Samsung on Thursday filed for an interlocutory application with a Federal Court in Australia asking for a sudden hearing in its legal conflict with Apple. While details of the request weren't clear, it would be held late Friday morning in Sydney time by Justice Annabelle Bennett, who has overseen many of the previous hearings between the two. It's suspected so far that the hearing may be an attempt to block sales of the new iPad and use this as a surprise bargaining chip.
