Novelty Requirement in the Indian Patents Act, 1970
Novelty means the invention must not have been anticipated by prior publication or use anywhere in the world before the patent application filing date. This is defined under Section 2(1)(l) of the Act, emphasizing global standards.
Novelty is checked against prior art, which includes all existing public knowledge like books, journals, and public uses. The Indian system follows absolute novelty, meaning even foreign disclosures can affect patentability.
A 12-month grace period exists for disclosures in specific contexts, such as government exhibitions or learned society presentations, allowing inventors some flexibility. However, certain novel inventions, like new forms of known substances without enhanced efficacy, are not patentable under Section 3.
Legal Framework and Definition
The Act, under Section 2(j), defines an invention as "a new product or process involving an inventive step and capable of industrial application." Specifically, Section 2(1)(l) elaborates on novelty, stating that a "new invention" is one not anticipated by:
Publication in any document, or
Use in the country or elsewhere in the world before the date of filing of the patent application with a complete specification.
This definition underscores the global scope of novelty, aligning with international patent standards and emphasizing that any prior disclosure, whether domestic or international, can impact patentability.
Criteria for Patentability
For an invention to be patentable, it must satisfy multiple criteria, as outlined in official documents from the Indian Patent Office. These include:
Novelty: The invention must be new, as defined above.
Inventive Step: It must not be obvious to a person skilled in the relevant field.
Industrial Application: It must be capable of being used in industry.
Exclusions: It must not fall under Sections 3 and 4, which list non-patentable inventions.
The novelty requirement is thus a foundational element, ensuring that only truly innovative inventions receive patent protection.
Anticipation and Prior Art
Novelty is assessed by examining anticipation, detailed in Chapters VI (Sections 29-34) of the Act. Anticipation occurs if the invention has been:
Published in any document (Section 29), such as books, journals, or online publications.
Communicated to the government (Section 30), which may include disclosures for regulatory purposes.
Publicly displayed or exhibited (Section 31), such as at trade shows or government-organized exhibitions.
Publicly worked or used (Section 32), meaning the invention was used in a way accessible to the public.
Prior art includes all existing knowledge in the public domain. This encompasses:
Publications worldwide.
Existing products and processes.
Traditional knowledge in India, which is increasingly considered in patent examinations.
The Indian patent system follows absolute novelty, meaning that even prior use outside India forms part of the prior art, making the threshold stringent compared to jurisdictions with relative novelty standards.
Grace Period Provisions
To balance innovation with disclosure, the Act provides a 12-month grace period for filing a patent application from the date of certain disclosures, as per Sections 29-34. This applies to:
Publication in a journal.
Public display in a government-organized exhibition.
Disclosure before a learned society.
This grace period allows inventors to present their work publicly without immediately losing patent rights, provided they file within the stipulated period. The amendment introduced Form 31 for availing this grace period, requiring disclosure of the earliest date of use, publication, or disclosure.
Non-Patentable Inventions and Novelty
Even if an invention meets the novelty criterion, it may still be non-patentable under Sections 3 and 4. Examples include:
Mere Discovery: Scientific principles, abstract theories, or natural substances (Section 3(c)), as these are not considered inventions but discoveries of existing phenomena.
New Forms of Known Substances: Unless they result in enhanced efficacy, such as new salts or esters of known drugs without significant improvement (Section 3(d).
Mere Admixture: If it only results in the aggregation of properties of its components (Section 3(e)), such as mixing known substances without a synergistic effect.
Arrangement of Known Devices: Mere arrangement, re-arrangement, or duplication of known devices (Section 3(f)), which does not constitute a new invention.
These exclusions ensure that patents are granted only for genuine innovations, not for trivial modifications.

Historical Context and Amendments
The Patents Act, 1970, replaced the Indian Patents and Designs Act, 1911, and has been amended multiple times to align with global standards, particularly the TRIPS Agreement under the WTO. Key amendments include:
1999 Amendment: Introduced provisions for mailbox applications and exclusive marketing rights, preparing for TRIPS compliance.
2002 Amendment: Further aligned with TRIPS, focusing on patent term extensions.
2005 Amendment: A significant shift, introducing product patents for pharmaceuticals and chemicals, previously limited to process patents. This amendment extended the patent term to 20 years and expanded patentable subject matter but did not alter the novelty definition.
2006 and Later Amendments: Focused on procedural changes, such as the 2024 amendment introducing Form 31 for grace period applications, but no changes to the substantive novelty requirement were identified.
The latest version of the Act, as per the Indian Patent Office, incorporates amendments up to June 23, 2017, with no recent changes affecting novelty as of 2025.
Summary
The novelty requirement under the Indian Patents Act, 1970 ensures that only genuinely new inventions receive patent protection, with a global scope and strict standards. The 12-month grace period and exclusions for certain novel inventions balance innovation with public interest. Amendments have primarily expanded patentable subjects, with no recent changes to the novelty criteria as of 2025, maintaining consistency in this foundational aspect of patent law.
