Nullity Proceedings

Plea for annulment of an issued patent

You would like to use a method or an object, but there is already a registered patent standing in your way?

A patent can be removed from the register of the German Patent and Trademark Office and an action for annulment is required. Anyone can submit a plea for annulment.

Whether or not a patent can be annulled must be individually examined by a patent attorney or a lawyer with a detailed examination. This is one of the service we can offer you.
