Benjamin Quest has extensive knowledge and experience in various biotechnology and patent law areas. His expertise covers the entire range of biotechnological fields, particularly the drafting, prosecution and grant of patent applications before the European Patent Office. He is equally adept at conducting EP opposition proceedings and drafting and handling third-party observations. He also advises clients in foreign grant proceedings through cooperation with our numerous international representatives.

His work further focuses on the sequence analysis of biological sequences and their standard-compliant integration into patent applications. In addition, he has extensive experience in conducting freedom-to-operate (FTO) analyses that identify potential legal risks.

Benjamin provides comprehensive support and advice to a diverse client base. His clientele ranges from individual inventors and medium-sized companies to educational institutions and renowned pharmaceutical companies.

He is a sought-after expert in European regulations and case law on supplementary protection certificates (SPCs). His experience ranges from registering such certificates in Germany to comprehensive support at the European level. He is also well-versed in applying for pediatric renewals of these SPCs.

Benjamin is a member of EPI (member of the EPI Biotechnology Committee since 2023). During his studies, he received the following scholarships: Chemical Industry Fund (doctorate), Max Planck Scholarship (postdoc).

And even at minus 15 degrees, Mr. Quest still rides his bike.
