Do you believe that slavishly copying your competitors is innovative? I won't say I agree with the lawsuits, but the definition of innovation is doing something that nobody has done before. If you're being sued for it, it means there's a chance you aren't being highly innovative.
No, but there are patents that are absolutely crap. The USPTO approved patents that were obviously not innovative. It's not automatically innovative, just because there's a patent issued for the item.
Examples:
One-click ordering
Electronic shopping cart
The wheel (Aus)
Dereferencing pointers
Having 4 icons in a row on the screen
Sun got into deep trouble because their developers didn't patent the software they wrote. Got sued for it by people that wrote the same software later, but then subsequently patented it. And they lost - big time. The engineers then went and made a game of it - who can come up with the silliest patents. Just to make the patent attorneys at Sun happy. These all got patented, and the results of this was used by Oracle to sue Google. Google was at the time accused of "slavishly copying" too.

This is the same system you want me to have respect for? No thank you.
