quote: I think this is a little disingenuous. You state 'someone else came up with' as if that is a matter of fact. Even if that is what you believe, it isn't necessarily what Apple believes.
quote: I think 'Every company does it' is a compelling argument. You have to bear in mind that companies are not human entities - they do not necessarily adhere to 'morals' except where doing so increases profit. It is almost their duty to maximise the income from their intellectual property such as patents, and they have to work off the assumption that their competitors will do the same - legally, of course.
quote: Your claim of a 'short term' aim when referring to a patent filed 7 years ago with no knowledge of what would happen in subsequent years would appear contradictory
quote: all the companies in question can handle the legal costs since they have in-house legal teams anyway, and no actual damage has been done yet.
quote: What Apple is doing, arguably, is allowing their own patent every chance to realize its full value.
quote: Apple feel a little aggrieved that everyone else duplicated what they believed was a protected idea.
