What is a Patent Assertion Entity (PAE)?

A PAE, often called a patent troll, is an organization that acquires patents not to use them in products, but to assert them against others, usually through licensing demands or litigation.

How does the Open Invention Network (OIN) protect open source software?

OIN provides a defensive patent royalty-free patent license agreement for core Linux technologies, protecting participating companies from patent infringement claims related to Linux and adjacent open source projects.

Will this mean fewer patent lawsuits?

While OIN's efforts are making open source a tougher target for PAEs, it's unlikely to eliminate patent lawsuits entirely. However, it could significantly reduce the number of assertions specifically targeting the open source community.
