You typed “give me 20 names for my coaching business” into ChatGPT, Claude or Gemini, and out came a shortlist that sounded perfect. Punchy. Available-looking. Ready to go on the logo.

Here’s the part the chatbot didn’t mention: a name that sounds great is not the same as a name you can legally own. And in Australia, owning your brand means one thing, a registered trade mark. Before you print the business cards, it’s worth understanding why an AI-generated name can quietly set you up for a knockback at IP Australia, or worse, a fight with someone who got there first.

Why AI loves names you can’t protect

To register a trade mark in Australia, your brand needs to be distinctive. That’s the whole point of the system, a trade mark is a badge that tells customers this product comes from this business and no other. The law (the Trade Marks Act 1995) won’t let one business monopolise words that everyone in an industry needs to use.

The trouble is that AI language models are built to produce the most likely, most natural-sounding answer. Ask for a name for a skincare brand and you’ll get “Glow”, “Pure”, “Radiance”, “Luxe”. Ask for a bookkeeping business and you’ll get “Balance”, “Ledger”, “Clarity”. These feel like brand names, but they’re often descriptive or laudatory, they describe the product or praise it, and those are exactly the words IP Australia is most likely to reject under section 41 for not being distinctive enough.

So the AI is optimising for “sounds like a real brand”, while the trade mark system is optimising for “is different enough to belong to only you”. Those two goals pull in opposite directions.

The name might already be taken (and AI can’t reliably tell you)

The second problem is bigger. Even a distinctive, invented name is worthless to you if someone else already holds it for similar goods or services. Your application can be blocked under section 44 if it’s deceptively similar to an earlier trade mark, not identical, just close enough that customers might be confused.

An AI chatbot has no live view of the Australian Trade Marks Register. It can’t run a proper search, it doesn’t assess “deceptive similarity” the way an examiner does, and it will happily invent a confident answer that turns out to be wrong. We cover exactly why that fails in our companion article on AI trade mark searches, but the short version is: an AI telling you a name “looks available” is not clearance. It’s a guess dressed up as an answer.

What “distinctive” actually looks like

The names that sail through are the ones that are made-up, unexpected, or use a familiar word in a way that has nothing to do with what you sell. Think of coined words, or an ordinary word applied to an unrelated product. The more your name describes what you do, the harder it is to protect. The more arbitrary or invented it is, the stronger it is.

This is genuinely good news for anyone using AI to brainstorm. The tools are brilliant at generating volume, dozens of options in seconds. You just can’t let the chatbot be the judge of which ones are legally strong. That’s a filter you (or your lawyer) apply afterward.

A smarter way to use AI when naming your business

You don’t have to swear off the tools. Use them for what they’re good at, and add the legal filter yourself:

1. Brainstorm widely. Let ChatGPT, Claude or Gemini throw out 30 to 50 options. More is better at this stage.
2. Cut the descriptive ones. Delete anything that plainly describes your product, praises it, or is a common industry term. If a competitor would reasonably want to use the same word, drop it.
3. Favour the invented and the arbitrary. Shortlist the coined words and the surprising combinations. These are your registrable candidates.
4. Get a proper clearance search. Before you commit, before the domain, the logo, the launch, have the shortlist checked against the Register for real.
5. File early. In Australia, trade mark rights broadly go to the first to apply. If you love it, protect it before someone else does.

Why this matters more in the AI era, not less

Here’s the uncomfortable bit. Thousands of founders are using the same handful of AI tools, trained on the same data, and getting similar suggestions. That means more businesses are landing on near-identical names at the same time, and the Register is filling up faster with lookalikes. The name the chatbot gave you this morning may be the same name it gave three other people this week.

Being first to file, with a name that’s actually distinctive, has never mattered more.

The bottom line

AI is a fantastic naming assistant and a terrible naming lawyer. It can hand you a hundred ideas; it can’t tell you which one you’re allowed to own, and it can’t secure it for you. That part still comes down to a real distinctiveness check, a real search, and a real application.

If you’ve got a name you love, whether a chatbot suggested it or you dreamed it up in the shower, the safest next step is to find out whether it’s actually yours to claim.

and we’ll tell you whether your name is worth protecting, before you build a business on it.

Frequently asked questions

Can I trade mark a business name that ChatGPT suggested? Potentially, yes, but only if the name is distinctive and not already taken for similar goods or services. The fact that AI suggested it is irrelevant; what matters is whether the name itself meets Australia’s registrability requirements. Many AI-suggested names are too descriptive to register.

Does using AI to create my name affect who owns it? The trade mark right comes from registration and use, not from who or what generated the word. Using AI to brainstorm doesn’t stop you owning the mark. (Ownership of an AI-generated logo is a separate question, see our article on AI logos and trade mark risk.)

How do I know if my AI-generated name is available? Only a proper clearance search of the Australian Trade Marks Register will tell you. An AI chatbot cannot reliably check this and should never be relied on as confirmation a name is free.

What makes a name easy to trade mark? Invented words, or ordinary words used in a way unrelated to what you sell, are the strongest. Names that describe your product or service are the hardest to protect.
