Delhi Court Expands Product-By-Process Claims in Landmark Ruling

January 13, 2025

The article published on January 11, 2025, details the extensive analysis and influence of a groundbreaking verdict delivered on February 7, 2024, by the Delhi High Court, revolutionizing the understanding and application of product-by-process claims within Indian patent law. This landmark ruling emphasizes the importance of protecting novel and inventive products irrespective of their manufacturing processes, particularly within the pharmaceutical industry where products often comprise complex structures that cannot be adequately defined by their form alone. The decision marks a significant evolution in Indian patent jurisprudence, aligning it closer to global standards practiced in jurisdictions like the European Union, the United Kingdom, and the United States.

Expansion of Product-By-Process Claims

The ruling by the Delhi High Court marked a pivotal shift in the scope of product-by-process claims, previously constrained within the narrowly defined confines of the specific manufacturing processes disclosed in patent applications. Justices Yashwant Varma and Dharmesh Sharma underscored the importance of extending patent protection to products deemed novel and inventive, independent of the methods used to produce them. This broader interpretation is especially significant in sectors like pharmaceuticals, where the structural complexity of products often necessitates a reliance on process-based descriptions to establish their uniqueness and inventive nature.

The broadening of these claims encouraged a more inclusive approach to patent protection, providing a flexible framework that recognizes the intrinsic value and innovation embedded in the products themselves rather than solely focusing on their manufacturing methodologies. By decoupling product protection from process specificity, the Court’s decision effectively enhanced the robustness and relevance of patent claims, facilitating greater protection for intricate and novel inventions that defy precise structural definition.

Case Background and Legal Dispute

The landmark ruling stemmed from an intricate patent case involving Vifor International’s patent IN’536, which revolved around Ferric Carboxymaltose (FCM), a specialized iron-carbohydrate complex. Vifor International, facing alleged patent infringement accusations from Corona Remedies and MSN Laboratories, initiated appeals following the rejection of an interim injunction by a single judge. This denial catalyzed the ensuing appeals process, culminating in this transformative judicial determination. The case brought to light fundamental legal questions, including whether product-by-process claims inherently protect the product itself or limit protection exclusively to products created using a specified manufacturing process.

The disputes also scrutinized the criteria necessary to discern whether competing products infringe on existing product-by-process claims when alternative manufacturing methods are employed. In this context, the Court’s analysis provided critical insights and set precedent for interpreting and evaluating such claims, balancing the necessity for innovation incentives with equitable enforcement of patent rights.

Global Patent Practices and Jurisprudence

The article provides a detailed examination of global patent practices, with a particular focus on how major jurisdictions such as the European Patent Office (EPO), United Kingdom, and United States address product-by-process claims. These jurisdictions collectively emphasize the novel and inventive nature of products over their manufacturing processes, offering a broader and more forward-thinking approach to patent protection. This trend underscores the crucial role that such claims play, especially in fields like pharmaceuticals, where the inherent complexity of products often precludes a thorough structural description.

In these global perspectives, the emphasis remains on recognizing the inventive aspects of products, rather than the precise methods of their production. Such a stance ensures that the essence of innovation—an inventive step or novel contribution to the existing body of knowledge—is adequately protected. The Delhi High Court’s ruling hence aligns with these international practices, fostering a more inclusive, balanced, and innovation-driven patent landscape within India, signaling a modernization of its principles and practices.

Court’s Analysis and Observations

The Division Bench meticulously analyzed the nuances of product-by-process claims, rejecting restrictive interpretations that bound patent protection to specified manufacturing processes. Instead, the Court championed a more holistic approach, asserting that the product’s novelty and inventiveness must be paramount in evaluating patentability. This approach necessitates assessing the innovation of the product independently from the process steps delineated in the claims.

Furthermore, the Court clarified that consistent criteria must be applied during patentability and infringement assessments, ensuring that innovative products receive comprehensive protection throughout their lifecycle. This approach fortifies the patent framework, enabling inventors to safeguard their pioneering contributions effectively, irrespective of the processes employed during production. It establishes a foundation for a more reliable and equitable analysis of product-by-process claims, reinforcing the integrity and consistency of patent protection.

Main Findings

The core findings of the judgment articulate pivotal clarifications and expansions within the scope of product-by-process claims:

  1. The Court definitively established that patent protection must extend to the novel and inventive product outlined within the claims, irrespective of the specific processes used in its manufacture. This finding underscores the protection of innovation over the procedural intricacies involved in creating the product.
  2. The distinction between “obtained by” and “obtainable by” was thoroughly clarified, with the former denoting products directly resulting from a specified process. In contrast, the latter encompasses products derivable through various methods. This distinction broadens the scope of claims, ensuring the protection of innovative products achieved through diverse manufacturing techniques.
  3. The ruling emphasized that process terms within claims should serve as explanatory aids, necessitating consistent novelty assessments during both patent grant and infringement evaluation stages. This consistency supports a cohesive and robust enforcement framework, providing clear guidelines for innovators and patent examiners.

Implications for the Pharmaceutical Industry

This verdict signifies a seminal shift in the landscape of Indian patent law, particularly for the pharmaceutical sector, where many inventions rely on intricate production processes rather than straightforward structural definitions. By focusing on the novelty and inventive nature of products, the ruling harmonizes Indian patent practices with leading international standards, particularly those upheld by the EPO, UK, and US. This approach promotes broader protection for innovative products, driving advancements in fields rife with complex technological and scientific challenges, such as pharmaceuticals, biotechnology, and chemical engineering.

The judgment implicitly sets a benchmark for an inclusive and equitable approach to patent protection, fostering a regulatory environment conducive to innovation. This environment supports competitive advancements, ensuring that novel contributions receive the recognition and protection necessary to thrive in a globalized marketplace. The ruling underscores the need for a balanced patent system that accommodates the complexities of modern innovation, facilitating continued growth and development within key technological sectors.
