Does shareholder overlap alleviate patent holdup?

Abstract

Patent protection can generate holdup problems for follow-on innovators when technologies protected in early patents complement their inventions. This study investigates whether institutional shareholder overlap between firms with precursory patents and follow-on innovators can reduce such patent holdup problems. Using patent citation links to track complementary patents, we find empirical support for such a holdup attenuation hypothesis of institutional shareholder overlap. Follow-on innovators with greater institutional shareholder overlap to precursory patent owners enjoy greater success with their patent portfolio, face less patent conflict as measured by patent litigation , and feature higher levels of R&D investments. The holdup attenuation effect is stronger if product complexity makes securing ex ante patent licenses more difficult.
