Endo Pharmaceuticals Inc. v. Lupin Atlantis Holdings SA: A Comprehensive Litigation Summary and Analysis

Last updated: January 19, 2025

Background of the Case

The litigation between Endo Pharmaceuticals Inc. and Lupin Atlantis Holdings SA, filed on July 28, 2017, in the Eastern District of Texas (Case No. 2:17-cv-00558), revolves around allegations of patent infringement under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly known as the Hatch-Waxman Act[1][3].

Patents in Dispute

Endo Pharmaceuticals Inc. alleged that Lupin Atlantis Holdings SA infringed on several of its patents, including U.S. Patent No. 7,229,636, U.S. Patent No. 7,404,489, U.S. Patent No. 7,879,349, and U.S. Patent No. 8,003,353. These patents pertain to Endo's product, Nascobal, a cyanocobalamin nasal spray used for the treatment of vitamin B12 deficiency[3].

Venue and Jurisdiction

A significant aspect of the case was the dispute over the proper venue. Lupin Atlantis Holdings SA, a foreign defendant, filed a motion to dismiss the complaint under Federal Rule of Civil Procedure 12(b)(2) and (3) or to transfer the venue under 28 U.S.C. §§ 1404 or 1406. The court considered the motion, noting that foreign defendants can be sued in any judicial district under 28 U.S.C. § 1391(c)(3)[1][4].

Transfer of Venue

Despite the initial ruling that the case could proceed in the Eastern District of Texas due to the federal venue laws not applying to foreign defendants, the court ultimately granted Lupin's alternative motion to transfer the venue to the District of New Jersey. This decision was based on factors such as the ease of access to proof, the availability of compulsory process, and witness convenience, all of which favored transfer to New Jersey. The court highlighted that many relevant documents and physical evidence, including samples of the ANDA product, were located in New Jersey[1][4].

Role of Novel Laboratories, Inc.

Lupin argued that its registered U.S. FDA agent, Novel Laboratories, Inc., a wholly-owned subsidiary of Lupin, was responsible for all research and development and regulatory filings related to the ANDA product. Novel's office in Somerset, New Jersey, housed key documents and evidence, further supporting the transfer to New Jersey[1].

Endo's Arguments and Counterarguments

Endo countered that Lupin, not Novel, was the sole party to file the ANDA and should not be allowed to selectively disregard the corporate veil. However, Lupin provided affidavits and letters authorizing Novel employees to act on its behalf, which supported the transfer[1].

Infringement Claims

Endo alleged that Lupin's ANDA product would infringe on the claims of the patents in question upon FDA approval. The allegations included direct infringement, inducement of infringement, and contributory infringement under 35 U.S.C. §§ 271(a), (b), and (c). Endo also sought declaratory judgments and requested an injunction to prevent Lupin from manufacturing, using, offering for sale, selling, and importing the ANDA product[3].

Irreparable Harm and Attorney Fees

Endo argued that it would be irreparably harmed if Lupin were not enjoined from infringing the patents, as it did not have an adequate remedy at law. Additionally, Endo claimed that the case was exceptional and sought an award of reasonable attorney fees under 35 U.S.C. § 285[3].

Transfer to District of New Jersey

The case was eventually transferred to the District of New Jersey, where it was assigned to Judge Freda L. Wolfson (Case No. 3:18-cv-10952). The litigation concluded on June 24, 2019[5].
