The Court rejects the appellant's argument that the Board should have given preclusive effect to a district court's Markman order, which had construed the claims in their favor in a prior litigation. The Court holds that issue preclusion is not warranted because the PTO was not a party to the earlier litigation, and as a result, did not have a "full and fair opportunity" to litigate the claim construction issues.
