The Typo keyboard case is not good, but the idea for it may be: it adds a BlackBerry-style physical keyboard to the bottom of your iPhone. It was too familiar for BlackBerry, which in January sued Typo for patent infringement. The case is ongoing, but this past Friday Judge William Orrick granted BlackBerry a preliminary injunction halting sales of the Typo. In the ruling, Orrick said that BlackBerry had established a likelihood of proving that Typo infringes the patents at issue and Typo has not presented a substantial question of the validity of those patents.
