Four years after the first subpoena, the government’s investigation of health care fraud at Johnson & Johnson has reached zero hour.

Lawyers from Quinn Emanuel Urquhart Oliver & Hedges who represent the company are scheduled to meet with Assistant Attorney General Tony West and other Justice Department attorneys in Washington, D.C., next week, say lawyers familiar with the situation. Their goal: to persuade prosecutors not to indict Johnson & Johnson for off-label marketing at Scios Inc., a Bay Area subsidiary.
