Patent term extensions in Russia

2.12.2021 – 4.30 pm EET

Come and join us for a live webinar to learn about how to obtain a patent term extension (PTE) covering Russia for pharmaceutical products or agrochemicals that require a marketing authorization. The webinar will be held by our European Patent Attorney Satu Lehesranta on 2 December at 4.30 pm EET. The webinar is free of charge and all registrants will receive a link to the recording after the webinar.

The PTE is an extension to a patent right to compensate for the time required to demonstrate that the pharmaceutical product or agrochemical is safe and effective, and so it is the Russian counterpart for the European supplementary protection certificate.

In this webinar you will hear about recent changes in the Russian PTE practice and how to successfully obtain a PTE.

The Russian practice concerning PTEs has recently become much stricter; instead of a true patent term extension, Russia grants a supplementary patent with claims limited to the product for which authorization has been obtained. This may currently require very strict claim amendments, and the Russian office may reject a PTE request if the claims are too broad or if the active agent is not sufficiently described in the patent.

At the same time, the Eurasian Patent Office (EAPO) grants PTEs for Eurasian patents covering Russia, with a very different approach.
