TMArtificial Intelligence is moving from being a private productivity tool to becoming part of the institutional machinery of patent examination in India. On 7 August 2026, the Office of the Controller General of Patents, Designs & Trade Marks published the Guidelines for the Use of Artificial Intelligence in Patent Examination Procedures. The Guidelines seek to capture the efficiency benefits of AI while preserving confidentiality, independent application of mind, accuracy and accountability in patent examination.
The development is significant not because the Guidelines permit AI to decide patent applications, but because they establish a human-in-the-loop model: AI may assist the Examiner or Controller, but it cannot replace the statutory and quasi-judicial responsibility of the officer.
From AI Experimentation to Structured Patent Examination
Patent examination is particularly suited to selective AI assistance. It involves large volumes of technical documents, classification, prior-art searching, translation, comparison of disclosures and legal research. The Guidelines recognise that AI may assist with tasks such as screening, classification, search, translation support, drafting support, technical comparison and knowledge retrieval.
The document distinguishes between public AI tools and private AI tools operating in closed or restricted environments. This distinction is important in patent practice because unpublished patent applications contain commercially sensitive technical information.
The policy approach is consistent with India’s broader Responsible AI framework. NITI Aayog’s Responsible AI documents emphasise principles including safety and reliability, privacy and security, transparency and accountability.
The Indian Patent Office Guidelines therefore adopt a pragmatic position: AI can improve efficiency, but the examiner must remain responsible for the result.
Human Judgment Remains at the Centre
The most important principle in the Guidelines is human oversight.
The Examiner or Controller remains fully responsible for every official act involving AI. Any AI-assisted output that influences examination must be manually reviewed and validated before adoption. The officer must personally satisfy themselves that the output is correct, relevant and appropriate.
This safeguard becomes particularly important when AI is used for substantive patent analysis.
For example, AI may help identify potential IPC or CPC classifications, generate search terms or identify potentially relevant prior-art documents. But the Guidelines require the officer to verify the classification against authenticated sources and the claims and specification. Search results must similarly be assessed against the claims and complete specification.
The distinction is crucial. AI may assist the search; it does not determine novelty or inventive step.
The Risks Are More Than Hallucinations
Much discussion around legal AI focuses on hallucinations. The Guidelines take a more nuanced view.
They identify risks including fabricated citations, omission of critical claim features, false pattern matching, loss of technical context, classification drift, excessive breadth or narrowness, black-box opacity, confidentiality risks, incomplete or outdated information and bias in training data.
The problem can be especially serious in patent examination. A document may appear technically similar but fail to disclose a particular claim limitation. An AI system may also combine separate teachings in a manner that does not accurately reflect the prior art.
The Guidelines are particularly cautious about novelty and inventive-step analysis. AI-generated reasoning may overlook distinguishing features, misread prior art, improperly combine disclosures or introduce hindsight. Accordingly, such analysis requires substantial human scrutiny.
The same caution applies to legal research. AI may fabricate quotations or misstate the ratio of a judgment. The Guidelines therefore require verification against the primary source before relying on AI-generated legal authorities.
Confidentiality and Prohibited Uses
For patent applicants and their representatives, perhaps the most consequential provision concerns confidential information.
The Guidelines prohibit entering unpublished patent application contents, confidential Patent Office records or internal deliberative material into public AI tools. They also prohibit using AI as a substitute for the Examiner’s or Controller’s own application of mind on substantive matters such as novelty, inventive step, industrial applicability, sufficiency, clarity or unity of invention.
They further prohibit issuing FERs, office actions, hearing notices, decisions or other official communications solely on AI-generated output, as well as relying upon AI-generated citations without independent verification.
For applicants, this provides an important assurance: AI-assisted examination is not intended to become automated adjudication.
Governance, Accountability and the Road Ahead
The Guidelines contemplate a broader institutional governance structure. A proposed AI Governance Committee may oversee tool approval, permitted and prohibited uses, safeguards, pilot projects, quality review, complaints and periodic revision of the Guidelines. The proposed committee includes representatives from the Examination Division, IT Office and Quality Management System Division.
The Guidelines also contemplate training in AI limitations, confidentiality, prompt discipline, verification and detection of hallucinated or fabricated material, together with possible independent audits, impact assessments, feedback mechanisms and incident reporting.
For patent attorneys, agents and international associates, the message is equally important. AI-assisted prosecution will increasingly require professionals to understand not only patent law but also AI reliability, data governance and verification methodology.
Conclusion
The 2026 AI Guidelines represent an important step towards the responsible integration of AI into Indian patent examination. Their central philosophy is neither unrestricted automation nor resistance to technological change. It is controlled augmentation.
The real test will now be implementation. AI can accelerate classification, searching, translation and information retrieval, but patent examination ultimately involves technical judgment, legal reasoning and decisions affecting valuable proprietary rights.
The emerging principle is therefore simple:
AI may assist the Examiner. It cannot become the Examiner.
For the Indian patent system, that distinction may prove to be the most important safeguard as AI becomes increasingly embedded in examination practice.
