Abstract：Patent litigation has increasingly emerged as a crucial tool and strategy for ICT firms in market competition.This study selects 57 global ICT companies from 2008 to 2021 as research samples to explore the impact of corporate litigation experiences,under different litigation roles,on technological innovation.Baseline regression results indicate that firms with extensive experiences in both initiating and defending litigation exert a positive influence on technological innovation activities,as they are more inclined to increase R&D investment and patent output to enhance their market competitiveness.The results of the heterogeneity analysis indicate that proactive patent litigation has a greater promoting effect on the technology innovation input and output of market-leading enterprises.Market-following enterprises increase both their innovation input and patent output after being sued.Proactive patent litigation experience exerts a more pronounced incentive effect on the technological innovation activities of enterprises with high financing constraints.Compared to ICT service enterprises,the litigation experience of ICT manufacturing enterprises has a stronger promoting effect on technological innovation.
