IP Litigation in India: Trademark, Patent, Copyright and Online Disputes

IP Litigation in India: Trademark, Patent, Copyright and Online Disputes

Intellectual property litigation concerns the enforcement, defence or challenge of rights arising from inventions, trademarks, creative works, designs and confidential information. The legal issues depend upon the particular intellectual property right and the conduct complained of.

Principal IP Rights

Indian intellectual property law includes statutory protection for trademarks, patents, copyright and registered designs. Confidential information and trade secrets may be protected through contractual and equitable principles. Different rights have different standards for acquisition, ownership, infringement and remedies.

Trademark Infringement and Passing Off

The Trade Marks Act, 1999 provides statutory protection to registered trademarks. Section 29 sets out circumstances in which a registered mark may be infringed, including specified cases involving identity or similarity and likelihood of confusion.

Passing off is a separate common-law remedy. It protects goodwill against misrepresentation that causes or is likely to cause damage. The evidence required for passing off differs from the statutory ingredients of trademark infringement.

Patent Disputes

Patent disputes require examination of the patent claims and the allegedly infringing product or process. Section 48 of the Patents Act identifies the exclusive rights of a patentee, subject to the Act.

Claim construction, validity, prior art and technical evidence may all become important. Commercial similarity between two products does not by itself establish patent infringement.

Copyright Disputes

Copyright protects qualifying expression. Section 51 of the Copyright Act identifies circumstances in which infringement occurs, subject to statutory exceptions and limitations.

Ownership, authorship, copying, assignment, licensing and fair dealing can become relevant. A claimant should identify the specific work and right allegedly infringed.

Design and Confidential-Information Disputes

Design litigation concerns registered designs under the Designs Act, 2000. Confidential-information disputes may concern contractual confidentiality, access restrictions, employee obligations and alleged misuse of commercially valuable information.

Online IP Litigation

Online disputes may involve websites, domain names, social-media accounts, marketplaces, applications and digital advertising. Electronic evidence can include website captures, domain information, screenshots, advertisements, platform records and transaction information.

Digital evidence should be preserved promptly because online content can be modified or removed.

Recent Delhi High Court Development

In an order dated 24 February 2026 in CS(COMM) 181/2026, the Delhi High Court considered allegations of trademark and copyright infringement involving websites, domain names, social-media material and digital advertisements. The order included restraints concerning specified infringing activity and directions concerning identified websites and domains.

The proceeding demonstrates that online IP enforcement may require relief concerning both the infringing conduct and the digital channels through which the material is made available, subject to the pleadings, evidence and applicable law.

Interim Injunctions

IP claimants may seek interim injunctions to prevent continuing conduct while the suit is pending. Courts ordinarily consider prima facie case, balance of convenience and irreparable injury along with the other facts of the matter.

An interim order is not ordinarily equivalent to a final adjudication. The final rights of the parties may require fuller evidence and trial.

Appellate Review

In Sanjay Gupta and Vinay Gupta v. Vineet Jain, FAO (COMM) 44/2026, decided on 11 February 2026, the Delhi High Court considered an appeal arising from a commercial IP dispute and discussed the limits on appellate interference with discretionary interim orders.

The Division Bench also examined trademark, passing-off and copyright submissions. The decision illustrates that appellate review of an interlocutory order focuses on whether the lower court exercised discretion according to settled principles rather than simply replacing that discretion with another possible view.

Evidence

Depending on the dispute, relevant evidence may include registration certificates, assignments, licences, invoices, advertisements, product packaging, creation records, correspondence, sales records and electronic material.

Patent disputes may require technical evidence. Copyright disputes may require source files and evidence of copying. Trademark disputes may require evidence of use, reputation and consumer-facing material.

Commercial Courts

Many commercial IP disputes fall within the framework of the Commercial Courts Act, 2015. Depending on the circumstances, parties may have to comply with requirements concerning disclosure, inspection, case management and pre-institution mediation.

Remedies

Depending on the right and cause of action, courts may grant injunctions, damages, account of profits, delivery-up or destruction of infringing material, declarations and other appropriate relief.

Licensing and Settlement

Commercial IP disputes can sometimes be addressed through licensing or settlement. Agreements should identify the IP, permitted uses, restrictions, consideration, confidentiality, future conduct and dispute-resolution terms.

Common Mistakes

• Failing to verify ownership.
• Using the wrong legal cause of action.
• Failing to preserve online evidence.
• Relying on general similarity rather than the applicable legal test.
• Ignoring statutory exceptions or defences.
• Failing to consider commercial-court procedure.
• Making unsupported claims concerning first use or originality.
• Ignoring assignment and licensing documents.
• Seeking relief broader than the relevant IP right permits.
• Failing to maintain evidence of commercial use.
