Apple sent a shock wave through the technology community when it announced it was suing Samsung — a company that supplies the Cupertino-based iPhone maker with over $5 billion worth of components each year. Now that the gloves are officially off, Samsung is doing a little legal posturing of its own, this time Stateside. Reuters is reporting that Samsung Electronics has filed a lawsuit against Apple, claiming that the company has violated no fewer than ten patents held by the Korean company. “Apple copied many of Samsung’s innovations, according to Samsung’s U.S. lawsuit,” reads the report. “For instance, one of the patents Samsung accuses Apple of violating involves the ability for mobile phones to display the time.” The case will be heard at a date to be named in U.S. District Court, Norther District of California. Samsung has already filed complaints against Apple in Japan, Korea, and Germany.
