Case Overview
The Parties

Global generic pharmaceutical manufacturer based in India, whose U.S. subsidiary filed ANDA No. 211107 for generic macitentan.

The Verdict & Legal Analysis
Outcome
The case resolved via **Consent Judgment** in a remarkably swift 30-day period. Torrent Pharmaceuticals expressly **admitted the validity and enforceability** of U.S. Patent No. 7,094,781 and conceded that its proposed generic macitentan product would infringe prior to patent expiration. A **permanent injunction** was entered against Torrent, prohibiting any infringing activity related to ANDA No. 211107.
Key Legal Issues
This resolution reinforces the potency of the Hatch-Waxman Act, particularly **35 U.S.C. § 271(e)(2)**, which defines the filing of an ANDA for a patented drug as an act of infringement. Torrent’s explicit admission of validity and infringement stands out, as many ANDA litigations result in settlements without such a definitive concession. This binding judicial admission forecloses future challenges related to this ANDA, providing Actelion with robust and expedited protection for its macitentan patent estate in the District of New Jersey, a key venue for pharmaceutical IP disputes.

The primary patent was U.S. Patent No. 7,094,781 (US7094781B2), designated the “Licensed Patent” in the consent judgment. U.S. Patent No. 10,946,015 (US10946015B2) was also identified among the patents involved in the litigation.
Torrent admitted that US7094781’s claims are valid, enforceable, and would be infringed by commercial activities related to ANDA No. 211107 covering generic macitentan 10 mg tablets. The parties resolved for undisclosed consideration, and a permanent injunction was entered.
It establishes a binding judicial record of US7094781’s validity in the context of ANDA No. 211107, and signals to other potential ANDA challengers that Actelion will enforce its patent estate aggressively and with speed.
