Apple’s multi-touch patent, which is currently at the forefront of hysterical (and unfounded) implications that Apple has “threatened” to sue Palm to the ground. They haven’t done any such thing. They patented the heuristics to make sense of multi-touch inputs, which doesn’t necessarily mean you can’t reach the same goals in a different way. Still, the thing pretty much reads like a functional description of the iPhone in some parts (namely the possible applications running on the example devices). My advice? Let the lawyers sort it out.
