In this case, the United States Court of Appeals for the Federal Circuit considered whether the defendants' Abbreviated New Drug Applications (ANDAs) infringed two patents owned by the plaintiffs. The patents pertained to the use of the drug vortioxetine in the treatment of patients who had previously taken certain other antidepressant medications and had to cease or reduce use due to sexually related adverse events, and for the treatment of cognitive impairment. The defendants were seeking approval to market vortioxetine for the treatment of Major Depressive Disorder (MDD) in adults, a use not covered by the patents. The plaintiffs sought to block the defendants from marketing a generic version of the drug until after the expiration of the patents.
The court held that the defendants' ANDA filings did not infringe the plaintiffs' patents. The court found that the defendants' intended use of the drug, for the treatment of MDD in adults, did not infringe the patents which pertained to other specific uses of the drug.
Moreover, the court found no induced or contributory infringement. Regarding induced infringement, the court held that the defendants' proposed labels for the drug did not encourage, recommend, or promote an infringing use. Regarding contributory infringement, the court held that the defendants' sale of the drug would have substantial noninfringing uses, thus there would be no contributory infringement.
Additionally, the court rejected Lupin's cross-appeal, which challenged the district court's determination that Lupin infringed a patent concerning a process for manufacturing vortioxetine. The court affirmed the district court's construction of the term "reacting" in the patent and its determination of infringement.
