What is the strategic rationale for using 'Defensive Trademarking' relative to Amazon Brand Registry?

The strategic rationale for using 'Defensive Trademarking' relative to Amazon Brand Registry is to secure broad legal protection for a brand beyond its immediate product categories and prevent others from using similar marks that could dilute or infringe upon the brand's identity. While Amazon Brand Registry primarily focuses on protecting a brand's listings and content within the Amazon marketplace, defensive trademarking involves registering the trademark in multiple classes of goods and services, even if the brand doesn't currently operate in those areas. This proactive approach deters potential competitors from using similar brand names or logos in related industries, strengthening the brand's overall legal position and preventing future brand confusion. Defensive trademarking provides a wider scope of legal protection compared to solely relying on Amazon Brand Registry, which is limited to the Amazon platform.
