If you create a new invention, you should consider protecting it by a patent.
A patent gives you the right to stop people from making, using, importing or selling your invention without your permission. A granted patent can remain in force for up to 20 years, if you renew it regularly. A patent also allows you to license others to use your invention which can generate royalties and provide an important source of revenue for your business.
There are strict rules that determine what can and can't be patented. A patent may not always be the best way for you to protect your invention.
