==Abstract==
The pro-patent shift of the United States has created a patent thicket. This has made the use of other firms innovations more costly, due to higher transaction costs and the possibility of hold up. Using a panel data on publicly traded US manufacturing firms from 1979 to 1996, this study finds a negative impact from the patent thicket on the market value of the firm. I also find that firms with larger patent portfolios experience a smaller effect, likely because stronger bargaining position lowers the occurrence of the hold-up problem for these firms. The advantage of larger firms is even more prominent following the pro-patent shift. My results also capture heterogeneity in the impact of the patent thicket across industries.
