Abstract
An initial public offering (IPO) is a critical event in a firm’s life cycle which can reshape its innovation strategy. Research suggests that after going public firms experience an increase in patent productivity. Our paper explores perceived litigation risks as a determinant of this outcome by examining US semiconductor firms. Results show that perceived patent litigation risks are positively associated with patent productivity after the IPO. Interestingly, we also find that the amount of capital raised during the IPO is positively associated with patent productivity after the IPO, successfully replicating previous findings on this relationship. These results are robust to model specifications where we attempt to account for the dynamics of self-selection of firms into IPO by considering matched control firms with similar pre-IPO characteristics, but that never went public.
