The office of patent attorneys Beer & Partner Patentanwälte KG can be traced back to the office of Privilege Attorney Zipser, which was originally established in the 19th century at the same location. The first patent attorney's office was established in these premises by patent attorney Theumer, continued by patent attorneys Viktor Beer and Otto Beer and later, by Manfred Beer as well. In 2000 the offices of Atzwanger and Beer were merged to form the present office of Beer & Partner Patentanwälte KG.
