DEFINITION OF NOVELTY IN PATENT LAW (Detailed LL.B. Exam Answer)
1. Basic Meaning
Novelty means “newness.”
In patent law, novelty means that the invention must be new in the eyes of law and must not have been disclosed to the public anywhere in the world before the date of filing of the patent application.
2. Statutory Definition (India)
Under Section 2(1)(l) of the :
“New invention” means any invention or technology which has not been anticipated by publication in any document or used in the country or elsewhere in the world before the date of filing of patent application.
This shows that India follows the principle of absolute novelty.
3. Meaning of Absolute Novelty
Absolute novelty means:
- The invention must not be published anywhere in the world.
- It must not be publicly used anywhere in the world.
- It must not be known to the public anywhere in the world.
Even a single prior publication in a foreign country can destroy novelty in India.
4. What Destroys Novelty?
Novelty is destroyed by anticipation. Anticipation may occur by:
- Prior Publication – If already described in any book, journal, patent, website.
- Prior Public Use – If publicly used before filing date.
- Prior Knowledge – If known to the public.
- Prior Claiming – If claimed in earlier patent application.
5. Judicial Definition of Novelty (Case Law)
1.
The Supreme Court held:
- A patent must involve real invention.
- Mere workshop improvement or minor change is not new.
- If a skilled person can easily make it, it lacks novelty.
Principle: Novelty must be substantial and meaningful.
2.
The Court held:
- If the invention is already known to the public before filing date, it is not novel.
- Burden of proof lies on the patentee.
Principle: Public knowledge destroys novelty.
3.
Court explained:
- Prior publication must clearly and unmistakably disclose the invention.
- If a skilled person can perform the invention from earlier document, novelty is destroyed.
6. Essential Elements of Novelty
For an invention to be novel:
- It must not form part of prior art.
- It must not have been disclosed publicly.
- It must not have been used publicly.
- It must not have been claimed earlier.
7. Difference Between Novelty and Inventive Step
| Novelty | Inventive Step |
|---|---|
| Must be new | Must not be obvious |
| Compared with prior art | Compared with skilled person |
| First requirement | Second requirement |
Even if invention is new, it must also be non-obvious to be patentable.
8. Simple Example
If a medicine formula is published in a US journal before filing in India → It is not novel in India.
If a machine was publicly demonstrated before filing → Novelty is destroyed.
9. Conclusion (Exam-Oriented Definition)
Novelty in patent law means that an invention must be new, not previously published, not publicly used, and not known anywhere in the world before the filing date.
It is the first and most essential condition for patentability under the Patents Act, 1970.
