Bloomberg L.P. violated no copyright laws when it posted an unauthorized recording of a conference call about the Swatch watch company’s earnings report on a data service for financial investors, a federal appeals panel ruled Monday.

“Fair use” exemptions protect Bloomberg from having violated federal copyright laws for posting the recording on the Bloomberg Professional service within minutes of the call’s completion in February 2011, a panel of the U.S. Court of Appeals for the Second Circuit decided unanimously.
