Trade mark

Case studies demonstrate that the firm represented Avia International in a trademark infringement lawsuit before the Supreme Court of Cassation in opposition, filed on behalf of the client against the registration of a Bulgarian national trademark, applied for by the other party, which conflicts with the client’s earlier EUTM.  Sofia Lefterova is the key practitioner to watch. 

Patent

Case studies show that the firm advised Mylan Ireland Limited on Bayer Healthcare's claim against Mylan Ireland Limited and Mylan EOOD, collectively referred to as Mylan regarding the alleged unlawful use of the medicinal product Sorafenib in Bulgaria. 

Copyright & related rights

Case studies show that the firm acted as local counsel for UK-based educational software and services provider Juniper Education Holdings Limited backed by UK investor Horizon Capital about the legal due diligence and acquisition of Shkolo EOOD. This company has created and maintains the largest Bulgarian administrative and management software platform for schools.
