Understanding Patent Opposition 

Patent opposition allows third parties to contest the validity of a patent during its examination or after it has been granted. This ensures that only inventions meeting stringent legal and technical standards receive protection. 

Pre-Grant Opposition: 

  • Filed during the patent application’s examination phase, before the grant. 
  • Grounds include lack of novelty, inventive step, insufficient disclosure, or non-patentable subject matter. 
  • Prevents undeserving patents from being granted, safeguarding market fairness. 

Post-Grant Opposition: 

  • Filed after the patent is granted but within 12 months under Indian law. 
  • Provides a window for third parties to challenge the validity of a granted patent on various legal and technical grounds. 

Common Reasons to Challenge Patents

Lack of Novelty or Inventive Step

Patent claims overlap with prior art, rendering the invention non-novel or obvious to someone skilled in the field.

Non-Patentable Subject Matter

The invention falls outside the scope of patentable subject matter as defined by Indian Patent Law.

Insufficient Disclosure or Non-Enablement

The patent does not provide enough information for a skilled person to reproduce or practice the invention effectively.

Fraud or Misrepresentation

False claims, omissions, or fraudulent actions during the patent application process can lead to challenges.

Violation of Public Order or Morality

Patents that conflict with public policy, ethical considerations, or societal norms.

Failure to Disclose Best Method

Clear and concise responses help establish the invention’s novelty, inventive step, and industrial applicability effectively.

Step-by-Step Approach to Patent Challenges

Case Assessment

Review the patent and identify potential grounds for opposition or revocation. Analyze prior art and technical documentation to determine the strength of the challenge.

Evidence Collection

Gather supporting materials such as prior art references, expert opinions, and technical data. Evaluate inconsistencies or deficiencies in the patent’s claims and specifications.

Drafting and Filing

Prepare detailed and persuasive statements of objections or petitions. Ensure compliance with procedural requirements and file documents with the appropriate authorities.

Representation

Represent clients during hearings before the patent office, IPAB, or courts. Advocate effectively to defend client interests with strong legal and technical arguments.

Track the progress of proceedings and address additional challenges or counterclaims as needed. Provide ongoing support to secure a favorable outcome for the client.

FAQs

What is the difference between opposition and revocation?

Opposition challenges a patent’s validity during or shortly after the grant process, while revocation cancels a granted patent due to non-compliance with legal criteria. 

Any interested party, including competitors, industry stakeholders, or public interest groups, can file an opposition. 

  • Pre-Grant Opposition: Filed during the examination phase before the patent is granted. 
  • Post-Grant Opposition: Filed within 12 months of the patent grant. 
  • Revocation: Can be initiated anytime during the patent’s validity period. 

Costs vary based on the complexity of objections and the extent of amendments required. Contact us for a tailored quote that suits your needs.
