Federal investigators investigate Johnson & Johnson and its DePuy Orthopaedics subsidiary for possible violations in marketing the recalled ASR hip implants.

Federal investigators recently launched an additional inquiry into Johnson & Johnson (NYSE:JNJ) and its DePuy Orthopaedics subsidiary, taking a closer look at marketing practices surrounding a line of recalled metal-on-metal hips.
J&J confirmed in regulatory filings last week that the U.S. State Attorney’s Office for the District of Massachusetts and the Civil Division of the U.S. Justice Dept. had made “informal requests” for information about the ASR XL Hip devices.
Initial requests were made in August 2012 and additional inquiries have been made since then, according to a regulatory filing.
