Patent

The patent ensures legal protection of inventions by granting a better position to the owner of invention compared to that of rivals in the market of products and technology.

The owner of invention has an exclusive right to exploit the inventive technical solution devised in the patent application, but the period and the territorial validity of patent protection are not unlimited. The patent protection is valid up to 20 years started from the day on that the patent application was filed and solely in the countries where the protection was granted.

Hungarian patent may be obtained by national⁣ or European⁣ application or by an application submitted in the framework of the Patent Cooperation Treaty (PCT⁣) provided that the application and the invention comply with requirements set out in laws and regulations.

An international (PCT or European) application can be filed from a Hungarian national application, no later than 12 months from the priority of the national application. The granting of an international application is different according to the PCT and European procedures:

  • In the case of a European application, if the application complies with the legal requirements, the European Patent Office (EPO) will grant the application. Within 3 months of the grant, protection can be validated in the countries of the European Patent Convention through a simple national validation procedure.

 Both types of international applications can be initiated by submitting an application to the HIPO.
