Peloton filed a lawsuit against Lululemon after Lululemon threatened to sue the connected fitness leader over its new apparel line.

In its suit filed Wednesday in Manhattan federal court, Peloton said that in a letter dated November 11, 2021, Lululemon said it would sue Peloton unless it stopped selling its new apparel.

“On top of the numerous clear and obvious differences in design, Peloton and Lululemon’s brands and logos are also distinctive and well-recognized, making confusion between products a virtual impossibility,” Peloton wrote in court papers.

Peloton said Lululemon’s claims that five of its women’s bra and legging products—Strappy Bra, High Neck Bra, Cadent Peak Bra, Cadent Laser Dot Bra, and Cadent Laser Dot Leggings—infringed six Lululemon design patents “lack any merit.”

Peloton is asking for a court declaration that it has not infringed Lululemon patents and trade dress and that Lululemon’s patent claims are invalid.

“At Lululemon we are known for our product innovation and iconic design,” Lululemon said in a statement on Friday. “We will defend our proprietary rights, to protect the integrity of our brand and to safeguard our intellectual property.”
