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.

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, Dr. Hans-Martin Helwig joined the law firm as partner.
