What is at the heart of the GSK skinny-label standoff at the CAFC?

I previously blogged about the surprising case, GlaxoKlineSmith v. Teva (GSK), where the Federal Circuit held that a generic pharmaceutical company can, under the right circumstances, be liable for inducing infringement of a method-of-use pharmaceutical patent despite carving out the patented indication from its label. The decision at first spooked the generic pharmaceutical industry, but was then followed by two additional opinions—one related to a panel rehearing, followed by another one, which issued on February 11, 2022, denying a hearing en banc, which included a fiery dissent. These decisions show clear disagreements among the Judges at the Federal Circuit. What is at the heart of this dispute?

Will Amarin’s new cardiovascular patent lawsuit against Hikma keep out generic sales?

The battle continues. We previously wrote about the Federal Circuit’s decision in the case (GlaxoSmithKline v. Teva) and how that case may offer Amarin another chance to bar generics from the market for Vascepa®. Sure enough, on November 30, Amarin filed suit against Hikma asserting three patents covering use of EPA to treat cardiovascular events. What are the takeaways from this suit?

Can Amarin benefit from the GSK v. Teva decision regarding induced infringement for off-label sales?

Just when you think the Amarin saga to keep out generic competition is over, something else happens. In the latest development, the Federal Circuit issued a precedential decision in an unrelated case (GlaxoSmithKline v. Teva) that suggests that a generic could potentially be liable for inducing infringement of a patented indication, even though that indication has been carved out of the generic’s label. Will this decision benefit Amarin?

Amarin: Did the district court commit error by misinterpreting Kurabayashi?

The post mortem of the district court’s decision invalidating Amarin’s ($AMRN) Marine patents continues. We received questions regarding a finding of fact related to the prior art reference, Kurabayashi. The Honorable Miranda M. Du from the District of Nevada found that Kurabayashi was not considered during prosecution of the patents and that Kurabayashi suggested that pure EPA would reduce Apo-B. Are these findings accurate? If not, are they a basis to reverse Judge Du’s decision on appeal?

Amarin: Did the court commit a procedural error when invalidating the Vascepa patents?

In the wake of the Nevada district court’s opinion on March 30, which invalidated Amarin’s patents for the Marine indication, we have received questions regarding whether the court committed a procedural error that may justify a reversal on appeal.

Can Amarin win on appeal in the Vascepa patent litigation?

Amarin ($AMRN) has lost its trial against Hikma and Dr. Reddy’s. On March 30, the Honorable Miranda M. Du from the United States District Court for the District of Nevada issued a bench order following a multi-day trial in January. Judge Du held that although Amarin had proven that the generics would induce infringement of the asserted patents by selling their prospective generic versions of Vacepa®, all of the patents were nonetheless invalid as obvious. As a result, Judge Du denied an injunction against Hikma and Dr. Reddy’s for selling generic versions of Vascepa®. What happens now?
