This paper investigates the effects of trademarks on the market value of firms. The results show that trademarks have a positive effect on firm value. Next, the firms' market values are regressed on indicators of trademark value such as trademark seniorities, the number of oppositions filed, and the number of product and services classes covered. We found that they at least partially reflect trademark value.
