What Can Be Patented? (2026 Updated)

If you've built something new - a product, a process, or even a clever way of making something faster and cheaper - it's natural to wonder whether you can patent it.

Patents can be one of the most powerful forms of protection in the UK, but they're also one of the most misunderstood. The rules aren't just about "is it a good idea?" - they're about whether your idea fits within what patent law actually protects.

Below, we'll walk you through what can be patented in the UK (as at 2026), what can't, and the practical steps you can take to protect your invention from day one.

What Is A Patent (And What Does It Actually Protect)?

A patent is a legal right that can give you a time-limited monopoly (usually up to 20 years) over an invention in exchange for publicly disclosing how it works.

In simple terms, a patent can let you stop other people from:

• making your invention,
• using your invention,
• selling your invention, or
• importing your invention into the UK,

?without your permission.

In the UK, patents are governed primarily by the Patents Act 1977 and administered by the UK Intellectual Property Office (UKIPO). The UK system also aligns closely with the European patent framework (via the European Patent Convention), which matters if you want broader coverage beyond the UK.

Patents vs Trade Marks vs Copyright (Quick Comparison)

It helps to be clear about what a patent is not, because many businesses accidentally chase the wrong IP protection.

• Patents protect how something works (technical inventions).
• Trade marks protect your brand identifiers (name, logo, sometimes slogans). A Trade Mark is often the right move if your "idea" is really a brand.
• Copyright protects original creative expression (written content, code as a literary work, designs/artwork in many cases). It can be useful, but it generally doesn't stop someone independently creating the same functional idea.

Many startups and SMEs end up needing a mix of protections - and sorting that out early can save a lot of time and cost later. An IP Health Check can be a practical way to map what you own and what protections fit best.

What Can Be Patented In The UK?

In the UK, an invention generally needs to be:

• new (not already publicly disclosed anywhere in the world),
• inventive (not an obvious modification to what already exists), and
• capable of industrial application (it can be made or used in some kind of industry - broadly interpreted).

So what kinds of things does that cover in real business terms?

1) Physical Products And Devices

This is the classic patent scenario: a tangible product with a new technical feature.

Examples (in plain English) might include:

• a new mechanical fastening system that's stronger or easier to assemble,
• a sensor device that measures something in a new way,
• a medical device component that solves a specific technical problem,
• a packaging design that has a functional technical effect (not just appearance).

One practical tip: patents are about the technical idea, not just "a product you're selling". If your product is mainly about the look/shape, a registered design might be more appropriate.

2) Processes And Methods (Including Manufacturing Methods)

You can often patent a method or process if it produces a technical result.

For example:

• a new way of manufacturing a material that reduces waste,
• a chemical process that improves yield,
• a method of treating a surface to increase durability,
• a process for calibrating equipment that improves accuracy.

This is particularly relevant for businesses where the value is in "how you do it" rather than just the end product. If you're working with suppliers, manufacturers, or contractors while developing the process, locking down confidentiality is crucial - a Non-Disclosure Agreement can help you disclose information without giving away your novelty.

3) Improvements To Existing Technology

You don't need to invent something entirely from scratch to get a patent.

Many patents are granted for improvements, provided those improvements are:

• genuinely new, and
• not obvious to a skilled person in that field.

For example, if you've improved battery performance through a new internal structure, or improved a machine's efficiency through a new arrangement of components, that can potentially be patentable.

4) Chemical, Pharmaceutical, And Biotech Inventions

Patents are widely used for:

• new chemical compounds,
• new formulations (including combinations and delivery mechanisms),
• industrial biotech processes,
• certain types of biological materials (subject to strict rules).

These areas can get technical quickly, and there are also additional regulatory layers (especially in pharma/health). Getting specialist advice early matters, both to avoid wasting money on an unprotectable concept and to make sure your application is drafted with enough technical detail to stand up later.

5) "Software-Related" Inventions (Sometimes)

This is where many founders get tripped up.

In the UK, you generally can't patent software "as such" (more on exclusions below). But you may be able to patent an invention that involves software if it delivers a technical contribution.

