Tobias Ehnis was born in Karlsruhe, Germany in 1965. After completing his studies in biochemistry at the
Free University of Berlin, he worked as a scientific collaborator at the University Hospital Benjamin Franklin, Berlin. His research centered on cell biology, analysis of receptor-ligand-interactions as well as purification and characterization of receptors and their ligands.
After obtaining his PhD in 1996, Dr. Ehnis accepted a position as scientist at the medical department of the Friedrich-Alexander-University Erlangen-Nuremberg. His research work concentrated on the areas of molecular biology, immunology and apoptosis. Ehnis published his results in numerous scientific journals. He is also the inventor of an immunological detection assay.
Since 1998 Ehnis has been working in the field of intellectual property. In 1999 he joined the patent law firm Dr.-Ing. Wolfgang Gassner and in 2001 passed the patent bar exam. In 2002 he became a partner of the patent law firm Dr. Gassner & Partner.
Ehnis is German Patent Attorney and European Patent Attorney. He is also registered to practice before the Office for Harmonization in the Internal Market of the European Community in Alicante, Spain (European Trade Mark Office). The main areas of his work are the drafting, filing and prosecution of patent applications in the fields of biochemistry, molecular biology, genetic engineering, diagnostics, pharmaceutics, medicine, chemistry and organic chemistry.
