Canadian athletic apparel maker Lululemon has, reportedly, sued Peloton in Los Angeles Federal Court over the copycat products in the latter’s new apparel line.

Lululemon has sought triple damages for Peloton’s alleged ‘willful’ infringement of six design patents.

Here it is important to state that Lululemon’s move to sue Peloton comes days after the latter brought its own case in Manhattan Federal Court seeking a declaration that Lululemon’s claims lacked merit.

The entire controversy started in September after Peloton launched a private apparel label, following which Lululemon, reportedly, alleged that Peloton women’s bra and legging products like Strappy Bra and High Neck Bra, amongst others, infringed its patents.

Lululemon had then also said that another Peloton product – One Lux Tight – is a knockoff of its Align pants, which has been one of Lululemon’s all-time best sellers.

Earlier this month, Lululemon had, reportedly, sent a letter to Peloton wherein it threated to sue the latter unless sales of the alleged knockoffs were halted.

Peloton has, meanwhile, said in its lawsuit that customers wouldn’t have any problem in telling the companies’ products apart and also stated that Lululemon’s designs were not special enough to merit patent protection.

Lululemon was founded in 1998 as a retailer of yoga pants and other yoga wear, and it soon expanded to also sell athleticwear, lifestyle apparel and fashion accessories.
