The patent and law firm GROSSE • SCHUMACHER • KNAUER • von HIRSCHHAUSEN, in short GSKH, is one of the very few German law firms in which patent attorneys and lawyers work jointly.

Therefore, our patent attorneys and lawyers are able to offer from only one source extensive and qualified legal advice and representation concerning all fields of intellectual property. Especially in infringement proceedings, it is necessary that patent attorneys and lawyers work together very closely due to the complexity of the matter. Consequently, in our law firm it is possible to guarantee a fast, efficient and continuous exchange of ideas between all patent attorneys and lawyers who are involved in a particular case.
