Can you patent an app?

If you're building a software startup, there is a good chance you've asked yourself this question at some point:

 

"Can I patent my app?"

 

The short answer is yes, potentially.

 

There is a persistent myth that "software cannot be patented", but that is not what the law says. In reality, patents are commonly used by software companies to support fundraising, strengthen competitive positioning, and increase acquisition value.

 

The challenge is understanding which aspects of a software product are potentially patentable, and taking the right steps before it is too late.

 

What Patents Actually Protect

A useful starting point is understanding the different types of IP available to a software company.

 

Copyright protects the code that your developers write.

Trade secrets protect confidential know-how, algorithms, data, processes, and business information that you keep secret.

Trademarks protect your brand name and logos.

Patents protect new and non-obvious functionality and technical innovations.

 

This distinction matters because a competitor does not need to copy your code to compete with you. They can develop their own codebase that delivers substantially the same functionality.

Patents can therefore protect the underlying invention, rather than the specific source code used to implement it.

 

Can You Patent an App?

In most cases, this is actually the wrong question. The more useful question is:

 

"What technical innovation sits behind the app?"

 

An app is simply one way of delivering a software solution. A patent is unlikely to be concerned with the fact that software runs on a smartphone, browser, or cloud platform. Instead, it focuses on the technical solution that the software provides.

 

That solution might relate to:

• how information is processed;
• how data is stored or synchronised;
• how security is improved;
• how performance is enhanced;
• how computer resources are managed;
• how users interact with the system; or
• how different systems communicate with one another.

 

The same principles apply whether the product is a mobile app, SaaS platform, API service, cloud platform, AI product, developer tool, or enterprise software solution.

 

The Key Question: Have You Solved a Technical Problem?

This is often the most important issue for software patents in the UK and Europe.

 

Patent law distinguishes between technical problems and non-technical problems. The latter category includes things such as business methods, commercial rules, administrative processes, and organisational schemes.

 

Many founders hear this distinction and assume their software is not patentable. That is often a mistake.

 

Software development involves solving technical problems every day. Examples might include:

• reducing processing time;
• improving database performance;
• reducing network bandwidth consumption;
• improving cybersecurity;
• increasing reliability of distributed systems;
• improving user interaction with limited screen space;
• optimising memory usage; or
• improving the deployment or operation of machine learning systems.

 

Those are all examples of technical challenges. The fact that the solution is implemented in software does not automatically prevent patent protection.

 

By contrast, a new pricing structure, a referral scheme, a commission model, or an internal management process is less likely to satisfy the technical requirements for patentability if the innovation lies solely in the business concept itself.

 

A useful rule of thumb is this:

If you had to solve a genuine technical challenge to make something work, there may be a patentable invention in that solution.

 

The Mistake That Destroys Most Software Patent Opportunities

There is one issue that prevents more software patents than any other:

 

Launching first and thinking about patents later.

 

To obtain a patent, an invention must generally be new when the application is filed. Once information becomes publicly available, obtaining patent protection may become difficult or impossible.

 

For startup founders, public disclosure can take many forms:

• releasing the product;
• launching a beta version;
• publishing technical details on a website;
• demonstrating functionality publicly;
• presenting at conferences;
• sharing technical information with prospective customers; or
• publishing code repositories.

 

Many founders assume they only need to worry once the product reaches general availability. Unfortunately, patent issues can arise much earlier.

 

A good habit is to ask a patent question whenever a significant technical innovation has been developed:

 

"Should we file before we tell the world about this?"

 

In many cases, a short conversation with a patent attorney before launch can preserve options that might otherwise be lost forever.

 

We've Already Launched. Is It Too Late?

Not necessarily.

 

A public product release does not automatically mean every aspect of the underlying technology has been disclosed.

 

In many software businesses, users only interact with the frontend. Significant elements of the backend architecture, security framework, data processing pipeline, or optimisation techniques may remain hidden from public view. Backend innovations may still be protectable after launch in some circumstances.

 

In addition, most software products are constantly evolving. Even if an early version has been released, subsequent technical improvements may themselves create new patent opportunities.

 

The key message is simple: do not assume the opportunity has been lost. Obtain advice as soon as possible and assess what remains protectable.

 

Is Your Idea Really New?

