Market Landscape

The Supreme Court's 2020 Booking.com ruling expanded trademark protection for generic-sounding .com brands, a shift that has fueled advertising and trademark disputes among brands competing for online consumer attention. Kagan's background in that case places him within that competitive litigation market.

For businesses in New York City and beyond, the appointment gives advertisers and marketers access to a litigator experienced in false advertising and National Advertising Division challenges. Companies facing competitor claims about their marketing now have another firm with that focus in the New York market.

The takeaway

Trademark protection for brand names can hinge on how consumers perceive a term, so marketers should review how their branding is registered and promoted before launching campaigns.
