Chapter 6 : The Patent Act,1970

CHAPTER VI: ANTICIPATION

This chapter defines what “Anticipation” (i.e., not being new) means and, more importantly, what it doesn’t mean. These sections are “grace provisions” that can save an application from being rejected for prior art.

Section 29: Anticipation by previous publication

• (1) What it says: An invention… shall not be deemed to have been anticipated by reason only that the invention was published in a specification… dated before the 1st day of January, 1912.
  • In plain English: This is a historical, “house-keeping” rule. When an examiner searches for “prior art” to see if your invention is new, they are not allowed to use any old Indian patent specifications published before 1912.
• (2) What it says: …an invention… shall not be deemed to have been anticipated by reason only that the invention was published before the priority date… if the patentee or the applicant… proves —
  • In plain English: Your application can be saved even if the invention was published before your priority date, if you can prove the publication was a leak or betrayal.
• (a) What it says: that the matter published was obtained from him… and was published without his consent…; and
  • In plain English: You must prove that someone stole the information from you (or you told them in confidence) and they published it without your permission.
• (b) What it says: where the patentee… learned of the publication before the date of the application… that the application… was made as soon as reasonably practicable thereafter:
  • In plain English: You must also prove that as soon as you found out about the leak, you rushed to the Patent Office to file your application.
  • Real-world example:
    1. On Jan 1, you show your new invention to a journalist “off the record.”
    2. On Jan 15, the journalist breaks the agreement and publishes an article about it.
    3. You see the article on Jan 16 and immediately file your patent application that same day.
    4. The Controller cannot use that Jan 15 article to reject your patent, because you can prove it was a non-consensual leak (a) and you acted immediately (b).
• Proviso: Provided that this sub-section shall not apply if the invention was before the priority date commercially worked in India…
  • In plain English: This “leak” exception does not work if your invention was already being bought and sold in India (unless it was just for a test or trial). You can’t claim a “leak” for something that’s already on the market.

Section 30: Anticipation by previous communication to Government

• What it says: An invention… shall not be deemed to have been anticipated by reason only of the communication of the invention to the Government… or of anything done, in consequence… for the purpose of the investigation.
  • In plain English: Disclosing your invention to the Government (e.g., to the Ministry of Defence, the Department of Science, or a Government undertaking) does not count as a public disclosure.
  • Real-world example: You invent a new type of water-purification system. On March 1, you present your designs to a government committee to get a grant. They test a prototype. This communication and testing cannot be used as “prior art” to block your patent application, which you file on May 1. This rule encourages inventors to work with the government without fear.

Section 31: Anticipation by public display, etc.

This is a critical “grace period” for inventors who showcase their work at exhibitions or in academic papers. “Anticipated” means “not new.” This section says these specific acts do not make your invention “not new.”

• What it says: An invention claimed in a complete specification shall not be deemed to have been anticipated by reason only of—
  • In plain English: Your patent application will not be rejected just because of the following situations:
• (a) What it says: …the display of the invention… at an industrial or other exhibition to which the provisions of this section have been extended… or the use thereof… for the purpose of such an exhibition…
  • In plain English: You displayed your invention at an officially recognized exhibition (one that the Central Government has officially listed in the Official Gazette for this purpose). This also covers you using the invention as part of the demonstration at the expo.
  • Real-world example: You invent a new 3D printer. You book a stall at the “India International Innovation Fair,” which the government has recognized under this section. You display the printer and run it live for the public to see. This display cannot be used as “prior art” to reject your patent.
• (b) What it says: …the publication of any description of the invention in consequence of the display or use of the invention at any such exhibition…
  • In plain English: A media outlet (like a tech blog or newspaper) writes an article about your invention that they saw at that same recognized exhibition. This article also cannot be used as prior art against you.
  • Real-world example: A journalist from “Tech Today” magazine sees your 3D printer at the expo and publishes an article with pictures and a description. This publication is “in consequence” of the expo and is also protected.
• (c) What it says: …the use of the invention, after it has been displayed… and during the period of the exhibition, by any person without the consent of the true and first inventor…
  • In plain English: If a competitor sees your invention at the expo on Day 1, quickly makes a copy, and starts using it themselves in the expo hall on Day 2 without your permission, that unauthorized use also cannot be used as prior art against you.
• (d) What it says: …the description of the invention in a paper read by the true and first inventor before a learned society or published with his consent in the transactions of such a society…
  • In plain English: You presented your invention in an academic paper at a “learned society” (a recognized professional conference, like one by the IEEE, IMechE, or a medical association) OR it was published in that society’s official journal (its “transactions”).
  • Real-world example: A professor of biochemistry invents a new protein-folding algorithm. She presents a paper on it at the annual “Indian Society of Biochemists” conference. This presentation cannot be used as prior art.
• Crucial Proviso (at the end of Section 31): …if the application for the patent is made by the true and first inventor… not later than twelve months after the opening of the exhibition or the reading or publication of the paper, as the case may be.
  • In plain English: This is the most important part. This “grace period” is NOT indefinite. You only get this protection if you file your patent application within 12 months of the date the exhibition opened or the date your paper was read/published.
  • Real-world example: The expo opened on March 1, 2024. You must file your full patent application by February 28, 2025, for the grace period to apply. If you wait 13 months, your own display will be used to reject your patent.

