EMER 911 LOCATION DETECTION FOR MOBILE PHONES

The is a study of four patents related to emergency 911 processing based on the precise location of a mobile phone user.

Basis for Selection:

A lawsuit is pending with patent assignee EMSAT Advanced Geo-Location Technology against the companies in the mobile phone industry

Guideline Patent Number: 5,946,611 | Latest Date for Prior Art: December 25, 1990

Guideline Patent Filing Date: June 21, 1996| Owner(s): EMSAT Advanced Geo-Location Technology, LLC

Interested Parties: Sycord Limited Partnership, Location Based Services LLC, Acacia Research Corp., Leap Wireless International Inc., MetroPCS Communications, Centennial Communications Corp., Sprint Spectrum LP, Nextel Operations Inc. and all affiliated Nextel companies, ,Boost Mobile LLC, Boost Worldwide, Inc., Altel Corp., AT&T Mobility LLC, Metro PCS Communications, Metro PCS Wireless Inc., Cricket Communications, Inc., ETEX Telephone Cooperative Inc., ETEX Communication LP, United States Cellular Corp., T-Mobile USA, Inc., Cellco Partnership d/b/a Verizon Wireless.

Description:

The four patents share similar descriptions.  The FCC under a Phase II program for Emergency 911 service requires wireless carriers, within six months of a valid request by a PSAP (public safety answering point), to begin providing information that is more precise to PSAPs, specifically, the latitude and longitude of a mobile user.  This information must meet FCC accuracy standards.  The deployment of E-9-1-1 requires the development of technologies and upgrades to local 9-1-1 PSAPs.  

The patents potentially cover the technologies to implement this Phase II service and other location based services that rely on knowing the precise location of a mobile phone user.

Requirements to Match:

See the claims contained in the downloadable copies of the patents. The Latest Date for Prior Art for the patents of Dec. 25, 1990 reflects the most conservative approach for the date of eligible prior art. For some claims, prior art can have a date as late as March 13, 1995 So we encourage you to send prior art dated up to March 13, 1995. We will grant Advisor Points and determine on a claim by claim basis eligibility based on the date. 

Note, prior art search tip: later dated prior art can survey the history of the technology around the critical Latest Date for Prior Art and is a great search technique to understanding the earlier technical literature and identifying key scientists/inventors.
