TriZetto Violated Patent of McKesson, Jury Says

McKesson Corp., the biggest U.S. drug wholesaler, won the first stage of a lawsuit that accused TriZetto Group Inc. of infringing a 1993 patent for software that detects fraudulent billing.

A Wilmington, Del., jury found that TriZetto violated the patent, paving the way for a second trial to determine damages the Newport Beach-based company must pay to San Francisco-based McKesson.
