Handheld legal hijinks

Brighthand has just updated its ongoing summary of all the wacky legal battles that have plagued the handheld industry over the years (noting that Research In Motion, the company behind the BlackBerry, seems to be involved in half of them), reminding us all of the antics we'd forgotten (or never knew in the first place) like how Piliot Pen Corporation forced Palm to drop the "Pilot" from "PalmPilot", how Palm sued Microsoft when they originally called the Pocket PC the "Palm PC", and how RIM sued Handspring and Palm for violating its patent on thumb keyboard design.
