Finding reasons for nullity 

Nullity Search

In case the opposition period has lapsed and there are no pending opposition proceedings, an action for nullity can be filed. 

As a ground for nullity, for example, a lack of patentability can be asserted, for instance relating to technical features which have already been disclosed in another patent.

It is our task to find documents supporting the above-mentioned reasons and to equip you properly for the proceedings.
