A New York lawyer who used a cartoon image of a heavily bandaged patient to advertise his personal injury practice may be entitled to copyright protection for the drawing, a federal judge has ruled.

Richard P. Neimark of Rockland County, N.Y.’s Neimark & Neimark began using the cartoon in 1988, publishing it in Yellow Pages advertisements. The drawing depicts a bandaged patient lying in a hospital bed with a prescription to “Call Neimark” attached to his chart. Neimark registered the drawing with the U.S. Copyright Office in 1990.
