Nature of the Action
This case is an action for patent infringement under the Food and Drug Laws and Patent Laws of the United States, specifically Titles 21 and 35 of the United States Code.

Patent-in-Suit
The central issue revolves around the infringement of U.S. Patent '323, which is associated with the drug empagliflozin. Boehringer Ingelheim alleges that Lupin's Abbreviated New Drug Applications (ANDAs) for empagliflozin, empagliflozin/linagliptin, and empagliflozin/metformin extended-release products infringe on this patent. The plaintiffs claim that Lupin's products are especially made or adapted for use in infringing at least one of the claims of the '323 patent, either literally or under the doctrine of equivalents[1][3][4].
Accused Products
The litigation involves several generic drug products developed by Lupin:
- Empagliflozin ANDA Product: This is a generic version of Boehringer Ingelheim's Jardiance.
- Empagliflozin/Linagliptin ANDA Product: A combination drug that includes empagliflozin and linagliptin, similar to Boehringer Ingelheim's Glyxambi.
- Empagliflozin/Metformin Extended-Release ANDA Product: A combination drug that includes empagliflozin and metformin extended-release, similar to Boehringer Ingelheim's Synjardy XR[1][3][4].

Complaint and Allegations
Boehringer Ingelheim alleges that Lupin had knowledge of the '323 patent and that its promotional activities and package inserts for the accused products indicate an intent to aid and abet another’s direct infringement of the patent. The plaintiffs also claim that Lupin's actions would actively induce infringement of the '323 patent[1].
Consolidation of Cases
In April 2022, Judge Colm F. Connolly ordered the consolidation of this case with another related case (Civil Action No. 20-1153 CFC) for all purposes, directing all future filings to be made in the lead case[3].

Potential Consequences
Boehringer Ingelheim seeks an injunction to prevent Lupin from infringing the '323 patent, arguing that they will be substantially and irreparably harmed if Lupin is not enjoined. The case is also designated as an exceptional case under 35 U.S.C. § 285, which could warrant reimbursement of Boehringer’s reasonable attorney fees[1][3][4].
