"Something missing from Palm's CES presentation of the Palm Pre: jaunty claims that they've patented their innovations up the wazoo. Maybe it's because they have a massive cache of smartphone patents in their portfolio already and didn't want to toot their horn. Maybe they were just being coy. Maybe, though, they were just waiting for their various patent applications to get approved before they brought it up. […] A couple more images from the patent (which goes to Palm but was filed on behalf of the inventors, one of whom was the just-mentioned software engineer Sachin Kansal) after the break. If you look closely, the patent application also describes a single unified message listing screen that will show you all your messages, no matter what kind they are, in a single list."
