Should you patent your invention? A founder's guide to making the right commercial decision

Patents can protect valuable inventions, attract investment and create opportunities for licensing and commercial growth. But obtaining a patent isn't necessarily the right decision for every invention, and knowing when to seek protection can be as important as knowing how.

Developing a new invention can be an exciting moment for an entrepreneur. After months or years of experimenting, researching and refining an idea, the prospect of bringing something genuinely new to market can make patent protection seem like an obvious next step.

But a patent application is not simply a legal formality or a certificate recognising innovation. It is an investment decision that should be informed by the invention's commercial prospects, the markets in which the business intends to operate and the resources available to bring the technology to market.

The important question is not merely whether an invention can be patented, but whether obtaining a patent will materially improve the commercial position of the business.

That distinction matters most for startups and small businesses, where capital is limited, and patent spending must compete with product development, marketing, recruitment, and customer acquisition.

A well-developed patent strategy can preserve valuable commercial opportunities. An indiscriminate approach, however, can consume substantial resources without necessarily producing a corresponding competitive advantage.

Before engaging a patent attorney or committing to an application, founders should understand several common misconceptions about patents and the commercial decisions involved.

Patent protection doesn't have to cost hundreds of thousands of dollars, but the total investment can still be substantial.

The cost of obtaining patent protection depends on the complexity of the invention, the quality of the application, the examination process and the countries in which protection is sought. A relatively straightforward Australian application may cost much less than a sophisticated international portfolio covering several technologies.

As at October 2026, IP Australia's official filing fee for a provisional patent application starts at $100. However, professional preparation and filing typically cost about $4,000 to $7,000, with additional expenses if the business proceeds to a complete application.

For a startup, the more important financial consideration is the cost of the entire patent strategy rather than the initial filing.

Patent drafting, examination, responses to objections, overseas applications, and renewal fees can create ongoing costs over several years. Businesses should therefore obtain a realistic estimate of likely future costs before making the initial commitment.

A patent may discourage copying, but it does not make infringement impossible.

Some inventors question whether patents are worthwhile because larger competitors may have the resources to imitate their technology and defend infringement proceedings. That concern is understandable, particularly where the startup lacks the financial capacity to fund expensive litigation.

However, the possibility of infringement does not make patent protection commercially irrelevant. Meaningful patent rights can influence competitor behaviour, strengthen licensing negotiations,s and provide a legal basis to challenge unauthorised exploitation.

The practical value of those rights depends on their scope, validity and enforceability, as well as the patent owner's resources.

A patent covering commercially important product features may provide substantial leverage. A narrow patent that competitors can easily design around may offer comparatively little protection, regardless of the expense incurred obtaining it.

No patent is worldwide.

Patent rights are territorial, so companies must pursue protection in the countries or regions relevant to their commercial strategy. An Australian patent does not automatically prevent competitors from manufacturing or selling the invention in the United States, Europe or Asia.

International filing mechanisms, including the Patent Cooperation Treaty, can simplify and coordinate protection across multiple jurisdictions. However, they do not create a single enforceable patent covering the entire world.

For founders, the challenge is deciding where protection is commercially justified.

A company should consider its principal customer markets, relevant manufacturing locations, potential competitors and the practical costs of enforcing rights. Filing in every possible jurisdiction may be neither affordable nor commercially sensible.

The aim should be to protect the markets that matter to the business, rather than accumulate registrations without a clear commercial purpose.

Patent attorneys are professional advisers, not potential competitors.

Inventors sometimes hesitate to disclose technical details because they fear that an adviser might appropriate their invention. Registered patent attorneys in Australia and New Zealand are subject to professional obligations concerning confidentiality, conflicts of interest and ethical conduct.

These obligations allow inventors to discuss sensitive technical information to obtain appropriate professional advice. Patent attorneys also combine legal expertise with technical qualifications, enabling them to assess inventions that may involve complex scientific or engineering principles.

The quality of the relationship nevertheless matters.

A patent attorney cannot prepare an effective application without understanding how the invention works, what distinguishes it from existing technology and which features may deserve protection. Withholding significant information can undermine the quality of the advice and the resulting application.

A patent does not enforce itself.

Once a patent is granted, the owner ordinarily remains responsible for monitoring the market and identifying potentially infringing activity. There is no general government enforcement service that automatically investigates every suspected infringement on behalf of patent owners.

Businesses should therefore consider how they will monitor competing products and respond if infringement is suspected.

That may involve periodic market searches, monitoring competitors' patent activity, obtaining professional infringement advice or engaging in commercial negotiations. Litigation may ultimately be necessary in some circumstances, but it should be assessed against the likely costs, remedies and commercial outcomes.

The ability to obtain a patent and the financial capacity to enforce it are separate considerations.

