Innovation alone does not guarantee a patent grant. Every year, many patent applications filed in India receive objections or are rejected because they fail to satisfy the legal and technical requirements of the Indian patent system. Fortunately, most rejections are preventable with proper preparation, accurate documentation, and a well-drafted patent application.

Understanding the common patent rejection reasons in India helps inventors, startups, researchers, and businesses improve their chances of securing strong intellectual property protection. If you have already received an objection, you can also learn more about Patent Rejection Reasons in India and How to Overcome Them for practical guidance on responding effectively.

Understanding Patent Rejection in India

A patent application filed with the Indian Patent Office undergoes a detailed examination under the Patents Act, 1970. During this examination, the patent examiner evaluates whether the invention satisfies all legal requirements, including:

Novelty

Inventive Step

Industrial Applicability

Patentable Subject Matter

Complete Disclosure

Proper Patent Claims

If any of these requirements are not fulfilled, the examiner may issue objections through the First Examination Report (FER). If the objections are not satisfactorily addressed, the application may eventually be refused.

1. Lack of Novelty

Novelty is one of the most important patentability requirements. An invention must be new and should not have been disclosed anywhere in the world before the filing date.

A patent may be rejected if:

Similar patents already exist

The invention has been published

The invention has been publicly demonstrated

Existing products already disclose the same concept

How to Avoid It

Conduct a comprehensive patent search before filing.

Review both Indian and international patent databases.

Identify prior art early.

Clearly explain how your invention differs from existing technology.

2. Lack of Inventive Step (Obviousness)

Even if an invention is new, it must also involve an inventive step. If the invention appears obvious to someone skilled in the relevant technical field, the patent application may be rejected.

For example, simply combining two existing technologies without producing an unexpected technical advantage may not qualify for patent protection.

How to Avoid It

Highlight the technical advancement achieved.

Explain the problem solved by the invention.

Demonstrate unexpected results or improved efficiency.

Include comparative technical data wherever applicable.

3. Subject Matter Not Eligible for Patent

Not every idea qualifies for patent protection in India.

Certain inventions are excluded under Sections 3 and 4 of the Patents Act, including:

Mathematical methods

Business methods

Abstract ideas

Algorithms

Discoveries of natural substances

Certain medical treatment methods

Traditional knowledge

Applications covering excluded subject matter are likely to be rejected.

How to Avoid It

Verify patent eligibility before filing.

Focus on technical innovation rather than abstract concepts.

Seek professional evaluation of patentability.

4. Poorly Drafted Patent Specification

Many strong inventions fail because the application is not drafted properly.

Common drafting mistakes include:

Vague descriptions

Missing technical information

Poor organization

Inconsistent terminology

Insufficient explanation of working principles

A poorly drafted specification makes it difficult for the examiner to understand the invention.

How to Avoid It

Prepare a complete and detailed specification.

Explain every technical feature clearly.

Include embodiments, examples, and drawings where necessary.

Ensure consistency throughout the application.

5. Weak or Ambiguous Patent Claims

Patent claims define the legal protection sought by the inventor. Weak claims are one of the most common reasons for patent objections.

Claims may be rejected if they are:

Too broad

Too narrow

Unsupported by the specification

Ambiguous

Technically unclear

How to Avoid It

Draft claims carefully.

Ensure every claim is supported by the specification.

Maintain clarity and precision.

Include independent and dependent claims appropriately.

6. Insufficient Disclosure

Indian patent law requires that the invention be disclosed in sufficient detail so that a person skilled in the field can reproduce it.

If important technical information is missing, the examiner may object that the invention is not fully enabled.

How to Avoid It

Include:

Complete working process

Technical architecture

Flowcharts

Drawings

Examples

Experimental results where applicable

7. Prior Art Conflicts

Patent examiners conduct extensive prior art searches during examination.

If prior art shows that similar technology already exists, objections are likely.

Prior art may include:

Earlier patents

Published patent applications

Scientific journals

Research papers

Technical articles

Public demonstrations

How to Avoid It

Perform detailed prior art searches before filing.

Identify distinguishing technical features.

Clearly explain improvements over existing technologies.

8. Failure to Meet Formal Requirements

Some applications face rejection because of procedural errors rather than technical issues.

Examples include:

Incorrect forms

Missing declarations

Improper drawings

Incorrect inventor information

Missing signatures

Late submissions

How to Avoid It

Review all filing documents carefully.

