SAN FRANCISCO Apple asked a U.S. court to issue a preliminary injunction against Samsung on four patents in a dispute between the two companies, according to a court filing.
The iPhone and iPad maker also asked for a faster trial schedule to resolve all of its intellectual property claims against Samsung.
The legal battle between the two tech giants has been building since April, when Apple sued Samsung in a California federal court. Apple claims the South Korean firm's Galaxy line of mobile phones and tablets "slavishly" copies the iPhone and iPad.
Apple was Samsung's second-biggest customer last year after Sony, accounting for about $5.7 billion of sales to Samsung mainly by purchasing semiconductors, according to Samsung's annual report.
Samsung then countersued in California, and earlier this week asked the U.S. International Trade Commission to impose an import ban on Apple's iPhones and iPads.
In the latest salvo, Apple asked the U.S. District Court in San Jose, Calif. on Friday to issue a preliminary injunction that would prevent Samsung from infringing three Apple design patents, and one utility patent, according to a court filing.
If granted, the preliminary injunction would apply to Samsung products including the Galaxy S 4G smartphone and the Galaxy Tab 10.1 tablet computer, Apple's court filing says.
"We're going to actively protect and defend our intellectual property and our ability to provide consumers with innovative technology," Samsung spokesman Kim Titus said.
Apple also asked that a trial on all of its claims be held in February 2012.
An Apple representative could not immediately be reached for comment.
Samsung's Galaxy products use Google's Android operating system, which directly competes with Apple's mobile software.
The case in U.S. District Court, Northern District of California is Apple Inc v. Samsung Electronics Co Ltd et al, 11-1846.
