SBGK Attorneys at Law and Patent Attorneys is “one of the largest local players that operates at the pinnacle of IP in Hungary”. During its more than 50 years in operation it has built up a diverse base of domestic and international businesses, acting on their behalf before Hungarian, European and international authorities. Managing partner Katalin Szamosi “is a brilliant expert and one of the most experienced practitioners in Hungary. She is a very tough opponent who refuses to give up.” Szamosi often works closely with Máté Borbás on major mandates for patrons such as Red Bull GmbH and Spin Master Toys UK, the owner of the Rubik’s Cube brand. The firm also represents world-famous Hungarian fashion brand Nanushka International Zrt. Ádám György is instrumental in the global portfolio management work for this client, which includes the filing of new marks in the European Union and across the globe. Another top performer on the team is Péter Lukácsi who “has very deep knowledge of trademarks, vast experience and a great reputation on the market”. A familiar face before the Hungarian Intellectual Property Office (HIPO), EUIPO, EPO and WIPO, Gabriella Sasvári excels in portfolio management and enforcement proceedings. As Sasvári enters the latter stages of her illustrious career, she will be passing the torch to WTR 1000 debutant Adrienn Sályi, a third-generation lawyer at the ensemble, whose forte lies in trademark prosecution.
