that is already in a corner where punches are being dealt: Yahoo.

NTP alleges that Yahoo infringes patents it owns, more specifically covering wireless email technology and radio frequency antenna design.

About half of the US patents held by NTP were originally assigned to a company called Telefind, which was partly owned by the late inventor Thomas J. Campana. The company is now out of business, and NTP apparently decided that suing the world for infringement of patents it acquired was a much better business model than actually building something useful.

That said, Yahoo better be prepared to defend itself vigorously – five of the patents in-suit were subject of earlier, intensive patent litigation between NTP and RIM. The Blackberry maker settled the lawsuit in March 2006 for a whopping $612.5 million.

The complaint is embedded below.
