She serves as the chairwoman-elect of the "chemistry and the law" division of the American Chemical Society (ACS) and has spoken around the world regarding intellectual property.

Q: What is the most challenging case you have worked on and what made it challenging?

A: The most challenging case that I have worked on over the past several years has been an inter partes reexamination. It was one of the earliest inter partes reexaminations filed, so it was challenging to make sure we were doing everything correctly from a procedural standpoint and to make sure we put our best case forward.
