Further shortened ISR lead time introduced as from 1 January 2023


23 January, 2023

The Visegrad Patent Institute constantly works on user-friendly initiatives to become the “PCT authority next door” for applicants filing under the PCT in the Visegrad countries, Serbia and Lithuania.

The Visegrad Patent Institute serves its applicants by ensuring their early access to international search reports that help better evaluate their patenting chances on the territories of the relevant markets.

The first step was to reduce the 3- or 9-month ISR lead times set by the PCT by 1 week as from 1 June 2021. Due to this initiative and according to WIPO’s data, the Visegrad Patent Institute became the fastest PCT authority in issuing international search reports and written opinions worldwide in 2021.

The experience gained with the expedited international search reports made it possible to further reduce the ISR lead times in 2023, without making any compromise in respect of the quality of international search reports.

The ISR lead times in cases where no priority is claimed for international applications filed as from 1 January 2023 were cut to 8 months. In all other cases, the Visegrad Patent Institute maintains the previous practice with 1-week shorter lead time.

The new initiative of the Visegrad Patent Institute may further help its applicants in their efforts to gain a more favourable position on the markets they intend to enter.

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.
