Executive Summary
The U.S. Court of Appeals for the Federal Circuit reversed a lower court's judgment invalidating Teva's headache-related patents, reinstating a jury verdict that Eli Lilly willfully infringed the patents. This strengthens Teva's IP position and may lead to damages or licensing revenue.
