Starbucks claims union violates coffeemaker’s trademarks

Starbucks filed a lawsuit against the union Starbucks Workers United in Iowa federal court, alleging trademark infringement by using the company's name and logo on promotional materials, social media, and merchandise. The union, which organized 12,000 baristas, claims Starbucks has blocked contract negotiations and filed a separate lawsuit in Pennsylvania to assert its right to use the brand. Starbucks argues the union's use of its trademarks dilutes its brand and falsely implies endorsement of unrelated social and political issues.
