How to search existing patents

Before you apply for a patent, you need to check if your invention already exists.

You should search on the:

  • Internet (including Google Patents and social media).
  • IP search databases (Australian and international).

As part of the examination process, we'll also perform extensive searches. If we find a product or invention that's too similar to yours, we'll let you know.

Check the IP search databases

You can use online IP search databases to look up the details of IP rights filed by others.

The Australian Patent Search database contains details for patent applications and grants.

There are many ways you can search, including by:

  • invention title
  • applicant
  • inventor
  • World Intellectual Property Organization (WIPO) or Patent Cooperation Treaty (PCT) number
  • filing date
  • priority date.
