A U.S. court has ruled that Samsung Electronics Co did not willfully infringe on some of Apple Inc's patents and denied a request by the U.S. firm to raise patent damages awarded to it in its legal dispute against the South Korean firm, a court ruling showed on Wednesday.

Apple has sought to raise the $1.05 billion damages awarded to it after a U.S. jury found in August that Samsung acted willfully when it violated several of Apple's patents.

That could form a basis for to triple the damages tab owed by Samsung.

In her series of rulings filed late on Tuesday U.S. time, U.S. District Court Judge Lucy Koh also denied Samsung's request for a new trial. Samsung has said a major patent verdict in favor of Apple should be overturned.
