GigaOm: Even as belt-tightening has led the New York Times to close sections and shed reporters, the Gray Lady is spending large sums on legal bills to fight a patent troll that claims to own the rights to sending internet links via text message. The Times has been fighting the case since 2010, arguing that the patent is unenforceable in part because the mobile phone companies that deliver the text messages have already paid the troll, known as Helferich Patent Licensing, to license it.