Section 32: Anticipation by public working

This section provides a grace period for public testing of an invention.

• What it says: An invention… shall not be deemed to have been anticipated by reason only that at any time within one year before the priority date… the invention was publicly worked in India…
  • In plain English: Your patent application will not be rejected just because the invention was used in public, as long as that public use happened within the one-year period before your priority date.
• (a) & (b) What it says: …by the patentee or applicant… or… by any other person with the consent of the patentee or applicant…
  • In plain English: This applies if the public test was conducted by you (the inventor) or by someone you authorized to do the test.
• Crucial Proviso (at the end of Section 32): …if the working was effected for the purpose of reasonable trial only and if it was reasonably necessary, having regard to the nature of the invention, that the working for that purpose should be effected in public.
  • In plain English: You only get this grace period if you meet two strict conditions:
    1. Reasonable Trial Only: The public use was purely a test to see if it worked or to refine it. It was not for commercial use (i.e., you weren’t selling it).
    2. Reasonably Necessary: The invention, by its very nature, had to be tested in public. You couldn’t have tested it in a private, secret lab.
  • Real-world example: You invent a new type of road asphalt. You cannot test this in a lab; you must test it on an actual road to see how it holds up to traffic and weather. On May 1, 2024, you get permission to pave a 100-meter strip of a public street. This is a “public working” (people can see it), but it’s for “reasonable trial.” As long as you file your patent application by April 30, 2025 (within one year), this public test cannot be used to reject your application.

Section 33: Anticipation by use and publication after provisional specification

This section explains one of the main benefits of filing a provisional specification.

• (1) What it says: …where a complete specification is filed… in pursuance of an application which was accompanied by a provisional specification… the Controller shall not refuse to grant the patent… by reason only that any matter described in the provisional specification… was used in India or published in India or elsewhere at any time after the date of the filing of that specification.
  • In plain English: Once you file your provisional application, you get a 12-month “safe” period. Anything you do after filing the provisional (publish an article, sell the product, display it at a non-recognized expo) cannot be used as “prior art” to reject your patent. This is only true for the information that was actually in your provisional.
  • Real-world example:
    1. You file a provisional application for your new software on Jan 1, 2024.
    2. On Feb 1, 2024, you launch a public beta of the software and publish a blog post about it.
    3. On Dec 1, 2024, you file your complete application (within 12 months).
    4. The examiner cannot use your Feb 1 public launch or blog post as prior art, because they happened after your Jan 1 provisional filing date.
• (2) What it says: Where a complete specification is filed in pursuance of a convention application… [the same rule applies].
  • In plain English: This is the same rule, but for international (convention) applications. Once you file your first application in any convention country (e.g., in the USA), any publication or use after that US filing date cannot be used as prior art against your Indian application (as long as you file in India within 12 months).
  • Real-world example: You file in the USA on Jan 1, 2024. You present your invention at a US trade show on March 1, 2024. You file in India on Dec 1, 2024 (claiming the Jan 1 US priority). The examiner in India cannot use the March 1 trade show to reject your patent.

Section 34: No anticipation if circumstances are only as described in sections 29, 30, 31 and 32

This is a simple “house-keeping” section that ties the previous sections together.

• What it says: Notwithstanding anything contained in this Act, the Controller shall not refuse to grant a patent… by reason only of any circumstances which, by virtue of section 29 or section 30 or section 31 or section 32, do not constitute an anticipation…
  • In plain English: This section is a direct order to the Controller. It says: “To be crystal clear, if an applicant’s situation fits one of the exceptions we just listed (stolen publication, government disclosure, recognized exhibition, or public trial), you must not refuse their patent on that basis.” It confirms that these “grace periods” are binding.
