PAE is an acronym that stands for Patent Assertion Entity and it is also called Patent Troll. It is a situation where a company or business uses its own patent in generating income without providing or producing the products that the patent refer to. Most times, the patents are obtained from a third party, which is no longer interested in selling the product to the market or a company going under.
These businesses usually get their patent right from third parties and then seek to generate revenue by enforcing them against alleged defaulters.
