History of the Firm
In 1966, Ilse and Werner Freischem founded the intellectual property law firm “Patentanwälte Freischem” in the heart of the city of Cologne, Germany.
Stephan Freischem began to work in his parents’ firm in 1991. Three years later, after successfully passing the German patent bar exam, he became a full partner.
The team was further strengthened in August 2000 through the addition of Dr. Martin Tongbhoyai.
The team of “Patentanwälte Freischem” was extended by Thomas Buchenau in January 2007.
As of May 2010 Dr. Rolf Claessen has been taking care of our clients in the chemical and pharmaceutical industry.
Since 2015 the law firm is a limited liability partnership under the name of “FREISCHEM & PARTNER Patentanwaelte mbB“. This change was identity-preserving.
In the beginning of 2018, Hans-Martin Helwig joined the firm as partner.
