In software patent, source code, trade secret, and copyright litigation, the expert witness often decides whether a technical argument is believed. The right expert explains complex code to a judge and jury in plain language, holds up under cross examination, and survives a Daubert challenge. The wrong one can sink an otherwise strong case.
So how do you tell them apart before you sign an engagement letter? It comes down to a handful of things that are easy to check once you know to ask: direct, hands-on depth in the exact technology at issue, real litigation source code review experience, a testimony record that has held up under oath, genuine independence, and the ability to teach a non-technical jury.