Follow Indian Patent Office requirements.

Meet all statutory deadlines.

9. Inadequate Response to First Examination Report (FER)

Receiving a First Examination Report does not automatically mean the application has been rejected.

However, submitting an incomplete or poorly reasoned response may result in refusal.

How to Avoid It

Address every objection individually.

Provide technical explanations.

Amend claims where necessary.

Submit responses within prescribed timelines.

Support arguments with legal and technical reasoning.

10. Premature Public Disclosure

Many inventors unintentionally disclose their inventions before filing a patent application.

Examples include:

Conferences

Product launches

Social media posts

Research publications

Investor presentations

Once publicly disclosed, the invention may lose novelty.

How to Avoid It

File the patent application before public disclosure.

Use Non-Disclosure Agreements (NDAs) when discussing the invention.

Maintain confidentiality until filing.

Best Practices to Reduce Patent Rejection Risks

Improving patent approval chances begins long before filing.

Some recommended practices include:

Conduct a detailed patentability search.

Prepare a comprehensive patent specification.

Draft strong patent claims.

Clearly explain the inventive concept.

Include complete technical disclosure.

Review compliance with Indian patent laws.

Respond promptly and accurately to examination reports.

Keep detailed records of invention development.

Why Professional Patent Drafting Matters

Patent drafting is both a legal and technical exercise. A professionally prepared application helps:

Clearly define the invention.

Strengthen patent claims.

Improve examination outcomes.

Reduce objections.

Increase commercial value.

Build stronger intellectual property protection.

Many avoidable rejections result from drafting deficiencies rather than weak inventions. Investing time in preparing a high-quality application can significantly improve the likelihood of a successful patent grant.

Conclusion

Patent rejection is not always a reflection of the quality of an invention. In many cases, applications are refused because of avoidable issues such as inadequate disclosure, weak claims, lack of novelty, procedural mistakes, or non-compliance with legal requirements. By understanding these common patent rejection reasons in India, inventors can prepare stronger applications and reduce unnecessary delays.

A well-researched, properly drafted, and legally compliant patent application significantly improves the chances of successful registration while providing stronger protection for valuable innovations.

Protect your innovation. Secure your future with Patent Registration India.

Innovation is evolving faster than ever, and patent law is struggling to keep pace. One of the most debated concepts in patent law today is “obviousness”—the legal standard used to determine whether an invention is sufficiently innovative to deserve patent protection. Across India, the United States, Europe, and other jurisdictions, courts and patent offices are redefining how they evaluate inventive step and non-obviousness, especially in technology-driven sectors like AI, software, biotechnology, and electronics.

Businesses, startups, inventors, and researchers filing patents today must understand how these changing standards can impact patent validity, prosecution strategy, and global protection. If you are planning to secure your invention, understanding the evolving landscape of Patent Obviousness Standards is now more important than ever.

What Is Patent Obviousness?

Patent obviousness refers to whether an invention would have been obvious to a person skilled in the relevant field at the time of filing. If an invention is considered obvious based on existing knowledge or prior art, the patent application may be rejected.

Different countries use different terminology:

India uses the concept of Inventive Step

The United States uses Non-Obviousness

Europe refers to Inventive Step under the Problem-Solution Approach

Although the wording differs, the core idea remains the same: patents should only be granted for genuine technical advancement.

Patent Obviousness Under Indian Patent Law

In India, Section 2(1)(ja) of the Patents Act defines inventive step as:

“A feature of an invention that involves technical advance or economic significance or both and makes the invention not obvious to a person skilled in the art.”

Traditionally, Indian patent examiners adopted a relatively strict approach toward inventive step. However, recent judicial decisions and updated examination guidelines indicate that India is gradually adopting a more nuanced and globally harmonized interpretation.

Key Trends Emerging in India

1. Greater Recognition of Technical Effect

Indian authorities are increasingly focusing on whether an invention produces a measurable technical effect rather than merely examining whether components already existed in prior art. This shift is especially relevant for software and AI-related inventions.

Examples of technical effects include:

Faster processing speed

Reduced memory consumption

Improved security

Better network efficiency

Enhanced machine performance

This approach benefits startups and tech companies filing software-based patent applications.

2. CRI Guidelines 2025 Are Reshaping Examination

The Indian Patent Office’s revised CRI (Computer Related Inventions) Guidelines 2025 have significantly influenced patent examination standards. The updated framework incorporates modern technologies such as AI, blockchain, machine learning, and quantum computing.