In practice, software-related inventions that can be patentable often involve things like:

• improving computer performance (speed, memory usage, security) in a technical way,
• controlling a physical device or industrial process,
• signal processing, image processing, or data processing with a technical effect,
• network-level innovations (depending on how they're framed and what they achieve technically).

It's less about whether it uses code, and more about whether it solves a technical problem in a technical way.

What Can't Be Patented (Common UK Exclusions You Need To Know)

Even if your idea is original and commercially valuable, it might still fall outside what patent law protects.

The UK rules exclude certain categories, particularly where the "invention" is not considered technical enough.

1) Discoveries, Scientific Theories, And Mathematical Methods

If you've discovered something that already exists in nature (for example, a naturally occurring substance), that discovery alone is usually not patentable.

However, applications of discoveries can sometimes be patentable - for example, a new industrial method that uses the discovery in a practical way.

2) Aesthetic Creations (Purely The Look Of Something)

If what's new is mainly the visual design (shape, pattern, look), patents usually aren't the best fit. That's more in "design right" territory.

This comes up a lot in product businesses where the differentiator is the look and feel rather than a technical feature.

3) Schemes, Rules, Or Methods For Doing Business

A "business method" by itself is usually not patentable - for example:

• a new pricing model,
• a way of structuring subscriptions,
• a method of selling or marketing,
• a set of rules for running a competition or marketplace.

That doesn't mean you're stuck with no protection. Often the better strategy is a mix of contracts, confidentiality, branding, and operational control.

4) Computer Programs "As Such"

As mentioned above, a standalone app idea is often not patentable in the UK if it's essentially software doing "normal" data processing or automating a business process.

Where businesses can go wrong is spending time and money on a patent application before properly assessing whether there's a technical contribution. If your core value is really your codebase, product content, and brand, you may be leaning more on copyright, trade marks, and contractual controls - including making sure your IP is owned by the right entity via an IP Assignment (especially if you use contractors or external developers).

5) Presentations Of Information

Things like the layout of information, dashboards, or the way data is displayed are often excluded unless there is a technical effect beyond the information itself.

6) Methods Of Medical Treatment (With Some Exceptions)

In the UK, methods of treatment of the human or animal body by surgery or therapy, and diagnostic methods practised on the body, are generally excluded from patentability.

However, products used in those methods (for example, substances, compositions, medical devices) can often still be patentable.

A Quick Warning About "Public Disclosure"

Even if your idea is patentable in theory, you can lose the ability to patent it if you disclose it publicly before filing.

Public disclosure can include:

• launching your product,
• posting technical details on your website,
• presenting at an event,
• publishing a demo video that reveals how it works,
• sharing it with manufacturers or investors without proper confidentiality protections.

This is one of those areas where getting advice early isn't just "nice to have" - it can be the difference between having a patent option and losing it permanently.

Is Your Invention Patentable? A Practical Checklist

If you're trying to sanity-check your invention before speaking to a patent attorney, here are the key questions to work through.

1) Is It Actually New?

"New" means it hasn't been made available to the public anywhere in the world.

That's why novelty searches matter. It's not only about what your competitors are selling - it's also about patents, academic papers, technical forums, and older products.

If something similar exists, you may still have a patentable improvement, but you'll want clarity on what exactly is new in your version.

2) Is It Inventive (Or Would It Be Obvious)?

This is where a lot of ideas fall down.

An invention can be "new" because nobody bothered to do it before, but still be "obvious" once you see the existing technology.

Ask yourself:

• Would a skilled person in this field think, "of course, that's the next step?"
• Is the improvement simply swapping materials or changing dimensions in a predictable way?
• Does your invention solve a long-standing technical problem in a non-obvious way?

3) Does It Have A Technical Effect?

This is especially important for software and "smart" products.

Technical effects can include (depending on the facts):

• improved speed, efficiency, or reliability of a system,
• improved security at a technical level,
• controlling a physical process or device,
• processing signals/images with a measurable technical outcome.

