An invention is a product or a process that provides a new way of doing something, or offers a new technical solution to a problem. It requires specialized knowledge and skilfulness of the inventor. However, it can easily and quickly be imitated or reproduced when unprotected, causing damage to the legal owners.

A Patent is a title of protection granted to the inventor or beneficiary of any invention which is

  • New - that means that, prior to the date of filing of an application for protection, the invention was not already known to the public in any form (written, oral or through use). Consequently, it is advisable for the inventor to file the application first and make the new idea public afterwards,
  • Involves an inventive step - that means that in the light of what is already known to the public, the new idea is not obvious to a person with average knowledge of the technical field, and
  • Susceptible to industrial application - that means that it can be made or used in any kind of "industry", including agriculture, as distinct from purely intellectual or aesthetic activity.

The owner of a Patent is granted the exclusive right to make full use of it and, without the Patent owner's consent, the invention cannot be commercially made, used, distributed or sold.

The Industrial Property Organisation ( is the only official body for filing a Patent application in Greece. A Patent is protected from the date of its application and its duration in Greece is 20 years, provided that the proper annuities are paid in time (from the 3rd year of the application date).

The filing of the International Patent application aims at the simultaneous (through a single application) seeking of an invention protection in each of a large number of countries all over the world under the Patent Co-operation Treaty (the "PCT"). The International Patent application has, from the date of application, the effect of a National Patent application in those PCT Contracting States which the applicant designates. It has the effect of a European Patent application in those among the PCT Contracting States which are also party to the European Patent Convention, provided that they are designated for a European Patent.

The applicant needs to file a single International Patent application with the International Bureau in Geneva ( Alternatively, he can file it with his national Patent Office which will act as a PCT "Receiving Office" or, if he is a national or resident of a country party to the European Patent Convention, with the European Patent Office ( in Munich, if permitted by his national law.
