SEOUL, South Korea - Samsung says it will file court injunctions in France and Italy seeking to block the sale of Apple's latest iPhone amid an intensifying patent fight between the smartphone giants.

Samsung Electronics Co. said Wednesday it plans to file preliminary injunctions in Paris and Milan asking that courts block Apple's iPhone 4S from being sold in France and Italy, alleging patent infringement of wireless telecommunications technology.

The move comes one day after Apple Inc. unveiled the iPhone 4S in the United States.

Seoul-based Apple spokesman Steve Park, speaking by phone from Japan, declined to comment.

Apple took Samsung to court in April claiming its Galaxy line of smartphones and tablets copy the iPhone and iPad.
