Understanding the Two Options
Patents grant you a legally enforceable monopoly over an invention in exchange for publicly disclosing how it works. In Australia, a standard patent under the Patents Act 1990 provides up to 20 years of protection (or 25 years for pharmaceutical substances). An innovation patent previously offered a shorter-term option, but this system was phased out in August 2021. To obtain a standard patent, your invention must be a manner of manufacture, novel, involve an inventive step, and be useful.
Trade secrets, on the other hand, rely on keeping commercially valuable information confidential. There is no registration system for trade secrets in Australia. Instead, protection arises through a combination of contract law (such as non-disclosure agreements and employment contracts), equitable obligations of confidence, and the common law action for breach of confidence. A trade secret can theoretically last forever — but only for as long as the information remains secret.
Key Factors to Consider
1. Can Your Innovation Be Reverse-Engineered?
This is often the single most important question. If a competitor could purchase your product, pull it apart, and figure out how it works, a trade secret offers virtually no protection. Once the information is publicly available — regardless of how it got there — your trade secret is gone, and there is no legal remedy for someone independently discovering or reverse-engineering the same information.
In contrast, a patent protects you even if a competitor independently arrives at the same invention. If your product's inner workings are visible or easily deduced, patent protection is almost always the better choice.
If your innovation involves a process, formula, or method that happens behind closed doors and cannot be discerned from the final product — think manufacturing processes, chemical formulations, or proprietary algorithms — trade secret protection becomes a genuinely viable option.
2. How Long Do You Need Protection?
A standard patent provides a maximum of 20 years of protection, after which your invention enters the public domain. For many industries, particularly those with rapid innovation cycles, 20 years is more than sufficient.
Trade secrets, however, have no expiry date. The Coca-Cola formula is the classic example — it has been protected as a trade secret for well over a century, far longer than any patent could have provided. If your competitive advantage is something that will remain valuable for decades and can be kept confidential, trade secret protection may deliver superior long-term value.
3. What Are the Costs Involved?
Obtaining and maintaining a patent in Australia involves significant costs. There are filing fees payable to IP Australia, professional fees for drafting the specification, costs associated with examination and responding to objections, and annual renewal fees that increase over the life of the patent. For international protection, these costs multiply substantially.
Trade secret protection involves a different kind of investment. You'll need robust confidentiality agreements, secure information management systems, restricted access protocols, and potentially ongoing legal advice to ensure your protections remain enforceable. While the upfront costs may be lower, the ongoing operational burden should not be underestimated.
4. Do You Need to Enforce Your Rights Against Third Parties?
A patent gives you a clear, publicly registered right that you can enforce through the Federal Court of Australia. If a competitor infringes your patent, you have a well-defined cause of action with established remedies including injunctions and damages.
Enforcing trade secret rights is more complex. You need to demonstrate that the information had the necessary quality of confidence, that it was disclosed in circumstances importing an obligation of confidence, and that there was an unauthorised use or disclosure. If a competitor independently develops the same process without any access to your confidential information, you have no claim against them.
5. Is Disclosure Strategically Valuable?
Remember that a granted patent is a published document. While this is often seen as a disadvantage, disclosure can serve strategic purposes:
- Deterring competitors who can see the scope of your protected rights
- Attracting investors and licensees who can assess the value of your IP portfolio
- Establishing priority and a clear public record of your innovation
- Creating licensing revenue streams from third parties who wish to use your technology
If you intend to license your technology or attract investment, a patent provides a tangible, assessable asset. Trade secrets are inherently more difficult for third parties to value.
6. What Is Your Industry and Competitive Landscape?
In some industries, patent protection is almost essential. In pharmaceuticals, biotechnology, and medical devices, the regulatory and investment landscape is built around patent protection. Investors expect it, and the lengthy development timelines justify the cost.
In other sectors — particularly software, food and beverage, and certain manufacturing industries — trade secrets may play a more prominent role. Consider what your competitors are doing and what your industry norms are, but don't follow the crowd blindly.
Can You Use Both?
Absolutely — and many businesses do. A well-constructed IP strategy often involves patenting certain aspects of an innovation while keeping other elements as trade secrets. For example, you might patent the core mechanism of a device while keeping your proprietary manufacturing process confidential. The key is to ensure that your patent application does not inadvertently disclose information you intend to keep secret.
It is worth noting that once you file a patent application, the specification will eventually be published — typically 18 months after the priority date. There is no way to "un-publish" this information if you later change your mind.
Practical Steps for Making Your Decision
- Conduct an IP audit to identify all potentially protectable innovations in your business
- Assess reverse-engineering risk honestly and critically
- Consider your commercialisation strategy — licensing, manufacturing, investment, or sale
- Evaluate your ability to maintain confidentiality across employees, contractors, and business partners
- Seek professional advice before making commitments, particularly before any public disclosure that could jeopardise patent rights
The Bottom Line
There is no one-size-fits-all answer. The right choice depends on the nature of your innovation, your commercial objectives, your industry, and your appetite for the costs and obligations involved in each approach. What matters most is making a deliberate, informed decision rather than defaulting to one option through inertia or assumption.
