  • Recovering attorneys' fees can no longer be an afterthought for trial lawyers and their clients. Today, the ability to recover attorneys' fees may be the deciding factor in whether or not to file a lawsuit and almost always plays a critical role in the decision to settle or try a case. In fact, it is no longer unusual for an attorneys' fees recovery to exceed actual damages. Mindful of this change in the attorneys' fees landscape, attorneys' fees experts Trey Cox and Jason Dennis have authored How to Recover Attorneys' Fees in Texas -- a complete, step-by-step guide for practicing attorneys to help them win and defeat attorneys' fees claims at trial., Co-Authored with Jason Dennis, How to Recover Attorneys’ Fees in Texas, Published by ALM, Legal, 2025
  • This book was tailor-built to help trial lawyers prepare for, make, and respond to evidentiary objections. It is designed to be used for quick reference on the go in the courtroom and to consult at length in your office. The Rules of Evidence can be tricky in practice. There are numerous "cheat sheets" that print all the rules on one page, but don't provide any additional guidance and are in difficult-to-read fine print. On the other hand, there are treatises packed full of case law and helpful materials, but those are cumbersome to use. This book is meant to fill that gap and be the go-to practical resource for trial lawyers., Co-Authored with John Adams, Mastering Federal Evidence, Trial Advantage Press, Legal, 2022
  • Texas courts are bracing for a flood of trade secret litigation. And while COVID rattles the economy, corporations are gearing up for the inevitable.

Texas is already the No. 1 trade secret hotspot in America, boasting close to 20 percent of all decisions nationwide. Authored by experienced Texas trial lawyers, Texas Trade Secret Litigation is the only manual in print for this fast-growing area of intellectual property law. Trey Cox and Chris Patton provide a step-by-step guidebook covering statutes, procedure, and overall litigation strategy. Fully updated with case law and sample forms, Texas Trade Secret Litigation is the essential reference for lawyers contending with the increasing trade secret docket in Texas courts. , Co-Authored with Chris Patton, Texas Trade Secret Litigation, A step-by-step guidebook covering statutes, procedures, and overall litigation strategy, Full Court Press, Legal, 2020
