NEW YORK (
) -- A South Korean company has sued
Procter & Gamble
for two patent violations over one of its adhesive teeth whitening strips.
LG Household & Health Care
says that P&G's Crest Whitestrips Advanced Seal has been using technology owned by LG. Its two U.S. patents were issued in 2004.
The lawsuit was filed this week in a Delaware district court.
LG has asked a federal court to stop P&G from continuing with the alleged patent infringements and seeks an unspecified amount in damages.
P&G says that since 2001, Crest Whitestrips has been the winner of multiple awards and is used by more than 50 million people. Crest Whitestrips Advanced Seal made its market debut in February. It sells for $45 and contains 14 doses of whitening strips.
P&G stock has added 0.3% to $62.40 in afternoon trading. Rival
Johnson & Johnson
has advanced 0.8% to $64.90. Meanwhile,
has risen 1% to $64.70 and
has moved one up 0.6% to $83.
