An anonymous reader notes that CSIRO has sued Verizon, AT&T, and T-Mobile in — wait for it — East Texas District Court. "Australia's peak science body stands to reap more than $1 billion from its lucrative Wi-Fi patent after already netting about $250 million from the world's biggest technology companies, an intellectual property lawyer says. The CSIRO has spent years battling 14 technology giants including Dell, HP, Microsoft, Intel, Nintendo, and Toshiba for royalties and made a major breakthrough in April last year when the companies opted to avoid a jury hearing and settle for an estimated $250 million. Now, the organization is bringing the fight to the top three US mobile carriers in a new suit targeting Verizon Wireless, AT&T, and T-Mobile. It argues they have been selling devices that infringe its patents."
