Topic 137 Patent Office Procedure

Topic 137 — Patent Office Procedure

This Module 15 opens the procedural dimension of Indian IP practice — moving from substantive law to operational mechanics of how applications are filed, examined, opposed, granted, and maintained. Patent Office Procedure in India is governed by the PATENTS ACT 1970, PATENTS RULES 2003, and the transformative PATENTS (AMENDMENT) RULES 2024 (notified 15 March 2024). The Indian Patent Office (IPO) is headquartered at Kolkata with branch offices in Mumbai, Delhi, and Chennai — established under Section 74 Patents Act. The Controller General of Patents, Designs and Trade Marks (CGPDTM) heads the office. The amended 2024 Rules introduced sweeping changes: REQUEST FOR EXAMINATION timeline reduced from 48 months to 31 MONTHS (effective 15 March 2024); FORM 3 frequency simplified (single submission within 3 months of FER); FORM 27 frequency reduced (every 3 financial years instead of annually); GRACE PERIOD provisions introduced (Form 31, ₹2,500 fee); CERTIFICATE OF INVENTORSHIP introduced (Form 8A under new Rule 70A); PRE-GRANT OPPOSITION fee introduced (₹4,000 for individuals/SMEs/startups; ₹20,000 for others); POST-GRANT OPPOSITION fee ₹40,000; OPPOSITION BOARD timeline reduced from 3 to 2 months; EXTENSION OF TIME relaxed (Rule 138 now allows up to 6 months extension). The patent grant procedure follows: FILING (Section 7) → PUBLICATION (Section 11A — 18 months) → REQUEST FOR EXAMINATION (Section 11B — 31 months) → FIRST EXAMINATION REPORT (FER) → RESPONSE TO FER (6 months + 3 month extension) → HEARING → GRANT OR REFUSAL → POST-GRANT OPPOSITION (12 months from grant publication). Two opposition tracks: PRE-GRANT (Section 25(1) by any person) and POST-GRANT (Section 25(2) by person interested only). Recent cases shaping procedure: Vishal Solanke v. Controller (2025:BHC-OS:4952) — pre-grant opposition and examination distinct tracks; Novartis v. Natco (LPA 50/2023) — distinct examination/opposition processes; Open TV v. Controller (2023:DHC:3305) — single valid ground sufficient for refusal. Patent agents must qualify under Section 126 + pass Patent Agent Examination (PAE). This topic walks through the complete IPO procedure — filing, examination, opposition, grant, post-grant maintenance, and recent reforms.

For inventorship, request Form 8A certificate.

For renewals, leverage 10% advance payment discount.

For extensions, leverage 6-month flexibility.

For pre-grant opposition risk, monitor publications.
