This document summarizes a presentation on the entire market value rule (EMVR) in patent damages. It discusses recent court cases that have applied gatekeeping to prevent unsupported damage statistics. While ambiguities still exist around measuring consumer demand, courts now generally require evidence that the patented feature drove consumer demand for the infringing product. The presentation also notes the debate around whether the EMVR overcompensates patent owners and interferes with technology development, but argues abolishing the rule is not the answer. It concludes that Congress should codify guidelines for applying the EMVR more narrowly.
