Understanding Implied License by Equitable Estoppel: A Legal Overview
Definition & Meaning
An implied license by equitable estoppel is a legal concept that arises when a patent holder does not take timely action to enforce their patent rights against someone who is infringing those rights. This situation typically occurs when the patent holder has previously indicated, either directly or indirectly, that they will not pursue legal action against the infringer. As a result, the infringer may reasonably rely on this communication, believing that they are free to continue their actions without facing legal consequences. If the patent holder later decides to enforce their rights, the court may prevent them from doing so if it would unfairly harm the infringer.

Legal Use & context

Key legal elements
Real-world examples
Here are a couple of examples of abatement:
(Hypothetical example) A software company develops a program that unintentionally uses a patented algorithm. The patent holder learns of this but decides not to take action for several years, even after discussing the issue informally with the software company. The software company, believing it has the patent holder's tacit approval, continues to use the algorithm. If the patent holder later decides to sue, the court may find that they cannot do so due to equitable estoppel.
