Maria Athanassiadou, Attorney-at-Law

Maria Athanassiadou is a partner and deputy managing partner at Dr. Helen G. Papaconstantinou and Partners ("HP&P"), one of Greece's foremost intellectual property law firms, and the recipient of the Patent Law Expert of the Year in Greece award at the 2024 Corporate INTL Global Awards. As an attorney-at-law within a practice devoted to intellectual property, she works at the heart of a firm whose reputation in patents, trademarks and related rights has been built over more than a century.

HP&P combines international expertise with a deep understanding of the Greek legal landscape, offering a full spectrum of intellectual property services. The firm's work spans patents, trademarks, utility models, industrial designs, supplementary protection certificates (SPCs), copyright, anti-counterfeiting, domain names, competition law, advertising and consumer protection, licensing and broader commercial matters, together with contentious intellectual property litigation. This breadth allows the firm to protect and enforce innovation across the full life cycle of an invention, from securing rights through to defending them.

As deputy managing partner, Athanassiadou holds a senior leadership role within the practice, contributing to its direction while advising clients on the protection of technical innovation. Patent law sits at the intersection of law, science and commerce, requiring a command of complex procedural rules and an appreciation of the technologies in question. The firm's patent practice supports domestic and international clients in obtaining and maintaining protection in Greece, and in navigating the interaction between national rights and the European patent system.

HP&P's international standing is reflected in its membership of the leading professional bodies in the intellectual property field, including EPI, ECTA, AIPPI, FICPI, INTA, PTMG and MARQUES. These affiliations connect the firm to the global networks through which cross-border intellectual property work is coordinated, an important asset for clients whose patent portfolios extend across multiple jurisdictions. The firm's quality management is underpinned by ISO 9001 certification, signalling a structured and consistent approach to client service across its practice areas.

The recognition of Maria Athanassiadou as Patent Law Expert of the Year in Greece reflects both her standing within HP&P and the firm's long-established prominence in intellectual property. Operating within a practice whose history stretches back over a hundred years, she is associated with a tradition of specialist expertise that has made HP&P a reference point for patent and trademark matters in Greece. The award from the 2024 Corporate INTL Global Awards affirms her contribution to a field in which technical rigour, procedural precision and international coordination are essential, and highlights the continuing strength of Greek intellectual property practice on the international stage.
