This suit is an expansion of accusations made by Samsung last year against Apple when the former accused the Cupertino based firm of infringing on five Samsung patents relating to how data is transmitted by mobile devices. That suit was filed by Samsung in response to one filed by Apple in the U.S. accusing the Korean based firm of copying "the look and feel" of Apple devices.
The latest suit was filed Tuesday in Seoul Central District Court and was announced Wednesday by Samsung. The timing of the lawsuit and the announcement is certainly curious considering that later today, Apple is expected to introduce its third-generation tablet, the Apple iPad HD. Surely Samsung is trying to steal a bit of Apple's thunder prior to the iPad HD announcement. Both the Apple iPhone 4S and the Apple iPad are mentioned in the filing for the suit.
