Section 117A Patent Appeals After the IPAB

Explainer · Patent Appeals · Last verified October 2026

Updated for 2026 · Claw Editorial

A Controller of Patents has refused your application, or revoked a grant, or ruled against you in a pre-grant opposition, and the clock has started. The one rule to remember: an appeal against a Controller decision under Section 117A of the Patents Act, 1970 must be filed in the High Court within three months from the date of the decision, unless the High Court allows more time. This page explains who can appeal, where to file, what to attach, and how to track the matter so the deadline is never missed. Last verified October 2026.

01The problem: a decision and a ticking clock

Before April 2021, a person unhappy with a Controller’s order went to the Intellectual Property Appellate Board (IPAB). That board was abolished under the Tribunals Reforms Act, 2021, and its patent appeals moved to the High Courts. Many applicants, agents and in-house teams still carry the old habit of looking for the IPAB, and that is where mistakes begin.

Old habits cause late filings

A refusal order from the Patent Office is dated, and the appeal period runs from that date, not from the day the order reached your inbox or your agent. If a team spends weeks working out the right forum, a large part of the window is already gone.

Many kinds of orders can be appealed

Section 117A covers a long list of Controller decisions: refusals, pre-grant and post-grant opposition outcomes, restoration, amendment and others. Each looks different on paper, but the same three-month rule applies. Knowing that the rule is common helps you act fast.

The cost of missing the window

A late appeal needs the High Court to allow extra time, and that is never guaranteed. For a patent worth protecting, the safe plan is to treat the three months as a hard deadline from day one.

02What Section 117A says

Section 117A of the Patents Act, 1970 gives a right of appeal to the High Court against specified decisions, orders and directions of the Controller or the Central Government. It lists the sections under which such decisions can be appealed. These include Sections 15, 16, 17, 18, 19 and 20, Section 25(4), Sections 28, 51, 54, 57, 60, 61, 63 and 66, Section 69(3), Sections 78, 84(1) to (5), 85, 88, 91, 92 and 94.

In plain terms, that means most of the Controller’s important decisions on grant, refusal, opposition, amendment, restoration and licences can be taken to the High Court.

The section also says three things about the appeal itself. It must be in the prescribed form and verified as prescribed. It must come with a copy of the decision appealed against. And it must carry the prescribed fee.

Under Section 117A, an appeal against a Controller of Patents decision lies to the High Court and must be made within three months from the date of the decision, order or direction.

03The three-month window

The appeal period under Section 117A is three months from the date of the decision, order or direction of the Controller or the Central Government. The High Court can allow further time, in line with its own rules, but you should not plan on it.

Count from the date of the order

The safe method is to count three calendar months from the date printed on the order. Put the last date in your docket on the day the order is received, and set earlier reminders at one month and two months.

Extension is discretionary

The High Court may allow more time if you show good reason. Courts decide this case by case, so an extension is a request, not a right.

Do not wait for a certified copy

Filing early and supplying the order later, where the court rules allow it, is better than losing days chasing paperwork.

04Which High Court, and how to file

An appeal under Section 117A goes to the High Court that has territorial jurisdiction over the Patent Office where the application was filed, as the Delhi High Court has discussed in its judgments after the IPAB was dissolved. The Patent Office has branches in Delhi, Mumbai, Chennai and Kolkata, so the right High Court usually follows the appropriate office on your application.

The IP Division in Delhi

The Delhi High Court has an Intellectual Property Rights Division. Matters are filed under case-type codes, and a patent appeal against the Controller is listed under the code C.A.(COMM.IPD-PAT). A patent revocation petition filed as an original proceeding uses C.O.(COMM.IPD-PAT). Read the Division’s own rules before filing, because they set out filing format, pagination and listing practice.

Form and fee

The Patents Rules prescribe the form of appeal and the fee. Check the current Patents Rules and the High Court fee schedule on the day you file.

What to attach

• The Controller’s order, with its date clearly shown.
• The grounds of appeal, stated as points of fact and law.
• The patent or application details, including the application number.
• The prior filings and hearing notices that the order relies on.

05A practical checklist

A short checklist keeps an appeal on time. Use it from the day the order arrives.

This is general information and not legal advice. Instruct a patent litigation advocate for any actual appeal.

06Tracking an appeal once it is filed

Filing is only the start. A patent appeal in the High Court has its own listing dates, orders and cause lists. Teams that keep these in an email folder or a spreadsheet tend to miss a listing or a compliance direction.

Two other things need watching. The first is the Patent Office side: pending hearings, annuity dates and response deadlines on the same patent family. The second is the court side: the High Court IP Division’s orders and cause lists. Keeping both in one view reduces the risk of a clash between the two.

Where your needs go beyond India, such as global annuity payment across many countries, specialist tools like Anaqua, Clarivate and Dennemeyer are built for that. For very high-volume docketing inside IP firms, Iolite and JSK are specialist options. For prior-art and patent landscape search, PatSnap, Questel and IPRally are stronger than a general platform.
