In the seemingly never ending patent wars, Samsung has announced that, last week, it filed a complaint against Ericsson to ban U.S. sales on some of Ericsson's products. This move comes a month after Ericsson sued Samsung in the U.S for patent infringement.

The company said in a statement that "we have sought to negotiate with Ericsson in good faith. However, Ericsson has proven unwilling to continue such negotiations by making unreasonable claims, which it is now trying to enforce in court."

These recent developments come after 2 years of failed negotiations, and licensing agreements. Twenty-four patent's are involved in the litigation. Ericsson said "the dispute concerns both Ericsson's patented technology that is essential to several telecommunications and networking standards used by Samsung's products as well as other of Ericsson's patented inventions that are frequently implemented in wireless and consumer electronics products."
