The legal battle between Costco and Acushnet Holdings Corp, the maker of Titleist golf balls, has taken a heated turn.
Five months after Costco sought a judgment to confirm that its Kirkland-brand balls didn’t infringe on Titleist’s patents, Acushnet has responded with a countersuit.
This high-stakes lawsuit centers around allegations that Costco’s Kirkland Signature golf balls infringe on ten of Titleist’s patents, specifically related to ball core and dimples.
Acushnet isn’t just seeking a simple resolution; they’re asking for substantial damages, including three times the profits Costco made from the Kirkland balls.
Additionally, Acushnet accuses Costco of false advertising, challenging the Kirkland Signature Guarantee that claims to match or exceed the quality of leading national brands.
