I've provided a reference that clearly states that highly competitive industries can survive just fine without patents, [even if as you point out, related industries use patents].
Although true, that "industry" does not analogize to the rest of the world. From your article, F1 doesn't use patents because, if they get a patent on a technology, all of the other competitors will vote to have that technology disallowed. That simply doesn't exist in other industries, and without that sort of punitive over-arching regulation of an industry, there's no reason to suspect that the F1 experience should apply elsewhere.
And there are plenty of references here on
Yes, but that's mostly out of date. The law on willful infringement is changing, quite reasonably too. At this point, merely reading a patent application will not be enough to support a finding of willful infringement.
