Qualcomm and Oracle are clearly bad actors. IBM? Probably. But I have no idea honestly. But Apple? The only patent suit I'm aware of that they initiated was against Samsung and this is a little more complicated. First, it was primarily a design patent suit. I'm a little more sympathetic to design patents than software patents (which I'm 100% against). And, let's face it, Samsung did pretty much just rip off the iPhone. There were some non-design patents thrown in there too, that's true. But the commenter I replied to suggested these tech companies were using patents to squash smaller competitors. And for most companies that isn't true. Even if you choose to include Apple in a list of companies that use patents offensively rather than defensively, Samsung isn't really a small competitor, so the point stands.
