A patent is an exclusive right, which most modern business owners leverage to optimize the commercialization of their intellectual property. The patent law enables a patentee to exclude others from making, using, selling, offering for sale or importing their patented invention without their consent. In case of any infringement the patentee is entitled to seek relief, which includes an injunction, damages or an account of profits.
Patent infringement occurs when an unauthorized party uses, makes, or sells a patented invention or process without permission from the patent owner. This can be a complex issue that involves legal and technical considerations. In this article, we will explore the different types of patent infringement and what they entail.
Literal Infringement
Literal infringement occurs when someone uses a patented invention or process in a way that is identical to the patent claims. This means that the infringing product or process matches the language in the patent claims, word for word. Literal infringement is the most straightforward type of patent infringement and is relatively easy to prove in court.
Doctrine of Equivalents Infringement
The doctrine of equivalents is a legal principle that states that an invention may still be considered infringing if it performs substantially the same function, in substantially the same way, to achieve substantially the same result as the patented invention. This means that even if the infringing product or process is not identical to the language in the patent claims, it may still be considered infringing if it is functionally equivalent. The doctrine of equivalents infringement can be more difficult to prove in court, as it requires an analysis of the similarities and differences between the patented invention and the infringing product or process.
Contributory Infringement
Contributory infringement occurs when someone provides the means for another party to infringe a patent. For example, if someone sells a component that is specifically designed to be used in an infringing product, they may be liable for contributory infringement. The key element of contributory infringement is that the accused party must have known, or should have known, that their actions would contribute to patent infringement.
Induced Infringement
Induced infringement occurs when someone actively encourages or aids another party to infringe a patent. For example, if someone provides instructions on how to make an infringing product, they may be liable for induced infringement. The key element of induced infringement is that the accused party must have intended to cause infringement.
Willful Infringement
Willful infringement occurs when someone is aware that they are infringing a patent but continues to do so anyway. This can lead to increased damages in court, as the plaintiff may be entitled to up to three times the damages they would receive for regular infringement. To prove willful infringement, the plaintiff must show that the accused party was aware of the patent and had no reasonable belief that their actions were legal.
Reverse Engineering Infringement
Reverse engineering infringement occurs when someone reverse-engineers a patented product or process without permission from the patent owner. Reverse engineering can be legal in some cases, such as when it is used to create interoperable products. However, if someone reverse-engineers a patented product or process and creates an infringing product, they may be liable for reverse engineering infringement.
