Jing Ran
In sharing her paper, Jing Ran mentioned that it examines how China's intellectual property protection affects the patent applications of US multinational corporations (MNCs) in China when these companies already possess overseas technology patents. Jing Ran and her collaborators analyzed the issue from a technical perspective, highlighting the innovativeness of the technology. The paper constructs an indicator to measure technological innovation capability. This allows us to observe the quality of early-stage patents, overcoming the shortcomings of traditional patent quality metrics (i.e., citation rates). By merging the patent datasets of US MNCs in China with those of BvD, the paper finds that US MNCs are reluctant to patent their innovative technologies in China. However, strong intellectual property protection in the provinces where foreign investment is located mitigates this resistance. After considering the endogeneity of location selection, the main findings remain robust.

Sui Xiaomei
Sui Xiaomei, Assistant Professor at the University of Hong KongThis article provides an excellent analysis of the different responses of technologies to intellectual property protection. It's encouraging that different technologies react differently, as this hasn't been widely discussed in existing literature. When discussing how to eliminate other explanations, Sui Xiaomei stated that the relatively few innovative technology patents filed by US multinational corporations in China are not due to concerns about technology spillover to Chinese companies, but rather because they face less competition from Chinese companies. Sui Xiaomei pointed out that the number of closed cases may not reflect the actual level of patent protection, and therefore doesn't necessarily reflect the effectiveness of patent protection. Of course, it may depend on the number of patent applications, the severity of patent disputes, etc. However, if the article could further control for confounding factors, the results would be better. Sui Xiaomei also suggested alternative measures: utilizing patent law amendments that benefit patent holders and ownership reforms that clarify the impact of property transfers. Finally, Sui Xiaomei stated that using the median to classify innovative and non-innovative technologies is reasonable. However, it's also possible to try using the 25th percentile and the 10th percentile to show robustness and examine the quantitative differences in empirical estimates. From the perspective of patent citation counts, only a small number of patents are truly "innovative."
