Locarno classification and product names

The Locarno Classification system is used to group designs into different classes and sub-classes. This makes it easier to find similar types of products during your design search.

How it works

The Locarno Classification system consists of 32 classes and many are divided into sub-classes. In Australia, we use additional sub-sub-classes to distinguish products even more precisely.

You don't need to tell us what your product's classification code is. We'll classify your design according to what the purpose of your product is.

Classification codes and sub-codes are shown as two sets of two-digit numbers separated by a hyphen, such as 05-06. Sub-sub-classes are shown with a letter, like 05-06A.

For example

If your product is a swimsuit, it would be assigned the classification code 02-02A.

  • 02 is the class assigned to articles of clothing and haberdashery
  • 02 is the sub-class assigned to garments
  • A is the sub-sub-class assigned to swimsuits, swimming and bathing costumes

If your product is a snare drum, it would be assigned the classification code 17-04.

  • 17 is the class assigned to musical instruments
  • 04 is the sub-class assigned to percussion instruments
  • There's no relevant sub-sub-class for this product.

It's important to clearly describe and name your product

You'll need to provide a product name as part of your application. This is the generic name of the product. It's important to provide a clear and precise, yet short, product name so that we can classify your product into the right Locarno class.

The name should:

  • Match the representations shown in the application
  • Only describe the nature of the product.

You don't need to include a description of how it works, what it’s made from or the brand name as part of the product name.

If your product has more than one genuine purpose, it may be allocated to more than one classification.

What happens if the product name isn't clear

If your product name is unclear, it may:

  • Delay processing of your application
  • Make it difficult to protect if the design scope isn't clear
  • Create issues for the public in understanding the protection you seek
  • Make it harder for others to find your design in our database.

For example

You provide the product name ‘container’. This isn't specific enough as there are multiple kinds of containers in more than one Locarno class, such as:

  • cutlery container, Classification code: 07-07
  • egg container, Classification code: 09-03
  • medical fluid-collection container, Classification code: 24-02.

Search the list of classification codes

To help with your existing design search, you can look for items with the same classification code.

Search tip: click the classification lookup button in the advanced search page, and click on the classes to the left.

Australian Design Search 

At times, there may be differences between the Australian Design Search and Locarno Classification database. In case of inconsistencies, the Australian Design Search classification codes will take precedence.
