Patent Opposition in India

The patent opposition process in India provides a strong legal framework to challenge the validity of patent applications and granted patents. The patent opposition mechanism in India ensures that only genuine, novel, and non-obvious inventions receive patent protection while preventing the grant of invalid or weak patents. Under the Indian Patents Act, 1970 (as amended by the Patents Amendment Act, 2005), third parties can oppose a patent either:

• Before the grant of patent — Pre-Grant Opposition, or
• After the grant of patent — Post-Grant Opposition.

The patent opposition system in India is an administrative proceeding conducted before the Controller of Patents and serves as an important safeguard to maintain patent quality, prevent unjust monopoly, and protect public interest. The Indian patent law provides two types of patent opposition:

• Pre-Grant Opposition (Section 25(1))
• Post-Grant Opposition (Section 25(2))

These opposition proceedings help maintain the integrity of the patent system and ensure compliance with patentability requirements.

Pre-Grant Opposition in India (Section 25(1))

What is Pre-Grant Opposition?

Pre-grant opposition in India is a legal mechanism that allows any person to challenge a patent application after publication but before the patent is granted. It acts as an effective tool to prevent the grant of non-patentable, obvious, or invalid inventions. Pre-grant opposition is governed by Section 25(1) of the Indian Patents Act, 1970.

Who Can File Pre-Grant Opposition?

• Any person can file a pre-grant opposition in writing, represent by way of opposition to the Controller against the grant of patent on the certain grounds.

When to File Pre-Grant Opposition?

A pre-grant opposition representation may be filed:

• After publication of the patent application
• Before grant of the patent
• Only after a Request for Examination (RFE) has been filed.

The opposition is filed before the Controller of Patents along with supporting evidence.

Procedure for Pre-Grant Opposition: The pre-grant opposition procedure in India involves:

1. Filing representation of opposition (Form 7A) with supporting evidence.
2. Controller examines the representation after RFE.
3. If merit is found, notice is issued to the applicant.
4. Applicant responds within prescribed time (generally 3 months).
5. Controller reviews submissions of both parties.
6. Controller may reject opposition and grant patent, require amendment, or refuse patent application.

Pre-grant opposition acts as a strong filter to prevent the grant of weak patents.

Post-Grant Opposition in India (Section 25(2))

What is Post-Grant Opposition?

Post-grant opposition in India allows an interested person to challenge a patent after it has been granted. This mechanism ensures that invalid patents can be reviewed and revoked even after grant. Post-grant opposition is governed by Section 25(2) of the Indian Patents Act, 1970.

Who Can File Post-Grant Opposition?

Any person interested may give notice of opposition to the Controller in the prescribed manner on the below grounds. Time Limit for Post-Grant Opposition: A post-grant opposition must be filed within one year from the date of publication of grant of the patent.

Grounds for Post-Grant Opposition: The grounds for post-grant opposition are identical to pre-grant opposition:

• Wrongful obtaining of invention
• Prior publication or anticipation
• Prior claim
• Prior public knowledge or use
• Lack of inventive step
• Non-patentable subject matter
• Insufficient disclosure
• Non-compliance with Section 8
• Convention filing time violation
• Incorrect disclosure of biological source
• Anticipation based on traditional knowledge

Procedure for Post-Grant Opposition: The post-grant patent opposition process in India includes:

1. Filing notice of opposition with prescribed fee.
2. Controller notifies the patentee.
3. Opposition Board is constituted.
4. Board examines evidence from both parties.
5. Board submits recommendation to Controller.
6. Hearing is conducted.
7. Controller passes final order.
