In a significant legal development, the Delhi High Court has issued an interim injunction restraining Indian pharmaceutical major Dr. Reddy’s Laboratories and OneSource Nutra from manufacturing, selling, or distributing generic versions of a weight loss drug patented by Danish pharmaceutical company Novo Nordisk.
The dispute centers around semaglutide, the active ingredient in Novo Nordisk’s blockbuster drug Wegovy, which is used for chronic weight management and has gained global popularity due to its high efficacy in combating obesity. Semaglutide, also used in the diabetes medication Ozempic, has seen skyrocketing demand, making it a highly valuable asset for the company.
The Court’s Interim Order
On Thursday, Justice Sanjeev Narula of the Delhi High Court granted an ex parte ad interim injunction in favor of Novo Nordisk, barring Dr. Reddy’s and OneSource from infringing on the company’s patent rights related to semaglutide. The order came in response to a lawsuit filed by Novo Nordisk India Pvt. Ltd. and Novo Nordisk A/S, which alleged unauthorized use and commercialization of the patented compound by the defendants.
The court observed that a prima facie case of patent infringement had been established and that irreparable harm could be caused to Novo Nordisk if interim relief was not granted. The order restrains the defendants from importing, manufacturing, marketing, or offering for sale any product containing semaglutide until the matter is fully adjudicated.
Background of the Dispute
Novo Nordisk holds a valid Indian patent for semaglutide, which is protected until 2033. The company claimed that Dr. Reddy’s and OneSource had begun producing and marketing unauthorized generic versions of the compound in violation of its intellectual property rights.
In its petition, Novo Nordisk argued that such actions not only amounted to infringement but also posed a serious threat to its commercial interests and research investments in India and globally.
The Danish drugmaker submitted evidence including product listings and promotional material from the defendants, suggesting active commercialization efforts despite the subsistence of the patent.
Industry Impact
The injunction is likely to have far-reaching implications for the Indian pharmaceutical sector, particularly in the context of patent law enforcement and the growing market for obesity treatment drugs. With semaglutide-based therapies becoming a major growth driver for Novo Nordisk, the ruling underscores the increasing significance of patent protection in high-value therapeutic categories.
While Indian generic manufacturers have historically played a critical role in making affordable medications accessible, this case reaffirms the judiciary’s stance on respecting patent laws, particularly when infringement is clearly established.
Responses from the Parties
As of the time of publication, Dr. Reddy’s Laboratories has not issued an official statement on the court’s order. OneSource Nutra also remains silent on the issue.
Novo Nordisk, on the other hand, welcomed the decision, stating it was a “vindication of our ongoing commitment to protecting innovation and ensuring patient safety.” The company emphasized that unregulated generics could compromise treatment efficacy and patient outcomes.
Next Steps
The matter is scheduled for further hearing in July 2025, during which the defendants are expected to present their responses. Legal experts suggest that the final outcome could set a precedent for similar cases involving high-demand biologics and patented pharmaceuticals.
As India continues to balance public health interests with intellectual property rights, the resolution of this case will be closely monitored by stakeholders in the pharmaceutical and healthcare sectors both domestically and internationally.
