Patent Attorneys

Patent infringement in a number of technical fields, in particular semiconductor technology, telecommunication technology, optoelectronic systems and computer-related inventions; license agreements; complex patent prosecution cases and opposition and patent nullity in all instances before the European Patent Office and the German Patent and Trademark Office.

Recently, Peter Hess was part of a Bardehle Pagenberg team of patent attorneys and attorneys-at-law who successfully defended a global DRAM manufacturer of semiconductor memory chips in a series of cases.

Further important matters have concerned hardware emulation systems for the verification of integrated circuits, diagnostic sensors for medical applications and various infringement cases in the automotive supplier industry. A common characteristic of many cases is the management of parallel patent litigation across different European jurisdictions. Most of these matters require careful coordination with parallel litigation in the US.
