In patent law, infringement occurs when a party without authorization exploits, uses, makes, sells, or imports a patented invention that falls within the scope of the claims of a valid and enforceable patent. Infringement is a violation of the exclusive rights granted to the patent holder and may result in legal action, including injunctions, damages, and other remedies. Here's an explanation of the different types of patent infringement:
Literal Infringement:
Literal infringement occurs when an accused product, process, or service directly matches all the elements or limitations of one or more claims of the patented invention. In other words, if the accused product or process incorporates every feature described in the patent claims, it infringes the patent.
Example: Suppose a patent claims a method for manufacturing a specific type of electronic device using a particular sequence of steps. If a competitor's manufacturing process exactly follows the sequence of steps described in the patent claims, it would constitute literal infringement.
Doctrine of Equivalents:
The doctrine of equivalents extends the scope of patent protection beyond literal infringement to cover variations or equivalents of the claimed invention that perform substantially the same function in substantially the same way to achieve substantially the same result.
This doctrine allows patent holders to prevent others from making minor modifications or substitutions to the accused product or process to avoid literal infringement while still achieving the same overall functionality or result.
Example: If a patent claims a specific chemical compound, the doctrine of equivalents may still find infringement if a competitor uses a slightly different chemical compound that performs the same function and achieves the same result.
Indirect Infringement:
Indirect infringement occurs when a party indirectly contributes to or induces infringement by another party. There are two types of indirect infringement:
a. Induced Infringement: Occurs when a party actively encourages, persuades, or induces others to infringe a patent.
b. Contributory Infringement: Occurs when a party provides a component, material, or product that is especially made or adapted for use in an infringing manner and is not a staple article or commodity of commerce suitable for substantial non-infringing uses.
Example: If a manufacturer sells a component specifically designed for use in a patented product, knowing that customers will use it to infringe the patent, the manufacturer may be liable for contributory infringement.
Direct Infringement of Method Claims:
Method claims cover processes or methods of doing something rather than physical products. Direct infringement of method claims occurs when someone performs all the steps of a patented method.
Example: If a patent claims a method for producing a chemical compound, performing each step of the method without authorization would constitute direct infringement.
In summary, patent infringement encompasses various forms of unauthorized use, exploitation, or replication of a patented invention, including literal infringement, infringement under the doctrine of equivalents, indirect infringement through inducement or contribution, and direct infringement of method claims. Patent holders have the exclusive right to prevent others from making, using, selling, or importing their patented inventions, and infringement actions provide legal recourse for enforcing these rights and protecting intellectual property.
