Apple has filed another lawsuit against Samsung Electronics with an American court, and the two law firms handling Apple's lawsuits have recently hired some 73 Korean-American lawyers to handle the litigation. That suggests the patent war between the two electronics giants is far from over.

Apple filed the new lawsuit with the Northern District Court of California in San Jose last Friday, saying preparations for litigation hit a snag because Samsung failed to submit evidence properly.

Samsung had submitted only a few parts of source codes for the Galaxy smartphones and Galaxy Tab tablet PCs, violating a court order to submit them in full, Apple claims.

The two law firms -- Morrison & Foerster and WilmerHale -- have hired 73 Korean-literate staff, apparently to review Korean-language documents related to patent litigations against the Korean firm.

Earlier, Apple had asked another American court for an injunction to ban three Galaxy smartphone models and the Galaxy Tab 10.1 tablet PC in the American market. But the court rejected the request last December. A total of 31 patent lawsuits have been filed by either Apple or Samsung against the other in a total of nine countries.
