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, Austria, Hungary, Portugal and USA we are also in a position to represent you and your clients before the national offices in those countries and/or can meet with you directly in the mentioned countries. The main focus of our work is not only drafting and filing of intellectual property rights (in particular 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. Of course we also successfully defend in such actions mentioned before.
Our international team of internal and external associates covers European Patent Attorneys and representatives before the Swiss Patent Office (IGE), the Germany Patent- and Trademark Office (DPMA), the Hungarian Patent Office, the US Patent Office, the Trademark Office of Liechtenstein and the County Court of Liechtenstein. We represent also before the World Intellectual Property Organization (WIPO), the Office for Harmonization in the Internal Market (OHIM), European Patent Office (EPO) and cooperate with Patent Attorneys and Attorneys at Law worldwide. We also offer Mediation in the field of intellectual property in our branch office in Buchs SG/Switzerland.
