Short Summary
The petitioner, a patentee, challenged actions of the State regarding e-rickshaws, asserting that defendants were infringing his patent on echo friendly vehicles. The court affirmed the petitioner's status as a patent holder and held that any license granted by the State in violation of the existing injunction would be void ab initio.
Detailed Summary
When a government decides to roll out a new wave of eco-friendly vehicles, it doesn't get to ignore the inventor who already patented the technology. This case is a stark reminder that even the State must respect the boundaries of a valid patent right, and no license issued in defiance of a court-ordered injunction can stand.
The petitioner in this matter was a patentee holding rights over eco-friendly vehicles, specifically e-rickshaws. As the holder of this patent, he had secured an existing injunction restraining others from infringing his patented technology. Despite this legal protection, the State proceeded with actions that allegedly facilitated the manufacture, sale, or operation of e-rickshaws falling within the scope of the petitioner's patent. The petitioner approached the court through a writ petition (WP-11061W-2017), filed on 21 April 2017, challenging the State's conduct and the licenses it had granted to third parties in the e-rickshaw space.
The petitioner argued that the defendants, including State authorities, were enabling infringement of his patent by issuing licenses or permissions that allowed third parties to operate e-rickshaws covered by his patent claims. He relied on the existing injunction that already restrained such infringement, contending that the State's actions effectively undermined and violated that court order. The respondents, on the other hand, appeared to justify their licensing activities on the basis of public policy and the promotion of eco-friendly transportation, suggesting that the State's regulatory powers should not be curtailed by a private patent right.
The court affirmed the petitioner's status as a valid patent holder and recognized the force of the existing injunction restraining infringement. Critically, the court held that any license granted by the State in violation of that injunction would be void ab initio, meaning it would be treated as if it never existed. The court made clear that an order restraining infringement based on a valid patent right binds government authorities just as it binds private parties, and the State cannot use its licensing power to authorize what a court has already prohibited.
For founders, inventors, and IP professionals, the lesson is powerful: a patent is not just a piece of paper, it is a legal right that even the government must respect. If you hold a valid patent and have secured an injunction against infringement, do not assume that State-issued licenses or regulatory approvals automatically trump your rights. Conversely, if you are a government body or licensee, never assume that a State license gives you a safe harbor against an existing patent injunction. Always conduct thorough patent due diligence before launching or licensing any technology, because licenses issued in defiance of a court order carry no legal weight and can be struck down as if they never existed.
