A UK patent is a legal right granted by the UK Intellectual Property Office for a new invention. It allows the owner of the patent (the patentee) to take legal action against others who use their invention without permission. The right has a maximum life-time of 20 years, from the filing date of the patent application. Importantly however, a patent does not give the owner an automatic right to use the invention. The patent owner must still take care to avoid infringing other people’s rights.
To obtain a UK patent you need to apply to the UK Intellectual Property Office (UKIPO).
If the UKIPO decide your invention is patentable, the patent application will be granted. The patent application process can be lengthy, in some cases up to four and a half years, although the procedure can often be accelerated if needed. See below for more details about the procedure.
No. Whether or not you have a patent, you are free to exploit your invention, as long as no one else already has patent rights covering the invention.
However, if you do not have a patent, it can be very hard to stop other people copying your invention.
Note, as mentioned above, that even if you do have a patent, that does not automatically give you the right to use your invention because others may own rights which prevent or restrict your use.
Under the UK Government’s Patent Box initiative, you may be able to reduce the rate of Corporation Tax that you pay on profits derived from products and services which are covered in whole or part by a UK patent.
The potential benefits are significant: a Corporation Tax rate of only 10% on qualifying profits from April 2017. The tax reduction could easily outweigh the cost of obtaining the UK patent and potentially have a far greater financial benefit to your business.

A patent belongs to the inventor, unless they have given the rights to someone else.
Normally, if the inventor is an employee and they make the invention in the course of their work, the rights belong to the employer.
The owner of the patent may license it, allowing others to use the invention. Alternatively, the owner can sell it to someone else.
To be patentable, your invention must meet the following conditions:
It must be new. That is, the invention must never have been made public IN ANY WAY before you apply to the UK Intellectual Property Office.
This means that your invention must not have been published by you or anyone else before the filing date.
Therefore, if you want a patent, you MUST NOT tell anyone about your invention, except in confidence, until your application is filed with the UK Intellectual Property Office.
The invention must involve an inventive step. This means that the invention must not simply be an obvious development of something that is already known.
The invention must be capable of being made or used in any kind of industry, including agriculture. Most inventions satisfy this requirement.
An invention is typically an apparatus, a product, a manufacturing process etc.
Your invention must not fall into an excluded category. This includes works of art, scientific theories, mathematical methods, computer programs and the presentation of information, as such. However, it is still possible to obtain patent protection in these fields, including for computer implemented inventions, in many circumstances. We can give you advice about this.
An application for a UK patent can be made directly by you, or you can authorise a patent agent to act on your behalf. Chartered patent agents are professionally qualified people who are experienced in dealing with the UK Intellectual Property Office and the application procedure.
An application for a UK patent must be made at the UK Intellectual Property Office. Your application must contain:
On receipt of the application the UK Intellectual Property Office gives the application a filing date and a number and sends you a receipt.
Once you have filed your application at the UK Intellectual Property Office you are free to make use of your invention without jeopardising your chances of obtaining a patent, subject to any other people’s rights.
Anything in the public domain before your application's filing date can be used to show that your idea is not new. This includes talks and published documents. Therefore it is important to apply for a patent and obtain a filing date as soon as possible. Other patent applications with an earlier filing date can also affect your application.
After filing you have a year in which to develop your idea and investigate its commercial possibilities before you have to do anything more.
Within a year from the filing date you have to file:
The UK Intellectual Property Office will search for documents showing inventions similar to yours and then issue a search report which lists any relevant documents from around the world that they have found in reference books, scientific journals or other patents. This search gives you an early indication of how likely you are to obtain a patent.
Eighteen months after the patent application was filed it is automatically published and is available for anyone to look at. This is not a granted patent and you cannot sue anyone yet for using your invention.
Within six months of publication you must pay a further fee and request examination. During this detailed examination, the UK Intellectual Property Office may write to you giving reasons why the invention is not new or is obvious. You have a time limit to reply to the UK Intellectual Property Office’s letters and to persuade them that the invention is worthy of a patent. This often involves changing the description of the invention or the claims before agreement is reached, and this can take time.
When the UK Intellectual Property Office agrees that your invention is new and inventive, your patent will be granted. This fact will be published in the UK Intellectual Property Office’s Official Journal and you will be sent a certificate.
The process for obtaining a UK granted patent typically takes from two to four years from the date of the application.
However, by paying some fees early and replying promptly to letters from the UK Intellectual Property Office, it is possible to reduce this time to as little as 18 months.
After four years from the filing date, once granted, annual renewal fees need to be paid to keep the patent in force. These fees increase as the patent gets older.
The fact that you own a patent will often deter competitors from using your invention. It helps to refer to it in your product literature once your patent has been granted. However, if your invention is being used by someone without your consent (infringement) you can obtain an injunction to stop them and claim damages (compensation). This can be done at the High Court, the Intellectual Property Enterprise Court (IPEC) or the UK Intellectual Property Office.
You cannot sue for infringement until your patent is granted. However, once your patent is granted, you may be able to claim damages in retrospect from the date your patent application was published.
A patent granted by the UK Intellectual Property Office only covers the UK.
If you want protection in countries other than the UK, you need to file further applications. Several options are available.
There is no such thing as a "world patent". However, applications for patent protection in several countries at once may be made using the European Patent Convention (EPC) or the Patent Cooperation Treaty (PCT).
The EPC allows you to apply for a patent in up to 39 European countries by filing a single application. A patent is then granted in each of the chosen countries. Further details can be found here.
The PCT is the nearest system to an international patent application, covering most of the industrialised world. One application is filed to cover a number of countries, but the application eventually splits up and proceeds in each country separately. Further details can be found here.
Please get in touch if you would like to discuss these systems and their relative merits in more detail. If a country does not belong to either the EPC or the PCT, you have to file a separate patent application directly in that country.
No. Filing your first application, usually at the UK Intellectual Property Office, establishes your “priority date” in most other countries. You have to decide within twelve months to file applications in other countries and these further applications will be treated as if they were filed on the same date as the first one, provided they relate to the same invention. This is called claiming priority from your first application.
This is useful since it gives you a year to work out whether your invention is commercially viable before spending large amounts of money on patents in other countries.
A few countries will not give you this one year breathing space. If you need patent protection in such countries, you will have to apply at the same time as you make your first (normally UK) application.
A patent attorney can handle all aspects of obtaining a patent, from writing the specification of the invention - the description and the claims - to arguing the merits of the invention with the UK Intellectual Property Office. It is possible to do this yourself without employing a patent attorney.
However, a patent specification is a legal document which can determine the strength of the patent you get and which has to be able to stand up against legal attack.
Employing a patent attorney may increase your costs in the short term, but it is likely to give you a more secure patent.
Patent attorneys are bound by rules of conduct which prevent us from telling anyone about your invention without your consent.
We can advise you on other aspects of intellectual property, such as Trade Marks, Copyright and Designs.
If you want us to write your patent specification, we need detailed information from you about the invention:
We also need your address and phone number so that we can contact you
