Online marketplaces account for the majority of e-commerce transactions and the volume of goods sold naturally make them a vital arena for counterfeit prevention and brand protection. The 100 largest online marketplaces had sales of over USD 1.66 trillion in 2018, a number that has since continued to grow at an incredible pace. Brand protection on online marketplaces therefore has the potential to mitigate loss of revenue from IP infringement, as well as reputational damage thanks to the large number of consumers involved.
