James B. Hatten is an intellectual property litigator who brings a rare combination of technical depth, strategic clarity, and thoughtful advocacy to complex patent, copyright, and trade secret disputes. With a formal background in computer engineering, James approaches litigation with the mindset of an engineer: understanding how systems work, identifying points of failure, and building solutions grounded in logic and evidence.
James represents domestic and international clients in high-stakes intellectual property matters involving computer hardware and software, telecommunications, networking technologies, and other sophisticated technical systems. He has litigated cases in federal courts across the country, including California, New York, and Texas, and has substantial experience in the Eastern District of Texas, one of the nation’s most demanding venues for patent litigation. He obtained summary judgment of noninfringement for a payments network company in a patent infringement action related to gift card technology, with affirmance on appeal.
What distinguishes James’s practice is his ability to move seamlessly between technical analysis and legal strategy. He is deeply involved in all phases of litigation, from shaping case theories and leading discovery to briefing dispositive motions and working closely with experts. Clients rely on him for courtroom advocacy and practical guidance on how intellectual property and litigation relate to business strategy. He regularly advises on the use of intellectual property to protect technology investments, manage risk, and support long-term growth.
James is drawn to the problem-solving and truth-seeking aspects of litigation and takes seriously the role of lawyers in the court system. He is known for his diligence, pragmatism, and ethical approach, offering candid advice grounded in both technical understanding and legal judgment. His style is deliberate and conscientious, with a focus on helping clients make informed decisions at every stage of a dispute.
Before joining AddyHart, James practiced at Baker & Hostetler LLP, where he litigated a broad range of intellectual property and technology-related disputes and advised clients on patent prosecution, intellectual property due diligence, indemnification claims, and anti-piracy strategy. Across matters, he brings curiosity, precision, and a commitment to learning each client’s technology and objectives as thoroughly as possible.
Outside the Office
Outside of his legal practice, James enjoys learning new skills and working on projects that allow him to understand how things work. He is naturally curious and often dives deep into subjects simply to master the details, whether teaching himself woodworking techniques for home projects or learning lighting and photography principles to thoughtfully document meaningful personal memories.
James enjoys working with his hands and values the process of learning something new from the ground up. He brings the same patience, attention to detail, and problem-solving mindset to his interests outside the office as he does to his legal work.
