If you have an invention, for example a new product or process, you may be able to protect it by filing for a patent. A patent will allow you to protect your invention and prevent other people benefiting from your success without permission. If you decide to protect your invention, you should consider which means of protection is the most suitable.
Patents are territorial and must be filed in each country where protection is sought. No one applies for a patent in all countries of the world, as it is much too expensive. You should determine the countries in which your most important markets are located and where you think you can exploit your product to make a profit.
