The Bombay High Court has held that where a patent matter is remanded solely to cure a violation of natural justice, the Patent Office cannot use the remand as an opportunity to restart the examination process by introducing fresh objections or new prior-art references.
Justice Arif S. Doctor allowed an application filed by Qualyst Transporter Solutions LLC and clarified that the Patent Controller’s jurisdiction on remand was limited to granting a fresh hearing on the existing record. The Court held that the Controller could not travel beyond the scope of the remand order by raising entirely new grounds of objection.
The dispute arose from a patent application that had been under examination for nearly a decade. In October 2025, the Bombay High Court had set aside an order of the Assistant Controller of Patents and Designs after the Patent Office conceded that certain objections had been raised for the first time during the hearing, without giving the applicant an opportunity to respond, thereby violating principles of natural justice. The matter was remanded for a fresh hearing before an independent Controller.
Following the remand, however, the Patent Office issued a fresh hearing notice in January 2026 introducing new objections and prior-art references that had never formed part of the original examination record. Qualyst Transporter Solutions approached the High Court contending that the Controller had exceeded the scope of the remand order.
The Court agreed with the applicant and held that the remand order was intended only to cure the procedural defect identified earlier, namely the denial of an opportunity to address objections raised for the first time during the hearing.
The Court observed that when the remand order was passed, the Patent Office had never suggested that further examination was required, nor had it sought liberty to introduce additional objections or fresh prior art. The examination stage had already concluded, and only a fresh hearing remained to be conducted. Rejecting the Patent Office’s contention that it retained authority to raise fresh objections during the remanded proceedings, the Court held:
“
“The Controller’s jurisdiction on remand was confined to curing the procedural defect identified in the Order of Remand, i.e., by giving the Petitioner a fresh hearing. It did not extend to reopening the examination process de novo by introducing fresh objections or new prior art references that had admittedly never been raised before.”
The Court further clarified that while the Patent Office could elaborate upon, clarify or further develop objections already emerging from the existing examination record, it could not introduce entirely new prior-art references or wholly new grounds of objection. Justice Doctor observed:
“
“What is impermissible, however, having regard to the peculiar facts of the present case and the limited scope of the Order of Remand, is the introduction of entirely new prior art references or wholly new grounds of objection.”
Allowing the application, the Court directed that the fresh hearing be completed and a decision be rendered within eight weeks. However, considering the wider ramifications of the ruling, the Court stayed the operation of its judgment for four weeks at the request of the Patent Office.
