Until that check is complete for this page, read the exact wording directly from the official source linked below — it is the only version that governs.
Nothing here replaces the statute. The official wording of the provision, together with any Gazette notification that applies to it, governs. This page only explains that material in ordinary language.
What this section says, in plain language
The Act gives the Controller a great deal of discretion: whether to allow an amendment, whether to accept a divisional application, whether to permit further evidence, whether to grant an extension, whether to refuse an application after examination. Section 80 attaches a condition to all of it. The Controller cannot exercise a discretionary power against an applicant or a party without first giving that person an opportunity of being heard.
This is the natural justice rule written into the statute, and it applies in addition to the specific hearing requirements found elsewhere in the Act. It means an adverse decision cannot come out of nowhere. The party must know what is being held against them and must have a real chance to answer it, in writing and, if they ask, at a hearing.
Rule 129 sets the procedure. Before exercising discretion adversely, the Controller gives the party notice, and the party must indicate whether they wish to be heard. If you do not respond, the Controller may proceed. Rule 129A deals with adjournments, requiring a request with reasonable cause made in advance and limiting how many adjournments a party may get, which stops hearings from being pushed indefinitely.
Failure to comply is a strong appeal point. An order that refuses an application on a ground never put to the applicant, or that rejects an amendment without a hearing when one was sought, is vulnerable on appeal to the High Court under section 117A, and courts have sent such matters back for a fresh hearing. That said, section 80 gives a right to be heard, not a right to win; a hearing properly given and a reasoned order that goes against you is not a breach of this section.
Why this section matters
Every applicant facing refusal, every patentee facing an adverse order, and every party to opposition and licensing proceedings.
Any time the Controller is about to decide something discretionary against you, most often at the end of examination or in a contested matter.
A statutory right to notice and a hearing before an adverse exercise of discretion, and a corresponding duty on the Controller.
If you ignore a hearing notice, the Controller can decide without you; if the Controller ignores the section, the order is open to challenge on appeal.
How it works in practice
A refusal on a ground never put to the applicant
Sahyadri Water Systems Pvt Ltd, Kolhapur, receives a first examination report objecting to its rainwater filter application on inventive step and clarity. It files a detailed reply with amended claims, and a hearing is held on those two issues. Weeks later an order arrives refusing the application, not on inventive step, but on the ground that the amended claims go beyond the original disclosure - a point never raised in the report, never mentioned in the hearing notice, and never argued at the hearing. Sahyadri appeals to the High Court under section 117A, relying on section 80. The company does not ask the court to grant the patent. It asks for the order to be set aside because it never had a chance to answer the ground on which it lost. The court agrees, sets aside the refusal and sends the matter back for a fresh hearing at which the disclosure objection can be put to the company and answered.

Key points to remember
- The Controller must give a hearing before exercising discretion against a party.
- The right applies over and above the specific hearing provisions elsewhere in the Act.
- Rule 129 requires prior notice, and you must say whether you want to be heard.
- Rule 129A controls adjournments, which must be requested in advance with reasons.
- Deciding against a party on a ground never put to them is a strong ground of appeal.
- The section guarantees a fair process, not a favourable outcome.
Common mistakes and misunderstandings
- Ignoring a hearing notice because the objections look weak. Silence lets the Controller decide without your answer.
- Assuming a hearing must be in person. Hearings are commonly held by video conference, and attending remotely is attending.
- Thinking a reasoned adverse order breaches this section. What matters is whether you were told the case and given the chance to meet it.
Connected provisions
The rules connected to a section are listed on their own because they are subordinate legislation. They cannot go beyond the Act, but they can be changed by notification without a new statute, so seeing them separately makes it easier to check whether the current procedure is still what you remember.
Forms, deadlines and fees
- The hearing notice fixes the date of the hearing and the date by which you must confirm attendance - both are stated in the notice and must be met.
- Written submissions after a hearing must be filed within the period the Rules allow, so confirm that period at the hearing itself.
Open the deadline calculator — and have every date confirmed against the current Rules before you rely on it.
Any official fee connected with this provision is fixed by the First Schedule to the Patents Rules, not by the provision itself. The amount depends on who the applicant is and on whether the filing is made online or on paper, so no figures are reproduced here. How Indian patent fees work.

Questions people ask about Section 80
Do I have to ask for a hearing, or is one given automatically?
You generally have to ask. Under the procedure in the Rules, the Controller gives notice before deciding adversely, and the party is expected to state whether they wish to be heard. If you do not respond, the Controller can proceed on the material on record. So treat every notice as requiring a positive reply, even if you only intend to rely on your written submissions, and keep proof of the response.
Can I file written submissions after the hearing?
Yes, written submissions summarising what was argued are routinely filed after a hearing, and the Rules set the period for doing so. Use them to record the amendments offered, the concessions made and the authorities relied on, because the order will usually be written from the file. Do not use them to introduce entirely new arguments that were never made at the hearing, since that can attract an objection.
What if I cannot attend on the date fixed?
Apply for an adjournment in advance, with a genuine reason, following the procedure in the Rules. Adjournments are limited in number and are not granted for convenience, so do not assume one will be given. If your representative cannot attend, arranging a substitute who is properly briefed is usually a better plan than a last minute request. Simply not appearing is the worst option, because the Controller can then decide on the papers alone and you lose the chance to answer the objections.
Does this section apply in opposition proceedings?
Yes, and it applies to both sides. Opposition has its own hearing provisions, but the general obligation not to exercise discretion adversely without a hearing runs through the whole Act. So a decision to refuse further evidence, to shut out a late filing or to decide a preliminary point should not be taken without giving the affected party a chance to be heard on it.
