Twitter sued for patent infringement

Twitter has become so popular that it's the forum that Paul Abdul informs us she won't becoming back to "American Idol" next season and the digital hub that strikes fear in the hearts of ESPN executives.

Popularity breeds jealousy, and almost every successful digital media company has been sued for patent infringement. OK, maybe that's an exaggeration, but it's time for Twitter's day in court.

Texas-based TechRadium has filed a lawsuit in Houston district court against Twitter for patent infringement. Here's the complaint.

TechRadium says it develops, sells, and services mass notification systems and alleges Twitter is violating its IRIS product patent. Here's an abstract on patent #7130389:

A digital notification and response system utilizes an administrator interface to transmit a message from an administrator to a user contact device. The system comprises a dynamic information database that includes user contact data, priority information, and response data. The administrator initiates distribution of the message based upon grouping information, priority information, and the priority order. (Read the rest here.)

TechRadium also says the infringement is "willful," which would increase damages if it is successful in court.
