We focus on the drafting, filing and prosecution of patent applications (including opposition proceedings) before the European Patent Office, German Patent and Trademark Office and the Federal German Patent Court. In addition, we represent clients in IP-related litigation matters.

We cover the following technical fields:

  • electrical engineering
  • mechanical engineering
  • physics
  • information technology

We represent and advise our clients mainly with regard to:

  • patents
  • utility models
  • trademarks
  • designs
  • employee’s invention law


Our goal at HORN KLEIMANN WAITZHOFER is to offer our clients the best possible service, while keeping an eye on costs. Of particular importance to us is a close cooperation with our clients, since only a deep understanding of the technologies and needs of our clients allows us to offer sound advice in IP-related matters.

We offer:

  • a young dynamic team (immediate action also on short notice)
  • lots of experience in all procedures (DE, EP, PCT, designs, oppositions)
  • efficent internal processes
  • flexibility with respect to client’s processes and preferences
  • proactive prosecution with an eye on enforcement - thus increasing the value of our clients' portfolios (by considering our clients' technology, competitors' products, R&D, licensing)
