When strategizing patent portfolios, divisional applications play a role similar to the principle of ‘divide and rule.’ This strategy, often associated with historical and political contexts, in the domain of patents translates into optimizing protection amongst evolving technological and legal complexities. Divisional applications also serve as a safeguard, allowing inventors and companies to protect their inventions, even against initial rejections. This is especially crucial in industries where patent protection is key, offering extended control over inventions and potentially influencing market competition. With India’s legal landscape around divisional applications evolving to align with global practices, it raises a pertinent question: Is India on the brink of seeing a surge in the filing of divisional patent applications?
To explore this question, let us examine the development of India’s approach to divisional patent applications, particularly through key legal decisions:
The Foundation: LG Electronics and the IPAB’s Interpretation
A key turning point in this narrative was the Intellectual Property Appellate Board’s (IPAB) decision in the LG Electronics case. This ruling played a crucial role in interpreting Section 16 of the Patents Act, 1970, laying down foundational criteria for divisional patent applications. It emphasized the necessity of having distinct inventions within the claims of divisional applications, thereby setting a benchmark that would shape future legal interpretations and rulings.
The ESCO Corporation Case: A Refined Understanding
In 2020, the IPAB’s interpretation in the ESCO Corporation v Controller of Patents & Designs case further clarified the requirements for divisional applications. It emphasized that the claims of a divisional application must derive from the parent application’s claims, reinforcing the principle of “what is not claimed is disclaimed.” This decision narrowed the scope for divisional applications, aligning it closely with the explicit claims in the parent application.
Boehringer Ingelheim: A Restrictive Interpretation
The Delhi High Court’s decision in Boehringer Ingelheim International GMBH v The Controller of Patents in 2022 took a more restrictive approach. The court categorically held that a divisional application was maintainable only if the parent application contained a plurality of inventions explicitly claimed. This interpretation required a clear distinction of inventions in the parent application’s claims, significantly restricting the scope for filing divisional applications and impacting patent strategies across industries.
Syngenta Limited v. Controller of Patents and Designs: Overturning the Past
The Syngenta Limited v. Controller of Patents and Designs case in October 2023 challenged and eventually overturned the precedent set by the Boehringer decision. Key clarifications made by the Division Bench of the Delhi High Court include:
a) Voluntary Divisional Applications: The court held that under Section 16(1), an applicant could voluntarily divide a patent application without a lack of unity objection from the Controller, thus expanding the potential for filing divisional applications beyond the constraints imposed by previous interpretations.
b) Scope Beyond Parent Application Claims: Crucially, the court ruled that the subject matter of a divisional application need not be limited to the claims of the parent application. It could include any invention disclosed in the provisional or complete specification that may have been filed. This interpretation significantly broadened the scope for filing divisional applications, departing from the restrictive claim-based approach of the Boehringer decision.
c) Reinterpretation of ‘What Is Not Claimed Is Disclaimed’: Offering a fresh perspective, the Division Bench clarified the scope of ‘what is not claimed is disclaimed.’ This principle, they noted, is more aligned with infringement analysis and does not hold as much weight in the context of claim drafting for divisional patent applications.
Analyzing the Potential Increase in Divisional Filings
Given the Syngenta ruling’s alignment with global practices, a surge in divisional patent filings in India seems likely. This anticipation is rooted in the following:
a) Strategic Flexibility: The outcome offers a more flexible approach, allowing for the filing of divisional applications even when the plurality of inventions are not claimed in the parent application.
b) Reflecting Global Trends: This shift could lead to an adoption of strategies prevalent in other jurisdictions, encouraging a rise in divisional filings.
c) Enhanced Protective Measures: The Syngenta decision could make divisional applications a more appealing strategy for patent applicants, especially in fast-evolving sectors. This approach allows for flexible protection of different aspects of an invention, aligning well with the needs of businesses navigating rapidly changing technological landscapes.
In light of the progressive judicial stance, India may witness an increase in the filing of divisional patent applications. This potential rise reflects not just a legal shift but a strategic one, influencing patent filing approaches and competitive dynamics in various patent-centric industries especially, pharmaceuticals and emerging computer-related technologies. The anticipation of this trend necessitates a reevaluation of patent strategies by businesses and professionals, considering the more dynamic and flexible environment for patent protection in India. As India increasingly aligns more closely with global patent practices, increased employment of divisional applications is expected to become a mainstream approach among patent practitioners.
