Apr 26, 2022

If you hold Intellectual property within your business, it is vital to adequately protect it. One of the areas that you may need to consider is that of applying for a patent if your business has an idea or an invention.

According to having a patent in place ‘gives you the right to take legal action against anyone who makes, uses, sells or imports it without your permission.’

You can check what you can patent on the website as not everything can be afforded this type of protection.

If your invention does meet the criteria which mean you can patent it, then you will need to complete a patent application. The process to obtain a patent can be difficult and can cost your business a significant amount of money so you need to be sure that a patent is the right solution before starting.

How to write a patent application

You can find full details of the patent application on the website. There are 4 parts to the application, and you will need to meet specific criteria for each.

If you are writing your patent application yourself then you can refer to the patent factsheets produced by the Intellectual Property Office for information which will assist you with writing your application.

However, because the process is so complicated it is thought that only 1 in 20 successfully obtain a patent without any professional help. So, if you are looking to apply for a patent you may instead want to work with a patent lawyer/solicitor or a patent advisor who will be able to help you write your patent application.

How much does a patent application cost?

Costs can be high for completing a patent application. If you work with a patent lawyer/solicitor or advisor, then it is generally thought it will cost around £4,000 for your application.

You will also incur additional costs as you will need to renew your patent. You will first need to renew your patent on the fourth anniversary of when you filed for it, and you can renew it for a maximum of 20 years. The costs associated with renewing your patent increase every year.

How long does the patent application process take?

As it is so complicated the patent application process takes a long time. You may be looking at up to 5 years to complete the application and obtain a patent.
