Successfully argued an appeal to the Russian patent office, facilitating protection of the client’s design in an important win for brand ownership and a rare victory against Rospatent, the state’s intellectual property office.
  • Spearheaded a strategy for a massive legal campaign on behalf of one of the world’s largest multi-business companies after a competing firm applied to use a similar corporate name. Led a highly successful strategic planning effort that covered 16 different countries, leading to a successful result and settling the case in multiple international jurisdictions.
  • Advised a renowned energy drink producer on a potential trademark conflict in Russia connected with a new product to be launched by a competing organization. Currently working on obtaining trademark status for the firm’s brand design.
