Niall has litigated complex patent and trade secret cases throughout the United States, including cases involving combustion engines, snowmobile design, medical devices, including interventional cardiology technologies and magnetic resonance imaging (MRI), internet-based tracking systems, e-commerce, computer hardware and software technologies, and telecommunications systems. He has also litigated commercial cases involving breach of contract, non-disclosure/confidentiality (NDA) agreements, non-compete agreements, and intellectual property licenses in federal and state courts.

Niall has extensive experience in all aspects of complex technical cases from initial investigation to strategy to complex discovery to winning at trial. He has successfully argued summary judgment motions and patent claim constructions, and deposed numerous technical expert witnesses, inventors, engineers, and company executives. Niall has also argued before the United States Court of Appeals for the Federal Circuit (the court where all patent appeals go).

Niall was lead trial counsel in a three-week patent trial in November-December 2017, where the jury returned a verdict for his client Arctic Cat (a Textron subsidiary) in a lawsuit brought by rival Bombardier Recreational Products. Niall successfully argued for Arctic Cat on the appeal of the jury verdict by Bombardier, and the Court of Appeals for the Federal Circuit affirmed the Judgment and jury verdict for Niall’s client Arctic Cat.
