Our firm in Horb was founded by Elmar Ott in 1981. Since then, it serves national and international clients. In 1993, Peter Klocke joined, and in 1995 Dieter Späth. After the departure of Mr. Ott in 1996, the firm of Klocke and Späth continued. In 2002, we associated with Carl Otto Barth of Barth & Partner in Adliswil/Zürich, Switzerland, and now provide, as ABACUS Patentanwälte in Nagold and Zurich, a comprehensive range of services for our clients in Germany, Switzerland and elsewhere. In 2013 we merged with Ott & Sebastian, having offices in Rottenburg and Heiligenhaus. With the joining of Patent Attorney Jens Sebastian we moved with the office from Horb to Nagold. Since Oktober 2018 Patent Attorney Jens Sebastian manages his office in Heiligenhaus in own reponsibility with a cooperation betwenn the two offices.
