Kerala High Court Impleads Breast Cancer Patient in Suo Motu Case on Patented Drug Pricing

The Kerala High Court on Friday allowed a 49-year-old breast cancer patient from Malappuram to be impleaded as an additional respondent in a suo motu petition examining the exorbitant pricing of life-saving patented drugs, Ribociclib and Abemaciclib. Justice Harisankar V. Menon, presiding over the matter, observed that the court is actively seeking a resolution and indicated that if the patented drugs cannot be substituted with a cheaper alternative, it may consider directing the central government to intervene under the Patents Act.

The case, originally filed in 2022 by a breast cancer patient from Ernakulam who subsequently succumbed to the disease, was converted into a suo motu proceeding by the court to address the larger public interest. The petition has now gained urgency following a request from the Supreme Court of India for expeditious disposal. The court has fixed September 3 for final arguments, directing key expert institutions to file affidavits on the therapeutic interchangeability of the drugs in question.

Background: A Lifeline Cut Short

The original petitioner had challenged the prohibitive costs of patented breast cancer medications, arguing that the prices placed an unbearable burden on patients. After her death, the court decided to continue the case suo motu , recognizing that the issue transcended individual interests and implicated the fundamental right to health. The petition invokes Sections 83, 92, and 100 of the Patents Act, 1970, which provide for general principles governing patents, compulsory licensing, and government use of patented inventions in cases of extreme necessity.

Section 92 empowers the government to grant compulsory licenses for patented drugs when the reasonable requirements of the public are not met or when the drug is not available at a reasonably affordable price. Section 100 authorizes the government to requisition life-saving medicines for its own purposes, including for supply to government hospitals. The court’s exploration of these provisions signals a potential shift toward greater state intervention in pharmaceutical pricing.

The Drug Dilemma: Palbociclib as a Substitute

During the July 15 hearing, the court impleaded the National Cancer Institute (Jhajjar), Chittaranjan National Cancer Institute (Kolkata), the Regional Cancer Centre (Thiruvananthapuram), and the Drug Controller General of India to obtain expert opinions on whether Palbociclib—a cheaper, locally manufactured drug no longer under patent—can be used as a substitute for the patented Ribociclib and Abemaciclib.

The Drug Controller General of India filed an affidavit stating that the question of therapeutic interchangeability is a clinical decision for treating oncologists and that the Central Drugs Standard Control Organisation (CDSCO) is not in a position to opine on the matter based solely on regulatory approval records. This response has left the court without a definitive answer, prompting it to seek independent expert evaluations from the impleaded cancer institutes.

Amicus curiae Maitreyi Sachidananda Hegde emphasized that the Drug Controller’s affidavit failed to conclusively address whether Palbociclib could serve as a substitute. The court recorded this concern, noting that the affidavit did not provide a clear position on interchangeability.

Court’s Oral Observations and Potential Directions

During the proceedings, Justice Menon orally remarked, “We will find a solution… The only question is whether this is a substitute or not. Suppose it is not a substitute, I may, perhaps, issue a direction to the central government.” This statement signals the court’s willingness to invoke its constitutional powers under Article 226 and the Patents Act to compel the government to take action, whether through compulsory licensing, price capping, or direct procurement of affordable alternatives.

The court also directed Additional Solicitor General of India P. Sreekumar to liaise with the impleaded expert institutions to ensure their affidavits are submitted by the next hearing. The urgency is underscored by the Supreme Court’s request, made on July 17, 2026, in a related suo motu writ petition, urging the Kerala High Court to dispose of the matter without delay.

Legal Implications: Patent Law Meets Public Health

This case represents a critical intersection of patent law and public health. The Patents Act allows for compulsory licensing under Section 92, but its invocation is rare and often mired in procedural complexities. If the court finds that Palbociclib is a viable substitute, it could pave the way for a broader policy shift, encouraging the use of off-patent generics in lieu of expensive patented drugs. Conversely, if no substitute exists, the court may direct the government to exercise its powers under Section 100 to requisition Ribociclib and Abemaciclib at reasonable prices.

The involvement of the Supreme Court adds a layer of judicial oversight, reinforcing the principle that access to affordable medicines is a facet of the right to life under Article 21. The outcome could set a precedent for similar challenges against high-priced patented drugs, particularly for cancer and rare diseases.

Impact on Legal Practice and Healthcare

For legal practitioners, this case highlights the growing judicial activism in healthcare policy. The court’s willingness to implead expert bodies and seek scientific opinions underscores the need for interdisciplinary approaches in public interest litigation. Lawyers specializing in intellectual property and constitutional law should carefully monitor the September 3 hearing, as the court’s final order may clarify the scope of judicial power in compelling state action on drug pricing.

Healthcare providers and patient advocacy groups will be watching closely. If the court orders the government to procure Palbociclib as a substitute, it could reduce treatment costs for breast cancer patients significantly. However, oncologists caution that therapeutic interchangeability is not guaranteed; individual patient responses to different drugs may vary, necessitating a case-by-case evaluation. The court has acknowledged this complexity and is seeking expert input before making any sweeping directive.

Conclusion: A Decisive Hearing Ahead

As the case moves toward final arguments on September 3, all eyes are on the expert affidavits from the National Cancer Institute, Chittaranjan National Cancer Institute, and the Regional Cancer Centre, Thiruvananthapuram. Their clinical opinions will be pivotal in determining whether Palbociclib can replace Ribociclib and Abemaciclib. The court’s earlier observation that it may issue a direction to the central government if no substitute exists signals a potential landmark ruling on compulsory licensing and government use of patented drugs.

For the impleaded patient and countless others facing similar battles, the Kerala High Court’s proactive stance offers a glimmer of hope. The case not only challenges the exorbitant pricing of essential medicines but also reaffirms the judiciary’s role as a guardian of fundamental rights in the face of market failures.
