Testimonials
Collated independently by Legal 500 research team.
- This is a team of lawyers who work seamlessly hand-in-hand. In any given project, if special expertise is needed, nozero time Oppenheim will add a specialist to the team. As soon as that particular skill is no longer needed, the specialist steps back. This works seamlessly, and it is very efficient.’
- ‘Áron László is the leading lawyer I am in touch with. Once he is on a case, he represents the client with 100%. And he would go to any length to help me and to support me. If needed, he would advise me to involve other specialists. I regard him as an individual with outstanding intellect, dedication, and firm moral standing.’
- 'They demonstrated a high level of professional expertise, showed a clear understanding of the legal framework governing patent-related preliminary injunctions, thoroughly analysed the client’s situation, and ultimately provided well-founded recommendations.'
- 'Based on the recommendations provided, the client implemented appropriate preventive measures, and ultimately, its sales activities proceeded safely without any injunction issues. We also continue to cooperate with Áron László in other trade mark issues.’
- 'The IP team led by Áron László made a particularly strong impression, and we ultimately decided to work with them. Their key strengths lie in their ability to quickly and accurately understand the client’s needs, their thorough familiarity with the legal framework surrounding the client’s concerns, and the fact that their recommendations were solidly grounded in both legal reasoning and practical experience.’
- ‘An accurate, precise, and reliable team. They are solution-oriented, always keeping the client’s interests and the legal framework fully in mind. Working with them is easy—in the best sense of the word. They provide clear and concise answers, exactly what a busy client needs. They also keep track of the entire legal process, and whenever there is a change in status, they send a clear, easy-to-understand summary.’
