It simply means that Google and Apple has agreed to stop all current lawsuits against each other (Google still owns the patents that Apple filed lawsuits on) at the moment. These lawsuits can restart any time. Apple and Google promises to work together on certain patent reform areas. IMO, that's most likely related to IP trolls, those two companies are in the top three list of companies constantly getting sued by IP trolls. Lenovo is not involved here.
