SAN FRANCISCO (AP) — The founder of a popular form of yoga that is performed in a room heated to more than 100 degrees lost a court appeal Thursday to copyright a sequence of 26 poses and two breathing exercises. The 9th U.S. Circuit Court of Appeals ruled that the sequence used in hot yoga classes is a process intended to improve people's health, so copyright law does not cover it. A copyright on the yoga sequence would be akin to giving a surgeon the exclusive right to perform a complicated surgery, the court said.
