Patents – Requirements

What is a patent?

A patent protects new inventions and covers how things work, what they do, how they do it, what
they are made of and how they are made. It gives you the exclusive right to make, use and sell the
invention in the United Kingdom.

Requirements for patent protection

You need to think carefully about the following before applying for a patent for your product or

* Is your invention functional or technical?
Your invention must relate to how something works, what it does, what it is made of, or how it
is made.
* Is your invention new?
You must not have made your invention public in any way, anywhere in the world, before you apply
for a patent for it. Conversations with patent agents, solicitors or our staff are confidential,
so will not make your invention public.
* Is there an inventive step?
Your invention must not be obvious to someone with a good knowledge of the subject.
* Does your invention have an industrial use?
Your invention must be capable of being made or used in an industry. It must work in a way which
meets established physical laws, for example, you cannot get a patent for a perpetual-motion
* Your invention must not be:
a scientific or mathematical discovery, theory or method
a literary, dramatic, musical or artistic work
a way of performing a mental act, playing a game or doing business
the presentation of information, or some computer programs

against public policy or morality.

If your invention meets these requirements, you may want to consider applying for a patent.
