See, this system bears an uncanny resemblance to Klipsch’s very well-reviewed Energy Take Classic 5.1 system–which goes for $399. Now, CNET is reporting that on March 15, Klipsch and its subsidiary, Audio Products International, filed a lawsuit against Monoprice in federal court in the Southern District of Indiana, accusing the retailer of patent infringement. Klipsch is specifically seeking to stop the sales of the Monoprice speaker system and to receive triple the court-determined damages. Monoprice CEO Ajay Kumar has previously said the company “never purposely” sells products that infringe on another company’s patents.
