Google and Android companies (including Samsung and LG) recently announced a new patent software sharing agreement (Android Networked Cross-License) called PAX (meaning peace in Latin) which aims to defend them against future software patent lawsuits.
The agreement covers free patent software sharing on Android and Google Applications on multiple devices. The type of patents that will be shared under the licensing agreement are not yet known. The agreement is however expected to open up the Android ecosystem to smaller companies and make it harder for patent trolls to target Samsung.