Most importantly, a patent does not automatically make an invention commercially successful.

An inventor may obtain broad legal protection for a technically novel product without showing that customers will buy it.

A patent does not create market demand, establish viable manufacturing economics or provide the sales and distribution capabilities necessary to build a business. Those matters require independent commercial assessment.

This is illustrated by the Mango Stick, an invention discussed in IP Australia's 2017 guide to engaging patent attorneys.

The product was designed to make mangoes easier to peel, slice and eat by holding the fruit securely through its seed. Its inventor, Andrey Zoska, and his family explored patent protection and manufacturing options but ran into production-cost issues and limited customer interest.

Market testing suggested that many potential customers did not see the problem as important enough to justify buying a dedicated product. The family eventually decided against further investment in the patenting process, potentially avoiding substantial additional expenditure.

The lesson is not that the invention lacked originality or ingenuity.

Technical ingenuity and commercial demand are different things, and the first does not establish the second.

A business should understand whether customers value the solution before committing substantial resources to protecting it.

Five questions should inform the decision to pursue patent protection.

The first is whether the invention is genuinely new and meets the legal requirements for patentability. In Australia, a standard patent generally requires an invention that is novel, involves an inventive step, utility, and patentable subject matter.

Not every useful improvement, software application or commercial concept qualifies. A product may be commercially attractive while lacking the technical or legal characteristics necessary for patent protection.

The second question is whether similar technology already exists.

Founders should search relevant patent databases, technical publications, academic research and competing products to understand the existing technological landscape. An invention that appears original within a particular industry may already have been described elsewhere.

The third question concerns disclosure.

Publicly demonstrating, selling or publishing information about an invention before filing can affect its patentability. Australia provides a limited 12-month grace period for certain disclosures, but not every jurisdiction offers equivalent protections.

Consequently, consider confidentiality and filing decisions before approaching the market.

The fourth question is whether the invention has a credible commercial application. This requires identifying the customer problem, evaluating potential demand and understanding how the product or technology might generate revenue.

The fifth is whether the inventor possesses the resources and capabilities necessary to exploit the invention.

A researcher may have the expertise to develop a technology but lack the capital, manufacturing experience or distribution network required to commercialise it. In those circumstances, licensing or partnering with an established business may be more appropriate than building an independent operation.

The answers should inform the patent strategy, not simply determine whether an application is possible.

A startup may have a patentable invention but decide against filing because the anticipated market is too small. Another may pursue protection because the technology is difficult to reproduce independently and commercially important to a prospective licensing partner.

Neither decision is inherently wrong. The relevant question is whether the expenditure creates a reasonable prospect of commercial benefit.

A patent should fit the company's business model.

A startup planning to manufacture and sell its own products may use patents to protect important technical features from imitation. A company intending to license its technology may instead focus on securing rights that are broad and clearly defined enough to support negotiations with commercial partners.

For a university spinout, patent rights may be central to the business's ability to attract investment. However, investors will also assess whether the company owns or controls the rights needed to commercialise the underlying research.

A university-owned patent licensed to a startup may provide a strong foundation for commercialisation, but the licence terms can materially affect the company's position.

Restrictions concerning exclusivity, permitted fields of use, royalties, sublicensing, termination and transfer may become particularly important during fundraising or acquisition negotiations.

The appropriate legal structure should therefore be considered alongside the patent application itself.

Founders should also distinguish patentability from freedom to operate.

A company can obtain a patent over an improvement to existing technology while still requiring permission to use an earlier invention protected by another party's patent.

This is because a patent grants the right to exclude others from exploiting the claimed invention, not unrestricted permission to commercialise the technology.

A patentability search investigates whether an invention satisfies the requirements for patent protection. A freedom-to-operate assessment examines whether the company's intended commercial activities may infringe relevant third-party rights.

These inquiries serve different purposes and should not be confused.

For technology businesses, both may matter when deciding whether to invest in product development, manufacturing, and market entry.

Patent searching is a useful starting point, but it requires careful interpretation.

Inventors can undertake preliminary searches using publicly available patent databases and general research tools.

Relevant sources include IP Australia's patent search services, Google Patents, the European Patent Office's Espacenet database and international patent information available through WIPO.

Searches should not be restricted to the precise terminology used by the inventor. Similar technologies may be described using different technical language, particularly in patent specifications.

For example, a patent concerning a beverage container may use terminology involving fluid receptacles, dispensing mechanisms or particular structural features rather than the everyday name of the product.

Identifying relevant patents is only the first stage.

You must also examine their claims, legal status, filing dates, and territorial coverage to understand their potential significance. An expired patent may no longer create an enforceable exclusionary right but can still contain prior art relevant to whether a new invention is patentable.

No search can guarantee it has identified every relevant document, especially when unpublished applications or hard-to-find disclosures exist.

