Maybe because the introduction of the Cisco iPhone was a two-bit tactic?
[.... much common sense about Cisco's underhandedness ....]
It should be an interesting court case, although not necessarily a long one...
From a jury's perspective the sticker-on-the-box trick will appear
incredibly shabby, even if it were to be shown to be standard
trademark industry practice (is it?)
Also, aside from technicalities (like Apple owning the trademark
in all the rest of the English-speaking world), a defense based upon
"likelihood of confusion" seems like a slam-dunk for Apple.
Application of the "reasonable man" standard would show negligible
commonality when the Cisco CIT 200 is trotted out for comparison.
Also in Apple's favor is the time element. By the time a jury trial
happens, the iPhone will have been in the vernacular for years, with
much dilution only not in the relative merits of Cisco's obsolete offering
compared to Apple's innovation, but in the wholesale linguistic
effects which brought us generic scotch tape, kleenex, xerox copies,
and the frisbee.
