Samsung has asked the U.S. International Trade Commission to ban imports of Apple's products including iPhones, iPads and iPods.
In a filing on Tuesday, Samsung accused Apple's iPhones, iPads and iPods of infringing five of its patents involving telecommunications standards and user interface inventions, Reuters reported.
On Wednesday, Samsung filed another patent lawsuit against Apple in Delaware federal court.
The two consumer electronics giants are in a legal battle for the last few months. In April, Samsung was sued by Apple in a California federal court. In the lawsuit, Apple charged the South Korean company of copying the iPhone and iPad for its Galaxy line of mobile phones and tablets.
Being one of the fastest-growing smartphone makers, Samsung has emerged as Apple's strongest rival in the growing tablet market.
Samsung manufactures microchips for Apple's gadgets, a business that brought in about $5.7 billion in revenue for the South Korean company last year, according to Reuters.
