Patent Infringement Remedies and Claiming Damages in India

Updated: July 15, 2026Published: July 15, 2026

Quick Answer

When a patent is infringed in India, the patentee can file a civil suit under the Patents Act, 1970, to secure immediate interim injunctions stopping the violator, followed by a permanent injunction and either monetary damages or an account of the infringer's profits.

Key Takeaways

  • Only a formally granted patent can be enforced in court; pending applications cannot be sued upon.
  • Section 104 of the Patents Act dictates that infringement suits must be filed in a District Court or High Court.
  • Plaintiffs can choose to claim either actual financial damages or the profits made by the infringer.
  • Defendants frequently counter-sue for the revocation (invalidity) of the patent to dismiss the infringement claim.

Introduction

Developing a novel invention requires massive investments in research and development. When competitors reverse-engineer your product or unlawfully manufacture your patented technology, it directly cannibalizes your market share. In India, the patent system offers aggressive civil remedies to halt unauthorized manufacturing and recover financial losses. Understanding the enforcement mechanism under the Patents Act is crucial for inventors and corporations looking to safeguard their R&D investments and monetize their intellectual property.

Patent enforcement in India is strictly governed by the Patents Act, 1970 (as amended).

  • Registered Rights Only: Unlike copyright or trademarks (which offer some common-law protection without registration), patent rights are entirely statutory. You cannot file an infringement suit for an invention unless the Office of the Controller General of Patents, Designs and Trademarks (CGPDTM) has formally granted the patent. However, once granted, you can claim damages retrospectively from the date your application was officially published.
  • Jurisdiction (Section 104): An infringement suit must be instituted in a District Court or a High Court with original jurisdiction (such as the Delhi High Court IP Division). If the defendant files a counterclaim seeking to revoke (invalidate) your patent, the case is automatically transferred to the High Court.
  • The Act of Infringement: Infringement occurs if a third party makes, uses, offers for sale, sells, or imports the patented product or process in India without the patentee's consent.

Under Section 108 of the Patents Act, a successful plaintiff is entitled to several powerful civil remedies:

  1. Interim (Temporary) Injunction: The most sought-after remedy. The court orders the defendant to immediately halt manufacturing or selling the product during the pendency of the trial. The court will grant this if the plaintiff establishes a prima facie case, irreparable loss, and a balance of convenience in their favor.
  2. Permanent Injunction: A final court order perpetually banning the defendant from infringing the patent for its remaining 20-year lifespan.
  3. Damages OR Account of Profits: The patentee must choose one financial remedy. "Damages" compensates the patentee for actual sales lost due to the infringement. "Account of Profits" forces the infringer to hand over the actual illegal profits they generated from selling the stolen technology.
  4. Seizure and Destruction: The court can order the confiscation and destruction of the infringing goods and the specialized machinery used to create them.

Practical Tips

  • Preserve Infringement Evidence: To protect your IP rights during litigation, you must preserve hard evidence. Purchase the infringing product, keep the receipt, and commission an independent technical expert to draft a "Claim Chart" or reverse-engineering report mapping the competitor's product directly to your specific patent claims.
  • Maintain Commercial Usage Logs: Courts are more likely to grant interim injunctions if you can prove you are actively manufacturing and commercializing the patent. Preserve sales data, licensing agreements, and R&D expenditure records.
  • Issue a Cease and Desist Letter: Before rushing to court, send a formal legal notice warning the infringer. Preserve this correspondence, as ignoring a legal notice demonstrates the infringer's bad faith to the judge.

When Should You Consult a Lawyer?

Patent litigation is arguably the most complex form of civil law. You must retain a specialized patent litigator when:

  • Facing a Counterclaim for Revocation: Defendants almost always fight back by claiming your patent is invalid (e.g., lacks novelty) under Section 64. Defending your patent's validity requires deep technical and legal expertise.
  • Drafting the Plaint: Articulating exactly how the defendant's technology maps onto your granted patent claims requires precise legal drafting to secure an ex-parte injunction.
  • Dealing with Groundless Threats: If a larger competitor falsely accuses your startup of patent infringement to scare away your investors, a lawyer can file a suit under Section 106 to stop their groundless threats.

Conclusion

A granted patent is only as valuable as the owner's willingness to enforce it. The Patents Act, 1970, provides a highly structured framework to halt IP theft through injunctions and recover economic losses via damages or an account of profits. By actively monitoring the market, preserving rigorous technical evidence of infringement, and swiftly engaging the High Court IP divisions, patentees can successfully defend their technological monopolies and deter future copycats.

Frequently Asked Questions

Q: Can I sue for infringement while my patent application is still pending?

A: No. You cannot initiate a patent infringement lawsuit until the patent is officially granted by the patent office. However, once granted, you can claim financial damages retrospectively starting from the date your application was published.

Q: What is the difference between damages and an account of profits?

A: Damages aim to compensate the patent holder for the money they lost because the infringer stole their customers. An account of profits ignores the patent holder's losses and instead forces the infringer to surrender the illicit profits they made from the stolen invention. You can only choose one.

Q: Can the police arrest someone for infringing my patent?

A: No. Unlike copyright and trademark laws, which contain specific criminal provisions for piracy and counterfeiting, patent infringement in India is purely a civil wrong. You must file a civil suit; you cannot file a police FIR for patent infringement.
