Rule 19C of the Patents Rules, 2003
Time limit for establishing international search report
Rule 19C fixes the time within which the Indian searching authority must establish the international search report.
Official legal text
The verbatim statutory text of this provision is reproduced from the official source and checked by our legal reviewer before it is published here. 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.
The authority is the enacted text, not this page. Where our wording and the official provision, or an applicable Gazette notification, do not match, the official material prevails.
What this rule requires, step by step
A search report is only useful if it arrives while the applicant can still act on it. Rule 19C therefore puts the searching authority on a clock. The report must be established within three months from the date the authority receives the search copy of the international application, or within nine months from the priority date, whichever of those two periods expires later. The rule mirrors the position under the Treaty Regulations, which are the ultimate source for the international phase.
The two limbs cover two very different situations. Where an applicant files an international application at the end of the twelve month priority year, the nine month limb has already passed by the time the authority sees the file, so the three month limb from receipt of the search copy governs. Where an international application is filed early, or is a first filing with no earlier priority claim, the nine month limb gives the authority more room. Taking whichever expires later means the authority always has a workable minimum period, and the applicant always has an outer date to plan against.
The timing is deliberately keyed to international publication. An international application is published by the International Bureau at eighteen months from the priority date, and the intention is that the search report is ready in time to be published along with it. That helps everyone: the applicant sees the citations with well over a year still to run before national phase decisions, and the public sees, at publication, what the searching examiner thought of the claims.
Applicants have their own part to play in this timetable. The search copy only reaches the authority once the receiving office has processed the application and the search fee has been paid, so a late or short payment delays the start of the clock. If the authority raises an invitation, for example to pay an additional fee where it considers that the application covers more than one invention, or to furnish a sequence listing in the required electronic format, a slow response pushes the report later. The date the report is established also starts the period within which the claims may be amended and the period for demanding international preliminary examination, so a delayed report compresses every later decision.
Finally, treat the outer date as a planning tool rather than a guarantee of an exact day. If a report has not arrived long after the expected window, ask the authority about the status of the file rather than assuming that silence means nothing has happened.
Why this rule matters
Applicants in the international phase and the agents managing their national phase budgets and deadlines.
In the months immediately after the international application is filed and the search fee paid.
A time discipline on the searching authority, and a predictable window in which the applicant will receive the citations.
The applicant plans national phase spending blindly, or loses the short post-report windows for amending claims and demanding preliminary examination.
How it works in practice
A late fee that pushed everything back
Sundara Instruments Pvt Ltd of Madurai filed an international application in the eleventh month of its priority year for a portable water-hardness meter. The transmittal and international filing fees were paid on time, but the search fee was queried by the company's bank and settled only weeks later. Because the search copy could not be sent to the searching authority until the fee was received, the clock for establishing the report started weeks later than the founders had assumed. The report duly arrived within three months of the authority receiving the search copy, exactly as the rule requires, but by then the company had less breathing room than planned before the windows for amending claims and demanding preliminary examination. It still managed both, with a rushed weekend of drafting. The rule had been complied with throughout. What went wrong was the assumption that the clock starts at filing, when in truth it starts when the authority actually receives the file.
Simplified illustration only. Actual legal outcomes depend on the facts.
Key points to remember
- The international search report must be established within three months of the authority receiving the search copy, or nine months from the priority date, whichever expires later.
- The same periods appear in the Treaty Regulations, which govern the international phase.
- The timing is designed so the report can be published with the international publication at eighteen months.
- The clock starts when the authority receives the search copy, which depends on the receiving office and on the search fee being paid.
- Delays in answering invitations from the authority push the report, and every later deadline, further out.
Common mistakes and misunderstandings
- Assuming the period runs from the international filing date. It runs from receipt of the search copy by the authority, or from the priority date on the other limb.
- Paying the search fee late and then being surprised that the report is late.
- Waiting passively for months without checking the status of the file with the authority.
Connected provisions
Every rule traces back to a section. The linked sections are shown apart from the rule because the two are separate instruments, and because a rule that goes beyond its parent section can be challenged. Knowing the parent provision is part of reading the rule properly.
Forms, deadlines and fees
- The international search report must be established within three months from receipt of the search copy by the searching authority, or nine months from the priority date, whichever period expires later.

We do not publish fee amounts. The First Schedule sets them, and they differ by category of applicant, such as a natural person, a startup, a small entity or another applicant, and by the mode of filing.

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 19C
How long does an international search report take?
The rule sets an outer limit rather than a typical time. The authority must establish the report within three months of receiving the search copy, or within nine months of the priority date, whichever expires later. In practice applicants who file late in the priority year usually receive the report within a few months of filing, and those who file early may wait until closer to the nine month point. If nothing has arrived well past that window, ask the authority to confirm the status of your file.
Why is the search report timed to the eighteen month publication?
An international application is published by the International Bureau at eighteen months from the priority date. The search periods are set so that the report is normally ready in time to appear with that publication. That gives the applicant citations to work with long before national phase decisions are due, and gives the public an early indication of how strong the claims look. If the report is not ready in time, the application is published first and the report is published separately afterwards.
What can delay my international search report?
Anything that delays the search copy reaching the authority or the search being completed. Common causes are a search fee that is paid late or short-paid, formal defects that the receiving office has to sort out, an invitation to pay additional fees because the authority considers the application covers more than one invention, and, in biotechnology cases, a missing or non-compliant sequence listing. Answer any invitation from the authority promptly, because the later documents in the international phase are all keyed to the report.
