Rule 61 of the Patents Rules, 2003
Copies of documents to be supplied
Rule 61 requires documents relied on in an opposition to be supplied in authenticated copies, with English translations where needed.
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.
This explanation is written for clarity, not for citation. The official statutory text and any Gazette notification in force on your date govern, and they prevail over anything said here.
What this rule requires, step by step
An opposition is only as good as the documents behind it, and those documents have to be in front of everyone who has to read them. Rule 61 covers that housekeeping. Where a notice of opposition, a written statement or any evidence refers to a document, copies of that document must be furnished as required, so that the other party, the Opposition Board and the Controller all work from the same material. Copies are generally supplied in duplicate unless the Controller directs otherwise, and they must be authenticated to the Controller's satisfaction.
Language is dealt with squarely. Where a specification or other document relied on is in a language other than English, a translation into English must be supplied, verified or attested as required. Indian oppositions frequently turn on Japanese, German, Chinese, French or Korean publications, and an untranslated document proves nothing. The translation should cover the parts relied on properly and should not be a selective extract that changes the sense of the original.
Authentication matters because dates matter. In a novelty or obviousness case the question is not only what a document says but when the public could get it. A clean copy showing the journal title, volume, issue and date, or a library stamp, a publisher's certificate or a database record, does more work than a blurred photocopy. Where the document is a patent specification from another country, the official copy with its publication date is the natural choice.
The rule looks administrative, and it is, but failures here cost real cases. If a document reaches the Board without a translation, the Board cannot rely on what the party says it means. If a copy is illegible, the point may be treated as unproved. If copies are not served on the other side, the Controller may allow time to answer, delaying the hearing. Preparing the document bundle carefully at the outset, with an index, dates and translations, is one of the least expensive ways to strengthen an opposition.
Why this rule matters
Opponents and patentees in post-grant opposition, and anyone relying on foreign language or hard to obtain documents.
At every stage where documents are referred to, from the written statement through the evidence rounds to the hearing.
A duty to place authenticated copies, and English translations where needed, on the record and with the other party.
Documents that are untranslated, unauthenticated or not served may carry little or no weight when the Board and the Controller assess the grounds.
How it works in practice
A German publication that finally proved its date
Bhavnagar Marine Coatings opposes a granted patent on an anti-fouling coating, relying mainly on a German trade journal article. Its first bundle contains a photocopy of two pages with a handwritten year in the margin and a short summary of the article prepared by an in-house chemist. The patentee objects that the date is unproved and that the summary is not a translation. Rather than argue, the opponent's agent fixes the file. The company obtains a clean copy of the full article from a university library in Germany, with the issue cover page showing volume, number and month, and a stamped library receipt record. A qualified translator prepares a full English translation with a signed statement of accuracy, and the translation is filed with the original text side by side. Copies go to the patentee and to the office as required. At the hearing the date and content are no longer in dispute, and the argument moves to the only question that matters, whether the article makes the claimed coating obvious.

Key points to remember
- Copies of documents referred to in an opposition must be supplied as required, normally in duplicate.
- Copies must be authenticated to the satisfaction of the Controller.
- Documents not in English need a proper English translation, verified or attested as required.
- Prove publication dates with cover pages, library records, publisher confirmations or official patent copies.
- The other party must receive the same documents so it can respond.
- A clear, indexed, dated bundle makes the Opposition Board's work easier and your case stronger.
Common mistakes and misunderstandings
- Filing a summary of a foreign document instead of a translation. A summary written by a party is argument, not evidence.
- Relying on an undated internet printout. Without proof of when the material was publicly available, it may prove nothing.
- Sending documents to the office but not to the other side, which invites an adjournment application.
- Filing partial extracts that leave out passages qualifying the sentence relied on, which damages credibility badly.
- Assuming a poor photocopy will do. If the Board cannot read it, the point is effectively not made.
Connected provisions
Because this page covers a rule rather than a section, the related Act provisions are shown in their own list. The section tells you what the law requires. The rule, explained above, tells you how the Patent Office expects that requirement to be met.
Forms, deadlines and fees
- Copies are to be furnished along with the document that refers to them, or as the Controller directs.

Any official fee connected with this provision is fixed by the First Schedule to the Patents Rules, not by the provision itself. The amount depends on who the applicant is and on whether the filing is made online or on paper, so no figures are reproduced here. How Indian patent fees work.
Related judgments
Case summaries are published only after a qualified reviewer has checked the judgment, the citation and the way the holding is described. Nothing has cleared that review for this provision yet, so nothing is listed here. We would rather show no case note than one that misstates what a court decided. How case notes are prepared.
Questions people ask about Rule 61
Do I need to translate foreign language prior art in an Indian opposition?
Yes. If you rely on a document that is not in English, you must supply an English translation, verified or attested as required, along with the original. Use a competent translator and translate the whole of the relevant document rather than a convenient paragraph, because the patentee may point to surrounding text that changes the meaning. Attach a signed statement of accuracy. An untranslated document effectively cannot be relied on, however good it is.
How do I prove when a document was published?
Use the best evidence available. For a journal, file the cover page with volume, issue and date, and if possible a library accession stamp or catalogue record. For a book, use the imprint page. For an official patent publication, use the official copy showing the publication date. For a website, a dated archive record and an affidavit from the person who retrieved it are far stronger than a plain printout. Publication date is often the point on which prior art cases are won or lost.
How many copies of documents should be filed?
The rule contemplates copies being furnished in duplicate unless the Controller directs otherwise, and a copy must also reach the other party. In practice, prepare a clean indexed set for the office, a set for service on the other side, and keep a matching set for the hearing. Number the pages of the whole bundle continuously and refer to those numbers in your written statement and affidavits, so that everyone can find a passage instantly.
