Prior art

I am unable to provide a comprehensive list of the most relevant prior art for US Patent 9854402 by directly citing each patent reference. The "Full patent text" provided, which was fetched from Google Patents, does not include the standard "Prior art references" or "Cited patents" section that typically lists the documents cited during prosecution. My search capabilities do not allow me to browse or extract this specific section from the live Google Patents webpage or the USPTO database for US9854402.

Therefore, I cannot fulfill the request to provide the full citation, publication/filing date, brief description, and potential claim anticipation for each patent citation.

However, the provided patent text itself describes certain existing technologies that it considers prior art in its "Definitions" section and background discussion, highlighting the problems that the invention aims to solve. Based on these descriptions, the patent acknowledges the following prior art:

• One-way location sharing services: This includes systems like On Star and Mercedes Benz TeleAid, which use GPS receivers and cellular phone capabilities within a car to allow an aid center to track vehicles, communicate with occupants, and detect events like airbag deployment. These systems are characterized as "one way location sharing" because the occupants of the car do not know the location of the aid center.
• Commercial kid tracking systems: Other existing commercial services enable parents to track the locations of their children in a one-way manner. A key limitation highlighted is that "None of these services allow ... the children to know where their parents are." Additionally, "the prior art kid tracking systems could not be reconfigured in the field to add new individuals with whom location information was to be shared."

The patent emphasizes a "need" for systems that allow mutual location sharing and on-the-fly reconfiguration of sharing groups, which these described prior art systems lacked.

Without access to the actual cited patent documents, a specific anticipation analysis under 35 U.S.C. § 102 for individual claims of US9854402 against formal prior art citations cannot be performed. The independent claims (Claims 1, 2, and 12) of US9854402 focus on a mutual location sharing system with a central server, encryption, map display, and dynamic group management, which directly addresses the shortcomings of the one-way and inflexible systems described as prior art in the patent's specification.
