Patents

Last updated: 20 April 2017

You can use a patent to protect an idea. It gives you the right to take legal action against anyone who makes, uses, sells or imports it without your permission.

A patent can also help you make money from your idea. For example, it would mean you could license your idea for a fee – if someone else was interested in manufacturing and selling it.

To be granted a patent, your idea must be all of the following:

  • something that can be made or used
  • new
  • inventive – not just a simple modification to something that already exists

They can only protect your idea for up to 20 years and you'll need to pay a fee to renew your patent every year.

Visit GOV.UK for the full list of information about patents.

This information applies to the UK only. Find out how to protect your intellectual property abroad.

Other ways of protecting your idea

Applying for a patent is:

  • complicated – only 1 in 20 applicants get a patent without professional help
  • expensive – with professional help, applications typically cost £4,000
  • a long process – it usually takes 5 years
If you get a patent, you'll also have to pay to renew it each year and pay the costs of legal action if you need to defend it.

This means you might want to consider different ways of protecting your idea, such as:

  • non-disclosure agreements to keep it a secret before launch – this can provide enough protection if your product is likely to sell for only a short time
  • trade marks – if you can create a brand and be first to market
  • design rights – if how your product looks (rather than how it works) is important and innovative

Before applying for a patent, you should check whether one already exists for your idea. You can search for existing patents using the following:

Renew a patent

You must renew your patent on the fourth anniversary of when you filed for it. You then need to renew every year near the 'due date' – the last day of the month in which you first filed.

To avoid late payment fees, you'll need to renew your patent up to 3 months before or within 1 month after the due date. You can renew your patent for up to a maximum of 20 years.

Visit GOV.UK to renew a patent and find out what the renewal fees are.

You must tell the Intellectual Property Office if details in the patents register are wrong or you need to change them.
