A freedom to operate (FTO) search helps you determine whether commercialising your invention could infringe someone else’s active patent rights. It focuses on risk, timing, and geography, and is an important step before launching, manufacturing, or selling a new product or service.
What is a freedom to operate search?
A freedom to operate (FTO) search is used to assess whether your invention can be made, used, sold, or commercialised without infringing someone else’s patent rights.
Unlike a patentability or novelty search, which asks “Is my idea new?”, a freedom to operate search asks a different question:
“Could using or selling my invention expose me to infringement risk?”
An FTO search looks for existing, in-force patents that could potentially cover aspects of your product, process, or service. The focus is not on whether you can get a patent, but whether someone else already has enforceable rights that could restrict what you plan to do.
Freedom to operate is always country specific. You may have freedom to operate in Australia, for example, but not in another country where a relevant patent may be in force.
Why freedom to operate matters before you commercialise.
It’s quite common for early-stage inventors to assume that once they have a patent application filed – or once they’ve confirmed their idea is novel – they are “safe” to proceed.
Unfortunately, that isn’t always the case.
A freedom to operate search is particularly important before you:
- Manufacture a product
- Launch or sell a product or service
- Enter licensing or distribution agreements
- Seek investment or commercial partners
At this stage, decisions tend to involve real money, timelines, and commitments, which make unmanaged legal risk far more costly.

Remember the “dark window” in patent publishing.
Even though patent databases are more accessible than ever, there is still an unavoidable limitation known as the publication delay.
There is typically an 18-month gap between when a priority patent application is filed and when it is published.
During this period:
- The application is not visible in public patent databases
- You cannot reliably search for it
- It may later mature into enforceable rights
This means that even a well-conducted FTO search cannot guarantee zero risk. A freedom to operate search helps manage known risks, but it cannot entirely eliminate uncertainty.
This is one reason why FTO is about risk assessment, not absolute certainty.
What are the risks of not doing a freedom to operate search?
Not conducting a freedom to operate search does not automatically mean you will infringe someone’s patent. It does, however, mean you are operating without visibility of potential risks.
Depending on the circumstances, the consequences of infringement can include:
- Being forced to stop selling or using your invention
- Having to redesign or withdraw a product
- Loss of investment or commercial confidence
- Legal costs, damages, or settlement negotiations
For early-stage inventors, these outcomes can be particularly disruptive, especially if they occur after time and money have already been invested.
An FTO search helps you make informed commercial decisions, such as whether to:
- Proceed as planned
- Modify your design
- Delay launch
- Focus on different markets
How is a freedom to operate search done?
Freedom to operate searches focus on patents filed within the past 20 years, as patents older than this will usually have expired.
However, not all patents filed within this timeframe are relevant.
A proper FTO search considers whether patents are:
- Granted or pending
- Still in force (renewal fees must be paid to keep patents active)
- Relevant to your intended use or product features
- Geographically applicable to where you plan to operate
If a patent has lapsed due to non-payment of renewal fees, it generally cannot be reinstated except under limited circumstances. This status information is a critical part of the freedom to operate analysis.
Importantly, freedom to operate searches are not just about finding patents – they also involve interpreting what the patent claims cover. This is often less straightforward than reading the abstract or drawings.
We have in-depth articles that cover how to do a patent search and what we can learn from patent searches.
Freedom to operate vs patent searches: what’s the difference?
This is a common point of confusion.
Patentability or novelty searches.
These searches help determine whether your invention is:
- New
- Inventive
- Potentially patentable
They look backwards to assess what is already known.

Freedom to operate searches.
Freedom to operate searches are forward-looking.
They assess whether existing patent rights could restrict what you want to do commercially.
In short:
- Patentability searches help you protect your invention
- Freedom to operate searches help you avoid infringement risk
A patent or novelty search looks at whether your invention is new and potentially patentable. A freedom to operate search looks at whether existing patents could restrict your ability to commercialise your invention. They answer different questions and are often conducted at different stages.
Both are useful, but they serve very different purposes.
Not sure what your next step should be?
Understanding the difference between patent searches and freedom to operate searches can help you decide what to focus on at each stage.
If you’ve done some initial searching and would like clarity on what the next step might be for your invention, you can get in touch to discuss your options.
Can I do a freedom to operate search myself?
It is possible to conduct a basic, preliminary review of patent databases yourself, particularly to build early awareness of the landscape.
However, freedom to operate searches quickly become complex because they involve:
- Understanding claim scope, not just keywords
- Assessing legal status across jurisdictions
- Interpreting how patents apply to real-world products
For early-stage inventors, a practical approach is often to:
- Start with general education and awareness
- Use early searches to inform strategy
- Seek professional input before making irreversible commercial decisions
This helps balance cost, timing, and risk without overcommitting too early.
When should an FTO search be done?
There is no single “right” time, but an FTO search is most valuable before you commit to actions that are difficult or expensive to undo.
Common trigger points include:
- Preparing for market launch
- Finalising product design
- Entering manufacturing agreements
- Pitching to investors or partners
The earlier you identify potential issues, the more options you usually have.
Frequently asked questions about freedom to operate.
-
What is the purpose of a freedom to operate search?
The purpose of a freedom to operate (FTO) search is to help you determine whether commercialising your invention could infringe existing patent rights. It provides visibility of potential risks so you can make informed decisions before investing heavily in manufacturing, launch, or market entry.
-
Is a freedom to operate search legally required?
No. A freedom to operate search is not legally required. However, many inventors and businesses choose to conduct one as part of responsible risk management before bringing a product or service to market.
-
Does a freedom to operate search guarantee I won’t infringe a patent?
No. An FTO search reduces risk but cannot eliminate it entirely. Patent applications may be unpublished at the time of searching, and patent status can change over time. An FTO search should be viewed to assess and manage risk, not as a guarantee.
-
Do I need a freedom to operate search if I am not seeking a patent?
Possibly. Even if you do not intend to file a patent application, you may still infringe someone else’s patent if you make, use, or sell a product or service that falls within their claims. Freedom to operate is about use, not ownership.
-
When is the best time to do a freedom to operate search?
An FTO search is most useful before you commit to actions that are costly or difficult to reverse, such as manufacturing, launching, entering licensing agreements, or seeking investment. The earlier potential issues are identified, the more options you usually have.
-
Is freedom to operate the same in every country?
No. Freedom to operate is assessed on a country-by-country basis. A patent that is in force in one country may not exist, or may have expired, in another. Your intended markets matter.
Freedom to operate searches: managing risk before you launch.
Freedom to operate searches are not about creating fear or slowing you down – they’re about helping you move forward with clarity.
For early-stage inventors, understanding how your idea fits within the existing patent landscape can help you make better decisions about timing, investment, and next steps.
If you’re still shaping your invention or weighing up next steps, learning how freedom to operate fits into the broader patent process can be a valuable starting point. After you’ve done some initial searching and you want to understand the best next step, you can get in touch to discuss your options for protecting your invention
