RIM Redux or Deja-vu

RIM is in hot water again. Another patent dispute with too much deja-vu. Last time they settled paying out hundreds of millions of shareholder's cash. The dispute could have been settled early on for a measly ten million. Is RIM a serial offender and what else is there? Should an independent board committee be investigating potential patent infringements? No company should have to pay out mega-buck settlements every few years. Management characterizes the patent fights as nuisance legal battles. What is the board of directors doing to ensure RIM is not a sand castle of intellectual property?
