Revocation

In practice, a competitor’s long-existing patent may become important relatively quickly, be it because of a reorientation of the business or because the competitor initiated a patent infringement proceeding. In the latter case, the period for filing opposition to the grant of a patent has usually expired. However, you may challenge a patent by filing a nullity action for the patent to be revoked in part or in full.

Our attorneys have successfully conducted numerous nullity proceedings for the restriction or full revocation of patents at any level of jurisdiction on behalf of our clients. You can draw on our experience and engineering expertise: we will identify the risks and chances of any potential nullity action and be at your side during pending proceedings as your competent and reliable partner – from the start to the end.
