Argument Recap – Hikma Pharmaceuticals USA Inc. v. Amarin Pharma, Inc.
Late last month, the Supreme Court heard oral argument in Hikma Pharmaceuticals USA Inc. v. Amarin Pharma, Inc., a case originally decided by the Federal Circuit. The Supreme Court granted review to consider the following two questions:
- “When a generic drug label fully carves out a patented use, are allegations that the generic drugmaker calls its product a ‘generic version’ and cites public information about the branded drug (e.g., sales) enough to plead induced infringement of the patented use?”
- “Does a complaint state a claim for induced infringement of a patented method if it does not allege any instruction or other statement by the defendant that encourages, or even mentions, the patented use?”
This is our argument recap.
