On April 26th, 2012 Moldova has left the Eurasian Patent Organization. Granted Eurasian patents as well as International patent applications comprising a designation of Moldova for a Eurasian patent as well as a filing date before April 26th, 2012 remain unaffected. With respect to later international applications, only the national designation of Moldova outside of the Eurasian Patent Organization remains.

The Eurasian Patent Organization has come into effect in 1995. Member states are the former CIS states Armenia, Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan, the Russian Federation, Tajikistan and Turkmenistan, but not the Ukraine, Georgia, Uzbekistan, and henceforth Moldova.

The Eurasian patent features essential advantages compared to alternative national patent rights. In particular, the language of the proceedings at the Eurasian Patent Office domiciled in Moscow is exclusively Russian. Furthermore, the granted Eurasian patent does not have to be validated in the designated countries. The Eurasian patent applies to all contracting states uniformly. A translation into the national languages of the different countries is not required such that the expenses are limited.
