Apple Inc. hasn’t exactly been hurting for good news on the patent litigation front these days. But William Lee of Wilmer Cutler Pickering Hale and Dorr delivered another dollop on Sept. 4, less than three weeks after he helped produce the company’s $1.05 billion California trial win against Samsung Electronics Co.

The latest win for Lee and Apple came courtesy of the U.S. Court of Appeals for the Federal Circuit, which affirmed a lower court’s decision to toss a $208.5 million infringement verdict for Mirror Worlds LLC. The ruling is the latest, and likely final, blow for Mirror Worlds in its long-running case against Apple for allegedly copying a Yale University professor’s patented method of displaying documents on a computer screen.
