On 5 May 2025, Kazakhstan recognized the Eurasian Patent Organization (EAPO) as an International Searching Authority (ISA) under the Patent Cooperation Treaty (PCT). This recognition allows applicants from Kazakhstan to choose the EAPO as their ISA for conducting international patent searches within the PCT framework.

As an ISA, the EAPO enables cost-effective and efficient international searches for those conducting patent procedures in Russian. The EAPO has been functioning as both an ISA and an International Preliminary Examining Authority (IPEA) under the PCT since 1 July 2022. The patent offices of eight EAPO member states have recognized the EAPO as a competent ISA and IPEA.
