Honors and Awards

    Any result the lawyer or law firm may have achieved on behalf of clients in other matters does not necessarily indicate similar results can be obtained for other clients.

    • 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.
