Groundbreaking Graphics Team

Establishing and protecting the value of today’s most advanced, complex technologies often requires communicating sophisticated and subtle technical ideas to judges, juries, government agencies and investors, many of whom have limited technical backgrounds. To achieve optimal communication, we rely on the skills of our attorneys, supported by an award-winning in-house graphics and animation team. Our graphics professionals create state-of-the-art 2D and 3D static and animated visual media to ensure that the Ropes & Gray team can communicate with the most advanced technical experts and convey information in a clear and persuasive manner to judges and juries alike.
