Judge Andrews issues post-trial ANDA opinion in favor of Plaintiffs

In Impax Labs., Inc., et al. v. Lannett Holdings Inc., et al., C.A. No. 14-984-RGA, 14-999-RGA (D. Del. Mar. 29, 2017), Judge Richard G. Andrews issued a post-trial decision regarding Plaintiffs’ standing to bring suit and Defendants’ allegations of invalidity of Plaintiffs’ patents.

As to standing, Defendants argued that the “exact ownership arrangement of the patents” was not clear. Id. at 3. The Court examined a chain of ownership where the patents-in-suit were not always specifically called out as being part of various transfers. See id. at 5-6. But the Court concluded that there was “no reason to believe” there was any gap in ownership, crediting the statements of a declaration submitted by Plaintiffs post-trial and accepted by the Court (see id. at 4-5). Id. at 6. While, based on the documents at issue, it appeared possible that one of the named Plaintiffs no longer had an ownership interest in the patents, that did not impact the others’ standing to bring suit, and Defendants had only moved to dismiss “in toto for lack of standing.” Id. at 7.

As to Defendants’ anticipation and obviousness arguments, the Court found that they had not met their burden to show invalidity, and that Plaintiffs had presented evidence of secondary considerations of non-obviousness. See id. at 16-35.
