Can I patent an idea in the UK?

No, you cannot patent a mere idea in the UK. You can only patent an invention, product, or process that is new, involves an inventive step, and is capable of industrial application.

How do I know if my invention is patentable?

To be patentable, your invention must be new, inventive (not obvious), capable of industrial use, and make a technical contribution. Artistic works, mathematical methods, and discoveries cannot be patented.

How much does it cost to patent an invention in the UK?

Basic costs include an application fee of £60, a search fee of £150 to £180, and an examination fee of £100 to £130. Renewal fees apply from year 5 onwards.

How long does it take to get a UK patent?

The process usually takes 2 to 4 years, depending on the complexity of your invention and any objections raised during examination.

Should I hire a patent attorney?

While not legally required, it’s strongly recommended. A patent attorney can help draft your application clearly and defensibly, increasing your chances of success.

Yes. i1 Design offers professional invention help, including patent search, design development, 3D CAD modelling, and referrals to trusted patent attorneys for filing and legal support.

How to apply for a UK Patent

Step-by-step guide

If you’ve developed a new invention and want to protect it, applying for a patent is a key step. A UK patent gives you the legal right to stop others from making, using, or selling your invention without your permission. This guide outlines everything you need to know about filing a patent application with the UK Intellectual Property Office (UK IPO).

What Is a Patent Application?

To file a patent in the UK, you must submit a patent application, a formal document that fully discloses the technical details and inventive concept of your product or process. A strong application is crucial to securing patent protection.

A standard UK patent application includes the following four elements:

A full written description – Explaining how the invention works.
Detailed drawings or diagrams – Clearly illustrating the technical aspects.
Claims – Defining the unique technical features you want to protect.
An abstract – A brief summary of the invention’s core technical innovations.

Filing a Patent Application with the UK IPO

Once your application is prepared, it must be submitted to the UK Intellectual Property Office (IPO). This involves :

Completing Form 1: Request for Grant of a Patent
Submitting your written specification, drawings, claims and abstract
Paying the required application fee

Upon receipt, the IPO will issue a filing receipt, confirming your application number and the official filing date—both of which are critical for establishing your priority rights.

Step 1: Requesting a Patent Search

Within 12 months of filing, you must request a patent search using Form 9A. This search ensures your invention meets basic legal requirements and checks for existing patents or publications that may affect your claim to novelty and inventiveness.

The IPO will issue a search report, typically within six months, highlighting any similar or conflicting inventions.

Step 2: Patent Application Publication

Around 18 months from the initial filing date, your patent application will be published in the UK Patents Journal. At this point, your application becomes publicly accessible, including all related documents and correspondence.

Step 3: Requesting Substantive Examination

Within six months of publication, you must request a substantive examination using Form 10. This stage involves a detailed legal and technical review by the IPO examiner.

If the examiner raises objections - such as unclear claims or lack of inventiveness, you’ll be given the opportunity to respond or amend the application to overcome these issues.

Step 4: Patent Grant

If your application satisfies all the formal and legal requirements, the IPO will issue a notice of intention to grant. Shortly thereafter :

Your UK patent will be granted
You’ll receive an official patent certificate
The grant will be published in the Patents Journal

Your patent will now be enforceable in the UK, giving you exclusive rights for up to 20 years.

How Long Does a UK Patent Take?

The full patent application process can take up to five years. However, it may be possible to accelerate the process by paying additional fees or using early processing options.

Missing any deadlines can result in your application being withdrawn, so it’s important to track and respond to all IPO correspondence promptly.

Maintaining a Granted UK Patent

Once granted, your UK patent remains valid for 20 years, provided you pay annual renewal fees starting from the 4th year after filing. If you fail to pay these fees on time, your patent may lapse and become unenforceable.

Final Thoughts

Applying for a UK patent is a complex but valuable process that can protect your invention and unlock commercial opportunities such as licensing, investment, or IP sales. Whether you’re a solo inventor or an innovative business, securing patent protection is often a critical step in monetising your ideas.
