In the complex world of pharmaceutical litigation, the case of Valeant Pharmaceuticals International Inc. v. Par Sterile Products, LLC (Case No. 2:17-cv-06449) stands out as a significant legal battle. This article delves into the intricacies of this lawsuit, exploring its background, key issues, and potential implications for the pharmaceutical industry.
The Genesis of the Lawsuit
The legal dispute between Valeant Pharmaceuticals (now known as Bausch Health Companies Inc.) and Par Sterile Products began in 2017 when Valeant filed a lawsuit in the United States District Court for the District of New Jersey. The core of the conflict revolved around Par's alleged infringement of patents related to Valeant's drug Relistor®, a medication used to treat opioid-induced constipation.
Understanding Relistor® and Its Importance
Relistor® (methylnaltrexone bromide) is a prescription medication that plays a crucial role in managing side effects associated with opioid use. Its significance in the pharmaceutical market made it a valuable asset for Valeant, and consequently, a target for generic competition.
The Legal Landscape
The lawsuit filed by Valeant accused Par Sterile Products of infringing on six patents related to Relistor®. This legal action was taken under the provisions of the Hatch-Waxman Act, which governs the approval process for generic drugs in the United States.
The Hatch-Waxman Act: A Brief Overview
The Hatch-Waxman Act, formally known as the Drug Price Competition and Patent Term Restoration Act of 1984, aims to balance innovation in the pharmaceutical industry with the need for affordable generic drugs. It provides a framework for generic drug manufacturers to challenge patents held by brand-name drug companies.
Key Players in the Litigation
Valeant Pharmaceuticals (Plaintiff)
Valeant Pharmaceuticals, now operating as Bausch Health Companies Inc., is a multinational specialty pharmaceutical company. Known for its growth-by-acquisition strategy, Valeant has been involved in numerous high-profile legal cases and controversies over the years.
Par Sterile Products (Defendant)
Par Sterile Products, LLC, a subsidiary of Endo International plc, is a leading manufacturer of generic and branded pharmaceutical products. The company has a history of challenging patents to bring generic alternatives to market.
The Crux of the Dispute
At the heart of the litigation was Par's attempt to introduce a generic version of Relistor® before the expiration of Valeant's patents. This move, typical in the pharmaceutical industry, triggered Valeant's lawsuit to protect its intellectual property and market exclusivity.
Patent Infringement Claims
Valeant alleged that Par's proposed generic product would infringe on six of its patents related to Relistor®. These patents covered various aspects of the drug, including its formulation and methods of use.
Legal Strategies and Arguments
Both parties employed sophisticated legal strategies to advance their positions. Valeant sought to enforce its patent rights and prevent Par from entering the market with a generic version of Relistor®. Par, on the other hand, likely challenged the validity of Valeant's patents or argued non-infringement.
The Role of Expert Witnesses
In pharmaceutical patent litigation, expert witnesses often play a crucial role. These experts may include scientists, pharmacologists, and patent attorneys who can provide specialized knowledge to support each party's claims.
The Settlement: A Turning Point
In a significant development, the case was resolved through a settlement between Valeant and Par. While the specific terms of the settlement were not fully disclosed in the available public records, such agreements often involve licensing arrangements or agreed-upon dates for generic market entry.

The strategies employed by both parties and the court's handling of the case could inform similar litigation in the future.
The Role of the FDA
Although not directly involved in the litigation, the U.S. Food and Drug Administration (FDA) plays a crucial role in the broader context of such disputes. The FDA's policies and decisions regarding generic drug approvals can significantly impact the outcomes of patent litigation.
Financial Implications for the Companies Involved
Patent litigation and settlements can have substantial financial implications for pharmaceutical companies. For Valeant, protecting Relistor®'s market exclusivity was likely crucial for maintaining revenue streams. For Par, the potential to enter the market with a generic version represented a significant business opportunity.

The Rise of Inter Partes Reviews
In recent years, there has been an increase in the use of Inter Partes Reviews (IPRs) to challenge pharmaceutical patents. While not directly related to this case, the availability of IPRs has added another layer of complexity to pharmaceutical patent disputes.
Ethical Considerations in Pharmaceutical Litigation
Cases like Valeant v. Par raise important ethical questions about the balance between profit motives and public health interests. Critics argue that prolonged patent protection can keep drug prices high, while defenders contend that it's necessary to recoup research and development costs.
