Cost to File a Patent in Australia 2026 | Full Fee Guide

Overview: What Does It Cost to File a Patent in Australia?

The total cost to file a patent in Australia in 2026 depends on the type of application, whether you use a patent attorney, the complexity of your invention, and how many countries you want protection in. At the simplest end, a provisional patent application can be filed for as little as $110 in government fees. At the more complex end, a full standard patent through to grant with professional representation can cost $10,000 to $30,000 or more over the life of the patent.

This guide breaks down all the costs involved so you can plan your patent strategy and budget accordingly.

IP Australia Government Filing Fees (2026)

All patent applications in Australia must be filed with IP Australia, the government body responsible for granting patents. The following are the key government fees as of 2026. Note that IP Australia periodically adjusts fees, so always verify current figures on the official IP Australia website.

Provisional Patent Application

A provisional patent application establishes your priority date and gives you 12 months to refine your invention before filing a complete application. Government fees are minimal:

Filing fee (electronic): approximately $110
No examination required: provisional applications are not examined by IP Australia

Professional fees (patent attorney) for drafting a provisional specification typically range from $1,500 to $4,000, depending on complexity. Some inventors draft their own provisional to minimise costs, though this carries risk if the specification does not adequately disclose the invention.

Complete Standard Patent Application

A complete (standard) patent application is the full filing that can lead to a granted patent, valid for up to 20 years (25 years for pharmaceuticals). Government fees include:

Filing fee (electronic): approximately $370
Additional claims fee: approximately $110 per claim over 20 claims
Request for examination fee: approximately $490
Acceptance fee (on grant): approximately $200
Annual renewal fees: Begin after the 4th year and increase progressively (see below)

Professional fees for drafting a complete patent specification with formal claims typically range from $5,000 to $15,000 or more, depending on the technology area, the complexity of the invention, and the number of claims.

Annual Renewal Fees for Australian Patents

Once filed, a standard patent must be renewed each year to keep it in force. Renewal fees begin after the 4th year from the priority date and increase over time. The approximate schedule is:

Year 5: approximately $300
Year 6: approximately $325
Year 7: approximately $375
Year 8: approximately $425
Year 9: approximately $475
Year 10: approximately $530
Years 11-15: approximately $600 to $900 per year
Years 16-20: approximately $1,000 to $1,300 per year

Over the full 20-year patent term, total renewal fees paid to IP Australia will be in the range of $10,000 to $15,000 in government fees alone. ipReNewAl manages patent renewal deadlines and payments to ensure your patent never lapses due to a missed renewal.

PCT International Patent Application Costs

If you want to protect your invention in multiple countries, the Patent Cooperation Treaty (PCT) is the most cost-effective pathway. Rather than filing separately in each country, a single PCT application gives you access to 150+ countries and delays the cost of national phase entry until 30-31 months from your priority date.

PCT costs include:

International filing fee (WIPO): approximately USD $1,330 to $1,660 depending on number of pages
Transmittal fee (IP Australia as receiving office): approximately $200
Search fee (IP Australia as ISA): approximately $2,200 (varies by technology)
Total PCT filing cost (AU applicants via IP Australia): approximately $3,500 to $4,500 in fees

Professional fees for filing a PCT application add further cost, typically $2,000 to $5,000 depending on the attorney and complexity. After the PCT phase, national phase entry fees in each target country must be paid — these vary widely by jurisdiction.

Total Cost Scenarios: Budget Guide

To give you a practical sense of what to expect, here are three common scenarios:

Scenario 1: Provisional Only (Testing the Waters)

Filing a provisional patent application to secure a priority date while you assess commercial viability:

Government fee: ~$110
Patent attorney to draft specification: ~$2,000 to $4,000
Total Year 1: approximately $2,100 to $4,100

Note: After 12 months, you must file a complete application or PCT, or lose your priority date.

