Welcome to the website of Patentbuero Paul Rosenich AG!

We are an international Patent law firm, our head office is domiciled in Liechtenstein. However, due to our branch offices and cooperation partners in Switzerland, Germany and Austria, we are also in a position to represent you and your clients before the national offices in those countries. Our main focus of our work is not only drafting and filing of intellectual property rights (in particular for Patents, Trademarks, Designs, Domain Names and Licenses), but also defending those rights before IP-Offices and courts. We also successfully file oppositions, complaints and actions for declaration of invalidity.

We are European Patent Agents and represent before the Swiss Patent Office (IGE), the Germany Patent- and Trademark Office (DPMA), the Trademark Office of Liechtenstein and the county court of Liechtenstein. We represent before World Intellectual Property Organization (WIPO), the Office for Harmonization in the Internal Market (OHIM), European Patent Office (EPO) and cooperate with Patent Attorney and attorneys worldwide. We also offer Mediation in the field of intellectual property in our branch office in Buchs SG.
