Attorney Bio

"To determine whether you are using someone else’s patent, you have to be able to take the technology at issue, whatever it is, and relate it to what the patent actually says. My job is to take very complex technology and make it totally accessible, so that the judge and jury see exactly how it works and what it does. When I present my client's case to a jury, that's all I do. I love seeing the figurative lightbulb above their head."

—Todd Landis
