This page sets out some of the basic fees associated with patent applications. A full list of fees* is available in Schedule 7 of the Patent Regulations 1991.

Fees are payable at different stages through the patent process and will depend on the type of application you are making.

It is important to remember that these are the fees our office charges for each action. You should expect additional costs if you are using legal representation.

Fees are subject to change. GST does not apply to these statutory fees under division 81 of the Goods and Services Act 1999.

Fees may vary depending on how you apply and your chosen payment method, with online filing channels and payment methods typically being cheaper. Different filing and payment options are offered to ensure our services remain available to everyone, regardless of their access to our online services. The distinction between these options is referred to as 'preferred or other means' and shown in the tables below as 'online services' and 'other means'. More information on preferred or other means can be found here.

Application fees

The application fees you need to pay will depend on the type of patent you apply for.

If you file an application and do not pay the filing fee within two months your application will lapse.

The first fee is if an application is filed through online services. The second is if an application is filed by other means (e.g. post).

Renewal fees

Annual renewal fees must be paid on all standard and innovation patent applications if you want them to remain in force. The cost will vary depending on the type of patent and the number of years that have passed since you filed it. These fees are usually due on or before the anniversary of the filing date of your application.

It is up to you to pay on time. Patent protection will stop if the renewal fee is not paid.

It is important that you keep your contact details up to date by using our online services.

Re-examination request


Innovation patents

Innovation patents do not have to be examined. You can choose to keep your patent as an unexamined innovation patent and never request examination. If competitors request examination of your innovation patent, they have to pay half of the examination fee and you will have to pay the other half. If you do not pay, your patent will cease.

The Australian Government has begun the process of phasing out the innovation patent. Applicants can only apply for innovation patents in limited circumstances for the next 8 years. This includes through divisional applications and the conversion of a standard patent to an innovation patent. This can only occur if the parent application was filed before 26 August 2021. You can learn more about the phase out of the innovation patent here.

Standard patents

Standard patent applications must be examined. You must request examination and pay the examination fee within five years of your filing date. If you haven't requested examination yourself, you may be directed to request examination and pay the examination fee anywhere up to 57 months from your earliest priority date. In this case, you will be given two months to request examination. If you fail to request examination and pay the fee within the required period your application will lapse.

Both innovation and standard patents must be examined before you can enforce your rights.

Acceptance and excess claims

An acceptance fee is only applicable for a standard patent.

Schedule 7 item




Standard patent acceptance



If the specification contains more than 20 claims at acceptance

The sum of:

(a) $250; and

(b) $125 for each claim in excess of 20, up to and including the 30th claim; and

(c) $250 for each claim in excess of 30 (if any)

Voluntary amendments

Amendments to a patent application will incur a fee if they are made at either of these stages:

  • before you request examination
  • after the standard patent application has been accepted.

There is no fee for filing a voluntary amendment on a provisional application. It is also free to amend an innovation or standard patent application after examination has been requested.

Schedule 7 item




Amend standard patent specification before examination or after acceptance


222AProposed amendment increases the claims in the complete specification and exceed 20 claims$250 for each additional claim

International fees

Fees for patents overseas will vary depending on the country you apply in.

Filing separate patent applications in each country may be cost effective if you choose to file in only a few countries.

If you file an application under the Patent Cooperation Treaty (PCT), your application will have automatic effect in the 151 countries in the treaty. This gives you more time to decide whether you want to pursue patent protection and in which countries. Most countries require you to file a patent application within 30 months from your priority date. You have 31 months if you file in Australia. Please check each country's requirements to ensure the correct fees are paid on time.

If you choose to pursue patent protection without professional advice you should take extreme care to understand the fees you will be required to pay and when you are required to pay them.

If you have filed an Australian provisional application with a view to filing a PCT application, you can pay for a patentability search to be carried out by us on your invention before you file your PCT application.

When you file your PCT application you must pay the full international search fee. If we have already conducted a search for your provisional application, you may request a partial refund of the international search fee. The amount of the refund will depend on how much additional searching we need to do on your PCT application.

Fees must be paid for a PCT application within one month of filing the application. Failure to pay these fees will result in the application being withdrawn.

You will also need to pay various national fees in each country where you choose to begin the national phase. Failure to pay a fee can have serious consequences for the protection of your rights.
