About

Rolf is partner of IP boutique law firm Freischem. The firm is managing about 4500 trademarks and 6500 patents and patent applications for mostly domestic medium sized clients in Germany.

His personal background is chemistry and nanotechnology. Before becoming a patent attorney, he received his Ph.D. from the College of Nanoscale Science and Engineering as well as the Chemistry Department, both at the State University of New York at Albany. Also, he worked for a small nanotechnology startup that was spun out of the Bayer group.

The focus of his practice is the prosecution of trademarks and patents. With the team at Freischem, he strives to be the external IP department for many medium sized companies.

Rolf has been included in the Patent 1000 rankings of the IAM magazine in 2013 and 2014. And he received confirmation that he also will be included in the WTR1000 ranking in 2015.

He is a prolific writer mostly writing for law journals such as GRUR or IP Rechtsberater. He is host of his two podcasts Markenpod and IP Fridays.

Rolf is also volunteering his time in the worldwide volunteer organization Junior Chamber International (JCI), where he currently serves as executive congress director for the JCI World Congress 2014 in Germany.

He enjoys spending at least the weekends with his three kids and his wife. Rolf wishes to have more time for hobbies like sailing.
