If you run an online business, you’ve probably made something with AI this week, a logo concept in Midjourney, a hero image in DALL·E or Adobe Firefly, some website copy with ChatGPT or Claude. Which raises a question most founders never stop to ask until something goes wrong: do I actually own this, and how do I protect it?

The answer depends on which kind of protection you mean. Copyright and trade mark are two completely different tools that people constantly mix up. Getting them straight is the difference between protecting your brand and assuming you’re covered when you’re not, especially once AI is in the mix.

The one-line difference

Copyright protects creative works. A trade mark protects brand identifiers.

Copyright is about the thing you made, an image, an article, a photograph, a song, a video. A trade mark is about the badge that tells customers it’s you, your business name, your logo, your product names, your tagline.

Your blog post is protected (if at all) by copyright. Your business name at the top of that blog is protected by trade mark. Same website, two different legal systems.

How each one works in Australia

Copyright is automatic. In Australia there’s no register and no application, copyright exists the moment an original work is created in a material form, and it lasts for decades. You don’t do anything to “get” it. The catch, as we’ll see, is that AI complicates whether copyright exists at all.

Trade marks are the opposite. They’re not automatic. You apply to IP Australia, your mark is examined, and once registered you get exclusive rights for 10 years (renewable) across the classes you registered. That registration is what gives you a clean, enforceable right to stop others using your brand.

So one is free and automatic but limited; the other takes an application and a fee but gives you a much stronger, clearer claim over the thing that matters most, your brand.

Where AI throws a spanner in the works

Here’s the twist that catches creators out. In Australia, copyright generally requires a human author. A work needs human creative input to be protected. When you type a prompt and an AI tool spits out an image, it’s genuinely unclear how much copyright, if any, sits in the raw output, and who would own it.

That means the image Midjourney or DALL·E generated for you may have weak or uncertain copyright protection. If a competitor copies it, your ability to stop them under copyright law is murky at best. (We dig into this in our article on whether you can copyright something AI made.)

Now look at what doesn’t have that problem: your trade mark. Trade mark protection doesn’t care whether a human or an AI drew your logo. It protects the logo as a badge of origin, a signal that this brand is yours. So even where AI weakens your copyright position, a registered trade mark gives you a solid, separate right over your brand identity that doesn’t depend on who (or what) created the artwork.

This is the key insight for anyone building a brand with AI tools: copyright over your AI-made assets may be shaky, but a trade mark over your brand is rock solid, if you register it.

A quick worked example

Say you launch a candle brand. You use ChatGPT to brainstorm the name “Emberline”. You use Midjourney to generate the logo. You use Firefly for your product photography backdrops.

• The name “Emberline”, protect it with a trade mark. Registration gives you exclusive rights to use it for candles and related goods, and lets you stop copycats.
• The logo, protect the brand identity with a trade mark (you can register a logo). Copyright in the AI-generated artwork itself may be uncertain, which is exactly why the trade mark matters.
• The product images, copyright might protect them, but if they’re purely AI-generated, don’t count on it. They’re marketing assets, not your core brand, so the stakes are lower.

Notice the pattern: for the things that are your brand, the name and the logo, trade mark is doing the heavy lifting. Copyright is a nice-to-have that AI has made unreliable.

Which one do you actually need?

For most online businesses, the honest answer is both, but trade mark is the one you must be deliberate about.

Copyright you get for free, so there’s nothing to “do” except keep records of what you created and when. Trade mark you have to actively secure, and it’s the protection that stops another business trading off your name, your logo and the reputation you’ve built. Because it requires an application, it’s also the one people put off. And because AI has muddied copyright, it’s now more important than ever that your brand identifiers are locked down the one way that isn’t muddy: registration.

The bottom line

Copyright protects what you make; trade mark protects who you are in the market. AI has made copyright over your creative assets uncertain, but it’s changed nothing about the strength of a registered trade mark. If you’re building a brand with AI tools, the smartest move is to stop relying on shaky copyright over AI outputs and start protecting the parts that matter most, your name and your logo, with a trade mark.

and lock down your brand properly.

Frequently asked questions

What’s the difference between copyright and a trade mark? Copyright protects original creative works (images, writing, music) automatically. A trade mark protects brand identifiers (your name, logo, tagline) and must be registered with IP Australia to give you exclusive, enforceable rights.

Do I own the copyright in an image I made with Midjourney or DALL·E? It’s uncertain. Australian copyright generally requires a human author, so purely AI-generated images may have weak or no copyright protection. This is a key reason to protect your brand identity with a trade mark instead of relying on copyright.

Can I trade mark a logo that AI created? Yes, you can register an AI-generated logo as a trade mark, because trade mark protection is about the logo’s role as a badge of origin, not about who created it. A clearance search first is still essential.

If copyright is automatic and free, why bother with a trade mark? Because copyright doesn’t protect your business name, and AI has made copyright over creative asset
