Barger, Piso & Partner


The office of Patent Attorneys Barger Piso & Partner has a tradition and experience of more than 100 years.

At the beginning of the 20th century Mr Urbantschitsch opened a patent law firm which was ultimately continued by his grandson, Eberhard Piso, in 1966.

In 1925 Mr Mayer, a former employee of Mr Urbantschitsch, started his own patent law firm, joined by Erich Barger in 1948 who continued it with a partner, Hermann Krick. In 1981 Erich Barger's son Werner Barger joined the firm.

In 1992 the two above-mentioned patent law firms merged under the name of Barger Piso & Partner.

At the beginning of the 20th century Mr Hamburger founded a patent law firm which was continued by his son Walter Hamburger and his grandson Walter Alfred Hamburger. Peter Israiloff joined that law firm in 1969 and continued it after  Walter A Hamburger's death.

As of 1 December 1997 the patent attorneys Barger Piso & Partner took over the Hamburger patent law firm and moved to the latter's offices. Peter Israiloff joined the firm as a partner. In 1999 the senior partner Hermann Krick, in 2003 the senior partner Erich Barger died.
