In a case concerning two divisional patents derived from the same parent application relating to ‘transcatheter heart valves’ or THVs, which can be introduced via a blood vessel, rather than through open heart surgery, the Court held one patent invalid for lack of inventive step, though had it been valid it would have been infringed. The second patent was held valid and infringed.
