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 rule requires, step by step
Directions under section 51 can be commercially decisive. They can allow a licence that one co-owner opposes, settle how income from a patent is divided, or authorise someone else to sign a document in a proprietor's name. Because the effect is that serious, the Act and the Rules insist that nobody is affected without being heard. Rule 78 is the procedure that makes that guarantee real.
The sequence is predictable. An application under Rule 76 or Rule 77 is filed. The Controller sends a copy to every other person shown by the register as a proprietor, and to anyone else who appears to be affected. Those parties may put in a statement of their case with documents. The Controller then gives notice of a hearing, at which the parties or their registered patent agents appear, and afterwards passes a reasoned order setting out the directions given, if any.
Preparation decides these matters. The Controller is weighing commercial fairness between people who each own a share, so the useful material is documentary: the joint ownership or research agreement, the correspondence in which the proposal was made and refused, the terms actually on the table, evidence of what the patent could earn, and the record of renewal payments. A party who has behaved reasonably and can show it, in writing and with dates, starts from a strong position.
Two things bound the exercise. The Controller respects an agreement already in force between the co-owners rather than overriding it, so a party relying on such an agreement should place it on record at the first opportunity. And the order is not final in the sense of being unchallengeable: decisions of the Controller under section 51 are among those that can be appealed to the High Court under section 117A, following the abolition of the Intellectual Property Appellate Board by the Tribunals Reforms Act, 2021.
Why this rule matters
Every co-owner of an Indian patent involved in a section 51 application, whether they applied or are answering one.
From the moment an application under section 51 is filed until the Controller passes the final order.
A right to notice, to file a statement, and to be heard before any direction affecting a co-owner's interest is given.
A co-owner who does not respond or attend allows directions to be shaped entirely by the other side's account of the facts.
How it works in practice
Preparing for a co-ownership hearing
A design studio in Jaipur and a plastics moulder in Vadodara jointly own a patent for a stackable water tank fitting. The moulder applies to the Controller for directions permitting it to grant a licence to a third manufacturer. The studio receives a copy of the application and, instead of writing an angry letter, files a proper statement. It attaches the joint ownership agreement signed when the patent was filed, which says that neither party may licence a competing manufacturer for the first five years, the email chain showing that it had offered an alternative arrangement, and its record of having paid the last two renewal fees alone. At the hearing both sides appear through their patent agents. The Controller finds that the agreement covers the exact situation and declines to give a direction that would cut across it, while recording the studio's willingness to reconsider after the agreed period. The moulder now knows precisely what it must renegotiate, and both parties know where they stand.
Simplified illustration only. Actual legal outcomes depend on the facts.
Key points to remember
- Every affected proprietor gets a copy of the application and a chance to reply.
- Statements should be filed with the documents relied on, not held back for the hearing.
- Hearings may be attended in person or through a registered patent agent, and are commonly held by video conference.
- The Controller respects an existing agreement between the co-owners, so put it on record early.
- The order is reasoned, and an appeal lies to the High Court under section 117A.
Common mistakes and misunderstandings
- Ignoring the Controller's notice in the belief that owning a share is protection enough. Directions can be given in your absence.
- Arguing about breach of contract and damages. Those claims belong before a civil court; the Controller is deciding how the patent is dealt with.
- Producing the joint ownership agreement for the first time at the hearing, when the other side has had no chance to answer it.
Connected provisions
The link between a rule and its section matters in practice, because an argument about whether a procedure is valid usually starts with the parent provision. The connected sections are listed here, apart from the explanation, so the chain of authority is easy to follow.
Forms, deadlines and fees
- The Controller fixes the time for filing statements and gives notice of the hearing date; note both immediately, because extensions are discretionary.

Where a fee is payable under this provision, the figure comes from the First Schedule. Categories of applicant are charged at different rates, and electronic filing is treated differently from paper filing, so an accurate number can only come from the Schedule in force on the day you file.

Questions people ask about Rule 78
Will I be heard before directions are given about my patent share?
Yes. Rule 78 requires the Controller to give notice to every proprietor and anyone else affected by an application under section 51, and to give them an opportunity to be heard before any direction is made. You may file a written statement with your documents and then appear at the hearing yourself or through a registered patent agent. Hearings before the Controller are commonly conducted by video conference, so distance is rarely a barrier. What you cannot do is stay silent and expect the application to fail on its own.
What should a co-owner file in reply to a section 51 application?
A short, dated narrative supported by documents. The most valuable items are any joint ownership, research or shareholders agreement covering how the patent is to be licensed, the correspondence showing what was proposed and what you said in response, the actual terms of any deal on the table, evidence about the market and what the patent can earn, and the record of who has been paying the renewal fees. File everything with the statement rather than saving it for the hearing, so that it forms part of the record the Controller and, if necessary, an appellate court will read.
Can I appeal an order made under section 51?
Yes. Section 117A lists the decisions of the Controller that can be taken in appeal, and section 51 is among them. Since the Tribunals Reforms Act, 2021 abolished the Intellectual Property Appellate Board, such appeals go to the High Court with jurisdiction. Appeals have their own limitation period, so act quickly once the order is received. Because an appellate court works mainly from the material already placed before the Controller, the strength of your appeal is largely determined by how well you presented your case at the hearing stage.
