Patent Law – Protecting your patents and utility models in Germany.

Patents and utility models allow companies to invest sustainably in researching new technologies, as the resulting competitive advantages can be used exclusively. We support our clients in maintaining this advantage.

For many companies, patents and utility models make up a significant part of the company's value and must therefore be defended by all means. The acquisition of a patent or utility model grants the owner the exclusive right to manufacture, offer, market, use, import or possess the protected product or to use or offer the protected process. The same applies to utility models.

How can we help you?

We take consistent action against patent and utility model infringements. We enforce our clients' cease and desist claims effectively and efficiently by means of warning letters, interim injunctions and border seizures, even at trade fairs where things are particularly urgent. The same applies to the information, destruction and damages claims that arise in the event of a patent or utility model infringement. This is the only way to protect your patents and utility models effectively and sustainably.

We also advise our clients on the granting, acquisition or sale of licenses for patents and utility models. We draft patent license agreements and utility model license agreements and negotiate the terms for our clients.

Warning notice received due to patent infringement?

If you have received a warning notice due to the alleged infringement of a patent, a swift reaction will be required. Send us your warning notice by e-mail and we will review whether or not you committed an actual infringement of a patent. We will defend you against any unjustified claims. Maybe we are already familiar with your opponent.

Should you have received a warning notice from us, you might want to consult with colleagues who specialize in this particular field so we can resolve the matter without any effort and in due time.
