The results show that PE-backed LBOs have a positive causal effect on both patenting and quality-adjusted patents measured by forward citations. This implies an increase in innovation activity rather than an increase in strategic patenting. The impact is predominantly driven by private to private LBO transactions. The findings are consistent with PE firm involvement relaxing financial constraints in firms, facilitating their investment in innovation activity.
