As a member of Sterne Kessler’s AI leadership team, Todd helps clients safeguard their AI technologies, arrange licensing agreements, and handle the legal and regulatory complexities surrounding AI. His deep knowledge of these topics is supported by his extensive technical and legal background in AI and machine learning technologies, such as pattern recognition, predictive analysis, and neural networks. He has particular expertise in industries like biotech, healthcare, and consumer technology.

Todd’s expertise extends to drafting non-infringement and invalidity opinions, handling inter partes review and reexamination proceedings at the USPTO, and assisting with litigation in district court.
