Nortel on Friday completed its selloff of patents to an Apple-led coalition but faced a much tougher Department of Justice investigation into antitrust issues. What the new steps involved wasn't certain, although it's likely to focus more closely on whether the group, which also included Microsoft, RIM, and Sony, planned a patent lawsuit campaign or would use the patents solely as a defensive measure. The WSJ sources blamed Apple's involvement in the group and the very high $4.5 billion winning bid as red flags.
