A patent violation occurs when someone uses, makes, sells, or distributes a patented invention without permission from the patent holder. Patents are legal protections granted to inventors, giving them exclusive rights to their inventions for a certain period. When these rights are infringed, the patent holder can take legal action against the violator. To prove a patent violation, the patent holder must demonstrate that the accused party has used the patented invention without authorization. This can lead to lawsuits, financial penalties, and the potential for the violator to stop using the invention. Legal processes often involve complex evaluations of the patent's claims and the alleged infringement.
