We are litigation experts who manage the patent life cycle, ensuring patents are litigation-ready.

Practice Areas

We regularly handle IP litigation cases, including patent infringement, nullity and entitlement actions, in all of our technical fields. We align our strategy with your business objectives and build the ideal team for your specific matter. If desired, we select attorneys at law from our established network of top-notch firms. We represent our clients in complex cases before the Federal Patent Court, the European Patent Office, the German Patent and Trademark Office and the Unified Patent Court. Our expertise is reflected in multiple landmark IP decisions handed down by the German Federal Court of Justice. Your value: Maximum chances of success.
We have far above average experience and knowledge in opposition and appeal proceedings before the German Patent and Trademark Office, the European Patent Office and the Federal Patent Court. We know the respective Rules of Procedure and the relevant case law by heart. We provide you with realistic assessments on the strength of a case. We cultivate contacts with Judges and Examiners. We fight for you. Your value: Powerful attacks on the rights of your competitor; steadfast defenses of your own IP.
We take the time to carve out the core of each invention through in-depth discussions with the inventors. We translate this core into an application, taking into account the peculiarities of German, European, and international patent law. We care about details. We prosecute your applications efficiently and get results, as we know the relevant procedural law by heart and seek dialogue with the examiners. At the same time, in drafting, prosecuting and maintaining your patents, we address all important aspects that could arise in potential post-grant litigation. Your value: High-quality IP rights.
Developing new products and bringing them to market always requires careful evaluation of competitors’ IP. We help you guide development, clarify technical areas and support internal decisions to avoid legal deficiencies. We work at the interface between legal and technical teams to make recommendations to management and guide internal decisions. We assist market leaders in navigating the competitive IP environment from the conceptual stage to the product marketing phase. Your value: Legal certainty for your successful products.
Your IP strategy needs to be aligned with your company’s goals. This involves implementing an innovative culture and ensuring that your products, your markets and your IP are properly aligned, all while keeping an eye on your competitors. We have helped several multi-national corporations reduce their IP costs by identifying potential for optimization while still maintaining the benefits of their IP portfolios. Your value: Optimal alignment between your IP and your company goals.
Mergers and acquisitions regularly involve evaluating the strengths and weaknesses of IP portfolios, often in a matter of days. Whether you’re on the seller side or the buyer side, we ensure that no “red flags” are missed. This involves assessing the portfolio’s alignment with the company’s product, potential legal defects in the portfolio and the portfolio’s value to the buyer. We make sure you find the right answers to any questions that may arise during the transaction, and take over responsibility for the legal assessment and the short turnaround times involved in the process. Your value: Legal security in IP transactions.
