Iliana Muhibian

As a step towards harmonising Bulgarian intellectual property legislation with EU legislation, the Bulgarian Trademark Law was substantially amended.

One of the biggest changes was the introduction of proper trademark opposition proceedings in Bulgaria, as it was one of a handful of European countries that did not provide an adequate means of challenging new trademark applications.
