The effects of patent trolling on enterprise technology innovation are hotly debated at both the theoretical and public policy levels, but relevant empirical research has been relatively scarce. Based on the 2017 China Patent Survey data, this paper examines how different levels of contact with patent trolls affect technological innovation of Chinese enterprises. We find that 54.05% of enterprises have heard of patent trolls, while 7.52% of enterprises have had direct contact with patent trolls. The results indicate that the emergence of patent trolls is beneficial for awakening Chinese enterprises’ awareness of intellectual property rights and enhancing technological innovation through increasing R&D investment and patent accumulation. However, direct contact with patent trolls is not conducive to improving the quality of patents. The contact also has a significant negative impact on patent implementation, a consequence mainly reflected in the decline of patents self-implemented by target enterprises and an increase in patent licensing. In other words, enterprises are moving from self-implementing patents towards patent licensing. To some extent, this reveals a ‘patent troll infection’ that hinders the implementation of patented technology. This paper contributes to examining the overall effects of patent trolling on technological innovation in the context of developing economies.
