"Apple and Google have agreed to dismiss all the current lawsuits that exist directly between the two companies," the companies said in a joint statement. "Apple and Google have also agreed to work together in some areas of patent reform. The agreement does not include a cross license."
The deal does not appear to apply to Apple's ongoing litigation against South Korean rival
However, those victories have done little to slow the market share losses that Apple has experienced around the world to Samsung's phones, as well as other smartphones that run Android.
On Friday, Apple and Google told a federal appeals court in Washington that their respective cases against each other should be dismissed. The companies had at least 20 pending lawsuits in the U.S. and German courts that are now over.
The deal comes as Google prepares to shed Motorola. Earlier this year, Google said it was selling Motorola to Lenovo for $2.9 billion. That deal has not yet closed.

Both companies recently asked the Supreme Court to issue rulings that would make it easier for them to collect legal fees from entities that lose patent lawsuits. They believed that by raising the stakes for losing, companies would think twice before filing patent lawsuits.
