Representative Experience

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.

  • Secured a favorable defense verdict after a jury trial before Judge Albright in the Western District of Texas. In 2021, Repeat Precision, a competitor in the oil and gas industry, filed a lawsuit against DynaEnergetics, alleging that one of DynaEnergetics’ products (a setting tool used in downhole perforating) infringed on one of its patents. Repeat Precision sought damages and an injunction to halt DynaEnergetics’ production and sale of the setting tool. On April 3, 2023, the jury concluded that DynaEnergetics did not infringe any asserted patent claims.  
  • Serving as first chair, Barry represented DynaEnergetics in three intellectual property litigations brought by GEODynamics in the Eastern District of Texas:
    • After a four-day jury trial involving a method patent, in March 2017, 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 led a team at the PTAB that successfully invalidated all asserted claims of a product patent in an inter partes review proceeding.  The final decision was issued in March 2018.
    • After a four-day jury trial in October 2018, DynaEnergetics obtained a complete defense verdict of a product patent, including a finding of noninfringement and invalidity of each of the patent claims.
  • In only the fourth case that the Precedential Opinion Panel (“POP”) at the USPTO, consisting of Director Iancu, Commissioner Hirshfeld, and Chief APJ Boalick, has ever reviewed, and the first related to a Final Written Decision, Barry successfully urged the POP to rule in his client’s favor in Hunting Titan, Inc. v. DynaEnergetics Europe GmbH.  The POP granted DynaEnergetics’ request for rehearing and its motion to amend in a closely watched decision that represents a paradigm shift in the scope of Administrative Patents Judges’ duties in PTAB proceedings.
  • Barry led the patent team in an antitrust case involving allegations of sham patent litigation in the District of Minnesota for Graphic Packaging International, Inc. in a case brought by Inline Packaging, LLC. The district court granted summary judgment in favor of Graphic, finding no liability, and the decision was affirmed by the U.S. Court of Appeals for the Eighth Circuit in June, 2020.
  • 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 willful. The district court subsequently doubled the damages award and granted Saint-Gobain attorneys’ fees and costs for a total award exceeding $24 million.
  • At the International Trade Commission, Barry has represented both complainants and respondents in several matters. As one example, he represented SMC Corporation in a Section 337 proceeding involving connectors used in pneumatic-control systems and was instrumental in the Commission’s finding of noninfringement, which was affirmed on appeal.
  • Barry has successfully represented clients (both patentees and petitioners) at the USPTO in inter partes review (IPR) proceedings. Barry’s technical background, combined with his advocacy and cross-examination skills that have been honed through years of litigating patent disputes, make him ideally suited for IPR proceedings, either by themselves or in conjunction with district court litigation. For instance, he represented a defendant carpet tile manufacturer, Tandus Centiva Inc., in patent infringement cases in the Northern District of Georgia, inter partes reviews at the USPTO, and appeals to the Federal Circuit. Barry led a team that successfully defeated a motion for a preliminary injunction and then convinced the district court to stay the litigation. The USPTO subsequently canceled all of the challenged claims of three asserted patents, and the Federal Circuit affirmed.
  • Barry also has significant appellate experience at the Court of Appeals for the Federal Circuit emanating from district court litigation. In a seminal case involving the applicability of Section 102(g), Barry successfully argued that United States reproduction of technology conceived overseas does not qualify a United States manufacturer as a prior inventor under the statute. Solvay S.A. v. Honeywell Int’l, Inc., 622 F.3d 1367 (Fed. Cir. 2010)
