Opposition

With the granting of a patent, a patent application becomes a right of prohibition, the patent. Patentee may prohibit infringing acts by competitors. In case you should be affected by a patent of a third party, we will gladly assist you in attacking the patent, aiming at the revocation of the patent. Reasons which may speak against the maintenance of the patent are violation of formal requirements, lack of novelty or lack of inventive step. It may also be the case that the patent does not disclose the claimed invention in a manner which allows a third person to carry out the invention. In cooperation with our clients we will work out the best arguments and represent them in oral proceedings before the competent panels, in particular Opposition Divisions or Boards of Appeal.

Our experience in opposition cases is also very useful in case your patent is attacked by a competitor.
