I am against patents in general, and especially against software patents. I wasted a lot of time from ~1990 to ~2000 with RSA alternatives, and then there was the whole Chaum and Brands patent mess which was another bottleneck for anonymous cryptographic token electronic cash (think bitcoin but anonymous, and even better).

I am really kind of sad that I'll be getting some for my new company; it's a waste of $100k, time, etc., but it is the prudent thing to do.
