Businesses are also not shy about suing for gargantuan sums. Some of these lawsuits are probably filed just for publicity value, as when McDonald's sought a temporary restraining order to prevent the airing of ads comparing its Big Mac unfavorably with Burger King's Whopper. Others are examples of commercial pride run amok. Suing has practically become part of the marketing strategy for some products. Questionable litigation also taints the field of patent and copyright law.
Some companies actually specialize in suing for profit.
Eugene Lang, renowned for offering some inner-city school kids college tuition, is most prominent. His company, Refac Technology Development Corp., develops lawsuits, not technology. Refac has made millions buying patents, filing lawsuits and settling out of court. Critics of personal injury law often argue that lawsuits are spurred by unrealistic expectations about life's misfortunes. Consider the Wedtech Corporation, focus of several successful investigations into public corruption.
