Case Overview
The case of Bausch Health Ireland Ltd. v. Mylan Labs. Ltd., filed in the District of New Jersey (Case No. 2:21-cv-10403-SRC-JSA), involves a patent infringement dispute under the Hatch-Waxman Act. The litigation centers around Mylan's attempt to market a generic version of Bausch Health's drug Trulance® (plecanatide), which is protected by several U.S. patents[1][2][4].
Background and Context
Under the Hatch-Waxman Act, a generic drug applicant must submit an Abbreviated New Drug Application (ANDA) to the FDA, which includes a certification that the patents associated with the brand-name drug are either invalid or will not be infringed by the manufacture, use, or sale of the new drug. Mylan filed such an ANDA for its plecanatide oral tablets, prompting Bausch Health to initiate litigation alleging patent infringement[4].
Key Issues and Arguments
Venue and Jurisdiction
A significant aspect of the case involved a dispute over the proper venue for the litigation. Mylan argued that the ANDA was prepared and electronically submitted by Mylan Pharmaceuticals Inc. (MPI) from West Virginia, and thus, the venue was proper only in the Northern District of West Virginia. Bausch Health countered that various Mylan entities, including Mylan Inc., Mylan API, Mylan Laboratories Ltd. (MLL), and Viatris Inc., were collectively involved in the development and would benefit from the ANDA, suggesting that the venue should be in New Jersey. The court ultimately granted Mylan's motion in part, denied Bausch's cross-motion, and transferred the case to the Northern District of West Virginia[1][2].
Corporate Separateness and Piercing the Corporate Veil
Bausch Health argued that the Mylan entities were essentially a single entity and should be treated as such, suggesting that the corporate veil should be pierced. However, the court upheld the principle of corporate separateness, finding no evidence to support the claim that the defendants were mere alter egos or that there were allegations of fraud or injustice that would justify piercing the corporate veil[1][2].
Role of Mylan Entities in ANDA Preparation
Bausch Health claimed that Mylan API, MLL, and Agila Specialties Inc. (Agila) were involved in the preparation of the ANDA due to their roles in manufacturing the active pharmaceutical ingredient (API), testing, and communicating with the FDA. However, the court rejected these arguments, stating that these activities did not constitute participation in the ANDA submission process as required under the Hatch-Waxman provisions[1][2].
Court Rulings and Decisions
Transfer of Venue
The court ruled that the venue was improper in New Jersey and transferred the case to the Northern District of West Virginia. This decision was based on the finding that MPI alone prepared and submitted the ANDA from West Virginia, and other Mylan entities did not have a regular and established place of business in New Jersey[1][2].
Dismissal of Declaratory-Judgment Claim
The court also dismissed Bausch Health's declaratory-judgment claim, as any relief sought would be duplicative of that available under the Hatch-Waxman provisions[1].
Motion for Judgment on the Pleadings
In a subsequent development, the district court in the Northern District of West Virginia denied Bausch Health's motion for judgment on the pleadings regarding Mylan's infringement of the patents-in-suit. The court held that Mylan was not limited to the invalidity and non-infringement theories raised in their Paragraph IV notice letter, citing Federal Circuit case law that such requirements cannot be enforced by a private party in a patent infringement action[4].

The court's decision underscores that a generic applicant's defenses in a Hatch-Waxman litigation are not strictly limited to the theories presented in the Paragraph IV notice letter[4].
Corporate Structure and Liability

This protects the integrity of corporate structures and ensures that each entity is held accountable only for its direct actions[1][2].
