" Apple has also continued to add new products to the list of devices accused in that lawsuit. Three weeks ago, Apple added the Galaxy S III, Note and Note 10.1. It appears that Apple has already served its detailed infringement contentions concerning the S III and Note, but still needs to do so for the Note 10.1.
Apple furthermore notes that "the Android 4.1 Jelly Bean operating system" will become one of the accused technologies. That is interesting in light of Google's recent statement on the jury verdict in the first Apple v. Samsung litigation, where Google claimed that "[m]ost of these [patent claims] don't relate to the core Android operating system". I commented on the "core Android" question in a recent post."
