In November 2012 Patent Bolt published a Samsung patent application report regarding "Air-Gesturing.". Air Gesturing for handheld devices could be an option for specific Android applications and the idea behind this feature is to control the User Interface without having to actually touch the display. During last night's boring Samsung Galaxy S4 event, they introduced this feature, fulfilling their patent which hints of this feature eventually sliding over to future Samsung Smart Televisions. Additionally, Samsung introduced their "Smart Scroll" smartphone feature last night which fulfilled one of their latest trademarks filings.
On another IP note, Samsung introduced a feature called WatchON last night and this morning the trademark filing for that was published by the US Patent and Trademark Office.
