There is no abuse of the law, there is law, and there is not law. Using the law is not an abuse, regardless of what it may seem from the cheap seats where we are all sitting.
The law is intended, in the Constitution, to 'promote the progress of [technology]'.
Using the patent system to browbeat your competitors out of business by wielding bullshit imaginary software patents does not promote the progress of anything but Apple's business.
There is most definitely such a thing as abuse of the law. The law should be followed in spirit, not only in letter. The courts often underscore this, but unfortunately by that point it's already too late, as the abuse has been done.
If you don't like it, fix the laws.
