Platform Accountability in E-Commerce: Interlinking IP Liability, Counterfeit Goods, and Consumer Refund Rights

The global expansion of digital commerce has transformed the global consumer behavior and also accentuated complex questions of accountability of e-commerce platforms particularly within the overlapping domains of intellectual property (IP) liability, counterfeit trade, and consumer refund rights. This doctrinal study critically examines the legal and conceptual foundations that regulate platform responsibility for unlawful conduct by third-party sellers. Utilizing a comprehensive and comparative legal analysis, it investigates how diverse statutory frameworks such as the EU E-Commerce Directive, the US Digital Millennium Copyright Act, and China’s E-Commerce Law, conceptualize the liability of intermediary platforms through standards of knowledge, control, and active participation. The study elucidates how these standards intersect with issues of contributory infringement and consumer protection in digital marketplaces and analyze how different regimes shape accountability and consumer trust. In analyzing the proliferation of counterfeit goods, the research interrogates prevailing doctrines of strict and vicarious liability alongside evolving policy mechanisms that aim to reconcile enforcement efficacy with technological feasibility. It further highlights the fragility of consumer refund systems in cross-border transactions, where jurisdictional differences often undermines redress and deterrence. Through a comparative and normative lens, the paper identifies structural divergences between legislative and self-regulatory models, including proactive monitoring obligations and algorithm based moderation. Significant research gaps persist in defining the threshold of ‘active’ platform involvement, assessing algorithmic accountability, and achieving regulatory coherence across jurisdictions. This study concludes by advocating for a harmonized, interdisciplinary approach that integrates doctrinal clarity, regulatory precision, and technological innovation to ensure equitable accountability and enhance consumer and IP protection within the global e-commerce ecosystem.
