Patents

I get sick and tired of hearing patent threats, trolls, sueing of invalid patents, etc. These are forever clogging up tech. Examples include final certification(although certified draft is fine) of wifi N and CED(screen technology). I agree that software patents should be stopped and invalidated, and highly generic patents taken down. They have caused enough trouble as they are without asking for more. Please listen...(i could go on about dcma but i won't)
