If you’ve dreamed up a new invention, gadget, or ground-breaking process, protecting your idea is vital to long-term success. In the UK, the best way to secure exclusive rights over what you’ve created is by applying for a patent-giving you the legal tools to stop others from copying, selling, or using your invention without permission.

But the patent application process can seem daunting, especially if you’re new to intellectual property. The good news? With the right preparation and an understanding of each step, you can confidently apply for patent protection and set your business or creative venture up for growth. In this guide, we’ll walk you through exactly how to apply for a patent in the UK-breaking down what you need, key milestones, and expert tips to get it right.

Ready to protect your invention? Let’s get started.

What Is a Patent (And Why Does Patent Protection Matter)?

A patent is a type of intellectual property (IP) right. It protects inventions-whether that’s a new product, process, or technical solution-that are new, inventive, and capable of industrial application. If granted, a patent gives you the exclusive right to use, make, sell, or license the invention, usually for up to 20 years.

This kind of legal protection is vital for inventors and businesses looking to:

  • Stop others from copying or exploiting their new ideas without consent
  • Create value for their business by licensing technology or raising investment
  • Defend against competitors and secure a commercial advantage

Without patent protection in place, competitors may be free to use your invention-costing you valuable revenue and growth opportunities.

Who Handles Patent Registration in the UK?

All patent applications in the UK are managed by the UK Intellectual Property Office (IPO). This government agency assesses applications and issues legally-binding patents if your invention meets the necessary criteria. Most inventors apply for their first patent directly via the UK IPO’s online application system, though you can also apply via post using official forms.

Understanding this process, and making sure every step is followed correctly, is essential-mistakes or missing documents could lead to costly delays or even rejection of your application.

How Do I Know If My Invention Can Be Patented?

Not every idea can become a patent. The UK has specific requirements (under the Patents Act 1977) to determine whether an invention is “patentable”. Your invention must be:

  • New – Not previously disclosed anywhere in the world (even by you!)
  • Inventive – Not obvious to a person skilled in the relevant technical field
  • Capable of Industrial Application – It must be usable in some kind of industry (not purely abstract or theoretical)

There are also exclusions-certain things like scientific theories, mathematical methods, artistic works, or business methods generally can’t be patented. If you’re unsure about your invention’s eligibility, it’s smart to speak to an intellectual property lawyer early on.

Step-By-Step: How to Apply for a Patent in the UK

Applying for a patent isn’t just one form and a fee-it’s a structured process, designed to make sure only genuine, novel inventions get protection. Let’s break it down, step by step.

1. Secure Confidentiality Before You Apply

Don’t share your invention publicly-until you’ve filed your application! Even showing a prototype to potential investors, manufacturers, or partners could jeopardise your chances by destroying “novelty”. Consider having anyone you speak with sign a Non-Disclosure Agreement (NDA) before discussing your idea.

2. Check Existing Patents (Patent Search)

Before you spend time and money applying, check if your invention really is new. Search patent databases (such as the UK IPO database, or international portals like Espacenet) for similar inventions.

Ask:

  • Is my invention already patented or published by someone else?
  • If similar inventions exist, does mine offer a real technical improvement or advantage?

If you find a conflict, it may save you the effort of a doomed application-or let you tweak your idea.

3. Prepare Your Patent Application Documentation

A UK patent application must include several key documents:

  • Patent Application Form (Form 1) – Used to officially request a patent from the IPO. Downloadable from the UK IPO website (or you can complete this step online).
  • Detailed Description (Specification) – An in-depth technical description of your invention, explaining how it works. This needs to be clear, so that someone “skilled in the art” could replicate your invention from your description. Visual drawings or diagrams are highly recommended to aid clarity.
  • Claims – Perhaps the most important part. Claims are formal statements that define the unique, novel aspects of your invention, and set the legal “boundaries” of what your patent actually covers. Care and precision here are essential-overly broad or vague claims can lead to rejection, but too narrow and competitors may work around you.
  • Abstract – A concise summary of the main technical features of your invention.

High-quality claims and clear, thorough documentation are the hardest part of a successful patent application. Professional support is highly recommended-patent lawyers or patent attorneys can save you a lot of trouble here.

4. File Your Patent Application

Once your documentation is ready, you’re set to submit your application. You can do this:

  • Online via the UK IPO Portal – Fastest, easiest, and creates an instant digital record.
  • By Post – Using the official UK Patent Office forms.

