Trade Secrets and Mutual Investments

Abstract

This paper employs an contracting framework to study the question of how courts should adjudicate disputes over valuable trade secrets (such as customer lists). We focus principally on contexts where trade secrets are formed endogenously, through specific, non-contractible investments that could potentially come from either employers or employees (or both). Within such contexts, we argue, an optimal trade secret law diverges in many important respects from existing doctrine. In particular, an doctrine would (1) expressly consider the parties' relative skills at making value enhancing investments rather than the mere existence of a valuable informational asset; (2) tend to favor weak entitlements (such as fractional property rights and/or liability rules) rather than undivided property rules; and (3) frequently have a dynamic structure that progressively favors employees during the lifetime of the disputed asset. Moreover, we argue, the considerations implicit in such a doctrine are relatively simple and need not impose prohibitive administrative costs on either the parties or on courts.
