@Mike,

There are other claim limitations beyond just the stylus such as, in claim 7: obtaining a direction of the trace ... searching key code information ... displaying on the image of the keyboard an image of the key code generated ... etc. Also, the patent to which you linked appears to have been filed about two years later than the Samsung '179.

So if the definition of stylus is "everything" or "anything" then is it really patenting a stylus/touch screen? Or is it jut patenting a touch screen?

If it just a touchscreen with a keyboard (where the stylus isn't the defining characteristic) then why isnt it just this patent?
