Rule 19B of the Patents Rules, 2003
International search report
Rule 19B requires the Indian searching authority to draw up an international search report, or explain why none can be made.

What this rule requires, step by step
Once an international application reaches the Indian office in its capacity as an International Searching Authority, Rule 19B governs the output. The authority must establish an international search report in the manner the Treaty and its Regulations require. Alongside it, a written opinion is prepared on whether the claimed invention appears to be new, to involve an inventive step and to be capable of industrial application. Together these two documents are the applicant's first serious external assessment of the invention.
The search report itself is a list, not an essay. It identifies the documents found, gives the classification of the subject matter, indicates which fields were searched, and marks each citation with a category. A document marked as particularly relevant on its own goes into one category; one that matters only when combined with another document goes into a second; general background material goes into a third. Reading those categories properly tells an applicant a great deal. A single strongly relevant citation against the independent claim is a warning. A page of background citations usually is not.
Sometimes no meaningful search is possible. The Treaty allows the authority to declare that no international search report will be established, for example where the subject matter is of a kind the authority is not required to search, or where the description, claims or drawings are so unclear that no useful search can be carried out. Rule 19B covers that outcome too. A declaration of that sort is a serious signal: it usually means the claims need rewriting before any national office will engage with them.
The written opinion is where the reasoning lives. It goes claim by claim, says whether each appears to satisfy the three tests, and explains why, referring to the cited documents. It may also note defects in form, unity of invention problems where the application really covers more than one invention, and clarity issues. Nothing in it binds any national office, and the Indian Controller will examine the case again if the national phase is entered. But it is written by an examiner who has actually searched the art, and applicants who dismiss it usually meet the same objections later at greater cost.
What you do next matters. The Treaty allows the claims to be amended once after receiving the search report, within a period measured from the transmittal of the report or from the priority date, and there is also the option of asking for international preliminary examination so that arguments and amendments can be considered. Both routes are time-bound, so the search report should be read the week it arrives, not the month before national phase entry.
Why this rule matters
Every applicant whose international application is searched by the Indian authority, and anyone deciding which countries are worth the cost of national filing.
In the international phase, typically several months after filing and well before the national phase deadlines.
An obligation on the authority to produce a search report and written opinion, or a reasoned declaration that no report can be established.
The applicant spends money on national phase entries that the citations had already doomed, and loses the chance to amend claims while it is still cheap.
How it works in practice
Reading the categories, not just the count
Harish Patel, a founder in Surat, received the international search report for his application on a modular solar dryer and panicked at the sight of eleven citations. His agent walked him through the categories. Nine were background material of the general kind that appears in almost every report. One was relevant only if combined with another document. Just one was marked as damaging on its own, and it disclosed the frame geometry that formed the whole of his broadest claim. The written opinion said as much in two paragraphs. Harish had a real choice to make within a short window: keep a broad claim that an examiner had already told him was not new, or amend to the humidity-triggered vent arrangement described in his examples, which no citation showed. He amended, narrowed the independent claim, and entered the national phase in two countries. The report did not destroy his case. It told him which case he actually had.

Key points to remember
- The searching authority must produce an international search report, or declare that no report will be established.
- A written opinion accompanies the report and addresses novelty, inventive step and industrial application claim by claim.
- Citations are categorised, and the category tells you how dangerous a document is.
- A declaration that no search is possible usually points to unclear claims or excluded subject matter.
- Neither the report nor the opinion binds any national office, including the Indian Controller.
- There are time-limited opportunities to amend the claims after the report arrives, so read it immediately.
Common mistakes and misunderstandings
- Judging the report by the number of citations rather than by their categories and which claims they hit.
- Assuming the written opinion is a rejection. It is an opinion, and it can be answered with arguments or amendments.
- Filing the report away until the national phase deadline, by which time the least costly chances to amend have gone.

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 claims of an international application may be amended once after the search report is transmitted, within the period fixed by the Treaty Regulations, which runs from transmittal of the report or from the priority date, whichever expires later. Check the current PCT Regulations for the exact period before relying on it.

Fees are prescribed in the First Schedule to the Patents Rules. Because the Schedule is revised from time to time, and charges different amounts to different categories of applicant and for physical as against electronic filing, this page describes the fee without stating a figure.

Questions people ask about Rule 19B
What is in an international search report?
A list of the documents the examiner found that may affect your invention, with the classification of your subject matter and the fields and databases searched. Each citation is placed in a category showing whether it is damaging on its own, damaging only in combination with another document, or simply background. The report is accompanied by a written opinion which explains, claim by claim, whether the invention appears to be new, inventive and industrially applicable, and why.
What does it mean if no international search report is established?
The Treaty allows the authority to declare that no report will be made, usually because the subject matter falls outside what it must search, or because the claims and description are so unclear that no meaningful search is possible. Take it seriously. It generally means the application needs substantial redrafting of the claims before any national office will be able to examine it properly, and it leaves you entering national phases without the usual guidance on prior art.
Can I amend my claims after the international search report?
Yes. The Treaty gives one opportunity to amend the claims after the search report is transmitted, within a period fixed by its Regulations, and a fuller opportunity to amend the description, claims and drawings if you demand international preliminary examination. Amendments in the international phase cannot add matter beyond what was disclosed in the application as filed. You can also wait and amend during the national phase in each country, but that means paying to file claims you already know are weak.
Is the written opinion the same as a rejection?
No. It is the searching examiner's reasoned view, prepared without hearing from you. It has no legal effect on any application and grants or refuses nothing. Its value is predictive: objections raised there tend to reappear in national examination, so answering them early saves money. In India the Controller conducts an independent examination under Sections 12 and 13 and can reach a different conclusion, favourable or unfavourable, from the international authority.
