Garment sellers in China and many other countries saw business opportunities in the Sochi opening ceremony glitch, when only four of five rings were lit up, and "Sochi problem rings T-shirts" have become a hit on the Internet.

But lawyers said in spite of the glitch, Sochi still had the copyright for the five rings, and people cannot use the design without authorization from Sochi.
