    • Serving as first chair, Barry represented DynaEnergetics in a patent and trademark suit brought by GEODynamics in the Eastern District of Texas. After a four-day jury trial, DynaEnergetics obtained a complete defense verdict, including a finding of noninfringement and three different bases of invalidity for each of the patent claims. At a subsequent bench trial on the trademark “reactive,” Judge Payne issued a judgment canceling GEODynamics’ incontestable trademark, finding that it was generic. Barry also represents DynaEnergetics in two inter partes review proceedings at the USPTO.
    • Barry served as first-chair litigator in a landmark patent infringement case for client Saint-Gobain, one of the world’s largest glass companies and the leading windshield manufacturer for European cars. Saint-Gobain won a $10.9 million damages award against a Chinese windshield manufacturer, and the jury found the infringement was wilful. The district court subsequently doubled the damages award and granted Saint- Gobain attorneys’ fees and costs for a total award exceeding $24 million.
