PAX is a royalty-free community patent cross-license that covers Android and Google applications preinstalled on devices that meet Android’s compatibility requirements.
The community licence has the backing of eight other members, including Samsung, LG and HTC.
According to PAX’s website, the nine companies own a collective total of more than 230,000 patents worldwide.
Joining the group will give members broad, long-term freedom of action with respect to Android and Google applications.
Google is also a part of a similar licensing community, the Open Invention Network.
The Linux defensive patent pool allows members to share patent rights, encourages collaboration and gives an expectation of freedom from patent aggression with the Linux system.
