Is NTP going after the Palm Treo now?

I was browsing the news feeds today and ran across the name NTP so I popped open and checked out the CNET article. You may remember NTP as they were the company that sued RIM for patent infringements on their BlackBerry devices. It seems that NTP isn't content with the settlement they received from RIM and now appear to be targeting the Palm Treo. Microsoft and Nokia may be future targets too since they have some great QWERTY devices available that support push email functionality.
