A springboard and driver of innovation

We offer a full service – that has been our aspiration from the very beginning. Because we know that many great ideas are left unsaid or hidden in desk drawers, and only come to light when it’s too late. Or they get into the wrong hands. That’s why we smooth the way, dig deeper, and follow things through to the end. Because we are not just patent and trademark attorneys, we are also enthusiastic about technology. We recognize early on what path an innovative spirit will take.

Promoting pioneering spirit and supporting innovation

Changing times are often a driving force for new ideas, as recent events have shown. We embrace innovation and thrive on state-of-the art technologies. Because we are as passionate about excellence as our clients are. Renewable energy and energy technology, fuel cell and hydrogen cell technology, e-mobility and charging stations, robotics, optics, image processing and imaging technology, digital and mobile communication, data transmission systems, sensor technology or solid state physics – these are just some of the topics we deal with in our work.

From the code of law to a vision

Protecting your innovation is our main concern. We want your idea to survive, and for your company to take the leap into the future. Creativity and commitment are motivations we share. That also includes systematically registering patents: A patent strategy and a sustainable portfolio will help you to position yourself successfully against the competition. Our partners support you with their expertise and with empathy, and are driven by the same constant thirst to discover and understand new things.
