I currently work on an analysis of the proportionality requirement in patent law; the meaning and scope of Article 17(2) Charter of Fundamental Rights; the place of economic analysis in patent litigation; and workable guidance for open standards in private law, as well as various side-projects, for instance on descriptive trade marks. If you’re interested in these topics as well and looking for a sparring partner, don’t hesitate to get in touch.

You can download selected publications by visiting my author’s page on SSRN.