On submission, you’ll receive an acknowledgement and an official filing receipt with a filing date. This “priority date” secures your spot in line-crucial if there are competing filings on similar inventions.

Make sure you track and save all documentation and receipts, as they may be needed if issues arise later.

5. Request a Patent Search

A patent search is an official investigation (conducted by the IPO) to see if there is any prior art that could undermine your application’s claims of novelty and inventiveness. You must request this search within 12 months of submitting your application (or earlier, if claiming priority from a previous application). We strongly recommend making the request at filing time-you’ll get faster feedback about whether your invention is truly patentable.

To request a search you’ll need:

  • Form 9A (Request for Search)
  • The official search fee (payable to the IPO)

The IPO will issue a search report identifying any existing technologies or patents that may affect your application’s success. Review this carefully-if something crops up, you may need to amend your claims or documentation.

6. Wait for Preliminary Examination

Within a few months, the IPO will conduct a preliminary examination of your application. They check that all paperwork is present and in order, that your invention appears to be something that could in principle be patented, and that your claims are intelligible and supported by the description.

If there are issues (such as missing documents or unclear claims), you’ll get an opportunity to fix and resubmit.

7. Publication of Your Application

Eighteen months after your earliest filing date (priority date), your patent application will be published online by the IPO. This makes your invention public-so while you don’t have the rights of a granted patent yet, you can more confidently start discussing, pitching, or marketing your product.

8. Request Substantive Examination

Within 6 months of publication-or up to 3.5 years from your original filing date, whichever is sooner-you must request a full substantive examination (and pay the examination fee). This is a detailed technical review, where IPO examiners check that your invention truly meets all criteria for patentability.

  • Is your invention genuinely new, inventive, and useful?
  • Are your claims properly supported? Are they clear and workable?
  • Are there any exclusions (e.g., scientific methods, artistic works)?

If issues are raised, you’ll have the opportunity to respond-sometimes by amending your claims or adding clarifications. It’s not unusual for several rounds of correspondence before the examiner is satisfied.

Tip: Getting professional help to draft or amend your claims can make this process much smoother. A patent expert can often resolve objections more efficiently than going it alone.

9. Patent Granted (Or Refused)

If your application passes examination (and all fees are paid), the IPO will grant you a patent-a powerful legal right to stop others copying or profiting from your invention in the UK. Your patent will be published in the Patents Journal and can last for up to 20 years, provided you pay the annual renewal fees.

If your application is refused, you’ll be advised of the reasons-there may still be the chance to amend or appeal.

How Much Does It Cost to Apply for a Patent in the UK?

Government fees for the patent process (at each stage) are relatively modest: a basic application can be filed for £60–£90, with additional costs for searches, examinations, and renewals. However, the real cost often comes from preparation.

Thorough searches, drafting clear claims, and handling any objections or amendments can involve further costs-especially if you use a professional (which we strongly recommend). A typical full patent application prepared by a patent specialist may cost several thousand pounds. But remember: strong patent protection is an investment that can protect your innovation and help your business thrive.

Can I Apply for a Patent by Myself, Or Should I Use a Patent Lawyer?

It is possible to apply for a patent yourself. However, this is a complex legal process-unclear claims or mistakes can lead to rejection, or leave you with a weak patent that’s easily worked around. For most inventors and businesses, having a patent lawyer or patent attorney prepare your application is well worth the extra investment.

A patent law expert can:

  • Help craft strong claims and avoid common applicant mistakes
  • Conduct thorough prior art searches
  • Advise if your invention is actually patentable
  • Amend documentation or respond to examiner objections
  • Guide you on international patent options if you want protection abroad

Many businesses also use an IP Health Check to review their full intellectual property situation before filing.

How Can I Protect My Invention While Waiting for a Patent?

Patent applications take time-often several years. Here’s how to stay protected while you wait:

  • Use confidential contracts (NDAs) when discussing or pitching your invention
  • Mark marketing materials as “patent pending” to warn off competitors
  • Keep documentation of when you developed your invention to defend your rights if challenged

On publication (after 18 months), you gain some provisional rights-if others start using your invention during this period, you may later be able to claim compensation once a patent is granted.

What About International Protection-Is a UK Patent Enough?

A UK patent only covers the UK. If you need protection overseas, you’ll need to apply in each country of interest-or use international routes like the Patent Cooperation Treaty (PCT) to file a single application covering multiple countries. Timing here is critical-usually you must apply internationally within 12 months of your original UK filing date. For more, see our guide to registering intellectual property internationally.
