Overview

Jeanne (“Jeannie”) Heffernan is an experienced trial lawyer focusing on patent and trademark infringement litigation. Jeannie has won more than a dozen patent and trademark infringement cases around the country in a wide range of industries, from medical devices to telecommunications to haute couture.

Jeannie's work was mentioned in the following articles:

  • She “knows how best to conduct patent trials in the Eastern District of Texas, no matter what the technology involved. She litigates across the country and recently represented Medtronic in the Southern District of Florida, where she artfully obtained a summary judgment of non-infringement against patent assertion entity Atlas IP.” – IAM Patent 1000, 6/2016

  • She is described as having as “much experience in the Eastern District of Texas as any national litigator and has managed to get some big wins on the defense side there in terms of arguing for the exclusion of the plaintiff’s damages expert. She’s great at interrogating experts and witnesses, and her follow-up questions are especially probing.” – IAM Patent 1000, 6/2015
