About service

We develop comprehensive patent strategies aimed at increasing monetization of the patented technologies and/or allowing the client’s businesses maximum freedom of operation.


Patent law is one of the most essential areas of intellectual property law – and one of the most complicated ones. A patent, once granted, ensures its holder’s exclusive right to use or license a respective invention, utility model or industrial design – and to take action against those using it illegally.


Obtaining patent protection and benefitting therefrom requires profound expertise and attention to minor details. It starts with patentability advice followed by successful patent prosecution in Ukraine and/or abroad. Once patent is obtained, it can be assigned or licensed to a third party. Sometimes an SPC may be received to secure an extended term of patent protection.


Even if a patent is granted, it will be cheap without its effective enforcement. A dispute may be resolved either amicably (via cease-and-desist letters, negotiations, etc.), or through litigation and/or customs and/or law enforcement agencies. Alternatively, our client may wish to ensure that its business is not hindered by the opponent abusing its patent rights - sometimes the patent protection may be bypassed by taking advantage of loopholes in the claims. The client may also wish to take it one step further and challenge the validity of the opponent’s patent. Any patent case brought to the court will likely require cooperation with forensic experts.

Our team has extensive experience both in patent prosecution and patent litigation. We understand the client’s needs and develop comprehensive patent strategies – be it by enforcing the patents, bypassing or challenging it. We develop and implement patent portfolio management strategies and patent litigation and enforcement strategies in disputes spanning across multiple jurisdictions, achieving synergy of legal and technical skills.
