`
`transmitting a selected required
`response from the response list in
`order to allow the message required
`response list to be cleared from the
`recipient’s cell phone display,
`whether said selected response is a
`chosen option from the response list,
`causing the forced message alert

`PDA/cell phones have automatically
`acknowledged receipt of a forced

`
`’838 Patent, Claim 1: A computer-
`implemented method comprising:
`performing, by a first device:
`joining a communication network
`corresponding to a group, wherein
`joining the communication network
`comprises transmitting a message
`including an identifier corresponding
`to the group;
`
`participating in the group, wherein
`participating in the group includes
`sending first location information to
`a first server and receiving second
`location information from the first
`server, the first location information
`comprising a location of the first
`device, the second location
`information comprising one or more
`locations of one or more respective
`second devices included in the
`group;
`
`presenting, via an interactive display
`of the first device, a first interactive,
`georeferenced map and a first set of
`one or more user-selectable symbols
`corresponding to a first set of one or
`more of the second devices, wherein
`the first set of symbols are positioned
`on the first georeferenced map at
`respective positions corresponding to
`the locations of the first set of second
`devices, and wherein first
`georeferenced map data relate
`positions on the first georeferenced
`map to spatial coordinates;
`
`sending, to a second server, a request
`for second georeferenced map data
`different from the first georeferenced
`map data;

`
`receiving, from the second server,
`the second georeferenced map data;
`
`presenting, via the interactive display
`of the first device, a second
`georeferenced map and a second set
`of one or more user- selectable
`symbols corresponding to a second
`set of one or more of the second
`devices, wherein the second set of
`symbols are positioned on the second
`georeferenced map at respective
`positions corresponding to the
`locations of the second set of second
`devices, and wherein the second
`georeferenced map data relate
`positions on the second
`georeferenced map to spatial
`coordinates; and
`
`identifying user interaction with the
`interactive display selecting one or
`more of the second set of user-
`selectable symbols corresponding to
`one or more of the second devices
`and positioned on the second
`georeferenced map and user
`interaction with the display
`specifying an action and, based
`thereon, sending third data to the
`selected one or more second devices
`via the first server.

`’838 Patent, Claim 19
`The method of claim 1, wherein
`participating in the group further
`includes sending first status
`information to the first server and
`receiving second status information
`from the first server, wherein the first
`status information comprises data
`indicative of a battery level of the
`first device, a signal strength of a
`wireless signal of the first device, a
