One of the most common questions from inventors and businesses considering patent protection is: how much does it cost to file a patent in Australia? The total cost to file a patent in Australia depends on the application type, the complexity of the invention, the number of claims, and whether you use professional support. This guide breaks down IP Australia government fees and explains what to budget for in 2026.
IP Australia Patent Fees in 2026
IP Australia charges government fees at each stage of the patent process. These fees apply regardless of whether you self-represent or use an IP professional. The fee schedule below is based on current IP Australia rates (subject to annual adjustment).
Provisional Patent Application Fees
A provisional application is the lowest-cost way to establish a priority date in Australia. Government fees are:
- Standard entity filing fee: approximately AUD $370
- Small entity filing fee: approximately AUD $110 (individuals, small businesses)
A provisional application does not attract examination fees. It has a 12-month lifespan, after which you must file a complete or PCT application or lose the priority date.
Complete (Standard) Patent Application Fees
Filing a complete patent application attracts several government fees across different stages:
Filing Fee
- Standard entity: approximately AUD $370 (filing) + additional claims fees for more than 20 claims
- Small entity: approximately AUD $110 reduced rate applies
Request for Examination Fee
- Standard entity: approximately AUD $490
- Small entity: reduced rate applies
Acceptance Fee
- Standard entity: approximately AUD $250
Annual Renewal Fees
Once granted, a standard patent requires annual renewal fees to remain in force for up to 20 years. Renewal fees increase over time, starting from approximately AUD $300 per year in the early years and increasing to over AUD $800–$1,000 per year in the later years.
PCT International Patent Application Fees
A PCT (Patent Cooperation Treaty) application is significantly more expensive than a domestic application due to international filing fees. Key costs include:
- International filing fee: approximately USD $1,452 (based on current WIPO fee schedule) for applications of up to 30 pages, with additional page fees for longer specifications
- Search fee: approximately AUD $2,200 (if IP Australia conducts the search as International Searching Authority)
- National/regional phase entry fees: payable separately in each country when entering the national phase, varying by jurisdiction
Professional Fees for Patent Services
In addition to IP Australia government fees, most applicants engage IP professionals to assist with specification drafting, prosecution, and portfolio management. Professional fees vary widely depending on the complexity of the invention and the scope of services required:
- Patent specification drafting (provisional): typically AUD $2,000 to $8,000+ depending on technical complexity
- Complete specification drafting: typically AUD $5,000 to $20,000+ for complex inventions
- Examination response/prosecution: typically AUD $500 to $3,000+ per response depending on the issues raised
- PCT filing support: professional fees in addition to government fees

Total Cost Estimates: Domestic Patent in Australia
For a straightforward Australian patent application, total costs from provisional filing through to grant typically fall in the following ranges:
- Self-represented (small entity): AUD $1,000 to $3,000 in government fees over the life of the application (excluding professional fees)
- With professional support (standard complexity): AUD $10,000 to $25,000 total from provisional through to grant
- Complex inventions or contested examinations: AUD $25,000 to $50,000 or more
These are indicative ranges only. Actual costs vary significantly based on the invention, the number of claims, examination complexity, and whether amendments are required. ipReNewAl provides case-specific cost guidance as part of its patent application drafting support.
Are There Ways to Reduce Patent Filing Costs in Australia?
Yes. Several strategies can help manage the cost of filing a patent in Australia:
- Small entity concessions: IP Australia offers reduced fees for individuals and businesses with fewer than a specified number of employees. Always check current eligibility criteria before filing.
- File a provisional first: A provisional application costs significantly less than a complete application and buys time to develop the invention and assess commercial viability before the larger investment.
- Request examination when ready: You have up to 5 years to request examination (2 years in some cases). Timing this appropriately can help manage cash flow.
- Keep the specification focused: Excessive claims and page counts increase filing fees. A well-drafted, focused specification can reduce costs.
Patent Costs vs Value: Is It Worth Filing?
For inventors and businesses with commercially valuable innovations, patent protection can deliver significant long-term value through exclusive rights, licensing opportunities, and competitive advantage. The key is assessing whether the expected commercial return justifies the investment. ipReNewAl assists clients with both the patent and trademark landscape in Australia to help make these decisions.
Frequently Asked Questions: Cost to File a Patent in Australia
What is the cheapest way to file a patent in Australia?
The lowest-cost approach is to file a provisional patent application as a small entity (AUD $110 government fee). However, a provisional alone does not result in a granted patent — you must file a complete application within 12 months. Self-representation reduces professional fees but increases the risk of a poorly drafted specification that limits commercial value.
Does IP Australia charge ongoing fees after a patent is granted?
Yes. Annual renewal fees are payable each year to keep a granted patent in force. Missing a renewal fee deadline can result in the patent lapsing. ipReNewAl provides IP renewal management services to help patent holders track and pay renewal fees on time.
Are patent fees tax-deductible in Australia?
Patent application and maintenance fees may be deductible as business expenses in certain circumstances under Australian tax law. You should seek advice from a qualified tax professional regarding your specific situation.
