01 — The Essentials
What Is a Patent Troll?
A patent troll, commonly known as a Non-Practicing Entity (NPE) or Patent Assertion Entity (PAE), acquires patents not for manufacturing, commercialization, or research purposes, but primarily to generate revenue through licensing demands and infringement litigation.
These entities typically:
- Do not manufacture products or provide services.
- Acquire broad or dormant patents.
- Target operating businesses with infringement claims.
- Leverage the high cost of litigation to obtain settlements.
Their business model depends on legal pressure rather than innovation.
Why Patent Trolls Matter
As India's innovation ecosystem expands across software, artificial intelligence, biotechnology, pharmaceuticals, electronics, and manufacturing, businesses increasingly face risks from patent assertion campaigns.
The threat is particularly significant for:
- Startups
- SMEs
- Technology companies
- Export-oriented businesses
- Companies operating in US and European markets
Even where infringement claims lack merit, defending litigation can be expensive and disruptive.
02 — Understanding the Threat
How Patent Trolls Operate
Patent trolls generally follow a predictable pattern:
Step 1 — Acquire Patents
They purchase patents from:
- Bankrupt companies
- Individual inventors
- Patent auctions
- Technology firms exiting a market
Step 2 — Identify Targets
Businesses developing commercially successful products become targets, particularly in technology-heavy sectors.
Step 3 — Send Legal Notices
The troll issues:
- Cease-and-desist letters
- Licensing demands
- Infringement notices
- Settlement proposals
Step 4 — Threaten Litigation
The objective is often not to win a lawsuit but to force an economically attractive settlement.
Types of Patent Trolls
Litigation Trolls
Acquire patents solely to initiate infringement suits and seek damages.
Licensing Trolls
Generate revenue through aggressive licensing campaigns without intending to litigate initially.
Shell Company Trolls
Operate through special-purpose entities that conceal the real owners and reduce litigation exposure.
Portfolio Aggregators
Accumulate large patent portfolios and pressure businesses into broad licensing arrangements.
Patent Assertion Entities (PAEs)
Professional organizations whose principal business model is patent enforcement.
Hybrid Trolls
Combine licensing, litigation, and portfolio strategies to maximize pressure on targets.
03 — The Law That Governs It
Indian Legal Safeguards
India's patent regime contains several provisions designed to discourage patent hoarding and abusive enforcement.
Section 84
Compulsory Licensing
Where patented inventions are not adequately worked in India, interested parties may seek compulsory licences.
Purpose: Prevent abuse of exclusive patent rights.
Section 107A
Research & Experimental Use
Provides statutory protection for certain experimental and research activities.
Purpose: Encourage innovation and scientific development.
Section 3(d)
Anti-Evergreening Provision
Restricts patent protection for minor modifications lacking enhanced efficacy.
Purpose: Prevent unjustified extension of patent monopolies.
Section 64
Revocation of Patent
Allows invalid patents to be challenged and revoked.
Grounds include:
- Lack of novelty
- Obviousness
- Wrongful obtaining
- Non-patentable subject matter
- Insufficient disclosure
Section 146
Working Statement Requirement
Patentees must disclose whether and how the invention is being commercially worked in India.
Purpose: Discourage patent warehousing.
Section 25(2)
Post-Grant Opposition
Interested parties may challenge a granted patent on statutory grounds.
Purpose: Remove weak or improperly granted patents from the register.
Designs Act, 2000
Patent-like assertion strategies occasionally involve industrial design registrations.
Under Section 19, a registered design may be cancelled if:
- It is not new or original.
- It was previously disclosed.
- It fails to satisfy statutory requirements.
- It does not qualify as a design under the Act.
04 — Practical Protection Strategy
1 Conduct Freedom-to-Operate (FTO) Searches
Before Product Launch
An FTO analysis identifies patents or designs that may affect commercialization.
Benefits include:
- Reduced infringement risk
- Better licensing decisions
- Early dispute avoidance
2 Monitor Patent Filings
Patent Watch Programs
Track:
- Competitor filings
- Emerging patent portfolios
- Industry-specific registrations
Key resources include:
- IP India
- WIPO PATENTSCOPE
- International patent databases
3 Build a Defensive IP Portfolio
Protect Before Others Do
File:
- Patent applications
- Design registrations
- Defensive publications
A strong portfolio creates leverage against potential assertions.
4 Challenge Weak Patents
Use Available Remedies
Where questionable patents are identified, businesses may:
- File post-grant opposition
- Seek revocation under Section 64
- Challenge validity during infringement proceedings
Weak patents are often the foundation of troll activity.
5 Obtain Early Legal Advice
Strategic IP Management
Professional guidance helps businesses:
- Assess infringement risks
- Respond to legal notices
- Negotiate licences
- Develop litigation strategies
Early intervention often prevents costly disputes.
05 — Case Study
Spice Mobiles & Samsung v. S. Somasundaram Ramkumar
One of India's most discussed patent enforcement disputes involved Patent No. 214388 relating to dual-SIM mobile phone technology.
The Dispute
The patent owner asserted rights against several mobile phone manufacturers and sought enforcement through customs actions and infringement claims.
The Challenge
Samsung and Spice Mobiles initiated revocation proceedings alleging:
- Lack of novelty
- Obviousness
- Anticipation by prior art
- Improper claim amendments
The Outcome
The Intellectual Property Appellate Board (IPAB) revoked the patent, finding:
- Prior art disclosures existed.
- The invention lacked inventive step.
- Certain amendments exceeded permissible limits.
Why It Matters
The case demonstrated:
- Importance of patent validity
- Availability of revocation mechanisms
- Risks of aggressive patent assertion
- Judicial scrutiny of weak patents

07 — Key Takeaways
Five Things Every Innovator Should Remember
01 Prevention Is Better Than Litigation
FTO searches and patent monitoring reduce future disputes.
02 Weak Patents Can Be Challenged
Indian law provides opposition and revocation mechanisms.
03 Build Your Own IP Portfolio
Strong IP rights provide strategic leverage.
04 Documentation Matters
Maintain records of development and innovation activities.
05 Seek Professional Advice Early
Early legal assessment is significantly less expensive than defending litigation.
08 — In Summary
Conclusion
Patent trolls represent a growing challenge for innovators, startups, and technology-driven businesses. While India's patent framework contains safeguards against abusive patent practices, businesses cannot rely solely on statutory protections.
A proactive approach—combining patent monitoring, Freedom-to-Operate analysis, defensive filings, and timely legal advice—remains the most effective defence. By understanding how patent trolls operate and using the remedies available under the Patents Act, 1970 and the Designs Act, 2000, businesses can protect innovation, reduce litigation exposure, and commercialize technology with greater confidence.
