Samsung Broadens Patent Dispute Against Apple With U.S. Suit

Samsung Electronics Co., the second-largest maker of mobile phones, broadened its patent-infringement dispute with Apple Inc. by suing the iPhone creator in the U.S. a week after making claims in Asia and Europe.

Apple is infringing 10 patents related to mobile phones, Samsung said in an April 27 lawsuit in federal court in San Jose, California. The Suwon, South Korea-based company, which sells the Galaxy smartphone and tablet, claims Apple is using Samsung’s inventions without paying.
