HOW MUCH DOES IT COST TO PATENT AN IDEA

YOU CANNOT PATENT AN IDEA

​

You cannot patent an idea on its own. Under UK patent law, an idea must be developed into a fully formed invention before it can be protected. To obtain a patent, your concept must be transformed into a new, inventive and industrially applicable product, method, process or technical solution. The UK Intellectual Property Office (IPO) requires a detailed description explaining how the invention works, how it can be made and how it can be used. Only when your idea becomes a concrete, functional invention with clear technical features does it become eligible for patent protection.

THE COSTS TO APPLY FOR A UK PATENT

​

If you decide to file a UK patent application yourself, your main expenses will be the official fees charged by the Intellectual Property Office (IPO). These are the minimum costs required to start the patent process and keep your application moving through each stage.

​

The Application Fee is £60 if paid on filing or £75 if paid afterwards. Approximately twelve months later, the Preliminary Search Fee becomes due, currently £150, plus the £75 application fee if this has not already been paid. A further twelve months on, the IPO charges a Substantive Examination Fee of £100, which is essential for assessing whether your invention meets the UK patentability criteria.

​

If the IPO grants your patent, you will need to pay annual renewal fees starting from the fifth year to maintain your protection. These increase gradually each year to reflect the value of an active patent.

SHOULD YOU EMPLOY A PATENT ATTORNEY / AGENT ?

​

While UK law does not require you to use a Patent Attorney to draft or file your application, obtaining a high-quality patent without professional support is extremely challenging. Patent attorneys specialise in drafting strong applications, constructing legally sound claims and navigating the complex requirements of patent law and IPO examination.

​

Self-filing may reduce initial costs, but the risk of errors is high. Many DIY patent applications fail due to vague descriptions, weak claims, missing technical detail or an inability to overcome objections raised by the IPO. Once an application is filed, mistakes cannot easily be corrected - and poor drafting can permanently limit the strength and commercial value of your rights.

​

By contrast, a Patent Attorney ensures your invention is properly defined, legally protected and presented in the strongest possible way. Their expertise can significantly increase your chances of securing a defensible patent that provides real commercial advantage.

​

THE COSTS TO EMPLOY A PATENT ATTORNEY / AGENT

​

The cost of working with a Patent Attorney varies according to the complexity and technical depth of your invention. Fees are often structured by the hour, although many firms - including ourselves - offer fixed-fee options for drafting and filing UK patent applications.

​

For simpler inventions, professional patent drafting typically starts from around £2,000. More advanced or highly technical projects can rise to £10,000 or more. These fees are spread across the key stages of the patent process.

The initial stage involves the drafting, compilation and filing of your patent application. Around twelve months later, additional costs arise for processing the Preliminary Search, followed by further costs twelve months after that for handling the Substantive Examination and responding to any IPO objections or queries. A professionally managed application significantly increases your chances of obtaining a strong and commercially valuable patent.

​

WHAT IF YOU CAN’T AFFORD A PATENT ATTORNEY ?

​

If hiring a Patent Attorney is not currently affordable, it may be worth reassessing whether pursuing a patent is the best strategic move at this stage - as a patent is only one element of a wider development and commercialisation process. All successful products require investment in design, engineering, prototyping, testing, validation and marketing - the essential steps for attracting commercial partners or investors.

​

Most licensees, buyers and investors only support inventions with a granted patent or a well-drafted application showing strong potential for approval. A poorly written patent that lacks technical clarity or is easy for competitors to work around holds very little value. However, a well-constructed patent that creates a meaningful barrier to competition can be a powerful commercial tool, increasing your invention’s appeal, value and licensing potential.
