Glaxo Smith Kline Plc v. Controller Of Patents & Designs

Every founder dreams of securing exclusive rights to their innovation, but what happens when the very law that granted those rights is suddenly struck off the books? For Glaxo SmithKline, this was not a hypothetical—it was a high-stakes reality. Their case before the Supreme Court became a defining moment for understanding how Indian law treats rights that have already been earned, even when the statute that created them is repealed. The lesson stretches far beyond pharmaceuticals: any business that relies on statutory protections must understand the doctrine of vested rights.

Glaxo SmithKline Plc and others (the appellants) had sought an Exclusive Marketing Right (EMR) under the relevant provisions of the Patents Act. The application was processed by the Controller of Patents & Designs (the respondent). The matter escalated through the legal system, and at one point, the High Court entertained appeals on the premise that no further consideration of the EMR application was possible. The turning point came in 2005, when an amendment to the Patents Act repealed the chapter that governed EMRs. Suddenly, the legal foundation beneath Glaxo SmithKline's claims appeared to crumble, and the question became whether the appellants still had any standing to pursue their challenge.

The appellants argued that even though the chapter governing EMRs had been repealed by the 2005 amendment, their right to challenge the earlier orders of the Controller of Patents & Designs had already been accrued. They contended that this was a vested right, protected under Section 6 of the General Clauses Act, which preserves rights and liabilities that have already been earned when an enactment is repealed. On the other side, the respondents and the High Court's reasoning leaned on the position that once the relevant chapter was gone, no further consideration of EMR applications could be entertained—the repeal effectively ended the conversation. The legal friction was clear: does the repeal wipe the slate clean, or does it leave behind the rights that were already in motion?

The Supreme Court ruled in favor of Glaxo SmithKline and the other appellants. The Court held that, by virtue of Section 6 of the General Clauses Act, the appellants' vested right to challenge the earlier orders remained alive even after the repeal of the relevant chapter by the 2005 amendment. Unless the repealing enactment contains a clear contrary intention, rights that have already accrued under the old law are not extinguished simply because the statute itself has been removed. The decision restored the appellants' ability to pursue their challenge, confirming that the repeal did not strip them of their standing.

For founders, startup leaders, and IP professionals, the lesson is foundational: rights that have already been acquired or accrued under a statute do not automatically disappear when that statute is repealed. Before assuming that a legal pathway has been closed by new legislation, examine whether the repealing act contains explicit language that destroys existing rights. If it does not, Section 6 of the General Clauses Act may shield your accrued rights and keep your legal remedies alive. Always document and pursue your statutory claims diligently—because timing matters, and a right earned today may still protect you tomorrow, even if the law that created it is rewritten.
