"[Samsung has] made four more claims: two are standard-related patents and the other two are utility patents. And a court said it would make these claims separate from the April lawsuit," the spokesperson said.

Samsung has had some success against Apple, including winning the right to sell its Galaxy tablets in Australia in the last few shopping weeks before Christmas, but has lost out in its attempts to get bans on Apple products approved by the courts.

Apple has fought hard to get the Samsung Galaxy devices banned, and last week Samsung thanked Apple for its efforts, explaining that it had given the company a consumer profile that its marketing efforts could never have achieved.

Other patent lawsuit results are pending.
