Understanding intellectual property begins with knowing what types of protection exist. Under Australian law, there are four principal forms of IP protection, each covering different types of creative and commercial output. This guide explains what each type protects, how protection is obtained, and when businesses should consider applying.

1. Trade Marks

A trade mark is a sign used to distinguish the goods or services of one trader from those of another. Under the Trade Marks Act 1995, a trade mark can be a word, phrase, letter, number, sound, smell, shape, logo, picture, aspect of packaging, or a combination of these.

Trade mark registration is administered by IP Australia. Registration gives the owner exclusive rights to use the mark in connection with the goods and services for which it is registered, and the right to take action against unauthorised use. Registration lasts for 10 years and is renewable indefinitely.

Key facts:

Unlike copyright, trade mark protection is not automatic — it must be applied for and registered. While common law trade mark rights exist through use, registered trade marks provide significantly stronger legal protection and are generally easier to enforce.

2. Patents

A patent protects new inventions — including devices, substances, methods, or processes — that are novel, involve an inventive step, and are useful. The Patents Act 1990 provides for two types of patent:

Patent applications require detailed technical descriptions and claims that define the scope of protection sought. The examination process is rigorous and typically requires the assistance of a registered patent attorney. We cover this topic in how to register a trademark in australia:.

3. Designs

Design registration protects the visual appearance of a product — its shape, configuration, pattern, or ornamentation. Protection under the Designs Act 2003 covers the way a product looks, not how it works (which is the domain of patents).

Key facts:

Design registration is particularly relevant for consumer products, packaging, furniture, fashion items, and digital interfaces where visual identity is a commercial asset.

Copyright protects the expression of ideas in material form. Unlike trade marks, patents, and designs, copyright protection in Australia is automatic — it arises the moment an original work is created and does not require registration. Australia does not have a copyright registration system. See also our 20 best ip lawyers in australia.

Copyright applies to:

Under the Copyright Act 1968, copyright generally lasts for the life of the creator plus 70 years. For works with corporate authorship, the duration is typically 70 years from the date of first publication.

How the Four Types Interact

Many businesses need multiple forms of IP protection. A consumer electronics company, for example, might hold:

Understanding which protections apply — and in what priority — is one of the most important early decisions for any business developing commercially valuable intellectual property.

When to Seek Professional Advice

While basic IP concepts are accessible, the application and enforcement of IP rights involves complex legal and technical considerations. Trade mark and patent applications in particular benefit from professional guidance. IP professionals in Australia include registered trade marks attorneys (who specialise in trade mark work), registered patent attorneys (who handle patents and designs), and IP lawyers (who may advise across all four areas and handle litigation).

For most businesses, the starting point is identifying which types of IP they have, which are most commercially important, and which require formal protection. An IP audit — whether conducted internally or with professional assistance — is a practical first step.
