SAN FRANCISCO—South Korea's Samsung Electronics Co. Ltd. Tuesday (June 28) filed a complaint with the U.S. International Trade Commission (ITC) requesting an investigation of alleged patent infringement by Apple Inc. and presumably seeking a ban on the importation of Apple products into the U.S.
The Bloomberg news service reported Wednesday that Samsung also filed suit against Apple in U.S. federal court in Delaware, alleging that Apple infringed on Samsung's patents for technology used in iPhone, iPad and iPod products.
Apple and Samsung have traded patent infringement litigation in multiple venues for the past few months. Apple initially sued Samsung in April, claiming that Samsung copied the look and feel of Apple products with its own smartphone and media tablet offerings. Samsung countersued Apple a few days later.
Samsung is a long time supplier to Apple that has served as a chip foundry for Apple's processors and supplied the company with displays and other products. Earlier this week, rumors again circulated that Apple was preparing to replace Samsung as its chip foundry with foundry giant Taiwan Semiconductor Manufacturing Co. Ltd., presumably in relation to the patent infringement allegations.
Samsung's ITC complaint, addressed to ITC Secretary James Holbein, asks for an investigation of Apple under section 337 under the U.S. Tariff Act of 1930. The text of the complaint could not immediately be obtained.
Such complaints typically ask the ITC to bar the importation into the U.S. of products found to infringe the patents of the complainant. The ITC must still determine whether to investigate the complaint, and such investigations typically take more than a year.
