What Is Indirect Infringement?
Indirect infringement occurs when an individual or entity aids, induces, or contributes to another party’s direct infringement of a patent without actually performing the infringing act themselves. Unlike direct infringement, which requires direct use, making, selling, or importing of a patented invention, indirect infringement involves supporting or enabling infringement by a third party.
There are two primary types of Indirect Infringement:
- Induced Infringement – Encouraging, instructing, or assisting someone else to infringe a patent.
- Contributory Infringement – Providing a component, material, or product that has no substantial non-infringing use and is essential for patent infringement.
Why Indirect Infringement matters for Businesses and Patent Holders?
Indirect infringement laws are crucial for holding third parties accountable who enable patent violations without directly committing them. Key implications include:
- Legal liability – Even if a company doesn’t directly use a patented invention, it can still be sued for aiding infringement.
- Prevention of loopholes – Stops businesses from avoiding infringement claims by outsourcing or instructing others to infringe.
- Stronger patent enforcement – Patent holders can take legal action against multiple parties in the supply chain.
- Higher damages – Courts may impose significant financial penalties for knowingly enabling infringement.
How Indirect Infringement is proven?
1. Induced Infringement
The patent holder must prove that:
- The accused party actively encouraged, instructed, or facilitated another party’s Direct Infringement.
- The infringer knew about the patent and intended for infringement to occur.
- Direct Infringement actually took place as a result of their actions.
Example: A software company publishes a guide instructing manufacturers on how to replicate a patented encryption algorithm. If manufacturers follow the instructions and infringe the patent, the software company may be held liable for Induced Infringement.
2. Contributory Infringement
To establish contributory infringement, the patent holder must show that:
- The accused party supplied a component or product that has no substantial non-infringing use.
- The component was specifically designed for use in a patented invention.
- The accused party knew or should have known the component would be used in infringement.
Example: A company sells a specialized semiconductor chip that only functions within a patented medical device, knowing that customers will install it in an infringing product. Since the chip has no non-infringing use, the supplier could be held liable for Contributory Infringement.
Challenges in Indirect Infringement cases
While indirect Infringement laws prevent patent violations through third parties, proving liability can be difficult due to:
- Proving intent – The patent holder must demonstrate that the accused party knowingly induced or contributed to infringement.
- Establishing causation – There must be clear evidence that Direct Infringement occurred as a result of the accused party’s actions.
- Jurisdictional differences – Some countries do not recognize Indirect Infringement as a standalone offense.
- Complex supply chains – Identifying the responsible party in global manufacturing and distribution networks can be challenging.
Strategic Business use of Indirect Infringement Laws
Patent holders use Indirect infringement claims to:
- Prevent competitors from enabling infringement through third parties.
- Strengthen patent enforcement by holding multiple parties accountable.
- Monitor supply chains to ensure vendors and distributors are not involved in infringing activities.
- Negotiate stronger licensing agreements to reduce unauthorized use.
Key takeaways
- Indirect Infringement occurs when a party induces or contributes to another’s patent violation.
- Induced Infringement involves encouraging or instructing infringement, while Contributory Infringement involves supplying essential infringing components.
- Patent holders can hold multiple entities accountable in the supply chain, even if they do not directly infringe the patent.

Frequently Asked Questions
1. How does indirect infringement differ from direct infringement?
Direct infringement involves unauthorized use of a patented invention, while indirect infringement occurs when someone aids or facilitates the infringement. Unlike direct infringement, intent and knowledge of the patent are required for indirect infringement liability.
2. How can a company avoid indirect infringement liability?
Companies can conduct freedom-to-operate analyses, ensure compliance with patent laws, and avoid marketing or supplying products that enable infringement. If selling components, they must be suitable for substantial non-infringing uses to reduce risk.
