Your property rights in good hands: our services

You continue innovating—and let us take care of all the legal matters! For example, we’ll support you with the development, registration, and pursuit of your property rights. Moreover, we’ll advise you strategically on the systematic set-up, management, and maintenance of a patent portfolio, the design of intellectual property rights management for your operation, and due-diligence processes.

We’ll represent you in all matters relating to industrial property rights and associated areas of law before courts and authorities. This includes defending and enforcing your intellectual property rights.

Is your innovation at all patentable? Are there any intellectual property rights that stand in the way of your development? And are your existing property rights actually legally valid? We will also support you when it comes to such issues, for example through research, assessments and freedom-to-operate analyses. And we will check whether your intellectual property rights possibly collide with third-party rights or might even be infringed by third parties. Moreover, we will prepare reports on whether your property rights might possibly also affect essential technologies, without which other companies would have no access to the market.

If you reach special R&D, demarcation or licensing agreements with competitors, we will support you with the relevant contractual issues. And should these or other issues lead to a dispute with the other party, you can also count on us. We’ll advise and represent you – in alternative dispute settlement procedures (e.g. in arbitration courts) too.

Profitable growth through innovation: our IP consulting

Significantly more potential than you think lies in patents, utility models, trademarks, and designs. As long as these IP rights specifically protect what makes your business profitable and what your customers are willing to pay a higher price for, your IP portfolio is more valuable than before.

We always take a holistic approach and will support you in successfully positioning yourself and your intellectual property rights in the market as an innovative company.
