Opinion Summary – Salix Pharmaceuticals, Ltd. v. Norwich Pharmaceuticals Inc.

Last month the Federal Circuit issued its opinion in Salix Pharmaceuticals, Ltd. v. Norwich Pharmaceuticals Inc., a patent case that attracted an amicus brief. In this case, the Federal Circuit reviewed a judgment by the District of Delaware, which held that Norwich infringed certain patent claims but that other claims were invalid for obviousness. After Norwich amended its Abbreviated New Drug Application to remove the infringing indication, Norwich sought to modify the judgment, contending the amendment negated any possible infringement. The district court, however, denied its motion. The Federal Circuit, in an opinion authored by Judge Lourie that was joined by Judge Chen, affirmed the judgment of the district court. Judge Cunningham, however, filed a dissenting opinion. This is our opinion summary.

Opinions & Orders – April 11, 2024

This morning, the Federal Circuit released one precedential opinion, two nonprecedential opinions, and six nonprecedential orders. The precedential opinion, which attracted two amicus briefs, addresses an appeal from a final judgment of a district court holding certain patent claims invalid as obvious. Judge Cunningham filed an opinion dissenting in part. One of the nonprecedential opinions affirms four final written decisions of the Patent Trial and Appeal Board, determining all claims are unpatentable over asserted prior art. The other nonprecedential opinion affirms a decision of the Merit Systems Protections Board. Two of the nonprecedential orders transfer appeals to other United States appellate courts. Four of the nonprecedential orders are dismissals. Here are the introductions to the opinions, selected text from the transfer orders, and links to the dismissals.

Argument Recap – Salix Pharmaceuticals, Ltd. v. Norwich Pharmaceuticals Inc.

Earlier this month, the Federal Circuit heard oral argument in Salix Pharmaceuticals, Ltd. v. Norwich Pharmaceuticals Inc., a patent case we are following because it attracted amicus briefs. In this case, the Federal Circuit is reviewing a judgment of the District of Delaware ruling on patent infringement and invalidity claims. The district court held that, if approved, Norwich’s Abbreviated New Drug Application would induce infringement of certain Salix patent claims (the “HE,” “IBS-D,” and “Polymorph” claims). Additionally, the court held that, while Salix’s HE claims are nonobvious and therefore not invalid, the asserted Polymorph and IBS-D claims are invalid as obvious. Both parties appealed the district court’s judgment. This is our argument recap.
