of revenue. Then a marketplace listing appears overseas using your name on products that are not yours.

When you go to act, you learn your mark is only registered in Australia. The platform wants a local registration before it will take the listing down, and a rushed foreign filing now means waiting months while the counterfeit keeps selling.

What We Do

We map where you actually need protection, prioritising the jurisdictions tied to your revenue rather than filing everywhere at once, then file through the Madrid Protocol where it suits and coordinate with foreign associates for direct national filings where it does not.

From there we manage your filing deadlines and priority dates and keep the international portfolio organised as you expand, so protection stays ahead of where you are selling rather than catching up to it.
