...The "excellent" Aleksey Zalesov, who fronts the patent practice, took command of these matters for both clients. "He is a very well-known name in this field, having held several respected public positions. He is also a highly skilled patent litigator and forms convincing arguments in court." His right hand is Irina Ozolina, another deft tactician and tenacious enforcer.
