We specialize in protecting intellectual property rights, which in a modern economy are essential for almost any business. Our team protects trademarks, patents, designs, copyrights, trade secrets and personal rights, we also help to protect against unfair competition practices.
SK+ Siekierzyński Kochlewski is proactively engaged in shaping clients' products and brands before they reach the market. We help prevent legal risks early in the design, naming and concept stages, and suggest the best possible means to develop and protect intellectual property. Hence, our advice is not limited to dispute resolution in litigation or ADR in the event of an infringement.

We focus on work for sectors like automotive, luxury goods, pharma, medical, art and marketing. The SK+ team has experience not only before the Polish courts but also before the Court of Justice of the European Union representing clients in complex and precedent-setting litigation.
Apart from representing clients in courts in civil litigation SK+ cooperates closely with Polish customs and police when it comes to fighting counterfeits. Many years of experience in representing clients in criminal intellectual property cases allow SK+ to manage proceedings appropriately by choosing the best solution for the case. The experience and ability to combine civil and criminal proceedings distinguishes SK+ from other Polish law firms dealing with intellectual property protection.
SK+ also provides comprehensive advice in the field of trademark prosecution and represents clients in all stages of the proceedings including: filing for registration, opposition proceedings, revocation and invalidity proceedings – before the Polish Patent Office and before the European Union Intellectual Property Office.

We protect international brands in Poland and Polish brands worldwide. We have experience in advising in complex patent infringement cases. We work with Polish and foreign patent and trademark attorneys and law firms, advertising agencies and consumer survey agencies. We also work with experts and specialists from various fields.

SK+ lawyers, including the partners, are very well versed in international relations. A good understanding with clients and lawyers from other jurisdictions is not only the result of language proficiency, but also stems from experience of living and working in a multicultural environment. These competencies have already resulted in important roles in international legal organisations for SK+ lawyers who are active in associations such as i.a. INTA, PTMG, Marques, German Association for the Protection of Intellectual Property (GRUR), AIPPI.

Due to the partners’ experience and background we are the first choice law firm for many multinational companies. We do not only speak fluent German and English, but we understand the mindset of our German and English/US clients. We also take on ‘difficult’ cases, one of the recent examples is the “Europe Impact Case of the Year” according to Managing IP. We represented our client Audi AG before the CJEU (case C-334/22).

In short, SK+ combines strategic foresight, hands-on litigation and deep academic insight in a highly specialized, boutique format.
