A patent is a document giving an inventor a legal, exclusive right to make, use and sell their invention in a particular country or countries, for a given period of time (normally 20 years).
A patent is granted by a state in exchange for the 'complete' disclosure of the invention with the aim of advancing the economy. An invention does not have to be patented, an alternative is to keep the invention a 'trade secret'. For example, the recipe for Coca-Cola is a trade secret and has never been patented or disclosed. The inventor does not have to manufacture the product themselves: patent rights can be sold or licensed to others.
Many countries have gradually put their patent collections into available online databases. Patents can therefore be found by searching the national databases or the common interface Esp@cenet which contains more than 130 million patents from around the world (more than 100 countries). The database is available free of charge.

A single application, once granted, gives protection in all of the countries who have signed up to the treaty. For the moment 24 European countries participates, look here for more information
The Unified Patent Court (UPC) will be a court common to the Contracting Member States and thus part of their judicial system. It will have exclusive competence in respect of European patents and European patents with unitary effect.

A utility model is similar to a patent but is faster and cheaper to obtain than a patent. It can be useful to protect minor inventions with a shorter time of protection
Patents only remain in force with payment of an annual fee. You can check the status of a patent to find out if it has been granted, expired or remains in force.
