Espatent is smaller than its leading competitors but has niche specialisations on top of the traditional patent areas that distinguish it in the market. The firm has exceptional expertise in telecommunications, paper machinery and mining technology, with European patent attorneys Samu Lamberg, Sampsa Söderholm and Sanna Kalliola, and Finnish patent attorney Ilkka Väänänen. In 2010, the firm also brought Finnish patent attorney Kari Lång into the fold to deepen expertise in telecommunications, electronics and software. The firm also provides independent experts for patent dispute cases in court.
