British judges say Apple needs to apologize once more for falsely claiming that South Korea's Samsung copied its iPad, the latest embarrassing episode in the tech rivals' world-spanning patent battle.

Apple Inc. was ordered to print an apology on its website after British judges repeatedly rejected its claim that . ripped off its designs when creating its own , the Galaxy Tab.

Apple did post an apology, but judges at London's High Court ruled Thursday that it didn't go far enough and ordered a new one posted to its site within 48 hours.

Samsung and Apple are locked in a series of international lawsuits over alleged copyright violations, including a California case which saddled Samsung with a $1 billion fine for copying Apple's design.
