The Critical Distinction: Rules vs. Act
The 2024 amendments are subordinate legislation made under Section 159 of the Patents Act, 1970. They can soften only those timelines that live in the Rules. Where the Act itself fixes a period and attaches a consequence — "deemed abandoned," "deemed withdrawn," "shall not be entertained" — no Rule, however generously worded, can rescue a defaulting applicant. Only Parliament can change that. This distinction is not academic: it determines which deadlines are now negotiable and which remain absolute.
Key Changes
- Request for Examination (Rule 24B): the window narrows from 48 months to 31 months from the earliest priority date for applications filed on or after the amendment's commencement — a significant acceleration of the prosecution timeline.
- Expanded Rule 138 discretion: the Controller's power to extend time and condone delay is broadened, no longer confined to the narrow set of provisions it previously covered — this is the single most consequential change, converting many previously hard deadlines into ones that can be extended on petition and payment of fee.
- Divisional applications (Rule 13): new sub-rule 13(2A) allows filing further applications in respect of an invention disclosed in a complete or provisional specification, or even based on an already-filed divisional application — clarifying and liberalising divisional practice.
- Grace period (Form 31): where an application is anticipated by public display, provision is made for filing within 12 months of such display.
- Pre-grant opposition (Rule 55): the Controller must now first consider whether a prima facie case is made out before proceeding further — a filtering step intended to curb frivolous oppositions.
- Carve-outs from Rule 137/138 relief: certain provisions remain expressly excluded from the general condonation power — including extension of time under Rule 12(5), specific timelines under Rules 20, 21, 24B, 24C, 55, 80 and 130 — meaning applicants cannot assume every deadline is now flexible.
The Trap: Reading Headlines, Not Fine Print
The liberalised Rule 138 has led some applicants and even practitioners to assume broad extension relief is now available across the board. It is not. The amendment carefully carves out a list of sub-rules — governing matters like Section 8 foreign filing disclosure timelines, examination request deadlines, and certain hearing-related timelines — that remain outside Rule 138's reach. Applicants who miss a genuinely non-extendable deadline on the assumption that "the 2024 amendment fixed all of this" will find no relief available.
Practical Implications
- Audit your docketing system against the specific list of carved-out provisions — do not assume blanket flexibility.
- The compressed 31-month RFE window demands earlier internal decision-making on which applications to pursue to examination.
- Where a deadline is genuinely extendable, act promptly — Rule 138 relief still requires a petition and fee, and is not automatic.
- For anything the Act itself fixes with a stated consequence, treat the deadline as absolute regardless of what the Rules now say.
