What is the process for validating a Eurasian patent in the respective countries?
One of the convenient features of the Eurasian patent system is the absence of a separate validation procedure. The patent holder chooses the countries in which the patent should be valid simply by paying the requisite annuities. The annuities are paid to the Eurasian Patent Office, and the patent is automatically valid in all the countries for which the payments have been effected.
And even if a patent is declared invalid in some countries due to non-payment of the annuities, it can be reinstated in any of the countries within three years.