The guidelines emphasize:

Technical contribution analysis

Structured examination methods

Judicial precedents

Clarification of “computer program per se”

As a result, many inventions previously rejected as obvious or non-patentable may now receive more balanced evaluation.

3. Indian Courts Are Becoming More Innovation-Friendly

Indian courts have increasingly recognized that modern technological inventions often combine known elements in innovative ways. A combination is not automatically obvious merely because individual components were known previously.

This shift encourages deeper examination into:

Unexpected technical outcomes

Functional integration

Real-world industrial application

The result is a more practical and commercially aware interpretation of inventive step.

Global Changes in Patent Obviousness Standards

Patent systems worldwide are also undergoing transformation as emerging technologies challenge traditional legal principles.

United States: Flexible Obviousness Standards

The United States has historically applied the famous KSR v. Teleflex decision, which introduced a flexible and common-sense approach to obviousness analysis.

Recently, the USPTO issued updated guidance emphasizing:

Flexible interpretation of prior art combinations

Consideration of common knowledge

Stronger factual reasoning for obviousness rejections

Greater emphasis on objective evidence of non-obviousness

This means patent applicants must now provide stronger technical arguments and evidence showing why their invention was not predictable.

AI Is Changing the PHOSITA Standard

One major global development is the impact of AI on the “Person Having Ordinary Skill In The Art” (PHOSITA).

As AI tools become more capable, patent offices may assume that certain innovations are easier to achieve, making inventions appear more obvious. Legal experts are actively debating whether AI-assisted innovation raises the standard for patentability.

This trend may significantly affect:

Software patents

Machine learning inventions

Data optimization systems

Automated engineering solutions

Europe: Problem-Solution Approach Continues to Evolve

The European Patent Office (EPO) continues to apply the “problem-solution approach,” which involves:

Identifying the closest prior art

Determining the technical problem

Assessing whether the solution would have been obvious

European examiners increasingly focus on:

Technical contribution

Objective technical problems

Evidence-based analysis

This creates a relatively predictable but technically demanding examination framework.

Why These Changes Matter for Patent Applicants

Changing obviousness standards directly impact:

Patent approval chances

Litigation outcomes

Patent portfolio value

Investor confidence

Licensing opportunities

A poorly drafted patent application may now face stronger inventive step objections globally.

Businesses filing patents internationally must adapt their drafting strategy to meet evolving expectations across multiple jurisdictions.

Best Practices to Overcome Obviousness Rejections

1. Highlight Technical Advantages Clearly

Patent applications should explain:

Technical improvements

Unexpected results

Performance benefits

Efficiency gains

Clear technical storytelling improves patentability.

2. Use Comparative Data

Including experimental results or comparative performance data can strengthen inventive step arguments.

3. Draft Strong Problem-Solution Narratives

Explain:

What problem existed previously

Why prior art failed

How the invention solves the issue differently

This approach aligns well with global patent examination trends.

4. Avoid Broad Generic Claims

Overly broad claims are more vulnerable to obviousness objections. Carefully structured claim drafting improves enforceability.

5. File Strategically Across Jurisdictions

Patent standards differ across countries. A coordinated international filing strategy helps maintain stronger protection globally.

India’s Growing Role in Global Innovation

India is rapidly emerging as a major innovation hub with record patent filings and increasing domestic participation. Recent reforms, startup incentives, and modernization efforts are making the Indian patent ecosystem more competitive globally.

As innovation increases, scrutiny of inventive step and obviousness will continue to evolve.

Future of Patent Obviousness Standards

The future of patent law will likely involve:

AI-assisted patent examination

Data-driven prior art analysis

Stronger technical disclosure requirements

Increased scrutiny for incremental innovation

Greater harmonization between patent offices

At the same time, courts and patent offices must balance innovation protection with preventing monopolies on routine technological developments.

Final Thoughts

Patent obviousness standards are undergoing significant transformation in India and globally. Emerging technologies, AI-driven innovation, and judicial reforms are reshaping how inventive step is evaluated.

For inventors, startups, and enterprises, understanding these changes is essential for building strong and enforceable patent portfolios. A carefully drafted patent application that clearly demonstrates technical advancement and non-obviousness can substantially improve the likelihood of patent grant and long-term protection.
