The Federal Circuit affirmed the liability rulings but vacated and remanded the district court's denial of Samsung's motion to limit damages for failure to mark. Samsung moved the district court to limit Rembrandt's potential damages award because Rembrandt licensed its patent to Zhone Technologies, Inc., which sold unmarked products embodying asserted claim 40, the only claim Samsung alleged the unmarked products embodied. Rembrandt should have, but did not, require Zhone to mark its products.
