Summary

The Delhi High Court clarified that the decisive point in time for patent grant is when the Controller signs the order under Section 15 — not when the order is uploaded on the IPO website, when the certificate is generated, or when the patent is entered in the register under Section 43.

"Once the Controller has signed the order of grant, the applicant acquires statutory rights under the Patents Act, 1970, and the process of uploading or certificate issuance is purely ministerial in nature and has no bearing on the legal effect of the grant." — Delhi High Court

Factual Background

Vertex Pharmaceuticals filed patent application (202017044455) for cystic fibrosis treatment. The Controller signed the order granting the patent on November 28, 2023. However, due to system limitations, the order was uploaded on the IPO website at approximately 5:25 pm on the same day. At 5:18 pm — seven minutes before upload — Mr. Velagala Suresh filed a pre-grant opposition under Section 25(1).

The Controller issued notice on December 8, 2023, treating the opposition as valid. Vertex filed a miscellaneous petition seeking dismissal, which the Controller rejected on April 5, 2024, holding the opposition valid and maintainable.

Legal Analysis

Date of Grant vs. Ministerial Acts: The Court emphasized that the "date of order" of a patent grant is the date on which the Controller passes (signs) the order, not the date of its upload or certificate generation. These subsequent acts are purely ministerial and do not affect the legal status of the grant.

Functus Officio: Once the order granting the patent was signed, the Controller became functus officio and lacked jurisdiction to entertain any pre-grant opposition or issue further notices.

Systemic Delays: The Court noted that delays in uploading or generating certificates are attributable to systemic issues within the IPO and not to any fault of the patentee, who should not suffer adverse consequences due to such delays.

Decision

The Court quashed the impugned notice and the Controller's order. The pre-grant opposition was held to be not maintainable as it was filed after the patent had already been granted by the Controller's signature.

Significance

This ruling provides crucial clarity on the precise moment of patent grant, protecting patentees from oppositions filed during administrative processing delays. It reinforces that statutory rights vest upon the Controller's decision, not subsequent administrative formalities.
