Rule 19J of the Patents Rules, 2003
Processing of demands for international preliminary examination
Rule 19J requires the Indian examining authority to process a demand as the Treaty directs, including opinions and the applicant's right to reply.

What this rule requires, step by step
Once a demand has been filed and the fees paid, someone has to do the work. Rule 19J is the provision under which the Indian Patent Office, acting as an International Preliminary Examining Authority, processes demands in the manner laid down by the Treaty and its Regulations. It is the engine room rule of Chapter II: it does not create new Indian requirements so much as commit the office to running the international procedure properly.
Processing starts with checks. The authority confirms that it is competent for the application, that the applicant is entitled to make a demand, that the demand is in order, and that the fees have been paid. If something is missing, an invitation to correct it is issued with a short period to respond. The examination itself then begins at the time fixed by the Treaty Regulations, and is carried out on the description, claims and drawings as amended, if amendments have been filed.
The heart of the process is the exchange of views. Where the examiner considers that a claim lacks novelty, lacks an inventive step or is not industrially applicable, or that the application has defects of form or clarity, a written opinion is issued setting out the reasons and giving the applicant a period to reply. The applicant may answer with arguments, with amendments under Article 34, or with both. Amendments must stay within the disclosure of the application as filed; nothing new can be introduced at this stage. Contact with the examiner, including by telephone or a short interview, is contemplated by the Treaty machinery, which makes this stage far more useful than the one-sided written opinion that accompanied the search report.
Two recurring issues deserve mention. The first is unity of invention. If the examiner considers that the application really covers more than one invention, the applicant may be invited to pay additional fees or to restrict the claims, and any claims not covered by payment or restriction may go unexamined. The second is excluded subject matter. Certain categories, such as methods of treatment of the human body, are ones on which the authority is not required to give an opinion. Where they arise, the report will say why no opinion was given rather than pronounce on patentability.
It is worth remembering what is not happening here. The authority is not granting anything and is not applying Indian law. Section 3 of the Patents Act, which lists what is not an invention in India, is not being applied at this stage. When the application reaches the Indian national phase it is examined again under Sections 12 and 13 within the framework of Rule 24B, and objections that never surfaced internationally can appear there for the first time.
Why this rule matters
Applicants who have demanded international preliminary examination in India, and the agents who reply to the written opinions issued during it.
Between the filing of the demand and the issue of the international preliminary examination report.
A duty on the Indian authority to process demands under Treaty procedure, and a real right for the applicant to be heard through replies and amendments.
A written opinion left unanswered results in a negative report on the original claims, which then follows the application into every national phase.
How it works in practice
Answering the opinion instead of ignoring it
Ranganath Bio Pvt Ltd of Mysuru demanded preliminary examination on an enzymatic process for treating textile effluent. The examiner issued a written opinion saying claim 1 was obvious over a Japanese publication combined with a general textbook, and that claims 8 to 12, drafted as a method of treating a patient, fell in a category on which no opinion would be given. The company had a month-long internal debate about whether replying was worth the cost. Its agent argued that a negative report would travel with the file into every country, and that a reply cost far less than five separate national arguments. Ranganath replied with data showing that the cited combination produced only a fraction of the enzyme yield, and deleted the method-of-treatment claims, recasting them as process claims. The final report accepted inventive step for the amended claims. Three national examiners later cited that reasoning, and the Indian Controller's report raised no objection on inventive step at all.

Key points to remember
- The authority checks competence, entitlement, formalities and fees before examination starts.
- Examination is carried out on the application as amended, where amendments have been filed.
- A written opinion sets out objections with reasons and gives the applicant a period to reply.
- The applicant may respond with arguments and with amendments under Article 34, which cannot add new matter.
- Unity of invention objections may require additional fees or restriction of the claims.
- Some subject matter is outside what the authority must examine, and the report will say so.
- Nothing here applies Indian law; national phase examination in India happens separately.
Common mistakes and misunderstandings
- Treating a written opinion in Chapter II as final. It is an invitation to reply, and replies frequently change the outcome.
- Filing amendments that introduce matter not in the application as filed, which the examiner cannot take into account.
- Expecting an opinion on every claim. Claims in excluded categories, or not covered when additional unity fees were requested, may go unexamined.
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 written opinion issued during international preliminary examination must be answered within the period stated in it; the period is short, so do not wait for a reminder.

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.

Related judgments
Case law is added slowly and deliberately. A summary is drafted, checked against the reported judgment and then reviewed before publication, because a wrong case note can mislead a reader badly. No summary for this provision has reached publication yet. How case notes are prepared.
Questions people ask about Rule 19J
What happens after I file a PCT demand?
The authority checks that it is competent, that the demand is in order and that the fees are paid, then begins examination at the time set under the Treaty Regulations, working from your claims as amended. If the examiner has objections you receive a written opinion with reasons and a period to reply. You can answer with arguments, with amendments, or with both, and there is scope for informal contact with the examiner. The process ends with the international preliminary examination report.
Can I talk to the examiner during international preliminary examination?
The Treaty machinery contemplates contact between the applicant and the examiner during this stage, including by telephone or a short interview, which is one of the practical advantages of Chapter II over the search stage. What is discussed should be confirmed in writing on the file, because the report will be based on the record. Do not rely on an oral understanding: if an amendment or an argument matters, put it on the file in the reply.
What if the examiner says my application covers more than one invention?
That is a unity of invention objection. You may be invited to pay additional fees so that the extra inventions can be examined, or to restrict the claims to one invention. If you do neither, the claims left outside may simply not be examined, and the report will record that. Neither outcome destroys the other inventions: they can be pursued through separate national filings or divisional applications under the national law of each country, subject to that country's rules.
