With the rapid growth of innovation in India, patent disputes are increasingly common, making it essential for businesses and innovators to understand how the litigation process works.
This guide provides a clear overview of patent litigation, what qualifies as patent infringement, the jurisdiction for filing cases, and the key legal terms surrounding such disputes.

Patent Litigation in India: Important Details
Patent litigation refers to legal proceedings initiated to address disputes concerning patents—most commonly involving allegations of infringement or challenges to the validity of a granted patent. In India, such matters are governed by the Indian Patents Act, 1970, which outlines the rights of patent holders, the remedies available in case of infringement, and the procedures for contesting a patent.
Patent litigation plays a critical role in protecting the intellectual property rights of inventors, startups, research institutions, and large enterprises. It ensures that innovations—often the result of years of research and investment—are not unfairly exploited by others without consent.
When Does Patent Litigation Arise?
Patent litigation may be triggered in a variety of situations, such as:
-
Unauthorized Use, Sale, or Import of a Patented Invention
If a person or business uses, manufactures, sells, or imports a patented product or process without the consent of the patent holder, it constitutes patent infringement—often the most common reason for litigation.
-
Challenge to Patent Validity
A third party may file a counterclaim or petition to revoke the patent, arguing that it was granted without fulfilling legal requirements such as novelty, inventiveness, or industrial applicability.
-
Disputes Over Licensing or Royalty Agreements
Even when permission has been granted via a license, conflicts can arise over the interpretation of licensing terms, royalty payments, or scope of use.
-
Ownership and Inventorship Conflicts
Sometimes, disputes occur over who rightfully owns a patent or should be credited as the inventor(s), especially in collaborative projects or employee-employer arrangements.
In such scenarios, litigation becomes necessary to assert or defend legal rights, seek compensation for damages, and clarify ownership. These legal proceedings may involve both civil remedies—such as injunctions and monetary damages—as well as administrative proceedings like patent revocation. Understanding when and how to initiate legal action is key to safeguarding your innovation in India’s competitive market.
What Is Not Considered Patent Infringement in India?
Indian patent law acknowledges several exceptions to what may otherwise be considered patent infringement. These exceptions allow limited use of a patented invention under specific conditions without the patent owner’s consent.
1. Use for Experiments or Research
Under Section 47 and Section 107A of the Indian Patents Act:
- Using a patented product or process for experiments or academic research does not count as infringement.
- Preparing information for submission to regulatory authorities (such as for drug approvals) is permitted—known as the Bolar Exception.
Example:
If a pharmaceutical company uses a patented drug compound to conduct bioequivalence studies for regulatory filing, it is not considered infringement under Indian law.
Other exceptions include:
- Private and non-commercial use of the invention.
- Use for government purposes, including public services or national interest.
- Use of a patented invention on foreign vessels or aircraft temporarily or accidentally present in Indian territory.
Understanding these exceptions is essential for those conducting R&D or collaborating with academic institutions.
Where to File Patent Litigation in India?
The jurisdiction of patent litigation in India is primarily determined by the location of the alleged infringement or the residence of the defendant.
Here’s how jurisdiction works:
1. District Courts:
Most patent litigation matters begin at the district court level, especially where the cause of action arises.
2. High Courts with Original Jurisdiction:
In metro cities like Delhi, Mumbai, Chennai, and Kolkata, High Courts have original jurisdiction to hear such matters directly.
3. Commercial Courts:
Post the Commercial Courts Act, 2015, patent disputes with a specified commercial value are transferred to designated commercial courts.
If the defendant resides or conducts business in a particular location, the litigation must be filed in the court that holds jurisdiction over that area.
Other Names for Patent Litigation
The term “patent litigation” may also be referred to in different contexts using alternative terminology. These variations are common in legal discussions or documentation:
- Patent Dispute Resolution
- IP Dispute Litigation
- Patent Infringement Proceedings
- Patent Enforcement Actions
- Patent Lawsuit
- Intellectual Property (IP) Litigation
These terms may be used interchangeably in India depending on the stage or scope of the legal process.
