The Patent 1000 focuses exclusively on patent practice and has firmly established itself as the definitive 'go-to' resource for those seeking world-class legal patent expertise.

Recommended - Individuals: prosecution

An eminent name in IP practice, SBGK has been at the cutting edge of patent law development in Hungary for decades, by virtue of its client activities and extra-curricular engagement in policy and legislative initiatives and knowledge sharing. The ensemble can be relied on to take care of the most complex matters – contentious and non-contentious – and deploys wide-ranging technical expertise and sharpened legal and strategic skills to drive satisfying outcomes. Providing superb leadership are chemical engineer Zsolt Szentpéteri, who serves as managing partner of SBGK Patent Attorneys and as a member of the board of the same and SBG Attorneys at Law, and Katalin Szamosi, the president of the firm and managing partner of its lawyer branch. They have recently been working together on an important lawsuit in the pharmaceutical sector. Another top contact for contentious matters is Péter Lukácsi, whose abundant trial experience inspires confidence. The support of Ádám György is also a near guarantee of a good outcome in high-profile litigation; he has represented a patron before the European Court of Justice in a patent case, as has Lukácsi.For those interested in prosecution, a valuable senior-level contact includes Katalin Mészárosné Dónusz, who anchors the mechanical engineering practice. A key attribute of Mészárosné is her proficiency in handling international work for major Hungarian patrons.

Firm Profile

With more than 50 years of professional experience, SBGK Attorneys at Law and Patent Attorneys provides outstanding services in all commercial law areas, especially IP law, to domestic and international clients active in over 20 different industry sectors. Our lawyers and patent attorneys have decades of experience in all aspects of the defence and enforcement of IP rights. SBGK’s clients can rely on the expertise of our attorneys and patent attorneys in the area of legal proceedings required to secure IP rights and utilise the acquired rights. SBGK’s team of paralegals perform routine jobs associated with our clients’ IP rights quickly and with precision, under the supervision of our attorneys and patent attorneys. These tasks include IP rights portfolio management, patent annuities payment, preparing trademark searches and patent freedom-to-operate searches, as well as the completion of trademark, domain name and customs monitoring-related work. SBGK’s IP department is a well-known, reliable partner and an innovative, constantly available legal service provider that keeps abreast of law and practice developments.

SBGK’s attorneys at law are qualified to represent clients before the EU Intellectual Property Office (EUIPO), the EU General Court and the Court of Justice (ECJ).

SBGK has represented Unilever NV before the ECJ in the first-ever preliminary ruling referral to the ECJ from a Hungarian court in a trademark matter.
