Patents & Publications

Can there be a better reference than a patent ?

Can we possibly receive a greater award for our excellent speech than the one we were given by a professional audience on the occasion of a conference ?

Our innovation power and our constant drive for further development results in numerous patentable solutions – thus we increase the competitiveness of our customers.
