Difference between Trolls and non-Trolls is that first haven't own production. However, I'm doubting fact that non-Trolls using all or at least most its patents. Most of these patents used to lock competing technical solutions.
What about universities, carrying out research, inventing, developing technologies subsequently filing lots of patents?
To summarize, not everyone who has many patents is a troll.
