Granted European patents can be opposed. During the opposition procedure before the European Patent Office, a decision on the validity of the patent is taken. If you would potentially be affected by someone else’s patent, you can initiate such an opposition. Alternatively, NLO can provide advice on the (in)validity of the patent or application of another party or assist you in the defense of your granted European patent when this is opposed by another party. Click below for more information on how NLO can assist you, in case you would become involved in a patent-related conflict.
