Madras High Court Protects Inventor's Rights: Late Patent Examination Request Accepted Despite Agent's Error

Introduction

In a significant ruling for intellectual property practitioners, the Madras High Court has held that a patent application cannot be deemed abandoned solely due to an inadvertent calculation error by an Indian patent agent in determining the deadline for filing a request for examination. Justice N. Anand Venkatesh, in his order dated December 18, 2025, allowed the writ petition filed by US inventor Edward Charles Troppi Smythe, directing the Indian Patent Office to accept and process the belated request under Form 18 for patent application No. IN202447028876. The invention, titled “Prediction, Visualisation and Remediation of Satellite Conjunctions,” leverages machine learning to forecast satellite collisions, highlighting the court's consideration of the innovation's potential value. This decision underscores the judiciary's reluctance to penalize inventors for procedural lapses attributable to agents, particularly in cross-border filings, without evidence of intentional abandonment.

The case, WP(IPD) No. 12 of 2025, involved Smythe challenging the Patent Office's refusal to entertain his examination request, which was filed late due to a miscalculation of the 31-month statutory period under Section 11B of the Patents Act, 1970. Represented by advocate Preeti Mohan, the petitioner argued reliance on the agent's advice, while the respondents, defended by Central Government Standing Counsel K. Subbu Ranga Bharathi, insisted on strict adherence to timelines. This ruling not only revives Smythe's application but also sets a precedent for leniency in similar scenarios, potentially easing the burden on foreign applicants navigating India's patent system.

Case Background

Edward Charles Troppi Smythe, a US citizen residing in San Diego, California, developed an innovative system using machine learning to predict, visualize, and remediate potential conjunctions (collisions) between satellites in low Earth orbit. With the proliferation of orbiting bodies, traditional supercomputer-based calculations struggle to forecast risks beyond a few days. Smythe's invention addresses this by enabling predictions up to 30 days in advance, allowing prioritization, visualization, and preventive measures like satellite control adjustments.

Smythe's patent journey began on September 10, 2021, with a provisional application in the US. He filed a second US application on September 8, 2022, followed by a Patent Cooperation Treaty (PCT) application on September 9, 2022, claiming priority from both US filings. The Indian national phase application was entered through an Indian patent agent, claiming priority from the first US filing of September 10, 2021. This placed the deadline for filing the request for examination—governed by Section 11B of the Patents Act and Rule 24B of the Patents Rules, 2003—at 31 months from the priority date, expiring on April 10, 2024. (Note: The rule was amended effective March 15, 2024, reducing the period from 48 to 31 months.)

The dispute arose from the Indian agent's error: instead of calculating from the 2021 priority date, the agent erroneously used the 2022 second US filing date, informing Smythe that the deadline was April 8, 2025. US IP attorneys had been following up with the agent, who confirmed in an email dated October 14, 2024, that formalities were complete and the deadline was in 2025. When the agent attempted to file on December 10, 2024, the Patent Office's online portal rejected it as "Not valid." Smythe promptly emailed the office for assistance, but on December 30, 2024, he was informed the period had lapsed, deeming the application withdrawn.

Aggrieved, Smythe filed the writ petition in the Madras High Court seeking a mandamus to direct acceptance of the Form 18 request. The case timeline reflects the complexities of international patent prosecution: from initial US filing in 2021 to the writ in early 2025, underscoring delays inherent in relying on local agents for foreign applicants.

The legal questions at the core were: (1) Whether an agent's inadvertent error in deadline calculation constitutes abandonment under Section 11B, justifying the application's withdrawal? (2) Can courts intervene via writ jurisdiction to condone such procedural delays absent intent to abandon, balancing statutory timelines with substantive rights?

Arguments Presented

The petitioner's counsel, Ms. Preeti Mohan, emphasized that Smythe had no intention to abandon the application and fully relied on the Indian agent's expertise. She detailed the sequence: the agent's confirmation of completed formalities and the erroneous email setting the deadline as April 8, 2025. Upon the portal rejection, Smythe immediately sought redress, demonstrating diligence. Mohan argued that Section 11B and Rule 24B aim to ensure examination requests are timely but do not prescribe automatic abandonment for agent errors, especially without contributory negligence by the applicant. She relied on the Madras High Court's prior ruling in Chandra Sekar v. Controller of Patents and Designs (2022 SCC OnLine Mad 5172), where a similar agent negligence led to condonation of delay. Mohan stressed Smythe's status as a foreign inventor dependent on local representation, arguing that punishing him would defeat the Patents Act's objective of fostering innovation.

The respondents, represented by Mr. K. Subbu Ranga Bharathi, countered that the statutory timeline under Section 11B is mandatory. Rule 24B(1) requires the request within 31 months from priority or filing, whichever earlier, with Rule 138 allowing only a one-month extension by the Controller—totaling up to 32 months, but no further discretion for writ courts. They asserted the application was deemed withdrawn post-April 10, 2024, as no request was filed, implying abandonment. Bharathi opposed interference, citing the need for certainty in patent prosecution to prevent backlog and abuse. He distinguished the case from precedents, arguing no exceptional circumstances justified overriding the law's plain language, which ties examination to a timely request by the applicant or interested person.

