In business for over
100 years

Our office is in business since the end of the 19th century. Johannes Rieder, the grandfather of the firm’s current senior partner, was a licensed adviser for inventors in Wuppertal-Elberfeld even before the Patent Agent Attorneys Act came into force in 1900. After the Second World War, the firm moved to Wuppertal-Vohwinkel, where Dr. Hans Rieder ran the firm for a number of years on his own. He was succeeded by Dr. Hans-Joachim Rieder. In 1987, the foundations were laid for the firm we know today, Dr. Rieder being joined initially by Patentanwalt (Patent Attorney) Enno Müller and Rechtsanwältin (Lawyer) Dr. Ursula Schwendemann (until 2002), and then in 1993 by Patentanwalt (Patent Attorney) Dr. Dirk Grundmann. In 2002, the team was strengthened further when Patentanwalt (Patent Attorney) Dr. Helmut Brötz and Rechtsanwalt (Lawyer) Hendrik Bourree joined the office. The office was further strengthened 2009 bei Michaela Bartz (Lawyer) and in 2014 bei Dr. Marion Horn (European Patent Attorney).
