Our practice is one of the largest and oldest in the intellectual property sector in Greece. The firm was founded in 1920 by Dr Panagiotis D Theodorides. Dr Helen G. Papaconstantinou became a partner in the 1970s and has headed the firm, as his successor, since 1986.
In 1996, in order to better serve its clients the firm evolved into two branches: Dr PD Theodorides–Dr. HG Papaconstantinou, Law Offices; and Dr Helen Papaconstantinou, John Filias and Associates SA. These operate in parallel and in close cooperation with each other.
Our staff includes 14 highly specialised IP attorneys, three of which are European patent attorneys (grandfathers) and we collaborate with a team of 30 qualified technical counsellors–patent translators.
Both branches have been certified as per the ISO 9001:2008 Standard.
