Dr. Rolf Claessen   Premium-Mitglied   Gruppenmoderator

In erster Linie bin ich Patentanwalt / Patent Attorney und Markenanwalt. Ich arbeite Schutzrechtsanmeldungen aus (Patentanmeldung, Markenanmeldung, Gebrauchsmusteranmeldung, Geschmacksmusteranmeldung) und setze die resultierenden Schutzrechte (Patent, Marke, Gebrauchsmuster, Geschmacksmuster) durch. Vor allem interessieren mich die Gebiete Nanotechnologie, Oberflächenanalytik (RBS, AES, XPS, SEM, AFM, linearer Teilchenbeschleuniger, Rasterelektronenmikroskop), Oberflächentechnik, Werkstoffe, Materialwissenschaften, Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), Halbleiterfertigungsprozesse. Folgend einige Projekte und Veröffentlichungen, die auf mich zurückgehen:
