Terry W. Griffin, PhD Expert Witness
Terry represents both plaintiffs and defendants in agricultural product liability and chemical trespass disputes, providing independent analysis of causation and damages. His work includes evaluating third-party damage claims involving herbicide drift, crop injury, and other agricultural losses by integrating agronomic expertise with digital agriculture technologies. Using satellite imagery, remote sensing data, precision agriculture records, yield monitor data, Actual Production History (APH) information, and on-farm experimentation datasets, Terry quantifies economic damages, assesses production impacts, and develops defensible valuations. This experience allows him to assist attorneys, insurers, agricultural businesses, and producers with objective damage assessments grounded in both field-level evidence and advanced data analytics.
Farm data valuation has been an emergent topic across the agricultural sector for several decades. Previous analyses focused on estimating damages from misappropriation, although no existing estimates of valuation within the farm gates for data, especially inaccessible data. Based on actual events when yield monitor data became inaccessible to farm operators, damages were estimated in anticipation of litigation. Valuation was estimated given how yield monitor data was intended to be used in the decision-making process. Specifically, valuation was estimated within the context of conducting farmer-managed on-farm experimentation. Farmers implicitly value on-farm experiments given the financial and non-monetary, i.e. human capital, investments. Key outcomes included 1) farm operators must be perceived to use data and 2) data must be treated as valuable. Each on-farm experiment was valued at over $40,000.
