Words which are descriptive, commonly used or deceptively similar to existing trademarks are harder to register and may be rejected by the examiner.
Some things that are more difficult to register than others:
- Marks that are identical to, or very similar to, earlier filed trademarks for similar goods or services.
- Descriptive terms ("apple" for computers might be acceptable, but "apple" for fruit wouldn't be).
- Common surnames and geographical place names by themselves.
- Very short combination of letters and numbers (such as "VP" or "F9").
- Commonly used words or phrases, such as "Best Quality" or "On Sale".
In those cases the examiner will most likely request evidence that when people think of that Mark, they think of your business and not anyone else. Combining the mark with other unique elements may help registration. For example, "Smith Pluming" would be difficult to register alone, but may be easier when combined with a unique logo or slogan.
If a Mark is deceptively similar to an existing registration, the examiner will most likely request you to amend your description of goods and services so that your registration does not overlap with other existing registrations. For example, "apple" could be registered by one company for computers and a different company for t-shirts, but different companies couldn't both register "apple" for computers.
Marks that are scandalous, misleading or protected by Australian laws (such as ‘ANZAC’, "champagne" and Olympic marks) may not be registered.
Even if your application is accepted, others may oppose its registration or take legal action against you for infringement of unregistered common law trademarks. It's therefore advisable that you search public information (such as Google) to ensure that nobody else is using the mark before you apply.
