history of Hahn & Hahn
& Hahn was founded by Dr. W A Hahn who arrived in South Africa from
Europe during 1948 where he had previously been engaged for 20 years
in the multinational chemical industry as a patent expert. While qualifying
as a South African patent agent, Dr. Hahn was engaged in conducting
international license negotiations for the South African Coal, Oil and
Gas corporation Ltd. (SASOL) and setting up SASOL's patent and documentation
department, initially under his full time direction.
1951 Dr Hahn founded his own firm, Dr W.A. Hahn, at Pretoria where the
South African Patents and Trade Marks Office and Courts are situated.
For some years the firm continued to manage SASOL's patent department
on a part time basis. In building up the firm Dr. Hahn re-established
his past (mostly pre-war) contacts with industry and colleagues all
over the world.
completing his doctorate during 1957 in oil and coal chemistry and technology
at the University of Karlsruhe, Germany, Dr. H.H. Hahn joined the firm
as a full time assistant, qualifying as a patent agent in 1959. During
1961 he became a partner of the firm which was renamed Drs. W.A. Hahn
& H.H. Hahn. From these beginnings the firm grew steadily and continues
to do so.
Hahn was an international intellectual property adviser to several multinational
companies. His technical fields of experience include chemistry (including
pharmaceuticals, biotechnology, petrochemistry); chemical engineering;
conventional and alternative energy; natural and synthetic oils; bituminous
substances; wood and pulp technologies; mining, prospecting, and mineral
beneficiation; metallurgy; separation methods and apparatus; ecology;
energy saving and industrialised buildings.
was also a leader in the field of technical translations and is
fluent in English, German, Afrikaans and Dutch, while having a
reading knowledge of French.
the period in which Hans was active at Hahn & Hahn, Hahn & Hahn
expanded into a fully fledged Africa practice and files patent
and trade mark applications in ARIPO,OAPI, South Africa, Angola,
Nigeria, Egypt and other African countries.
September 1993 Hahn & Hahn merged with South Africa's largest
general law firm Webber Wentzel Bowens. During 1996, however,
a decision was taken to reconstitute the specialised intellectual
property law firm of Hahn & Hahn so as to enable it to independently
pursue those activities it knows best. These include the registration
and protection of intellectual and other property rights on behalf
of its national and international clients and associates and the
provision of expert and practical advice regarding intellectual
property, international trade and the environment.
