James V. Leito IV



James is a partner who represents businesses and individuals in complex commercial cases, class-action lawsuits, and intellectual property disputes.  He has represented clients in multiple industries, including the telecommunications, healthcare, oil and gas, and aviation industries.

James has represented clients in three jury trials, two bench trials, and an evidentiary hearing: 

  • served as lead U.S. counsel in defense of a Dallas-based client in a twelve-week bench trial in Alberta, Canada, concerning breach of contract and fraud claims,
  • defended a public hospital district in an evidentiary hearing on a plea to the jurisdiction, including cross-examining a plaintiff who was a former executive of the hospital district,
  • represented a fuel-loyalty company in a three-week breach-of-contract and fiduciary-duty trial in state court in Dallas, Texas,
  • served as lead U.S. counsel in defense of a Dallas-based client in a four-week bench trial in Alberta, Canada, concerning fraud and conspiracy claims,
  • defended an insulation manufacturer in a one-week patent infringement trial in Marshall, Texas, and
  • defended a hospital in a three-week breach of contract trial in state court in Austin, Texas.

James has also tried over 25 trials on behalf of the Cities of Plano and Carrollton through the firm's loan-a-lawyer program.  On appeal, James has successfully argued before a state court of appeals to affirm a summary judgment, and he has been the lead brief-writer on several other appeals.

In addition to his trial and appellate work, James has taken the lead on numerous pre-trial matters, including obtaining temporary restraining orders and arguing various issues before state and federal courts (including jurisdictional challenges, patent claim construction, motions for summary judgment, challenges to expert testimony, motions in limine, and discovery motions).  Outside of the courtroom, James has taken or defended over 75 depositions and has experience managing large-scale document reviews, including management of contract-review teams of over 25 lawyers.  

James often handles pro bono cases through the Dallas Volunteer Attorney Program (such as divorces, will drafting, and property disputes), and he has represented a death-row prisoner in habeas corpus proceedings through court appointment.

Before joining the Dallas office in 2011, James clerked on the Texas Supreme Court during the 2009-10 term with Justices Scott Brister and Eva Guzman.  He then clerked for the U.S. District Court for the Northern District of Texas with Senior District Judge Royal Furgeson.
