Hungary SBGK Attorneys at Law and Patent Attorneys

In 1969 three renowned patent attorneys and a number of attorneys at law established the Patent and Law Office for International Affairs, the legal predecessor of SBGK Attorneys at Law and Patent Attorneys. SBGK was the first private firm to combine the knowledge of attorneys at law and patent attorneys. For almost half a century, SBGK has held its market-leading position of providing quality service in IP law.


SBGK’s attorneys at law and patent attorneys attend international seminars and conferences every year to stay ahead of the competition. They are frequently invited to speak as guest lecturers at Hungarian and international events, the results of which are numerous publications in international professional journals and bulletins. SBGK also organises conferences, roundtable discussions and international symposia in Hungary. SBGK’s attorneys at law are qualified to represent clients before the EU Intellectual Property Office (EUIPO), the EU General Court and the European Court of Justice (ECJ). For example, it represented clients in the first preliminary ruling referral to the ECJ in a Hungarian trademark matter. Similarly, SBGK’s patent attorneys are all registered as European patent attorneys and can represent clients before the European Patent Office (EPO) and the EUIPO.


The cooperation of patent attorneys and attorneys at law allows SBGK to represent clients in complex IP law matters. SBGK offers services in:

  • patent, industrial design and trademark prosecution matters before the Hungarian Intellectual Property Office, the EPO and the EUIPO;
  • IP rights enforcement (civil litigation, oppositions and domain name disputes);
  • contracts for international licensing, franchising and technology transfer matters;
  • IP portfolio management; and
  • annuities fee payment, trademark screening, freedom-to-operate searches and anti-piracy campaigns.

In addition to SBGK’s strong IP practice, it helps foreign investors to set up their business in Europe and provides them with all necessary legal services in company establishment, mergers and acquisitions, employment law matters and various other commercial transactions.


SBGK, as the leading IP law firm in Hungary, offers not only professional services, but also a broad network of international contacts, which includes well-known national and international firms of attorneys at law and patent attorneys, guaranteeing high-quality services. SBGK’s attorneys at law and patent attorneys are members of and hold various positions in international IP organisations such as the International Association for the Protection of Intellectual Property, the International Trademark Association, the International Federation of Intellectual Property Attorneys, the European Communities Trademark Association, MARQUES, UNION, the Pharmaceutical Trademarks Group, the Licensing Executives Society International and the Institute of Professional Representatives before the European Patent Office.
