For many years our office is ranked as one of the leading Austrian firms for Intellectual Property and for the Law against Unfair Competition:


“Die IP-Boutique gehört mit ihrer ungebrochenen Prozesspräsenz zu den führenden Kanzleien im Marken-, Wettbewerbs- und Patentrecht.”


“Wiltschek Rechtsanwälte covers the whole range of IP work, from patents and unfair competition to trade marks and copyright while clients also benefit from the firm’s knowledge of EU-wide legislation.”


“Wiltschek is a small niche firm that specialises in contentious IP work. The firm punches above its weight and is widely respected by opponents. One rival says the firm is ‘one of the best in the field’, with ‘IP guru’ and name partner Lothar Wiltschek at the helm. He is supported by IP star David Plasser and both ensure clients receive the highest level of advice.”
