High Court of Madras Upholds Execution of Letters Rogatory in Patent Case

Background

In a significant ruling, the High Court of Madras addressed the petitions filed by Pfizer Inc. against Softgel Healthcare Private Limited regarding the execution of Letters Rogatory issued by the United States District Court. The case revolves around allegations of patent infringement concerning Pfizer's "441 Patent" for its drug VYNDAMAX®, used in treating transthyretin amyloid cardiomyopathy. Pfizer claims that the submission of Abbreviated New Drug Applications (ANDAs) by Indian pharmaceutical companies, including CIPLA and Zenara, infringes upon their patent rights.

Arguments

Pfizer argued that the Letters Rogatory were essential for obtaining evidence from Softgel , which they believed possessed relevant documents to support their claims in the U.S. litigation. They emphasized the need for international judicial assistance under the Hague Evidence Convention, asserting that the documents sought were crucial for proving their case.

Conversely, Softgel contended that they were a non-party to the U.S. litigation and thus could not be compelled to provide evidence. They raised concerns about confidentiality and the potential violation of Indian patent laws, arguing that the Indian Patent Office had previously rejected Pfizer's patent application for VYNDAMAX®.

Court's Analysis and Reasoning

The court analyzed the arguments presented by both parties, referencing the Hague Evidence Convention and the provisions of the Indian Code of Civil Procedure. It noted that the Letters Rogatory were issued in compliance with international treaties and that there were no legal restrictions preventing the execution of such requests in India. The court emphasized the importance of international comity and the need for cooperation between judicial systems in different countries.

The court also addressed Softgel 's confidentiality concerns, stating that a 'confidentiality club' would be established to protect sensitive information during the evidence collection process. The court found that the documents sought were specific enough to warrant the execution of the Letters Rogatory.

Decision

The High Court of Madras ruled in favor of Pfizer, allowing the execution of the Letters Rogatory and appointing a local commissioner to oversee the collection of evidence. The court mandated that all proceedings be conducted in camera, ensuring confidentiality for the parties involved. This decision underscores the court's commitment to facilitating international judicial assistance in patent disputes, reinforcing the significance of the Hague Evidence Convention in cross-border legal matters.
