About us

Our practice, founded in 2005 by Stefanie Augspurger and Gunther Friderichs, began as a law firm. In 2019, we as patent attorneys and attorneys-at-law specializing in engineering fields founded the practice known today as Augspurger Tesch Friderichs now located in Mainz.


What we do

Our focus is on your innovation in its specific market. We provide the personalized service you need, creating customized solutions for all of your intellectual property needs.

Once we have a firm grasp on your invention concept,we prepare and file the patent application, work diligently to advocate for you during the patent application examination process, and handle legal issues such as opposition and refusal proceedings or nullity suits.

We are here to advise you on license, research collaboration and co-development agreements. Our attorneys personally work on each step of your protection, defense, and enforcement proceedings.

We offer these services for all areas of industrial property rights, such as patents and utility model protection, as well as for trademarks and designs. 

Throughout this process, a thorough understanding of all aspects of your invention is paramount to us. Ideally, our technical and legal expertise will complement your expert team’s skills and abilities, perhaps adding a fresh perspective by viewing your technology from a different angle, and leading to new ideas. Our goal is to develop the best IP protection strategy with you; in one word – “intellectprotect”! 

For many years now, we have successfully represented our clients’ interests before the German Patent and Trademark Office (DPMA), the European Patent Office (EPO), the World Intellectual Property Organization (WIPO), the European Union Intellectual Property Office (EUIPO), as well as before courts of law in the Federal Republic of Germany and, since June 2023, also before the Unified Patent Court. A broad international network of experienced colleagues allows us to represent your legal interests globally.

Our location

The 42 line Gutenberg Bible is listed on the UNESCO’s “Memory of the World Register”. Johannes Gutenberg invented a printing press with reusable letters that remains relevant to this day for sharing all kinds of ideas. The movable types you see as the background illustration on our website were novel and useful, and symbolize what we help to get protected for you. We consider Mainz, home of the “Man of the Millennium”, to be the ideal site from which to manage all aspects of your intellectual property – the city in which Gutenberg introduced his significant invention located in the heart of the Rhine-Main area.

The Augspurger Tesch Friderichs Patent Attorneys and Attorneys-at-Law offices are  in downtown Mainz, within a 10 minute walk of the Mainz train station. Our offices are located in a historic building with a modern extension. On the top floor of this former French consulate, where traditional and contemporary architecture merge, we have both a platform and the strategic view to give you the best legal advice on protecting and developing your intellectual property.
