APPLY FOR A PATENT IN THE UK

A patent is an intellectual property right granted by the UK government that gives you the exclusive legal right to make, use and sell your invention within a specific territory for a limited period. It confirms you are the legal owner of your product, design, or invention and allows you to prevent others from copying or profiting from it without your permission.

​

A patent is a valuable business asset that can be sold, licensed or used to attract investors. Patents are crucial for inventors, entrepreneurs and businesses developing new technologies or products.

​

A PATENT APPLICATION INCLUDES

​

• A written description explaining how the invention works

• Drawings that illustrate the invention

• A list of claims defining the unique technical features

• An abstract summarising the invention’s key aspects

​

Patents make it illegal for anyone except the owner (or someone with permission) to make, use, import or sell the invention in the country where it’s granted. They provide commercial leverage, protect research and development investment and increase credibility with investors.

​

WHAT DOES A PATENT PROTECT

​

Patents protect new and inventive products or processes that offer a technical or functional advancement. They focus on how things work, how they are made and what they are made of. Examples include electronics, medical devices, engineering systems, manufacturing methods and consumer products.

​

TO APPLY FOR A PATENT, YOUR INVENTION MUST BE :

​

• New – not previously disclosed publicly

• Inventive – not an obvious development of existing technology

• Capable of industrial application – can be made or used in any kind of industry

• Technically contributive – provides a real technical benefit or improvement

​

YOU CANNOT FILE A PATENT FOR :

​

• Scientific or mathematical theories or discoveries

• Literary, musical or artistic works

• Business or mental methods

• Methods of medical treatment

​

HOW LONG IT TAKES TO GET A PATENT

​

A UK patent application usually takes up to five years from filing to grant. The process can be accelerated for an additional fee, but missing any deadlines can result in your application being terminated.

​

HOW LONG A PATENT LASTS

​

A UK patent lasts for 20 years from the filing date, provided annual renewal fees are paid to the Intellectual Property Office (IPO). If renewal fees are not paid, the patent will lapse and your legal protection will end.

​

COST TO FILE A PATENT IN THE UK

​

To file a patent in the UK, the cost can range from :

​

• Around £400 in IPO official fees if you file the application yourself

• Between £2,000 and £6,000 if you hire a patent attorney or agent to draft and file it professionally

 

Although it’s possible to file independently, using a qualified patent professional can significantly improve your chances of success and help ensure your rights are robust and enforceable.

​

ARE PATENTS WORTH THE MONEY

​

The value of a patent depends on several factors including :

​

• The quality of the intellectual property

• The technical strength and clarity of the claims

• Your commercial objectives and resources

• The competitive landscape

​

A poorly written or weak patent can be as worthless as having no patent at all. However, a strong, well-drafted patent can protect your invention, attract investors and provide ongoing financial return through sales or licensing.

 

BENEFITS OF FILING A PATENT

 

• A granted patent establishes you as the legal owner of the invention

• Provides the right to take legal action against anyone copying your technology

• Allows you to sell or license your invention for income

• Builds trust with investors and manufacturers who prefer working with protected innovations

​

In short, filing a patent gives you control over your invention and enhances its commercial value.

​

THE PATENT APPLICATION PROCESS (STEP BY STEP)

​

1. PREPARE YOUR PATENT APPLICATION : write a clear technical description, include detailed drawings, claims and an abstract.

2. FILE YOUR APPLICATION WITH THE UK IPO : submit Form 1 and your completed patent documents to the UK Intellectual Property Office. You’ll receive a filing receipt confirming your filing date and application number.

3. REQUEST A PATENT SEARCH : within 12 months, request an official search. The IPO will examine your application and issue a search report highlighting similar patents or publications.

4. PUBLICATION OF THE APPLICATION : around 18 months after filing, your patent will be published publicly in the Patents Journal, making the invention visible worldwide.

5. SUBSTANTIVE EXAMINATION : within 6 months of publication, request a substantive examination. The examiner will assess whether your invention meets the legal criteria for patentability.

6. GRANT OF PATENT : if your application satisfies all requirements, the IPO will issue an Intention to Grant letter and then officially grant the patent. A certificate will be issued and details published in the Patents Journal.

​

FILING INTERNATIONAL PATENTS

​

After you file a UK patent, you have 12 months to apply for protection in other countries. You can do this via :

​

• THE EUROPEAN PATENT CONVENTION (EPC) – one application covers up to 39 European countries.

• THE PATENT COOPERATION TREATY (PCT) – a single international patent application covering up to 157 countries.

• DIRECT NATIONAL FILINGS – applying directly in each country of interest.

​

Each route varies in cost and duration, but all allow you to expand protection beyond the UK.

​

USING A PATENT ATTORNEY

​

While you can file a patent yourself, it’s strongly recommended to use a qualified UK patent attorney. They ensure your claims are legally sound, comprehensive and resistant to challenges.

​

Patent attorneys typically have technical degrees and legal training and are qualified to represent you before the UK IPO and international authorities. Investing in expert help can save you thousands later in legal disputes or rejected applications.

​

BEFORE YOU FILE : CONDUCT A FREE PATENT SEARCH

​

Before applying for a patent, always conduct a patent search to check if your idea already exists. Free databases include :

​

• UK IPO IPSUM

• ESPACENET (EUROPEAN PATENT OFFICE)

• WIPO PATENTSCOPE

• SEARCHABLE PATENTS JOURNAL

​​

You can also visit a Patent Library (available in major UK cities including Leeds, London, Manchester and Birmingham) for professional help with searches.

​

WHEN SHOULD YOU APPLY FOR A PATENT

​

You should file a patent once your invention is technically and commercially defined. Filing too early can result in weak protection if your idea is still undeveloped. Filing too late can risk public disclosure that invalidates your claim. Ideally, file when :

​

• The design and functionality are finalised

• You can clearly describe what makes it new and inventive

• You are ready to commercialise or seek investment

​

A PATENT IS ONLY AS STRONG AS ITS SPECIFICATION

​

The strength of your patent depends on the technical richness and precision of your application. A vague or broad patent can easily be challenged or circumvented. A detailed, technically rich application creates a strong legal barrier that enhances commercial value and investor confidence.

​

If your goal is to apply for a patent in the UK, protect your invention effectively and secure future commercial opportunities, make sure your application is drafted and filed correctly.