Both sides clashed on intent: petitioners highlighted proactive steps post-error discovery, while respondents viewed the lapse as the applicant's responsibility, regardless of agent involvement.

Legal Analysis

Justice Venkatesh's reasoning centered on interpreting Section 11B alongside Rules 24B and 138, emphasizing that timelines serve procedural efficiency but cannot extinguish substantive rights without evidence of deliberate abandonment. The court clarified that while the 31-month period (post-2024 amendment) is strict, Rule 138's one-month extension underscores limited discretion, yet writ jurisdiction allows equity where agent errors mislead applicants.

Key to the analysis was distinguishing procedural lapses from intentional relinquishment. The judge noted Smythe's chain of filings—US provisional (2021), second US (2022), PCT (2022), and Indian entry—evidenced commitment. The agent's miscalculation stemmed from using the wrong priority date, a bona fide error not attributable to Smythe, who depended on the agent as advised by US counsel.

The court drew heavily from precedents. In Chandra Sekar v. Controller of Patents and Designs (2022 SCC OnLine Mad 5172), it condoned delay due to attorney negligence, holding: "In the absence of any material to show that the petitioner has intended to abandon his right... valuable statutory rights... cannot be completely deprived of merely because the patent application... has not been diligently presented by the agent." This was directly analogous, as both involved foreign applicants relying on Indian agents without intent to abandon.

Further, the judgment referenced the Delhi High Court's Bry-Air Prokon SAGL v. Union of India (W.P.(C)-IPD 25/2022, October 17, 2022), which elaborated on abandonment requiring affirmative intent, not mere delay. Justice Venkatesh adopted this, stating procedural rules must yield to equity absent bad faith, aligning with the Patents Act's pro-innovation ethos under Article 300A (right to property).

The analysis distinguished related concepts: abandonment implies voluntary surrender (e.g., non-response to office actions), unlike here—a single deadline miss due to misinformation. The court weighed the invention's merit: machine learning for satellite risk prediction addresses global space debris concerns, justifying leniency. No statutory bar to condonation was found, as Section 11B conditions examination on request but doesn't preclude judicial review under Article 226.

This nuanced approach balances strict timelines (to curb dormant applications) with fairness, particularly for non-resident applicants under the PCT framework, where priority claims complicate calculations.

Key Observations

The judgment is replete with pivotal observations emphasizing equity over rigidity:

• On agent negligence: "Admittedly, the reason for delay... is only due to the sheer negligence on the part of the Indian Attorney. It is also not the case of the respondents that there was contributory negligence on the part of the petitioner, and he had an intent to abandon the patent."

• On substantive rights: "In the absence of any concrete material to show that the petitioner has not taken any steps to pursue his application, it cannot be presumed that he had intention to abandon his right."

• On the invention's value: "The ever-increasing number of orbiting bodies in low Earth orbit has made it infeasible to calculate potential conjunctions... Disclosed embodiments utilize machine learning to predict potential conjunctions... faster than state-of-the-art systems by orders of magnitude. This enables potential conjunctions to be identified well in advance (e.g., 30 days or more)."

• On judicial intervention: "For the mistake committed on the part of the Indian Agent, the petitioner should not be deprived of pursuing the patent application in the absence of any concrete material to show that the petitioner has not taken any steps to pursue his application."

These quotes, extracted from paragraphs 14, 16, 19, and 18 of the order, encapsulate the court's humanistic approach, prioritizing innovation over technical forfeitures.

Court's Decision

The Madras High Court allowed the writ petition, issuing a mandamus directing the Controller General of Patents, Designs and Trade Marks (Respondent No. 1), the Joint Controller in Chennai (Respondent No. 2), and the Union of India (Respondent No. 3) to "accept the petitioner's request for examination under Form 18 in Indian Patent Application No. IN202447028876 and process the same in accordance with law and pass appropriate orders, as expeditiously as possible." No costs were imposed.

This decision revives Smythe's application, enabling substantive examination on merits, potentially leading to grant if novel and inventive. Practically, it mandates the Patent Office to override the lapsed status, injecting the request retroactively and queuing it for review—likely expedited given the order.

Implications are profound for future cases. It reinforces that agent errors, common in international filings (over 20% of Indian applications are PCT nationals), won't automatically doom applications if intent is absent. This may encourage more foreign inventors, boosting India's IP ecosystem, but risks workload strain if liberally applied. Patent agents must heighten diligence in priority calculations, facing potential liability. For legal practice, it signals writ courts' willingness to invoke equity under Article 226, citing Chandra Sekar and Bry-Air , potentially influencing other IP jurisdictions. Overall, it promotes access to protection, aligning with TRIPS obligations, though offices may seek rule amendments for clarity.

In a broader context, integrating details from contemporaneous reports, this ruling echoes the Madras High Court's push for systemic reforms, as seen in its January 7, 2026, directive in A. Radhakrishnan v. Secretary, Ministry of Home Affairs to form district committees abolishing the "orderly system" in police usage. While unrelated, both reflect the court's role in rectifying administrative lapses—procedural in patents, cultural in policing—ensuring rights aren't lost to oversights. This patent decision, thus, fortifies inventor confidence in India's maturing IP regime.
