Firm Profile

Dr. Helen G. Papaconstantinou and Partners (HP&P), with a history that spans over a century, is broadly recognised as a leader in the IP law sector in the country.

HP&P enjoys an international reputation for high quality expert services. It provides sophisticated legal and business solutions in the full IP lifecycle, from advising on and prosecuting IP portfolios; assessing, managing and maximising the value of intellectual property in commercial and licensing transactions through out of court negotiations and settlement; IP litigation; and enforcement strategies. The firm aptly combines its international orientation with a thorough knowledge of the Greek legal and business environment. What sets HP&P apart is its extensive experience and expertise in the entire spectrum of IP services and its commitment to problem solving and achieving results. HP&P was the first law firm of its kind to implement ISO 9001/2015, a quality control system.

The four partners of the firm are Eva Yazitzoglou (Managing Partner), Miranda Theodoridou, Maria Athanassiadou and Fotini Kardiopoulis.

HP&P is home to 12 fully qualified lawyers with considerable experience in all IP matters gained over many years of practice. Two ΗP&P attorneys are European patent attorneys; one is trained and certified by the European Union Intellectual Property Office; and all of the firm's attorneys are members of the Athens Bar Association. Most of them are admitted to practise before the Supreme Court and the Council of State. HP&P also enjoys the valuable assistance of a highly specialised and qualified academic as of counsel to the firm; they are also assisted by a knowledgeable and experienced legal consultant. In addition, with the efficient assistance of 21 experienced paralegals and supporting staff, HP&P provides legal and administrative services of excellent quality and closely collaborates with 40 technical counsellors whose expertise covers all technical fields. These technical counsellors have accredited degrees (the majority including post-graduate studies) in sciences, (eg, physics, chemistry or biochemistry, biology and electrical, electronic, chemical and mechanical engineering) and most of them are or have been involved in academic research. They are all competent translators for English, French and German and regularly provide consulting services of the highest quality, based on their technical expertise in patent matters.

The firm serves its foreign clients in Greek, English, French, German, Spanish and Italian.

HP&P is registered in the Athens Bar Association and is a member of the Greek Association of Law Firms.
