Our firm looks back on more than 150 years experience; it has the longest tradition an Austrian IP firm could possibly have.


It can be traced back to times before the establishment of what may be called the first modern law for protection of inventions in Austria, the "Privilegiengesetz" of 1852, as it is on the basis of which professional representation in patent matters was officially started.

At that time, usually inventors, who themselves had successfully taken the steps needed to obtain own "technical privileges" i.e. patents, on their own inventions, were in charge of handling patent cases for others. For instance, the ancestors of our office came from the machinery and textile field, the high-tech area of these days.

Frederick Paget, brother of Sir James Paget, personal physician of Queen Victoria (and discoverer of "Paget's disease", a rare type of breast cancer), was the founder of the first office of patent representations ("Erstes Privilegienbureau") in Austria in 1851. Right from the very beginning, he established his office in the centre of Vienna, in Riemergasse, where our office today still is. Soon thereafter, he was joined by his son, Charles Octavius Paget, and by Julius Moeller. Among their early clients were such luminaries as Thomas A. Edison, Henry Bessemer and George M. Pullmann, all of whom entrusted our office to file for grant of their technical privileges.