Scenario 2: Australian Patent Only (Provisional + Complete)

Protecting your invention in Australia through to grant:

Provisional filing: ~$2,000 to $4,000 (including attorney)
Complete application + examination: ~$6,000 to $12,000 (including attorney drafting, government fees, examination response)
Annual renewals (Years 5-20): ~$10,000 to $15,000 in government fees
Total estimated cost over 20 years: approximately $18,000 to $31,000+

Scenario 3: International Filing via PCT (AU + Key Export Markets)

Protecting in Australia plus USA, Europe, UK, and one or two Asian markets:

Provisional + complete AU application: ~$8,000 to $16,000
PCT filing: ~$5,000 to $9,000
National phase entry (e.g. USA, EPO, UK, JP): ~$8,000 to $20,000+ depending on jurisdictions
Prosecution and renewals in each country: ongoing, highly variable
Total estimated cost through grant in 4-5 countries: approximately $50,000 to $100,000+ over the patent term

Factors That Affect Total Patent Costs

The estimates above are indicative. The actual cost of your patent will vary depending on:

Technology complexity: Biotechnology, pharmaceutical, and software patents often require more complex specifications and longer examination processes, increasing attorney fees.
Number of claims: More claims mean higher government fees at the complete application stage. Each claim over 20 incurs additional fees.
Examination objections: If IP Australia raises adverse reports (objections) during examination, responding to each adds to attorney fees. Some applications require multiple rounds of examination.
Speed of prosecution: Requesting expedited examination (available for certain circumstances) can increase fees.
International filings: Each country has its own government fees and typically requires local patent agents, multiplying costs significantly.
Translation costs: Filing in Japan, China, Korea, Germany, and other non-English countries requires official translations, adding thousands of dollars per jurisdiction.
Maintenance/renewals: Keeping patents alive in multiple countries requires annual renewal payments in each jurisdiction. Missing a deadline can cause the patent to lapse.

Ways to Reduce Patent Costs in Australia

Smart patent strategy can help manage costs without sacrificing protection:

File a provisional first: A provisional is cheap and buys you 12 months to validate your invention commercially before committing to the higher cost of a complete application.
Use PCT strategically: Rather than filing in 10 countries immediately, file a PCT application and delay national phase decisions until you know which markets are most important.
Keep claims focused: Work with your attorney to draft a tight set of high-value claims rather than a large number of broad ones. Quality over quantity is often more cost-effective.
Use IP Australia fee reductions (if eligible): Some fee concessions may be available in specific circumstances. Check the IP Australia website for current concession categories.
Use a professional renewal service: Missing a renewal deadline means your patent lapses and protection is lost permanently. A renewal management service like ipReNewAl protects your investment by tracking all deadlines across jurisdictions.

Frequently Asked Questions

What is the cheapest way to file a patent in Australia?

The cheapest option is to file a provisional patent application yourself (self-represented) with IP Australia, which costs approximately $110 in government fees. However, a poorly drafted provisional can leave gaps in your protection that may prevent a complete patent from being granted later. For most inventors, engaging a patent attorney to draft the provisional — typically $1,500 to $4,000 — is worth the investment to ensure the specification is sound.

How much does a patent attorney charge in Australia?

Australian patent attorney fees vary by firm, experience level, and complexity. For a provisional application, expect to pay $1,500 to $4,000 in professional fees. For a complete standard patent application through to grant (including drafting, examination responses, and grant), total attorney fees can range from $5,000 to $20,000 or more. PCT applications add further cost. It is worth requesting a fee estimate upfront from your attorney before engaging their services.

How long does it take to get a patent granted in Australia?

From filing a provisional application, the typical timeline to grant of a standard patent in Australia is 3-5 years. The examination process alone typically takes 12-24 months after the request for examination is lodged. You can request expedited examination in certain circumstances to potentially reduce this timeline. During examination, IP Australia may raise objections that require responses, which adds time.

Do I need to pay renewal fees before the patent is granted?

No. Annual renewal fees for Australian standard patents begin after the 4th year from the priority date (the date of your provisional application, if filed). If your patent is granted before this time, renewal fees begin immediately. If not yet granted by Year 4, you still need to pay the renewal fee to keep the application alive while it proceeds through examination. ipReNewAl can manage these deadlines for you.

Are there fee concessions for small businesses or individuals?

IP Australia does not currently offer a formal small entity fee reduction equivalent to the USPTO micro/small entity discount. However, filing electronically (rather than on paper) attracts lower fees, and there may be specific concession categories. Check the current IP Australia fee schedule at ipaustralia.gov.au for the latest information on any available reductions.
