The case was a patent dispute between i4i Ltd. Partnership and Microsoft: i4i charged that Microsoft Word infringed on i4i's patent; Microsoft argued that the clear and convincing evidence standard applied by the Federal Circuit was inappropriate and that a preponderance of the evidence standard should be applied. The Court rejected Microsoft's position.[2]
