Patent Attorneys

Peter Hess’s main areas of practice involve patent infringement in a number of technical fields (particularly semiconductor technology, telecommunication technology, optoelectronic systems and computer-related inventions), license agreements, complex patent prosecution cases, and opposition and patent nullity proceedings at all instances before the European Patent Office and the German Patent and Trademark Office.
Peter Hess was recently part of a Bardehle Pagenberg team of patent attorneys and attorneys-at-law successfully defending a global DRAM manufacturer of semiconductor memory chips in a series of cases.
He has also handled important cases concerning hardware emulation systems for the verification of integrated circuits and diagnostic sensors for medical applications, as well as various infringement cases in the automotive supplier industry. Many of his cases involve managing parallel patent litigation across various European jurisdictions, with most of these requiring careful coordination with parallel litigation in the US.
