The TETRAPAT patent and trademark office was founded in 1990 by RNDr. Zdeněk Halaxová according to the then recent law on patent attorneys. First in Olomouc, since 2003 also in Prague. Since then, we have become a family business, where five members of our family work so far. All our people have many years of experience, appropriate education, technical, scientific and legal education. We are based in Prague 5 in Jinonická and in Olomouc in Ztracená. In the vast majority of cases, we work for our clients for a long time.
