 Choudhury, creator of Bikram Yoga, attempted to sue Florida-based Evolation Yoga for teaching what he claimed was his signature sequence of poses.

 Practicing Bikram Yoga involves performing 26 poses in a prescribed order inside a room heated to 105 degrees. Many studios not affiliated with Choudhury offer classes with a loosely similar philosophy under the banner "hot yoga." 
 
 On Thursday, the Ninth U.S. Circuit Court of Appeals in California ruled that Choudhury's sequence of poses weren't protected under copyright law. 
 
 "Copyright protects only the expression of this idea — the words and pictures used to describe the sequence —and not the idea of the sequence itself," wrote Judge Kim McLane Wardlaw in the court's decision.

 Choudhury helped popularize yoga in the United States with his 1979 book "Bikram's Beginning Yoga Class." But with success hasn't been without controversy. The founder has been hit with multiple sexual harassment lawsuits, all of which Choudhury has denied. 
 
 The court compared the Bikram Yoga sequences to recipes in a cookbook. Even if a particular cookbook is protected under copyright law, the recipes it contains are not. 
 
 "Although there is no cause to dispute the many health, fitness, spiritual, and aesthetic benefits of yoga, and Bikram Yoga in particular," Wardlaw wrote, "they do not bring the sequence into the realm of copyright protection."
– It turns out, you can't legally stop people from performing ancient yoga poses in a particular order. On Thursday, a Ninth Circuit Court of Appeals in California ruled against Bikram Choudhury, the founder of Bikram yoga, who was attempting to copyright his sequence of 26 yoga poses, NBC News reports. According to the Los Angeles Times, Choudhury—who didn't invent the poses, which are thousands of years old—claimed he alone had the right to decide who could teach them in the order he first published in 1979. Choudhury has threatened multiple lawsuits against yoga studios in the ensuing years, often with the studios caving or settling out of court. But one Florida studio fought back. Thursday's ruling was in support of Evolation Yoga's right to teach the 26 poses in any order they like, including Choudhury's sequence, NBC reports. The court compared it to a cookbook—in that the cookbook itself can be copyrighted but not the recipes inside of it—and also to surgery. “The copyright for a book describing how to perform a complicated surgery does not give the holder the exclusive right to perform the surgery,” the Times quotes from the judge's decision. Evolation's lawyer called the ruling “a very big victory for yoga studios and practitioners everywhere.” Choudhury was instrumental in yoga taking off in the US in the '70s, but he's been a controversial figure. In addition to his copyright claims, he's been sued multiple times for sexual harassment.
