People
LeElle Slifer is a seasoned trial lawyer with experience in a wide range of disputes, including breach of contract, oil and gas, breach of fiduciary duty, patent and copyright infringement, non-competes, theft of trade secrets, class actions, antitrust, securities, RICO, and even the seizure of cargo barges and private jets, to name just a few. LeElle’s clients describe her as their “go-to” lawyer who can handle any problem, “providing time-critical business and strategic counsel that can make all the difference in high stakes litigation.” She understands that getting the best result means more than just the legal outcome, it means focusing on the client’s business goals at every juncture.
LeElle has litigated in federal and state courts nationwide, trying matters before both judges and juries. She has participated in numerous domestic and foreign arbitrations, including before the International Chamber of Commerce in London. One of her trials—DDR Holdings v. Hotels.com, in which her team won a jury verdict of patent infringement in the Eastern District of Texas—was the first case to survive a Section 101 challenge at the Federal Circuit after the Supreme Court issued Alice Corp. v. CLS Bank Int’l and was the only case to do so for almost two years. She has also briefed and argued many federal and state appeals throughout the country, including to the Supreme Court in Comcast Corp. v. Behrend.
LeElle knows that litigation forms just one aspect of her clients’ businesses. She thinks tactically, keeping her clients’ objectives and concerns top-of-mind as she counsels them through litigation. And her clients can attest to the success of LeElle’s results-oriented approach:
“I’ve had the privilege of working with many of the country’s top lawyers, and LeElle stands at the very top of that tier. A brilliant strategist and master negotiator, LeElle assesses the moment instantly, calibrates her approach, and then effectively executes with surgical precision and absolute integrity. She moves effortlessly between Wall Street boardrooms and small-town courtrooms—, bringing the same commanding presence and relatable authenticity to both. Put simply, if you’re looking for strong, smart, efficient, business-first advocacy—whether for a bet-the-company case or a simple dispute—I couldn’t recommend her more highly.” – Jason Schwartz, General Counsel for Stonebriar Commercial Finance.