A well-prepared inventor can make professional advice more effective.

Before meeting a patent attorney, founders should prepare a clear explanation of the invention and the problem it addresses.

They should identify the technical features they believe distinguish it from existing products, supported by sketches, technical drawings, prototypes or experimental results where available. They should also disclose any relevant publications, demonstrations, sales, investor discussions or other communications that may have revealed the invention.

Information about competing technologies and preliminary search results can help the attorney assess the likely scope of protection.

Just as importantly, founders should explain the commercial strategy.

An attorney assessing an invention intended for licensing across several international markets may recommend a different approach from one advising a small business planning to manufacture a specialised product exclusively for Australian customers.

The patent strategy should reflect how the business expects to make money.

The first meeting should establish both legal options and commercial expectations.

A productive initial consultation should examine the nature of the invention, potential patentability, ownership, prior disclosures and the relevant technological landscape.

The attorney should also discuss possible filing pathways, timing, international protection, and likely costs. Founders should seek clarity on what the initial engagement includes and what additional expenses may arise during examination, prosecution,n and overseas filing.

The attorney provides specialised technical and legal advice.

The founder is responsible for deciding whether the proposed investment makes commercial sense.

These responsibilities are complementary, but not interchangeable.

The right patent attorney should understand the technology and the commercial objective.

IP Australia's original guide illustrates this point through the experience of medical researcher Dr Nick Gorgani, who sought patent advice on a proposed treatment for Type 2 diabetes.

The account emphasises the importance of working with an attorney who understands both the invention's scientific characteristics and the legal requirements for protection. It also shows how theinventor's technical information can shape the quality of the patent specification.

For founders, the broader lesson concerns the nature of the professional relationship.

An effective patent attorney should challenge assumptions about novelty, explain uncertainty, and identify the consequences of different filing strategies. An effective client should provide complete information, communicate commercial priorities and remain involved in important decisions.

The goal is not simply to obtain a patent application that can be filed, but to pursue rights that are useful to the business.

Patent protection should develop as commercial opportunities develop.

A different example from IP Australia's guide concerns Stormseal, a product Australian carpenter Matthew Lennox developed to provide temporary weather protection for damaged roofs and buildings.

According to the guide's historical account, Lennox recognised the importance of protecting the technology early and pursued patent protection concerning different aspects of the product. As the business expanded its international ambitions, it also pursued protection in additional jurisdictions.

The example illustrates the relationship between intellectual property and commercial growth.

The business did not necessarily need to pursue every possible overseas registration at the outset. Its patent strategy developed alongside decisions about manufacturing, market entry and commercial expansion.

For startups with limited capital, this approach can be particularly important.

Initial expenditure should preserve valuable options without requiring the company to commit prematurely to every possible market. The company can then consider further protection as commercial evidence and available financing improve, subject to applicable filing deadlines.

Patent protection should be viewed as an investment, not a sunk cost.

Once a company has filed an application, it may feel compelled to continue because it has already invested significant time and money.

That reasoning can lead to further expenditure even when the commercial assumptions supporting the original decision have deteriorated.

A better approach is to reassess the value of proceeding at each significant stage.

Has customer demand developed as expected? Is the technology still commercially relevant, and do the claims likely to be granted provide meaningful protection against competitors?

Are the anticipated markets still attractive, and does the business have sufficient resources to commercialise the invention?

The answers may justify continuing, modifying or abandoning the strategy.

A decision not to proceed with patent protection can be commercially sound where the expected benefits no longer justify the cost.

The real purpose of patent protection is to strengthen the business.

Patents can strengthen a company's competitive position by discouraging imitation, supporting investment discussions, enabling licensing, and preserving opportunities for commercial expansion.

However, those benefits depend on how the legal rights align with the underlying business model.

A patent that protects commercially unimportant technology may create little value. An invention that solves an important customer problem but lacks an effective commercialisation strategy may never generate sufficient returns to justify the patent expenditure.

Conversely, carefully selected intellectual property rights can help a small company negotiate with much larger organisations, protect valuable product features and capture more of the economic returns from its innovation.

For founders, the decision to engage a patent attorney should therefore begin with an understanding of the commercial opportunity and the risks to that opportunity.

The relevant questions are not simply whether the invention is new or whether an application can be filed.

They are what makes the invention commercially valuable, how competitors might reproduce that value, and whether patent protection will materially improve the company's ability to capture it.

A patent is a legal right, but the decision to obtain one is ultimately a commercial judgment.

The businesses that approach intellectual property most effectively are not necessarily those that file the most patents. They are those that understand which inventions deserve protection, what that protection is intended to achieve and when further investment is justified.

The objective is not to own a patent for its own sake, but to build a business whose competitive advantages are worth protecting.