To be patentable, an invention must be new. Patent law assesses novelty by comparing the invention against everything made publicly available before the filing date. Patent attorneys refer to this body of information as "prior art".

 

One useful indicator is whether your team searched for an existing solution and could not find one that adequately solved the problem. The need to invest significant development effort in creating a new approach is often a sign that something innovative may exist.

 

It is also worth remembering that inventions are frequently combinations of existing technologies. Many patentable inventions do not involve inventing entirely new building blocks. Instead, the invention lies in a new arrangement, interaction, or application of known components.

 

"But Isn't It Obvious?"

This may be the most common misconception among software founders.

 

After living with an invention for months or years, the solution often seems completely obvious to the people who created it. That is not how patent law assesses obviousness.

 

The legal test attempts to remove hindsight and asks whether the invention would have been obvious before the inventor created it. The assessment is performed from the perspective of a hypothetical skilled person. This person is assumed to be technically competent and familiar with the relevant technology, but they are not inventive and do not possess the inventor's insight. They know what was publicly available at the time but are not expected to make inventive leaps.

 

After months spent testing approaches and refining a solution, it is easy to forget how difficult the problem looked at the outset.

 

Many founders therefore dismiss genuinely valuable inventions because they have become too familiar with them. The fact that a solution appears simple once explained does not necessarily mean it was obvious beforehand.

 

AI Products: Can You Patent an AI Application?

This has become one of the most common questions from software startups.

 

Simply applying a machine learning model to a business problem may not be enough. However, patent opportunities can arise where the innovation lies in the technical implementation, deployment, operation, optimisation, or integration of AI systems.

 

For example, founders should pay attention to technical innovations relating to:

• model deployment;
• resource optimisation;
• training efficiency;
• distributed inference;
• security and robustness;
• data processing architectures;
• integration with hardware; and
• improvements to computer operation itself.

 

Many AI startups focus heavily on model performance metrics but fail to document the engineering breakthroughs that enabled those results. Those engineering breakthroughs are often where patentable subject matter may exist.

 

When Should a Startup File a Patent?

There is no universal answer, but earlier is generally better than later.

 

Founders should consider patent protection when they have:

• identified a technical innovation;
• developed enough detail to describe how it works;
• confirmed that the solution appears commercially important; and
• not yet disclosed it publicly.

 

In practice, the ideal time is often shortly before:

• a public launch;
• investor outreach;
• customer demonstrations;
• strategic partnerships; or
• publication of technical details.

 

Waiting until significant commercial traction has been achieved can create unnecessary risk if disclosures have already occurred.

 

Is a Patent Worth It for a Startup?

Patents are not appropriate for every business. However, they can provide significant advantages.

 

Potential benefits include:

• creating barriers to entry;
• strengthening investment discussions;
• increasing acquisition value;
• supporting licensing opportunities;
• protecting core technology from competitors; and
• demonstrating that the company takes IP seriously.

 

What Do Investors Think About Patents?

Most investors do not expect an early-stage software company to have a large patent portfolio. However, investors frequently look for evidence that founders understand and manage intellectual property risk.

 

A well-considered patent strategy can demonstrate that the company has identified its core technology, taken steps to protect it, and avoided losing valuable rights through premature disclosure.

 

This is particularly relevant where a company's value is closely tied to proprietary technology. While patents are rarely the sole reason an investor backs a startup, they can contribute to a broader picture of technological defensibility and long-term value creation.

 

Equally, there are situations where alternative approaches may be more effective. For example, some innovations are difficult to detect from outside the company, making trade secret protection attractive. In other cases, the technology evolves so quickly that patenting may not align with commercial priorities.

 

The right strategy is therefore not simply "patent everything". It is identifying the innovations that are genuinely important to the long-term value of the business.

 

Key Takeaways for Founders

If you remember only five points from this article, make them these:

1. Software and apps can be patented.
2. The focus is usually on solving a technical problem.
3. Many founders underestimate the patentability of their own innovations.
4. Public disclosure before filing can seriously damage patent prospects.
5. The best time to seek advice is usually before launch, not afterwards.

 

Your team is solving technical problems every day. Some of those solutions may become valuable business assets. The challenge is identifying them early enough to protect them.

 

If your team has developed a software solution that solves a technical problem in a new way, it is worth obtaining advice before launching publicly. Identifying patentable inventions early can make a significant difference to the long-term value of the business.
