Many people -- including my younger self -- would judge this very negatively, because they think -- correctly, in my view -- that the current patent system is, essentially, evil. Recently, I've been motivated to collect some of my thoughts about the patent system, and posted them to the Mimecast blog. You can find them in these two posts, if you're interested:
