Background
The litigation in question involves a patent infringement dispute between Forest Laboratories, LLC, and its affiliated companies, and Aurobindo Pharma Ltd. and its U.S. subsidiary, Aurobindo Pharma USA, Inc. This case was filed in the United States District Court for the District of Delaware and is identified as Civil Action No. 17-01210[1].
Parties Involved
- Plaintiffs: Forest Laboratories, LLC, Forest Laboratories Holdings, Ltd., Allergan USA, Inc., and Ironwood Pharmaceuticals, Inc.
- Defendants: Aurobindo Pharma Ltd. and Aurobindo Pharma USA, Inc.
Subject Matter
The dispute centers around Aurobindo's submission of an Abbreviated New Drug Application (ANDA) to the U.S. Food and Drug Administration (FDA) for generic versions of Forest Laboratories' branded prescription drug product, Linzess®. Linzess® contains linaclotide as its active ingredient and is used for the treatment of irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC)[1].
Patent Infringement Claims
The plaintiffs alleged that Aurobindo's ANDA filing constituted an act of patent infringement. Specifically, Aurobindo's ANDA sought FDA approval for generic capsule products containing 145 μg and 290 μg of linaclotide, which allegedly infringed several patents held by the plaintiffs. These patents include the '036, '727, '947, '409, '526, and '553 patents[1].
Jurisdiction and Venue
The court has personal jurisdiction over the defendants because they have committed tortious acts of patent infringement that have caused foreseeable harm and injury to the plaintiffs in Delaware. Additionally, the defendants have plans to manufacture, distribute, market, and sell the generic products throughout the United States, including in the District of Delaware[1].
ANDA Filings and Amendments
Aurobindo initially filed the ANDA with allegations that certain patents were invalid or would not be infringed. However, Aurobindo later amended the ANDA to include new allegations regarding the invalidity or non-infringement of additional patents ('036, '727, '947, '409, '526, and '553 patents). The plaintiffs did not receive written notification of these amendments until July 28, 2017[1].
Legal Proceedings
The plaintiffs timely brought suit against Aurobindo for infringement of the '030 patent in November 2016. Following the amendment of the ANDA, the plaintiffs filed the current complaint to address the alleged infringement of the additional patents[1].
Analysis
This litigation highlights the complex and often contentious nature of pharmaceutical patent disputes. Here are some key points:
Strategic Importance of Patent Protection
For pharmaceutical companies, patents are crucial for protecting their intellectual property and maintaining market exclusivity. The plaintiffs' aggressive pursuit of patent infringement claims underscores the importance of these protections in the highly competitive pharmaceutical industry.
ANDA Filings and Patent Challenges
The process of filing ANDAs and challenging patents is a common pathway for generic drug manufacturers to enter the market. However, this process can lead to extensive litigation, as seen in this case, where the generic manufacturer's amendments to the ANDA triggered additional patent infringement claims.
Jurisdiction and Venue Considerations
The court's jurisdiction over the defendants is based on the defendants' activities within the state of Delaware, including their plans to sell the generic products in the state. This highlights the importance of jurisdictional considerations in patent litigation.
Conclusion
The litigation between Forest Laboratories, LLC, and Aurobindo Pharma Ltd. is a prime example of the intricate and often litigious landscape surrounding pharmaceutical patents.
