History

HP&P started as a solo practice, founded by Dr. Panagiotis Theodorides in 1920 and is one of the oldest Trademark and Patent Law Firms in Greece.

The firm specialised from the very beginning in all aspects of Intellectual Property Law, primarily Patents, Trademarks, Industrial Designs, Copyright, Domain Names, Unfair Competition, Licensing and all related litigation.

Over the past 90 years, the Firm has grown steadily to become the largest Firm in Greece to specialise exclusively in IP.

Dr. Helen Papaconstantinou joined the firm in 1965, became a full partner in 1971, and has been heading the firm since 1986.

In order to better serve its clients and maintain a competitive practice covering the broad spectrum of Intellectual Property Law, the firm evolved into two distinct branches in 1996, the one under the old firm name LAW OFFICE DR. P.D. THEODORIDES – DR. H.G. PAPACONSTANTINOU covering Trademarks, Domain Names, Copyright, Customs Monitoring Procedures and all Intellectual Property related litigation and the other under the name DR. HELEN G. PAPACONSTANTINOU, JOHN V. FILIAS AND ASSOCIATES, Business Consultants, S.A. covering Patents, Industrial Designs, Utility Models and all related activities and consulting.

Over the years, the firm extended its services to cover Supplementary Protection Certificates, Plant Breeders’ rights, Anti-Counterfeiting and Antipiracy law, New Media and Technology Law, Franchising, Commercial and Corporate Services, Internet, E-Commerce and Domain Names.

In 2015, 95th anniversary of the firm, Dr. Helen G. Papaconstantinou opened a new page in its history, announcing the founding of the Law Firm Dr. Helen G. Papaconstantinou and Partners (HP&P), which evolved from the two aforementioned branches, moving forward with all the existing staff, who bring with them their expertise, experience and knowledge.

The Managing Partner of HP&P is Dr. Helen G. Papaconstantinou and the other four partners are: Eva Yazitzoglou, Miranta Theodoridou, Maria Athanassiadou and Fotini Kardiopoulis.

This move, adjusting the practice to the modern standards of the legal profession, aims at increasing the depth and breadth of services to our international superb client base and to fully secure the needs of our clients with portfolios of various IP rights.

We are committed to continue working hard to deliver high quality tailored expert services in the IP sector and look forward to exploring opportunities to provide you with additional value in new areas.
