Risk Mitigation Effectiveness of Foreign Well-Known Trademark Protection During Supply Chain Fluctuations

The global supply chain turbulence has increased the difficulty of protecting foreign well-known trademarks. Although there are many studies on cross-border trademark rights protection in academia, there is relatively little research on its risk mitigation effectiveness in the context of supply chain fluctuations. Based on case studies of commercial law and data statistics, the study explores the relationship between protection efficiency and market response through legal applicability. Due to the long litigation cycle and uneven law enforcement, there are differences in market regulation, weakening the protection of well-known trademarks and exacerbating supply chain uncertainty. Strengthening international legal framework cooperation and promoting law enforcement linkage can enhance protection effectiveness. In theory, enriching the theory of cross-border trademark protection and expanding research on brand rights protection in the context of global supply chains. In practice, it helps enterprises adjust their trademark layout, avoid legal risks, and improve market competitiveness. Due to the complexity of the legal environment and limitations in data acquisition, future research will strengthen data analysis, promote international cooperation in intelligent supervision, and build a more efficient cross-border well-known trademark protection mechanism.