If the effect is mainly commercial (e.g. "it increases conversions" or "it improves user engagement"), that's usually not enough for a patent on its own.

4) Can You Explain It Clearly Enough To File?

This part surprises people: to get a patent, you need to disclose your invention clearly enough that someone skilled in the field could reproduce it.

If you only have a concept sketch, you might not be ready to file. But if you wait too long and disclose it publicly, you risk losing novelty.

That tension is why many businesses plan their filing strategy alongside product development - not after launch.

5) Do You Actually Own The Invention?

Ownership is a practical business risk that often gets overlooked.

If the invention was created by:

• a contractor,
• a freelancer,
• a co-founder who later leaves, or
• a collaborator in another business,

?you should be careful about assuming "the business owns it". IP ownership can depend on the contracts in place and the working relationship.

This is why it's smart to lock down IP and confidentiality upfront through the right agreements, instead of trying to untangle it later when there's real revenue (or an investor) on the line.

How Do You Patent Something In The UK? (Steps, Timelines, And Common Pitfalls)

Patenting is a process, not a single form - and the way you handle the early steps can have a huge impact on the strength of protection you end up with.

Step 1: Keep It Confidential While You Explore Options

Before you pitch widely or send technical documents to manufacturers, make sure you've got confidentiality protections in place.

In many cases, a properly drafted Mutual NDA is useful where both sides will share sensitive information (for example, if you're discussing joint development).

Step 2: Do A Patentability And Prior Art Search

This step helps you understand:

• whether similar inventions already exist,
• what angle might still be protectable, and
• how narrow or broad your claims might need to be.

It's also a cost-control step - better to find out early if your invention is unlikely to succeed than to spend months drafting and filing an application that gets rejected.

Step 3: Decide On Your Filing Strategy (UK Only vs International)

You might start with a UK filing, but many businesses quickly consider wider protection depending on:

• where you will manufacture,
• where you will sell,
• where competitors are based, and
• where investors expect protection.

There are international routes (including via the PCT system) that can help you delay some costs while preserving options - but this is one of those areas where tailored advice matters, because the "best" strategy depends heavily on your timeline and budget.

Step 4: Draft The Patent Application Carefully (This Is Not A Template Job)

The quality of the drafting can make or break your patent.

Your patent is defined by its claims (the legal boundaries of protection). If the claims are too narrow, competitors can design around you. If they're too broad, you may not get granted, or the patent may be vulnerable later.

This is also where businesses can accidentally disclose the wrong details (or not enough details), which can undermine enforcement.

Step 5: File And Go Through Examination

Once filed, there are several stages (including search and examination). Expect back-and-forth, and don't be surprised if the examiner raises objections - that's common.

Timelines vary, but patents are not "instant protection." You can often say "patent pending" after filing, but enforceable rights usually come later once granted.

Step 6: Think About Enforcement And Commercial Reality

A patent is only as useful as your ability to use it commercially.

That might mean:

• licensing the technology to others,
• using it to deter copycats,
• raising investment with a stronger IP position, or
• protecting margins by limiting direct competitors.

But enforcement can be expensive. That's why many businesses plan a broader IP strategy, not just patents - your brand protection, contracts, and ownership structure all matter here too.

Where your business has multiple IP assets (brand, code, inventions, content), it's often worth getting structured advice from an Intellectual Property Lawyer so you're protected from day one and not relying on assumptions.

Key Takeaways

• In the UK, a patent generally protects a technical invention that is new, inventive, and industrially applicable.
• Common patentable areas include products, devices, manufacturing methods, and certain software-related inventions that create a real technical effect.
• Many valuable ideas still can't be patented - including business methods, presentations of information, and computer programs "as such".
• Public disclosure before filing can destroy novelty, so confidentiality and timing matter more than most people realise.
• Patent ownership isn't automatic - if contractors or collaborators contributed, you may need proper documentation (such as an IP Assignment) to ensure the business owns the invention.
• A strong IP strategy often combines patents with brand protection (like a Trade Mark) and practical contractual protections (like an NDA).
