3.  Electronic Tag Game ◦ Wireless RF communication specifically designed for communicating location data ◦ “Tag” occurs when players get close to each other  Light-Operated Toy Shooting Game ◦ IR light projection ◦ Not capable of communicating player information via IR to distinguish who hit who  Electronic Game with Infrared Emitter and Sensor ◦ Encoded IR light projection to communicate data ◦ Pistol-shaped housing

4.  Electronic Tag Game ◦ “Tag” data is communicated via IR (not RF or Bluetooth) ◦ “Location” data is not communicated at all  Light-Operated Toy Shooting Game ◦ IR light projection is not encoded so IR communication is implemented in a substantially different way.  Electronic Game with Infrared Emitter and Sensor ◦ IR light projection is encoded with individual user information ◦ Pay royalty fees No Infringement Infringement
