Rule 32 of the Patents Rules, 2003
Procedure in case of potential infringement
Sets the procedure the Controller follows when a pending claim looks likely to infringe a claim of another patent already in force.

What this rule requires, step by step
Novelty is not the only thing examination looks at. Sometimes a pending application is perfectly new, yet working the invention as claimed would run into a patent that somebody else already holds. A classic case is an improvement: your device is better than the one already patented, but it still contains every feature of the earlier claim. The Act gives the Controller a way to flag that situation, and Rule 32 supplies the procedure for handling it.
The rule does not invent a fresh process. It borrows the machinery already used when an application is objected to on the ground of an earlier disclosure. The applicant is told what the problem is and which patent is involved, is given time to reply, may file evidence, may amend the specification, and may ask to be heard before any direction is made. The Controller does not act on the examiner's view alone, and the applicant is never expected to answer an objection without knowing what it rests on.
The applicant has three realistic answers. The first is to argue that the claim as drafted does not in fact fall within the other patent's claim. The second is to amend, so that the claims are limited to the part of the invention that sits outside the earlier right. The third is to say that the other patent's claim is invalid, which is a heavier argument and needs material to support it. If none of these succeeds, the Controller may direct that a reference to that other patent be printed in the applicant's specification as a warning to the public.
The important practical point is that this procedure decides nothing about infringement. The Controller is not a court and is not ruling that you would be sued or that you would lose. Getting your own patent has never meant you are free to work your invention; if your product uses somebody else's protected feature, you still need their licence. This procedure simply makes that risk visible on the public record instead of leaving it for a buyer or investor to discover later.
Why this rule matters
Applicants filing improvements on technology that others have already patented in India, and their licensees and investors.
During examination of the complete specification, when the search shows a patent in force whose claim appears to cover the claimed subject matter.
A structured chance to answer, amend or contest before the Controller directs that a reference to the other patent be inserted.
The application can stall, a permanent public warning can be printed on your specification, and the underlying licensing problem stays unsolved.
How it works in practice
An improvement that still needed a licence
Kestrel Robotics Pvt Ltd of Hyderabad applied for a patent on a warehouse robot with a self-levelling tray. During examination, the office pointed to a patent in force held by a Chennai company covering a mobile robot with the exact drive and sensing arrangement Kestrel had claimed as part of its combination. Kestrel's claim was new, because nobody had described the self-levelling tray, but working the claim would have used the Chennai company's protected arrangement. Kestrel was told about the objection and asked to respond. Its agent filed a written reply, attended a hearing, and then amended the independent claim so that it was tied to the tray mechanism and its control loop rather than to the whole vehicle. That satisfied the Controller and no reference was printed. Separately, Kestrel's commercial team opened licensing talks with the Chennai company, because the amendment fixed the claim scope, not the freedom to sell the finished robot.

Key points to remember
- The situation covered here is potential infringement of another live patent, not lack of novelty.
- The procedure reuses the hearing and reply machinery already used for earlier-disclosure objections.
- The applicant may reply, file evidence, amend the claims, ask to be heard, or challenge the other claim's validity.
- The outcome can be a printed reference to the other patent inside the applicant's own specification.
- Nothing decided here settles an infringement dispute; only a court can do that.
Common mistakes and misunderstandings
- Believing that a granted patent is a licence to operate. It lets you stop others; it does not remove someone else's earlier right over a feature you use.
- Ignoring the objection because the other patent looks weak. Attacking validity in this forum needs real evidence, and a bare assertion will not be enough.
- Waiting until after grant to start licensing talks. The examination objection is usually the first written warning you get, and it is cheaper to act on it early.
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
- A reply to this kind of objection must be filed within the period the Controller allows, and the application must still be put in order for grant within the overall period fixed by the Act and Rules. Confirm both against the current Rules.

Related judgments
No judgment summaries appear here yet. Our process requires a legal review of each case note before publication, covering the citation, the court and the point actually decided. Until a note for this provision has passed that check, the section stays empty rather than carrying unverified material. How case notes are prepared.
Questions people ask about Rule 32
What is potential infringement in Indian patent examination?
It describes a pending application whose claims, if worked, would fall within a claim of a patent that is already in force in India. The application may be entirely new, so novelty is not the problem. The concern is overlap with someone else's live right. The Controller can raise it during examination, hear the applicant, and in the end direct that a reference to that other patent be printed in the applicant's specification as a warning to readers.
Can I still get a patent if my invention infringes another patent?
Yes, in principle. Patentability and freedom to operate are separate questions. An improvement can be new, inventive and industrially applicable, and therefore patentable, while still using a feature covered by an earlier patent. You would then need a licence from the earlier patent holder to sell the product. Indian law also has a route for a compulsory licence between dependent patents in narrow circumstances, but a negotiated licence is the normal answer.
How should I respond to an objection about another patent in force?
Start by mapping your independent claim against the claim being cited, feature by feature. If a feature is genuinely absent, say so with reasons. If it is present, consider amending so your claim is anchored to what is truly yours. Use the hearing if one is offered, because a short discussion often narrows the issue. In parallel, take commercial advice on whether a licence from the other patent holder is needed.
