Abstract:
User reviews of products on the e-commerce platforms are a critical determinant of inter-platform competition, as a large number of consumers base their purchasing choices on the related reviews written by other users. The network effects between the number of reviews and new users give a sustainable competitive advantage to incumbent platforms. While business literature has recognised the commercial value of the user reviews, legal scholarship has paid little attention to levelling the playing field between incumbents and new e-commerce platforms by exploring the portability of user reviews. This paper bridges this gap. We explore the possibility of porting user reviews through two legal mechanisms—first, traditional Intellectual Property law; second, the new Right to Data Portability (RtDP) as enshrined in the GDPR. After recognising the limitations of these mechanisms in enabling the portability of reviews, we suggest that pure data aggregators, such as Personal Information Management Services (PIMS), are best placed to make user reviews available to multiple platforms.
