Excuse of delays due to COVID-19 pandemic

The Visegrad Patent Institute (VPI) adopts the interpretation of current situation relating to the COVID-19 pandemic taken by the International Bureau of the World Intellectual Property Organisation (WIPO).

In line with the recommendations made by the WIPO, the VPI considers the pandemic to be a „natural calamity” and therefore will treat requests under PCT Rule 82quater.1 to excuse delays in meeting time limits favourably. Applicants are not required to submit further evidence of disruption caused by the pandemic in their Rule 82quater.1 requests.

We welcome our Serbian Users – Memorandum of Understanding signed between the Intellectual Property Office of Serbia and the Visegrad Patent Institute

A Memorandum of Understanding (MoU) was signed between the Intellectual Property Office of the Republic of Serbia (IPOSR) and the Visegrad Patent Institute (VPI), furthermore, the International Bureau of the World Intellectual Property Organization was duly notified thereon in July 2020.

In the MoU, IPOSR declares that the VPI is a competent International Searching Authority (ISA) and International Preliminary Examining Authority (IPEA) for international applications filed under the Patent Cooperation Treaty (PCT) by Serbian nationals and residents (Serbian Users).

The appointment to act as ISA and IPEA for Serbian Users is a great honour for the VPI. The signatories to the MoU expect that this new possibility offered for Serbian Users can contribute to the development of the knowledge- and innovation-intensive industries in Serbia, and could have a positive effect on involving research institutions and universities into the innovation ecosystem of the region. Additionally, the MoU opens up a new area of cooperation that can further strengthen the already existing network and good relationships between the industrial and intellectual property offices of our region.

The MoU enters into force on 1 September 2020. As from that date, Serbian Users can choose for their international applications under the PCT the VPI as ISA and IPEA.

We look forward to receiving international patent applications from our Serbian Users!


The Visegrad Patent Institute (VPI), which started operation on July 1st 2016, is an intergovernmental organization for cooperation in the field of patents established by the four Visegrad countries: the Czech Republic, Hungary, the Republic of Poland and the Slovak Republic (V4 countries).

The VPI was appointed as an International Searching Authority (ISA) and International Preliminary Examining Authority (IPEA) under the Patent Cooperation Treaty (PCT) in order to attain a wide range of important objectives at various (global, European, regional and national) levels.

The VPI fills a territorial gap within the global system of the PCT, acting as an International Authority for Central and Eastern Europe. It is noteworthy that in WIPO, the Group of Central European and Baltic States was the only regional group without a functioning International Authority under the PCT. The VPI also makes up for the missing link in the network of European PCT authorities. Therefore, the VPI is intended to support the development and usefulness of the PCT system by adding further competent resources to those already available, especially in respect of a region currently without its own International Authority in place.

The structure of the VPI follows the existing successful model of the Nordic Patent Institute. Thus, the governance of the VPI as an intergovernmental organization is ensured by its Administrative Board composed of the representatives of the Contracting States, while the VPI’s Secretariat, headed by the Director, is responsible for the organization, day-to-day management and administrative support of the VPI’s work.
