Last week the Federal Circuit decided the case of Santarus, Inc. v. Par Pharmaceutical, Inc., which dealt with whether a drug covered by an Abbreviated New Drug Application (ANDA) infringed the patents owned by that patent owner relative to the proton pump inhibitors (PPI) product omeprazole. The big issue in the case is what might at first glance seem to be a rather innocuous statement relative to the support necessary in a patent specification for a negative claim limitation. But after reading the Newman dissent (which joins in the other aspects of the Court’s decision) it starts to become clear that this could be a much larger issue of significant consequence.
