The patent which expired this week is, however, a different patent than the ones cited in the lawsuit against Typo Products LLC. The one that expired (CA 2497122), protected the design of a detachable keyboard accessory that would sit over top of a touch screen.
Those cited in the lawsuit were for protecting completely different designs: US patents: 7,629,964; 8,162,552; and D685,775.
