Geofence expert witness candidates typically have backgrounds in geofencing technology, software engineering, location based services, network communications, and may possess specialized knowledge in GPS or GIS.

A geofence is a virtual geographic perimeter that can be used with location-based services to trigger an alert, via software, when location data detects that a defined geofence has been crossed by a mobile device. The alert commonly contains the location of the device, and is sent to a mobile phone or email account.

Geofencing market applications include:

For a crime investigation, a geofence warrant can be issued by a court to give law enforcement access to records on mobile devices within a specific geofence area, including location history. There are concerns by some that this special search warrant violates privacy and Fourth Amendment rights.

Often, matters requiring geofence expert witness work involve patent infringement or trade secret litigation. Expert witness services by a geofencing expert could include an expert report, expert opinion, and/or trial testimony. In a high-profile case, or litigation involving a significant financial stake, an attorney may require a testifying expert with prior expert witness testimony experience. In addition, clients often seek an industry expert for pre-litigation consulting work.

While many experts have geofencing expertise, a geofence expert witness carries the additional responsibility of providing testimony before the court in a manner whereby jurors can understand the technology and evidence.
