Piramal Enterprises Limited v. Chemiloids and others

In the world of pharmaceuticals and specialty chemicals, the most valuable asset isn't always a patent — it's the know-how. The step-by-step instructions, the precise conditions, the carefully guarded Standard Operating Procedures that turn raw materials into high-value products. When that knowledge slips into the wrong hands, the legal battle isn't just about money; it's about proving what was taken, how it was used, and whether science itself can tell the difference. This is the story of how one major enterprise fought to keep its proprietary process from being replicated by a former partner.

Piramal Enterprises Ltd, a well-known name in the pharmaceutical and specialty chemicals space, found itself in a dispute with Chemiloids and seven other parties. At the heart of the conflict was a Standard Operating Procedure (SOP) — a confidential document detailing the process for extracting a substance referred to as SI containing a specific percentage of 7-HF. This SOP was shared with Chemiloids under the framework of a manufacturing agreement, meaning it was meant to be used only for the purposes defined within that contractual relationship. Piramal alleged that this confidential information was being used beyond the scope of the agreement, effectively giving Chemiloids and others an unfair advantage by leveraging proprietary knowledge without authorization.

The legal friction in this case centered on a fundamental question in intellectual property law: how do you prove that someone has misused confidential information when the "information" is a technical process rather than a tangible product? Piramal Enterprises argued that the SOP constituted protected confidential information, shared in confidence under a manufacturing arrangement, and that its unauthorized use by Chemiloids amounted to infringement of its trade secrets. The respondents, Chemiloids and the seven others, presumably contested the allegations, leading to a situation where the court needed more than legal arguments — it needed scientific evidence. The core dispute was not merely about whether the SOP was confidential, but whether the processes being used by Chemiloids were substantially derived from or identical to Piramal's proprietary method.

Recognizing the deeply technical nature of the dispute, the court took an unusual but decisive step: it appointed the Department of Chemical Engineering at IIT Madras as an Expert Commissioner. This was a strategic move to bring independent, authoritative scientific analysis into the legal proceedings. The Expert Commissioner was tasked with comparing the processes used by both parties — essentially conducting a forensic examination of the chemistry involved in extracting SI containing the specified percentage of 7-HF. By involving a premier academic institution, the court ensured that the comparison would be conducted with rigor, objectivity, and technical credibility. The matter resulted in an interim order, reflecting that the court was still in the process of gathering and evaluating the expert findings before issuing a final determination on the merits of the dispute.

For founders and business leaders, this case delivers a critical lesson: when you share confidential know-how with a manufacturing partner, vendor, or collaborator, you are placing your most valuable intellectual property in someone else's hands. The lesson here is twofold. First, ensure that your manufacturing agreements contain robust confidentiality clauses that clearly define what information is protected, how it may be used, and what constitutes a breach. Second, understand that if a dispute arises over the misuse of a technical process, courts are willing to bring in independent scientific experts to compare methodologies — meaning that the strength of your case will depend heavily on the clarity, documentation, and distinctiveness of your proprietary process. Protect your SOPs like you would protect your source code, because in the eyes of the law, they may be just as valuable.
