Apple [AAPL] now have charge of the iPad trademark (serial number 76497338) and are now on the legal side of things in terms of calling the Apple iPad just that.
Previously the trademark was owned by Fujitsu who registered it in March 2003 when they created a wireless handheld computer specifically used by retailers called the iPad.
From what we see the iPad trademark was assigned over to Apple on March 17 this year just in time for the iPad to launch next week.
There has been much speculation over the last few months about the iPad trademark. Apple initiated opposition proceedings challenging the validity of the mark in September last year. However, the proceedings never developed into anything substantive and Apple simply filed three requests for extensions of time, presumably while they were in talks with Fujitsu.
