Daryl Hall and John Oates have filed a lawsuit saying their music publisher failed to protect their rights to their 1982 hit "Maneater."
The pop duo's lawsuit says they learned in April 2007 that an unidentified singer-songwriter had used "Maneater" in a 2006 recording.
The papers, filed in Manhattan's state Supreme Court, claim Warner/Chappell Music Inc. breached its publishing contract with Hall and Oates by refusing "in bad faith" to sue for copyright infringement.
The singers seek unspecified money damages and want to terminate their agreement with Warner/Chappell.
A Warner/Chappell spokesman did not immediately return a call for comment on Thursday.
Hall and Oates' hits, which came mostly in the 1970s and '80s, also include "Rich Girl," "Private Eyes" and "I Can't Go for That (No Can Do)."
