Prominent user interface expert witnesses have extensive technical knowledge of how solutions are built and function behind the scenes. KOLs understand coding, UI frameworks, and software architecture. In legal cases involving claims about how an interface works or replicates functionality, these experts analyze the technical implementation and differentiate between protected design elements and functional features, which are generally not copyrightable.

Also leading accessibility user interface expert witnesses specialize in ensuring UIs meet legal standards such as the Americans with Disabilities Act (ADA). Pros evaluate whether interfaces are usable by people with disabilities and whether any violations occur. Leaders appear in cases where accessibility compliance is contested.
