Exploring Implied License: Legal Insights and Implications

Definition & Meaning

An implied license is a type of license that allows someone to use another person's property without explicit permission. This license can arise from the actions or conduct of the property owner, even if they have not formally granted permission. In the context of patent law, an implied license may occur when a patent holder's behavior suggests they have given permission for others to use their patent, particularly if they encourage the manufacture or sale of products that infringe on their patent claims. When a patent holder sells a product or grants a license to a buyer, that buyer may also have the right to resell the product, creating an implied license for subsequent buyers.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A homeowner allows a neighbor to use their driveway for parking without a formal agreement. This conduct may create an implied license for the neighbor to park there.

Example 2: A software developer sells a program and does not restrict the buyer from sharing it. The buyer may have an implied license to distribute the software to others. (hypothetical example)
