Abstract

Agents routinely appraise and trade individual patents. But small-sample methods (generally derived from basic accounting and finance) are often crude, and their results may bear little relationship to economic fundamentals, especially in litigation. Meanwhile, large-sample methods usually lack much invention-specific data on which to condition value estimates. Regardless of sample size, proper valuation methods require both conceptual delineation and empirical ingenuity.
