The Genesis of the Patent Infringement Lawsuit
In the complex world of pharmaceutical patents, legal battles are not uncommon. One such significant case is the patent infringement lawsuit filed by Mitsubishi Tanabe Pharma Corporation against Aurobindo Pharma USA Inc. This legal dispute, filed in the United States District Court for the District of New Jersey, has garnered attention in the pharmaceutical industry due to its potential implications for drug patents and market competition.
Background of the Case
The case, officially titled MITSUBISHI TANABE PHARMA CORPORATION v. AUROBINDO PHARMA USA INC. (Civil No. 17-5005), revolves around alleged patent infringement. Mitsubishi Tanabe Pharma Corporation, a Japanese pharmaceutical company, claims that Aurobindo Pharma USA Inc., an Indian multinational pharmaceutical company, infringed on its patents related to certain drug formulations.
The Crux of the Dispute
At the heart of this legal battle is the allegation that Aurobindo Pharma USA Inc. filed Abbreviated New Drug Applications (ANDAs) to market generic versions of Mitsubishi Tanabe's patented drugs. This move, according to the plaintiffs, constitutes a direct infringement of their intellectual property rights.
Key Players in the Litigation
The Plaintiffs: Mitsubishi Tanabe Pharma Corporation
Mitsubishi Tanabe Pharma Corporation, a subsidiary of Mitsubishi Chemical Holdings Corporation, is a global pharmaceutical company known for its innovative drug development. With a rich history dating back to 1678, the company has been at the forefront of medical advancements, particularly in the areas of diabetes, kidney disease, and central nervous system disorders.
The Defendants: Aurobindo Pharma USA Inc.
Aurobindo Pharma USA Inc., a subsidiary of Aurobindo Pharma Limited, is a prominent player in the generic pharmaceutical market. The company has made significant strides in developing, manufacturing, and marketing a wide range of pharmaceutical products across various therapeutic categories.
The Legal Landscape: Patent Infringement in the Pharmaceutical Industry
Patent infringement cases in the pharmaceutical sector are not uncommon. These legal battles often stem from the tension between brand-name drug manufacturers seeking to protect their investments in research and development, and generic drug companies aiming to bring more affordable alternatives to the market.
The Role of Abbreviated New Drug Applications (ANDAs)
ANDAs play a crucial role in these disputes. Generic drug manufacturers file ANDAs to gain FDA approval for marketing generic versions of brand-name drugs. However, this process often leads to litigation when the original patent holders believe their intellectual property rights are being infringed upon.
"The Hatch-Waxman Act has created a system that produces patent litigation as a normal part of the drug approval process," notes Professor Robin Feldman of the University of California Hastings College of the Law[1].
The Litigation Process: A Step-by-Step Analysis
Filing of the Lawsuit
The case was initiated when Mitsubishi Tanabe Pharma Corporation filed a complaint against Aurobindo Pharma USA Inc. in the United States District Court for the District of New Jersey. The choice of venue is significant, as New Jersey is known for handling numerous pharmaceutical patent cases due to the high concentration of pharmaceutical companies in the state.
The Discovery Phase
Following the initial filing, the case entered the discovery phase. During this period, both parties exchange relevant information and evidence. In patent infringement cases, this often involves detailed technical information about drug formulations and manufacturing processes.
Motion Practice
Throughout the litigation, various motions were filed by both parties. One notable motion was the defendants' motion to seal certain portions of the transcript from an oral argument held on May 18, 2020. This motion, which was granted, highlights the sensitive nature of the information involved in pharmaceutical patent litigation.
The Court's Decision on Sealing
The court's decision to grant the motion to seal underscores the importance of protecting proprietary information in patent cases. As stated in the court order:
"The Court finds defendants may suffer serious injury if a competitor possessed the information they seek to seal. The Court agrees that if the information is published it may be used by defendants' competitors to develop competing products."[6]
Expert Testimony and Reports
Expert testimony plays a crucial role in patent infringement cases. Both parties typically engage experts to provide opinions on technical aspects of the patents and alleged infringement. In this case, there was a motion to strike plaintiffs' expert reports, indicating the contentious nature of the expert testimony.
Key Legal Issues in the Case
Patent Validity
One of the primary issues in patent infringement cases is the validity of the patents in question. Defendants often challenge the validity of the plaintiff's patents as part of their defense strategy.
Infringement Analysis
The court must determine whether the defendants' products or processes infringe on the plaintiffs' patents. This involves a detailed comparison of the patented invention and the allegedly infringing product or process.
Damages and Remedies
If infringement is found, the court must determine appropriate damages or remedies. This could include monetary compensation for the patent holder and injunctions against further infringement.
Implications for the Pharmaceutical Industry
Impact on Drug Pricing and Availability
The outcome of this case could have significant implications for drug pricing and availability. If the plaintiffs prevail, it could delay the entry of generic versions of their drugs into the market, potentially affecting drug prices and accessibility.
Innovation and Patent Protection
The case also highlights the ongoing debate in the pharmaceutical industry about balancing innovation incentives through patent protection with the need for affordable generic drugs.

The FDA plays a crucial role in these disputes through its oversight of the ANDA process and its implementation of the Hatch-Waxman Act.
United States Patent and Trademark Office (USPTO)
The USPTO's role in granting and reviewing patents is fundamental to understanding the basis of pharmaceutical patent litigation.
Future Outlook: Potential Outcomes and Industry Impact
Possible Settlement Scenarios
Many pharmaceutical patent cases end in settlements. A settlement in this case could involve licensing agreements or other arrangements that allow both parties to benefit.
Potential Court Decisions
If the case proceeds to a final court decision, it could set important precedents for future pharmaceutical patent litigation, particularly regarding the interpretation of patent claims and the assessment of infringement in the context of generic drug development.
Lessons for Pharmaceutical Companies
Importance of Robust Patent Strategies
This case underscores the importance of comprehensive patent strategies for pharmaceutical companies, including both innovator companies and generic manufacturers.

FAQs
-
Q: What is an Abbreviated New Drug Application (ANDA)?
A: An ANDA is an application for a U.S. generic drug approval for an existing licensed medication or approved drug. It's "abbreviated" because it doesn't require the applicant to conduct clinical trials and relies on the safety and efficacy data of the original drug.
-
Q: How does patent litigation affect drug prices?
A: Patent litigation can delay the entry of generic drugs into the market, potentially keeping drug prices higher for a longer period. However, it also protects the investments of innovator companies, which can encourage future drug development.
-
Q: What is the Hatch-Waxman Act?
A: The Hatch-Waxman Act, officially known as the Drug Price Competition and Patent Term Restoration Act of 1984, is a U.S. federal law that established the modern system of generic drug approval and patent litigation in the pharmaceutical industry.
-
Q: How long do pharmaceutical patents typically last?
A: In the United States, pharmaceutical patents generally last for 20 years from the date of filing. However, the effective patent life is often shorter due to the time required for clinical trials and regulatory approval.
-
Q: What happens if a court finds patent infringement in a pharmaceutical case?
A: If infringement is found, the court may award damages to the patent holder and issue an injunction preventing further infringement. This could prevent the generic manufacturer from selling their product until the patent expires.
