The Hatch-Waxman Act provides a safe harbor that allows importation of an FDA-regulated article that would otherwise be deemed a case of patent infringement so long as the importation is for purposes reasonably related to obtaining regulatory approval. Edwards Lifesciences Corp. sued Meril Life Sciences Pvt Ltd. for importation of heart valves in a manner that Edwards argued was infringement under Hatch-Waxman, but while the Federal Circuit ruled 2-1 against Edwards, the dissenting opinion recommended an appeal to a full 12-judge panel that could reverse this outcome.

Having failed in their efforts to get the U.S. NIH to march in on Xtandi’s patents under the Bayh-Dole Act because of price, Knowledge Ecology International and two other advocacy groups are now asking the Centers for Medicare & Medicaid Services (CMS) to do what the NIH refused to do. But rather than pressing for a march-in, which can be a lengthy process, the groups are pushing for CMS to use other statutory tools to clear the way for Xtandi (enzalutamide) generics to launch in the U.S. before Astellas Pharma Inc.’s three remaining patents for the prostate cancer drug expire in 2026 and 2027.
