Courts in Canada and the U.S. on Monday approved Nortel Networks Ltd.'s patent sale to an American consortium for $4.5 billion US. Reuters reported that Delaware bankruptcy court judge Kevin Gross, when approving the sale, said it would be a "$4.5 billion mistake" not give it the green light. Reuters reported that the court hearing used a telecast to run simultaneously in Delaware and in Ontario. Ontario court judge Geoffrey Morawetz approved the sale in Canada at the Ontario Superior Court of Justice. This month, a group of six companies—EMC, Ericsson, Sony, Apple Inc., Microsoft, and RIM Ltd.—successfully outbid Google Inc. for 6,000 Nortel patent and patent applications, paying a total of $4.5 billion US. Lisa Schweitzer, a lawyer at Cleary Gottlieb Steen & Hamilton LLP representing Nortel, said at the hearing that the sale is expected to close in about a month.
